DESCRIPTION:Speakers: Cecilia Lunardini ()\nI will review the physics of n
 eutrinos from core collapse\nsupernovae\, with highlights of recent advanc
 es in this field. Emphasis will be placed on how to improve the theory of 
 neutrino emission and propagation\, and on the physics potential of the ne
 xt generation ofneutrino detectors. Different regimes will be discussed\, 
 ranging from a very high statistics observation of a nearby supernova\, to
  the quasi-diffuse or diffuse flux detection from several very distant col
 lapsing stars.  New directions involving multi-messenger observations of s
 upernovae (with neutrinos\, photons and gravitational\nwaves) will be pres
 ented.\n\nhttps://indico.ific.uv.es/event/3427/contributions/10596/

SUMMARY:Signatures of Primordial Black Holes in 21cm Cosmology

DESCRIPTION:Speakers: Samuel Witte (IFIC)\nCurrent and near future 21cm co
 smological surveys promise to offer a wealth of information about state of
  the Universe during the early stage of reionization and the cosmic dawn\,
  cosmological epochs which have yet to be directly probed. The 21cm signal
  produced during these epochs is remarkably sensitive to the state of the 
 IGM\, and thus can provide a strong probe of any exotic model that modifie
 s either the temperature evolution of the medium or the formation of struc
 ture. In\nthis talk I will focus on the potential signatures arising from 
 a\npopulation of ~ solar mass primordial black holes (PBHs) that account f
 or a subdominant fraction of the dark matter. I will illustrate three dist
 inct effects produced by these PBHs and comment on the expected sensitivit
 y to the 21cm power spectrum from experiments like HERA\n(Hydrogen Epoch o
 f Reionization Array) and SKA-Low\, showing that 21cm observations may imp
 rove existing constraints by multiple orders of magnitude. Should time per
 mit\, I will comment on techniques being developed that will allow for a g
 reater weather of information to be extracted from the data\, and will gre
 atly ease computational difficulties associated with predicting the 21cm s
 ignal at high redshifts.\n\nhttps://indico.ific.uv.es/event/3427/contribut
