Paper Abstract

CETUS (“Cosmic Evolution Through Ultraviolet Spectroscopy”) is a mission concept that was selected by NASA for study as a Probe-class mission, meaning a mission whose full life-cycle cost to NASA is between $400M and $1.0B. CETUS has a wide-field UV telescope that will work with other survey telescopes observing at gamma-rays to radio waves to help solve major problems in galaxy and stellar astrophysics. CETUS features a 1.5-m telescope and two widefield survey instruments, a near-UV multi-object slit spectrograph (MOS), a near-UV/ far-UV camera. It also has a near- UV/far-UV imaging spectrograph to survey classes of astronomical objects one at a time. In this paper, we describe how CETUS will address questions posed by the 2010 Astrophysics Decadal Survey panel (Astro-2010) including: what are the drivers of galaxy evolution at the peak rate of star formation; what are the path(s) of evolution from the blue cloud to the red sequence; and how does the circumgalactic medium influence galaxy evolution and vice versa.
