DESCRIPTION:Speakers: Naman Jain (McGill University)\nFast radio bursts (F
 RBs) are energetic millisecond-duration bursts with extragalactic origins.
  Roughly 4000 unique sources have been observed to date\, about 3% of whic
 h have been seen to repeat\, though it remains unclear whether all FRBs re
 peat.\nAn FRB population study addresses several key questions: How often 
 do FRBs occur in the universe? What energy and redshift distributions do t
 hey follow? Is their occurrence correlated with the cosmic star formation 
 history (SFH)? Answering these questions helps contextualize the origins o
 f FRBs with potential astrophysical sources such as magnetars and supernov
 ae.\nPrevious population studies\, based on samples of a few hundred sourc
 es\, have provided important constraints on FRB rates and energetics. Howe
 ver\, these analyses were limited by smaller sample sizes\, less well-char
 acterized selection effects\, and uncertain treatment of repeat bursts.\nT
 he recently released Second CHIME/FRB Catalog contains more than 90% of al
 l known FRB sources (≈3600) and provides well-calibrated selection effec
 ts. We leverage this sample to infer key FRB properties\, including the vo
 lumetric rate\, energy function\, redshift distribution\, and correlation 
 with the cosmic SFH. We then compare the predicted energetics and abundanc
 es with proposed FRB models and contrast the inferred redshift distributio
 ns with those of FRBs with known host galaxies.\n\nhttps://nyx.physics.mcg
