Link between the properties of circumgalactic outflows and the recent star formation history of their host galaxies

Ismael Pessa, Lutz Wisotzki, Constanza Muñoz López +8

Galactic outflows play a key role in galaxy evolution, yet their connection to the star formation history of their host galaxies remains poorly constrained. Building on previous wo…

MUSE-ALMA Haloes XVI: a census of the condensed baryons in z~0.5 HI absorption-selected galaxies

T. O'Beirne, C. Péroux, M. Zwaan +16

We use the MUSE-ALMA Haloes sample to build a census of the condensed baryons (stars and cold gas) to study the multiphase interstellar medium and circumgalactic medium (CGM). The…

MUSE-ALMA Haloes XV: Cold molecular, ionised, and stellar kinematics of HI-rich galaxies at z 0.5

C. Barfety, N. M. Förster Schreiber, C. Péroux +13

Spatially resolved galaxy kinematics are well studied at z 0 and z > 1, revealing that disks are common out to z , albeit with higher velocity dispersions. z …

MUSE-ALMA Haloes XIV: The ALMA Large Programme Data Release

Céline Péroux, Jianhang Chen, Victoria Bollo +10

The interactions between gas and galaxies are of paramount importance to our understanding of structure formation. A fundamental element of such baryon cycle studies is a complete…

Two domains of extended Lyman-alpha emission around galaxies: from local radiation to environmental regulation

Daria Kozlova, Lutz Wisotzki, John Pharo +7

We examine the relation between extended Ly halos around high-redshift galaxies and the main factors responsible for driving the emission in such halos, in particular at distanc…

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 redshifts…

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…

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: Probing Anisotropies in Gas and Metal Distributions in the Circumgalactic Medium

Sayak Dutta, Sowgat Muzahid, Joop Schaye +9

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…
