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…
A vision for ground-based astronomy beyond the 2030s: How to build ESO's next big telescope sustainably
Laurane Fréour, Mathilde Bouvier, Tony Mroczkowski +8
Astronomy is the study of the Universe and all the objects that it comprises. Our attention is therefore usually focused beyond Earth, home to the only form of life known today. Ho…
Influence of the Galactic Halo on the UHECR Multipoles
Vasundhara Shaw, Arjen Van Vliet, Andrew M. Taylor
We examine the effects of a giant magnetized halo around the Galaxy on the angular distribution of the arriving ultra-high energy cosmic rays (UHECR) observed at Earth. We investig…
The Polarisation Sky Survey of the Universe's Magnetism (POSSUM): Science Goals and Survey Description
B. M. Gaensler, G. H. Heald, N. M. McClure-Griffiths +57
The Australian SKA Pathfinder (ASKAP) offers powerful new capabilities for studying the polarised and magnetised Universe at radio wavelengths. In this paper, we introduce the Pola…
