Modeling Mg II resonance doublet spectra from galaxy haloes at z 1
Seok-Jun Chang, Rajeshwari Dutta, Max Gronke +3
We investigate the properties of cold gas at around star-forming galaxies at using Mg II spectra through radiative transfer modeling. We utilize a comprehen…
Baryonic Ecosystem in Galaxies (BEINGMgII). Host Galaxies of Ultra-strong MgII Absorbers in Subaru Hyper Suprime-Cam Survey
Ravi Joshi, Sarbeswar Das, Michele Fumagalli +5
We study the galaxies hosting ultra-strong MgII (USMgII) absorbers at small impact parameters of 2" (5 - 20 kpc), spanning a redshift range of , using deep…
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 MUSE…
WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet
M. I. Arnaudova, S. Das, D. J. B. Smith +62
We present a detailed study of the large-scale shock front in Stephan's Quintet, a byproduct of past and ongoing interactions. Using integral-field spectroscopy from the new Willia…
The MUSE Ultra Deep Field (MUDF) VII. Probing high-redshift gas structures in the surroundings of ALMA-identified massive dusty galaxies
A. Pensabene, M. Galbiati, M. Fumagalli +12
We present new ALMA continuum and spectral observations of the MUSE Ultra Deep Field (MUDF), a arcmin region with ultradeep multiwavelength imaging and spectroscopy…
X-ray view of a massive node of the Cosmic Web at z~3 I. An exceptional overdensity of rapidly accreting SMBHs
A. Travascio, S. Cantalupo, P. Tozzi +16
Exploring SMBH population in protoclusters offers valuable insights into how environment affects SMBH growth. However, research on AGN within these areas is still limited by the sm…
Baryonic Ecosystem in Galaxies (BEINGMgII) -- II. Unveiling the Nature of Galaxies Harboring Cool Gas Reservoirs
S. Das, R. Joshi, R. Chaudhary +4
We search for the galaxies associated with the intervening MgII absorbers over a redshift range of using imaging data from DESI Legacy Imaging Surveys and measu…
Connecting the growth of galaxies to the large-scale environment in a massive node of the Cosmic Web at z~3
M. Galbiati, S. Cantalupo, C. Steidel +10
A direct link between large-scale environment and galaxy properties is very well established in the local universe. However, very little is known about the role of the environment…
A Giant Disk Galaxy Two Billion Years After The Big Bang
Weichen Wang, Sebastiano Cantalupo, Antonio Pensabene +14
Observational studies showed that galaxy disks are already in place in the first few billion years of the universe. The early disks detected so far, with typical half-light radii o…
Metal line emission around z<1 galaxies
Rajeshwari Dutta, Michele Fumagalli, Matteo Fossati +7
We characterize, for the first time, the average extended emission in multiple lines ([OII], [OIII], and Hbeta) around a statistical sample of 560 galaxies at z~0.25-0.85. By stack…
The stellar population of a Ly emitting group associated with a damped Ly absorber
Giulia Pruto, Michele Fumagalli, Marc Rafelski +4
We present near-infrared observations, acquired with the Wide Field Camera 3 (WFC3) on board of the Hubble Space Telescope (HST), of a Ly double-clumped emitting nebula at $z \a…
The MUSE Ultra Deep Field (MUDF). VI. The relationship between galaxy properties and metals in the circumgalactic medium
Alexander Beckett, Marc Rafelski, Mitchell Revalski +10
We present intial results associating galaxies in the MUSE Ultra Deep Field (MUDF) with gas seen in absorption along the line-of-sight to two bright quasars in this field, to explo…
MUSE Analysis of Gas around Galaxies (MAGG) -- VI. The cool and enriched gas environment of z3 Ly emitters

We present a novel dataset that extends our view of the cosmic gas around z3-4 Ly emitting galaxies (LAEs) in the Muse Analysis of Gas around Galaxies (MAGG) survey by…
High-definition imaging of a filamentary connection between a close quasar pair at z=3
Davide Tornotti, Michele Fumagalli, Matteo Fossati +16
Filaments connecting halos are a long-standing prediction of cold dark matter theories. We present a detection of the cosmic web emission connecting two quasar-host galaxies at red…
