SUMMARY:Primordial black holes in the dark ages - Daniel Wesley (DAMTP)

DESCRIPTION:Future observations promise to unveil cosmic history during th
 e "dark ages\," between roughly z=30 and 800.  Observations of 21cm radiat
 ion are especially suited to detecting the ionisation history and thermal 
 properties of the intergalactic medium (IGM) during this period.  I will d
 escribe how primordial black holds (PBHs) would affect the IGM during the 
 dark ages\, which can lead to better constraints on potential PBH populati
 ons.  I will\nalso explain some unique PBH observational signatures that c
 an distinguish them from other sources of IGM energy injection\, such as d
 ecaying dark matter.\n
