Welcome to the COSMOLOGY WITH THE CMB AND ITS POLARIZATION workshop
We are delighted to host the workshop, “Cosmology with the CMB and its Polarization” held in downtown Minneapolis on Wednesday, January 14th to Friday, January 16th 2015 sponsored by our William I. Fine Theoretical Physics Institute. The purpose of the workshop is to assemble the US and international CMB community to assess the current status of experimental and theoretical studies, and to look forward to the future.
The workshop will start with several presentations on the full mission Planck results. There will then be a full review of the status of ground based and sub-orbital experimental programs, and of current theoretical aspects. We will also have a report on the upcoming European M4 proposal for a post-Planck space mission and a discussion about NASA’s plans for CMB and participation in M4. The workshop will end with a discussion regarding the next generation CMB S4 polarization project recently endorsed by the US P5 HEP advisory committee. With all the current activity in the field it should be an exciting meeting!

Signals and degeneracies of the primordial power spectrumUsing the temperature data from Planck we search for departures from a power-law primordial power spectrum, employing Bayesian model-selection and posterior probabilities. We parametrize the spectrum with n knots located at arbitrary values of log k, with both linear and cubic splines. This formulation recovers both slow modulations and sharp transitions in the primordial spectrum. The power spectrum is well-fit by a featureless, power-law. A modulated primordial spectrum yields a better fit relative to ΛCDM at large scales, but there is no strong evidence for a departure from a power-law spectrum. Moreover, using simulated maps we show that a local feature can mimic the suppression of large-scale power. With multi-knot spectra we see only small changes in the posterior distributions for the other free parameters in the standard ΛCDM universe. We explore the degeneracy with other features of primordial power spectrum suppression, namely the effects of massive neutrinos.

Polarization Measurements with the South Pole TelescopeI will give an overview of the SPTpol and SPT-3G experiments. SPTpol is a polarization-sensitive camera designed to measure the polarization of the cosmic microwave background (CMB) deployed on the 10 meter South Pole Telescope (SPT) in January 2012. I will present recent results of the E-mode and TE-mode CMB power spectra, derived from 100 square degrees observed in the first year of observations. Additionally I will show B-mode power spectra, measurements of the gravitational lensing potential, and briefly report on the status of the full 500 square degree SPTpol survey. Finally, I will discuss the status of SPT’s next-generation camera, SPT-3G, which will consist of 16,200 polarization-sensitive transition-edge sensors (TES), contained within 2700 multi-chroic pixels with observing bands centered at 95, 150, and 220 GHz, and scheduled to achieve first light in January 2016.

Planck and post-Planck SimulationsSimulations play a critical role in CMB experiments, including optimizing instrument design and deployment, validating and verifying data analysis algorithms and implementations, and debiasing and uncertainty quantification of the analysis results. Generating simulation sets also poses significant challenges, both in ensuring that they faithfully reproduce the critical characteristics of an experimental dataset, and in optimizing their generating to allow for the production of very large ensembles of realizations for Monte Carlo analyses. In this talk I will describe these challenges in the context of the simulation pipeline used in support of the 2nd Planck data release, outline the resulting dataset and its possible extension to support post-Planck experiments, and comment on the developments that will be needed for the next generation of mission-class CMB experiments such as CMB-S4, LiteBIRD and COrE+.

The astrophysics of dust polarizationThe Planck satellite has produced the first whole sky map of polarization|at sub-mm and mm wavelengths. This is an immense step forward from|earlier polarization observations of Galactic dust. The data is revealing a new|sky we have started to explore. For the first time, we have the data needed to characterize the structure of the Galactic magnetic field and its coupling with interstellar matter and turbulence, in the diffuse interstellar medium and molecular clouds. Our analysis of the data also involves the characterization of the polarization properties of dust. I will introduce the science questions we are investigating and review our published results. I will connect what we are learning on the astrophysics of dust polarization to the structure of the dusty polarized screen to CMB polarization at high Galactic latitudes.

