Lyman-alpha haloes in the aftermath of reionisation
Daniil Smirnov, Lutz Wisotzki, Tanya Urrutia +8
We present a comparative study of Ly haloes (LAHs) around low-luminosity (L erg s) Ly-emitting galaxies (LAEs) at very high redshif…
MusE GAs FLOw and Wind (MEGAFLOW) XIV: Background-Galaxy Absorption Reveals Kiloparsec-Scale Structure in the Cool Circumgalactic Medium
Yucheng Guo, Nicolas F. Bouché, Martin Wendt +9
The properties of the cool (~K) gas in the circumgalactic medium (CGM) are closely linked to the physical mechanisms that create and maintain this multiphase medium. The…
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…
MUSEQuBES: Probing Anisotropies in Gas and Metal Distributions in the Circumgalactic Medium
Sayak Dutta, Sowgat Muzahid, Joop Schaye +10
We investigate the azimuthal dependence of HI and OVI-bearing gas in the circumgalactic medium (CGM) of 113 isolated galaxies in the redshift range , including 91 new…
First statistical constraints on galactic scale outflows properties traced by their extended Mg II emission with MUSE
Ismael Pessa, Lutz Wisotzki, Tanya Urrutia +7
Galaxies evolve within vast gaseous halos that fuel star formation and carry signatures of feedback-driven outflows. Deep integral field data have enabled the study of MgII halos,…
MUSEQuBES: The Column Density, Covering Fraction, Mass, and Environmental Dependence of Cool HI Gas Around Low-Redshift Galaxies
Sayak Dutta, Sowgat Muzahid, Joop Schaye +6
We investigate cool HI gas traced by Lyman series absorption around 256 galaxies at z ~ 0.48 (median stellar mass, log10(M*/Msun) = 8.7) using 15 background quasars (median impact…
