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 is a wide-field UV telescope that will work with other survey telescopes observing at gamma-rays to radio waves to help solve major astrophysical problems. In this paper, we describe how CETUS will make observations of high-energy sources discussed by the 2010 Astrophysics Decadal Survey panel (Astro-2010) including the growth of nuclear black holes and their influence on their surroundings, mergers of neutron-star binaries and their aftermath, supernovae and their progenitors, the flows of matter and energy in the circumgalactic medium. CETUS is well equipped to study these energetic sources. We have chosen instrumentation for CETUS that includes a 1.5-m telescope and two wide-field 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.