The Large Scale Polarization ExplorerThe LSPE is a balloon-borne mission aimed at measuring the polarization of the Cosmic Microwave Background (CMB) at large angular scales, and in particular to constrain the curl component of CMB polarization (B-modes) produced by tensor perturbations generated during cosmic inflation, in the very early universe. Its primary target is the detection of the power spectrum of B-modes at multipoles covering both the reionization peak and the recombination peak, with a sensitivity corresponding to r = 0.02, at 99.7% confidence. A second target is to produce wide maps of foreground polarization generated in our Galaxy by synchrotron emission and interstellar dust emission. These will be important to map Galactic magnetic fields and to study the properties of ionized gas and of diffuse interstellar dust in our Galaxy. The mission is optimized for large angular scales, with coarse angular resolution (around 1.5 degrees FWHM), and wide sky coverage (25% of the sky). The payload will fly in a circumpolar long duration balloon mission during the polar night. Using the Earth as a giant solar shield, the instrument will spin in azimuth, observing a large fraction of the northern sky. The payload will host two instruments. An array of coherent polarimeters using cryogenic HEMT amplifiers will survey the sky at 43 and 90 GHz. An array of bolometric polarimeters, using large throughput multi-mode bolometers and rotating Half Wave Plates (HWP), will survey the same sky region in three bands at 140, 220 and 240 GHz. The wide frequency coverage will allow optimal control of the polarized foregrounds, with comparable angular resolution at all frequencies.

SPHEREx: An All-Sky Spectral Survey to Probe Inflation SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) is a proposed all-sky spectroscopic survey satellite designed to address all three science goals in NASA’s Astrophysics Division: probe the origin and destiny of our Universe; explore whether planets around other stars could harbor life; and explore the origin and evolution of galaxies. SPHEREx will scan a series of Linear Variable Filters systematically across the entire sky. The SPHEREx data-set will contain R=40 spectra spanning the near infrared(0.75$\mu$m$<\lambda<$4.83$\mu$m) for every 6.2 arcsecond pixel over the entire-sky. In this paper, we detail the extra-galactic and cosmological studies SPHEREx will enable and present detailed systematic effect evaluations.

The Cosmology Large Angular Scale Surveyor (CLASS)The Cosmology Large Angular Scale Surveyor (CLASS) is an experiment to measure the imprint of gravitational waves from inflation in the polarization of the cosmic microwave background. CLASS is a multi-frequency array of four telescopes to be deployed in the Atacama Desert in Chile. From this site, CLASS will observe 70% of the sky at four frequency bands centered at 38, 93, 148, and 217 GHz - designed to straddle the full-sky galactic foreground minimum. The large survey area enables CLASS to characterize the B-mode and E-mode power spectra on both the reionization and recombination scales. Simulations including the presence of foregrounds suggest the CLASS strategy of combining large sky coverage, control of systematic errors, signal stability, and high sensitivity will allow detection of the tensor-to-scalar ratio down to the level of r=0.01 and enable cosmic-variance-limited measurements of the optical depth to reionization. In this talk, I present an overview of the CLASS strategy for measuring the E-modes and B-modes at the largest angular scales and give an update on the project status.

PIXIETalk will include an examination of systematic effects of emission from mirrors,calibrator, grids and other areas within the PIXIE instrument. The systematiceffects of detector non-ideality and asymmetry will also be presented. Theseshow that the residual systematic effects do not jeopardize either the polarization or spectrum measurements and that there are sufficient safeguards to find andcalibrate out the most likely errors.

Did m2φ2 bite the dust? A closer look at ns and r I will review measurements of the angular power spectrum of temperature perturbations from Planck data by the Planck collaboration and by Renee Hlozek, David Spergel and myself and will discuss the small differences in the scalar spectral index between the two. I will then combine these measurements with the recent measurement of the polarization of the cosmic microwave background by BICEP2 as well as the measurements of polarized emission from dust by the Planck collaboration to derive the current (but soon outdated) constraints on the spectral index of scalar perturbations and the amount of primordial gravitational waves. I will show that the data now disfavors the simplest model of inflation at 2-3 sigma depending on the choice of likelihood for the temperature data.

