DESCRIPTION:Speakers: Daniel Mortlock (Imperial College London)\n\nQuasars
  - accreting super-massive black holes - are the most luminous non-transie
 nt sources known and can be seen at redshifts of z > 7\, when the Universe
  was just ~5% of its current age.  This implies that black holes with mas
 ses of up to ~10^9 M_Sun formed less than 800 Myr after the Big Bang\, imp
 ossible under the default paradigm of Eddington-limited accretion onto ste
 llar mass black holes.  The greatest barrier to understanding the formati
 on and growth of these objects is the lack of data: quasars are very rare 
 at these distances/times with fewer than ten known with z > 7 at present.
   I will report on recent observational developments in this field\, with
  a particular focus on the early results from the Euclid mission\, for whi
 ch the Wide Survey has the necessary combination of area\, wavelength cove
 rage and depth to increase the number of known quasars by an order of magn
 itude and to push to redshifts z > 8 and beyond.\n\nhttps://events.perimet
