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…
Galaxy Formation and Symbiotic Evolution with the Inter-Galactic Medium in the Age of ELT-ANDES
Valentina D'Odorico, James S. Bolton, Lise Christensen +21
High-resolution absorption spectroscopy toward bright background sources has had a paramount role in understanding early galaxy formation, the evolution of the intergalactic medium…
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 \…
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…
