MUSE Analysis of Gas around Galaxies (MAGG) -- VII. Emission line galaxies near strong blended Ly absorption systems at
Marta Galbiati, Davide Tornotti, Michele Fumagalli +2
We investigate the connection between strong, blended Ly absorption systems (SBLAs) and Ly emitting galaxies (LAEs) at in 28 quasar fields from th…
The MUSE Ultra Deep Field (MUDF) VIII. The cool gas distribution surrounding galaxies at redshifts z ~ 0.5-2
Edoardo Santo, Michele Fumagalli, Seok-Jun Chang +5
We use deep MUSE data from the MUDF survey to investigate the cool gas around galaxies at redshifts 0.5 < z < 2. We constructed two samples: one sample for a down-the-barrel analys…
Bayesian luminosity function estimation in multi-depth datasets with selection effects: A case study for Lyman emitters
Davide Tornotti, Matteo Fossati, Michele Fumagalli +3
We present a hierarchical Bayesian framework designed to infer the luminosity function of any class of object by jointly modelling data from multiple surveys with varying depth, co…
Baryonic Ecosystem IN Galaxies (BEINGMgII) -- III. Cool gas reservoirs at in the Dark Energy Survey
Reena Chaudhary, Ravi Joshi, Sarbeswar Das +5
We investigate the origin of intervening cool MgII absorption detected in the spectra of background quasars and the nature of associated galaxies across a broad redshift range of $…
Automated quasar continuum estimation using neural networks: a comparative study of deep-learning architectures
Francesco Pistis, Michele Fumagalli, Matteo Fossati +13
Context. Ongoing and upcoming large spectroscopic surveys are drastically increasing the number of observed quasar spectra, requiring the development of fast and accurate automated…
The MUSE Ultra Deep Field: A 5 Mpc stretch of the z 4 cosmic web revealed in emission
Davide Tornotti, Michele Fumagalli, Matteo Fossati +7
We detect Ly emission from a ~5 Mpc-long (comoving) portion of the cosmic web hosting an overdensity () of 19 Ly emitters (LAEs) at within the MU…
