MUSE Analysis of Gas around Galaxies (MAGG) -- I: Survey design and the environment of a near pristine gas cloud at z~3.5
Emma K. Lofthouse, Michele Fumagalli, Matteo Fossati +9
We present the design, methods, and first results of the MUSE Analysis of Gas around Galaxies (MAGG) survey, a large programme on the Multi Unit Spectroscopic Explorer (MUSE) instr…
Gas filaments of the cosmic web located around active galaxies in a proto-cluster
H. Umehata, M. Fumagalli, I. Smail +15
Cosmological simulations predict the Universe contains a network of intergalactic gas filaments, within which galaxies form and evolve. However, the faintness of any emission from…
MUSEQuBES: Calibrating the redshifts of Ly α emitters using stacked circumgalactic medium absorption profiles
Sowgat Muzahid, Joop Schaye, Raffaella Anna Marino +17
Lyman (Ly) emission lines are typically found to be redshifted with respect to the systemic redshifts of galaxies, likely due to resonant scattering of Ly photons. Here w…
3D Distribution Map of HI Gas and Galaxies Around an Enormous Ly Nebula and Three QSOs at Revealed by the HI Tomographic Mapping Technique
Shiro Mukae, Masami Ouchi, Zheng Cai +21
We present an IGM HI tomography map in a survey volume of (cMpc) centered at MAMMOTH-1 nebula and three neighbouring…
Evolution of the Cool Gas in the Circumgalactic Medium (CGM) of Massive Halos -- A Keck Cosmic Web Imager (KCWI) Survey of Ly Emission around QSOs at
Zheng Cai, Sebastiano Cantalupo, J. Xavier Prochaska +6
Motivated by the recent discovery of the near-ubiquity of Ly emission around QSOs, we performed a systematic study of QSO circumgalactic Ly emission at $z\appro…
The MUSE Ultra Deep Field (MUDF). II. Survey design and the gaseous properties of galaxy groups at 0.5 < z < 1.5
M. Fossati, M. Fumagalli, E. K. Lofthouse +12
We present the goals, design, and first results of the MUSE Ultra Deep Field (MUDF) survey, a large programme using the Multi Unit Spectroscopic Explorer (MUSE) instrument at the E…
