A First Measurement of Circumgalactic Dust Reddening from Only 4.6 deg of the Rubin Observatory's DP1
John Franklin Crenshaw, Matthew McQuinn, Jessica K. Werk
We present the first measurement of circumgalactic dust reddening from the Vera C. Rubin Observatory, using only 4.6 deg of ComCam Data Preview 1 - roughly of the fina…
Revealing Cosmic Ecosystems with the Hubble Space Telescope in 2030s and Beyond
Sanchayeeta Borthakur, Tanmay Singh, David French +22
Ultraviolet spectroscopy with the Hubble Space Telescope (HST) provides the most direct and sensitive probe of the disk-circumgalactic medium (CGM) interface at radii of 20 kpc, wh…
A Decade to Map the Diffuse Universe: FRB-QSO Pairs with HST/COS Spectroscopy
Jessica Werk, Matthew McQuinn, J. Xavier Prochaska +16
Jointly analyzing the sightlines of arcsecond-localized fast radio bursts (FRBs) and UV-bright quasars (QSOs) nearby in projection has the potential to provide strong constraints o…
Astronomical Advantages of a Boost Mission to Facilitate HST Science into the 2030s: Imaging the Circumgalactic Medium of Galaxies
Matthew J. Hayes, Kate H. R. Rubin, Michelle A. Berg +20
We present the case for imaging ultraviolet line emission from highly ionized metals and HI Lya in the circumgalactic medium of galaxies, should the Hubble Space Telescope receive…
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…
Mainly on the Plane: Observing the Extended, Ionized Disks of Milky Way Analogs in IllustrisTNG
Michael Messere, Kirill Tchernyshyov, Mary E. Putman +4
This paper explores the extent to which the circumgalactic medium (CGM) of Milky Way-like galaxies is located in an extended, ionized, disklike structure. To test this hypothesis,…
