All-sky modeling of Galactic emission at radio and microwave frequencies

Gabriel A. Hoerning, Clive Dickinson, Stuart E. Harper +13

We present a new all-sky model of low-frequency diffuse Galactic emission in the regime where synchrotron, free-free, and spinning dust dominate. The model extends the Planck 2015…

A comparison between Galactic magnetic field models and polarized synchrotron emission with C-BASS at 4.76 GHz and S-PASS at 2.3 GHz

Vasundhara Shaw, S. E. Harper, C. Dickinson +9

We compare a set of contemporary Galactic magnetic field (GMF) models with polarized synchrotron observations from the S-PASS and C-BASS radio surveys and combine them to create a…

Spectral Properties of Anomalous Microwave Emission in 144 Galactic Clouds

Roke Cepeda-Arroita, J. A. Rubiño-Martín, R. T. Génova-Santos +23

Anomalous Microwave Emission (AME) is a diffuse microwave component thought to arise from spinning dust grains, yet remains poorly understood. We analyze AME in 144 Galactic clouds…

Separation of gain fluctuations and continuum signals in total power spectrometers with application to COMAP

J. G. S. Lunde, P. C. Breysse, D. T. Chung +11

We describe a time-domain technique for separating gain fluctuations and continuum signal for a total power spectrometer, such as the CO Mapping Array Project (COMAP) Pathfin…

COMAP Pathfinder -- Season 2 results I. Improved data selection and processing

J. G. S. Lunde, N. -O. Stutzer, P. C. Breysse +24

The CO Mapping Array Project (COMAP) Pathfinder is performing line intensity mapping of CO emission to trace the distribution of unresolved galaxies at redshift . We pres…

COMAP Pathfinder -- Season 2 results II. Updated constraints on the CO(1-0) power spectrum

N. -O. Stutzer, J. G. S. Lunde, P. C. Breysse +24

We present updated constraints on the cosmological 3D power spectrum of carbon monoxide CO(1-0) emission in the redshift range -. The constraints are derived from the two…
