SUMMARY:Unifying foreground emission characterisation across the radio and
  microwave regimes: implications for cosmology - Dr. Melis Irfan (Institut
 e of Astronomy\, University of Cambridge)
DTSTART:20250121T111500Z
DTEND:20250121T120000Z
UID:TALK224713@talks.cam.ac.uk
CONTACT:Charles Walker
DESCRIPTION:The next generation of Cosmic Microwave Background experiments
  are poised to probe the inflationary period of the Universe through the m
 easurement of primordial B-modes\, whilst 21cm experiments are observing t
 he reionization history of the early Universe and formation of Large Scale
  Structure through the mapping of neutral hydrogen. These two complementar
 y fields span the radio to microwave frequency regimes and share a pivotal
  data reduction task: foreground component separation. In this talk I will
  discuss the latest understanding around diffuse and compact foreground em
 issions from MHz to GHz frequencies and how the recent increase in empiric
 al data coupled with technical advances in methodologies (e.g. kernel proc
 esses\, machine learning and sparsity) are taking us closer to a unified m
 odel of foreground emissions that can be utilised by multiple communities 
 within the field of cosmology.
