SUMMARY:Testing General Relativity with 21 cm intensity mapping - Alex Hal
 l (KICC Cambridge)
DTSTART:20121112T130000Z
DTEND:20121112T140000Z
UID:TALK39638@talks.cam.ac.uk
CONTACT:Camille Bonvin
DESCRIPTION:I investigate the prospects for constraining alternative theor
 ies of gravity with a new observational technique\, the 21 cm intensity ma
 p. I will discuss the merits of this approach\, and demonstrate the existe
 nce of new large-scale contributions to the signal from relativistic effec
 ts. I will also address the issue of how best to parameterise modified gra
 vity in the cosmological setting.\n
