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…
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…
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…
The Small-scale Structures in the Wind of Messier 82
Yucheng Guo, Timothy Heckman, Sanchayeeta Borthakur +10
Small-scale multiphase structure plays a central role in galactic-wind evolution, yet the parsec-scale morphology and excitation of the warm ionised gas remain poorly constrained.…
LCEz4-M1: A Lyman Continuum Emitter Candidate at z = 4.444 in the MUSE Hubble Ultra Deep Field
Shuairu Zhu, Zhen-Ya Zheng, Fuyan Bian +5
High-redshift Lyman continuum emitters (LCEs) are crucial for understanding how galaxies ionize the neutral hydrogen in the epoch of reionization. However, detected LCEs at a…
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,…
