SUMMARY:The dark side of massive galaxies and new light with JWST\, As
 tronomy Colloquium\, Christina Williams\, NOAO
DESCRIPTION:Our most powerful telescopes have glimpsed galaxies in the
 ir early growth phase only a few billion years after the Big Bang. Sur
 prisingly\, galaxy surveys show that the most massive galaxies in the 
 Universe were formed the earliest in cosmic time\, in extreme but shor
 t-lived bursts of star-formation. I will discuss my research into the 
 unknown astrophysics that drives\, and abruptly ends\, the extreme liv
 es of massive galaxies. By integrating uniquely deep ALMA and optical/
 infrared imaging\, I will present new insights into the growth rates a
 nd gas reservoirs of both quiescent and dusty star-forming massive gal
 axies during their early evolution. This research will soon take a lea
 p forward using JWST\, which will unveil the hidden astrophysics of ea
 rly galaxy growth with the deepest infrared imaging and spectroscopy e
 ver taken.  I will conclude with an overview of two galaxy surveys I w
 ill co-lead during the first year of JWST and forcast how they will co
 ntribute to outstanding questions about the life cycle of massive gala
 xies.
