SUMMARY:The High-z Transient Universe with JWST - Armin Rest

DESCRIPTION:Over the last two decades\, high-cadence rolling surveys (e.g.
 \, PS1\, ZTF\, ATLAS) have given us large statistical samples of supernova
 e (SNe) and other transients in the low-z range up to redshifts of 1. With
  JWST\, going deeper and redder\, we can now expand transient astronomy in
 to the early\, high-z universe. Such unique observation on high-z transien
 ts offers us a direct approach for probing the IMF at high-z\, the epoch o
 f reionization\, as well as exploring the cosmological expansion history. 
 Those sample can also provide insights into the rare types of transients (
 e.g.\, Pair-Instability SNe and Superluminous SNe) and could deepen our un
 derstanding in high energy physics and explosion mechanisms underneath.  I
  will discuss our recent discovery of more than 100 SNe up to z~5 with the
  JADES and COSMOS project\, their spectroscopic follow-up\, and what we ca
 n expect in the future with both JWST and Roman.