A First Post-flight Update on the SPIDER MissionThe SPIDER balloon-borne polarimeter has been deployed to McMurdo, Antarctica, from where it will fly in December 2014. A second flight, featuring a different frequency coverage, is scheduled for December 2016. Careful control of instrumental systematics and a scanning strategy optimized to reduce the error in the reconstruction of the Stokes parameters will allow for a 3-sigma detection, in the presence of Galactic foregrounds, of the primordial B-mode signal in the Cosmic Microwave Background, provided that the tensor-to-scalar ratio r be greater than 0.03. SPIDER’s first flight will already provide competitive constraints; if polarized foreground emissions were negligible in the SPIDER field, we would detect the r=0.03 primordial B-mode signal after our first flight.

Probing the Inflationary Universe with the LiteBIRD SatelliteLiteBIRD is a satellite to map the polarization of the CMB radiation over the full sky at large angular scales with the ultimate precision. Cosmological inflation, which is the leading hypothesis to resolve the problems in the Big Bang theory, predicts that primordial gravitational waves were created during the inflationary era. Measurements of polarization of the CMB radiation are known as the best probe to detect the primordial gravitational waves. The LiteBIRD working group is authorized by the Japanese Steering Committee for Space Science (SCSS) and is supported by JAXA. It has about 70 members from Japan, USA, Canada and Germany. Studies in the working group are in progress toward the mission definition review, with a target launch year in early 2020’s. The scientific objective of LiteBIRD is to test all the representative inflation models that satisfy single-field slow-roll conditions and lie in the large-field regime. To this end, the requirement on the precision of the tensor-to-scalar ratio, r, at LiteBIRD is equal to or better than 0.001. In case of large r values, as suggested by BICEP2, LiteBIRD will be able to scrutinize the power spectrum of the B-mode polarization to further narrow-down inflationary models. The design of the LiteBIRD system is driven by these scientific goals. A 3-year full sky survey will be carried out for at least 6 frequency bands between 50 and 320 GHz to achieve the total sensitivity of 1.8 microKarcmin with the angular resolution of 30 arcmin at 150 GHz. The key components of the mission payload include a half-wave plate system for signal modulation, two reflective mirrors with a diameter of about 60 cm, an array of superconducting polarimeters with distributed band centers for precise foreground removal, the readout system with high multiplexing factors in the frequency domain, and the cryogenic system to provide the 100 mK base temperature.

The Primordial Inflation Polarization Explorer (PIPER)The Primordial Inflation Polarization Explorer (PIPER) is a balloon-borne instrument to search for inflationary B modes on angular scales 30 arcmin to 90 degrees (2 < ell < 400). PIPER combines cold (1.5 K) optics, 5120 bolometric detectors, and rapid polarization modulation using VPM grids to achieve both high sensitivity and excellent control of systematic errors. A series of flights alternating between northern and southern hemisphere launch sites will produce maps in Stokes I, Q, U, and V parameters at frequencies 200, 270, 350, and 600 GHz (wavelengths 1500, 1100, 850, and 500 microns) covering 85% of the sky. We describe the PIPER instrument and discuss the current status and expected science returns from the mission.

The POLARBEAR / Simons Array We will describe recent cosmic microwave background (CMB) results from the POLARBEAR-1 experiment and the future evolution of the POLARBEAR experiment to the Simons Array. POLARBEAR-1 has made a high significance detection of the B-mode gravitational-lensing deflection spectrum and a measurement of the “BB” B-mode autospectrum. We will describe a stringent set of tests for systematic errors and upper limits on foreground contamination. Finally, we will describe the Simons Array which will have three identical 3.5 meter diameter telescopes with a set of three bolometric array receivers that will have 22,764 bolometers distributed among 90, 150, and 220 GHz. The science goals include a deep search for the inflationary B-mode signal at degree-angular scales and a large-area survey to characterize gravitational lensing.

Odd tensor modes from inflationThe existence of a primordial spectrum of gravitational waves is a generic prediction of inflation. Here I will discuss how the coupling of a pseudoscalar inflaton to a gauge field can induce, in a two-step process, gravitational waves with unusual properties such as: (i) a net chirality (ii) a blue spectrum (iii) being detectable in the (relatively) near future by ground-based gravitational
