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…
A galactic outflow traced by its extended Mg II emission out to a kpc radius in the Hubble Ultra Deep Field with MUSE
Ismael Pessa, Lutz Wisotzki, Tanya Urrutia +12
We report the discovery of a rare Mg II 2796, 2803 doublet emission halo around a star forming galaxy with /M at in deep (9.…
The Intrinsic Distribution of Lyman- Halos
John Pharo, Lutz Wisotzki, Tanya Urrutia +10
The emission and escape of Lyman- photons from star-forming galaxies is determined through complex interactions between the emitted photons and a galaxy's interstellar and circu…
