Probing Anomalous Microwave Emission with the Square Kilometre Array
MatÃas Vidal, Simón Casassus, Roke Cepeda-Arroita +15
Anomalous microwave emission (AME) represents an excess of radiation in the 10-60 GHz range, distinct from synchrotron, free-free, or thermal dust emission. Although most commonly…
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-MartÃn, 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…
The BINGO project X. Cosmological parameter constraints from HI Intensity Mapping lognormal simulations
Pablo Motta, Filipe B. Abdalla, Camila P. Novaes +12
Context. Building on the transformative success of optical redshift surveys, the emerging technique of neutral hydrogen (HI) intensity mapping (IM) offers a novel probe of large-sc…
COMAP Pathfinder -- Season 2 results IV. A stack on eBOSS/DESI quasars
D. A. Dunne, K. A. Cleary, J. G. S. Lunde +16
We present a stack of data from the second season of the CO Mapping Array Project (COMAP) Pathfinder on the positions of quasars from eBOSS and DESI. COMAP is a Line Intensity Mapp…
