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…
An SDSS-V 3D Tomographic Na I Map of the ISM: An Initial Study Towards the Smith Cloud
Timothy McQuaid, Joseph N. Burchett, Kate H. R. Rubin +7
High velocity clouds supply the Milky Way with gas that sustains star formation over cosmic timescales. Precise distance measurements are therefore essential to quantify their mass…
Low Metallicity Gas on the Outskirts of the Local Group: the Circumgalactic Medium of Sextans B
Andrew J. Fox, Sapna Mishra, Frances H. Cashman +6
We present a UV absorption-line analysis of the circumgalactic medium (CGM) of Sextans B, a dwarf irregular galaxy at 1.3 Mpc distance on the outer frontier of the Local Group. Usi…
