The Synthetic Absorption Line Spectral Almanac (SALSA)
Dylan Nelson, Celine Peroux, Philipp Richter +10
We create the first large-scale mock spectroscopic survey of gas absorption sightlines traversing the interstellar medium (ISM), circumgalactic medium (CGM), and intergalactic medi…
High-S/N Quasar Observations with HST/COS: Deep Fields for Spectroscopy
Andrew J. Fox, Jerry Kriss, Philipp Richter +49
Hubble is still in prime observing condition for making transformative discoveries in UV astronomy. In this white paper we describe the science case for a deep (S/N>30) UV spectros…
Spatial-Kinematic Absorption Models of the Circumgalactic Medium. I. Structures, Orientations, and Kinematics
Christopher W. Churchill
In this two-paper series, we present a straightforward mathematical model for synthesizing quasar absorption line profiles from sight lines through idealized, spatial-kinematic mod…
Spatial-Kinematic Absorption Models of the Circumgalactic Medium. II. Ionized Gas Phases and Absorption Lines
Christopher W. Churchill
In this two-paper series, we present a straightforward mathematical model for synthesizing quasar absorption line profiles from sight lines through idealized, spatial-kinematic mod…
13 Billion Years of MgII Absorber Evolution
Christopher W. Churchill, Asif Abbas, Glenn G. Kacprzak +1
Applying "apportioned integrals," we use dN/dX measurements to determine the MgII absorber equivalent width distribution function for Wr > 0.03 [angstroms] and 0 < z < 7. Adopting…
