The Second Radio Synchrotron Background Workshop: Conference Summary and Report by J. Singal et al. on Wednesday 30 November

We summarize the second radio synchrotron background workshop, which took

place June 15-17, 2022 in Barolo, Italy. This meeting was convened because

available measurements of the diffuse radio zero level continue to suggest that

it is several times higher than can be attributed to known Galactic and

extragalactic sources and processes, rendering it the least well understood

electromagnetic background at present and a major outstanding question in

astrophysics. The workshop agreed on the next priorities for investigations of

this phenomenon, which include searching for evidence of the Radio

Sunyaev-Zeldovich effect, carrying out cross-correlation analyses of radio

emission with other tracers, and supporting the completion of the 310 MHz

absolutely calibrated sky map project.
