SUMMARY:Creating a physically accurate CEM model of the REACH for global 2
 1-cm cosmology - Dr. John Cumner (Cavendish Astrophysics)
DTSTART:20251111T111500Z
DTEND:20251111T120000Z
UID:TALK236848@talks.cam.ac.uk
CONTACT:Charles Walker
DESCRIPTION:I shall discuss gain pattern modelling with respect to observa
 tional 21-cm science. A focus will be placed upon how our knowledge of the
  physical structure of our instruments can impact their ability to success
 fully perform a detection of the 21-cm signature from the early universe. 
 As an example case I shall discuss the REACH dipole radiometer\, currently
  observing in the Karoo radio reserve South Africa\, including the evoluti
 on of the construction and CEM models until this point and an overview of 
 what is currently being done to calibrate and compensate for the gain patt
 ern of the instrument.
