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…
MusE GAs FLOw and Wind (MEGAFLOW) X. The cool gas and covering fraction of MgII in galaxy groups
Maxime Cherrey, Nicolas Bouché, Johannes Zabl +8
We present a study of the cool gas ( K) traced by MgII absorptions around groups of galaxies in the MEGAFLOW survey. Using a combination of two algorithms we blindly…
MAGIC: Muse gAlaxy Groups In Cosmos -- A survey to probe the impact of environment on galaxy evolution over the last 8 Gyr
B. Epinat, T. Contini, W. Mercier +22
We introduce the MUSE gAlaxy Groups in COSMOS (MAGIC) survey, which was built to study the impact of environment on galaxy evolution over the last 8 Gyr. It consists of 17 MUSE fie…
The MUSE-Faint survey. III. Constraining scalar field dark matter with Antlia B
Mariana P. Júlio, Jarle Brinchmann, Sebastiaan L. Zoutendijk +7
Aims. We use the stellar line-of-sight velocities of Antlia B (Ant B), a faint dwarf galaxy in the NGC 3109 association, to derive constraints on the fundamental properties of scal…
Large-scale excess HI absorption around galaxies detected in a background galaxy spectrum in the MUSE eXtremely Deep Field
Jorryt Matthee, Christopher Golling, Ruari Mackenzie +12
Observationally mapping the relation between galaxies and the intergalactic medium (IGM) is of key interest for studies of cosmic reionization. Diffuse hydrogen gas has typically b…
EMPRESS. XII. Statistics on the Dynamics and Gas Mass Fraction of Extremely-Metal Poor Galaxies
Yi Xu, Masami Ouchi, Yuki Isobe +49
We present demography of the dynamics and gas-mass fraction of 33 extremely metal-poor galaxies (EMPGs) with metallicities of and low stellar masses of $10^4-…
