SUMMARY:The Dark Side of the Cosmic Dawn
DESCRIPTION:Featuring Tracy Slatyer \, Massachusetts Institute of Technolog
	y\n\nPart of the HET Seminar Series.\n\nDark matter constitutes more than 5
	/6 of the matter in the universe\, but its nature and interactions remain o
	ne of the great puzzles of fundamental physics. Dark matter collisions or d
	ecays have the potential to produce high-energy particles; such particles m
	ay already have reshaped the history of our cosmos\, leaving traces of thei
	r existence in ionization and heating of the intergalactic medium\, and in 
	background radiation from the cosmic dark ages and the epoch of reionizatio
	n. I will discuss a new public Python package\, DarkHistory\, for exploring
	 these possible signatures of dark matter physics in cosmological observati
	ons. DarkHistory simultaneously solves for the evolution of the ionization 
	level and gas temperature\, and for the cooling of particles produced by da
	rk matter processes\, allowing a self-consistent treatment of conventional 
	and exotic sources of heating and ionization.
