SUMMARY:Blown away: relative velocities and the first galaxies - Luke Cona
 boy (Nottingham)
DTSTART:20231110T113000Z
DTEND:20231110T123000Z
UID:TALK205054@talks.cam.ac.uk
CONTACT:Sandro Tacchella
DESCRIPTION:Supersonic relative velocities between baryons and dark matter
  in the nascent Universe affect the formation and growth of the first gala
 xies\, by impeding the accretion of gas into the potential wells of the da
 rk matter haloes. In turn\, this can delay the onset of the formation of t
 he first stars and as such is an important effect  to consider in the cont
 ext of the first galaxies. I will talk about our work self-consistently sa
 mpling the relative velocity in a cosmological zoom simulation and discuss
  some future avenues of exploration.
