The Cosmic Ultraviolet Baryon Survey (CUBS) is a large HST Cycle 25 GO
program designed to map 'dark' baryonic structures in the crucial but
unconstrained epoch between redshift z = 0.4 and z ~ 2.  The CUBS
program aims to combine absorption-line spectroscopy of 15 UV-bright
QSOs at z > 0.8 with matching deep galaxy survey data.  This legacy
sample enables systematic studies of the co-evolution of galaxies and
diffuse circumgalactic and intergalactic gas at a time when the star
formation rate density undergoes its most dramatic changes, and
provide key insights into how galaxy growth is regulated by accretion
and outflows.  In this talk, I will show some of the first results
from the CUBS program.
