Ly-alpha emission reveals two satellite halos around massive groups at z ~ 3: the puzzling case of a quiescent central galaxy
Sicen Guo, Emanuele Daddi, Raphael Gobat +17
We present the discovery and characterisation of two Ly nebulae (LANs), RO-1001-Sat and RO-0959-Sat, as satellite structures of two giant LANs at and 3.092. They are f…
Coevolution of halo and quasar properties in dense environments: CARLA J1017+6116 at z=2.8
Sofia G. Gallego, Simona Mei, Christopher Martin +4
Radio-loud active galactic nuclei, in particular radio-loud quasars, are fueled by accretion onto supermassive black holes and are among the most energetic sources in the Universe.…
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…
Constraining the cosmic UV background at z>3 with MUSE Lyman-α emission observations
Sofia G. Gallego, Sebastiano Cantalupo, Saeed Sarpas +10
The intensity of the Cosmic UV background (UVB), coming from all sources of ionising photons such as star-forming galaxies and quasars, determines the thermal evolution and ionizat…
A giant Ly nebula and a small-scale clumpy outflow in the system of the exotic quasar J0952+0114 unveiled by MUSE
R. A. Marino, S. Cantalupo, G. Pezzulli +11
The well-known quasar SDSS J095253.83+011421.9 (J0952+0114) at z=3.02 has one of the most peculiar spectra discovered so far, showing the presence of narrow Ly and broad metal e…
The large and small scale properties of the intergalactic gas in the Slug Ly-alpha nebula revealed by MUSE HeII emission observations
Sebastiano Cantalupo, Gabriele Pezzulli, Simon J. Lilly +11
With a projected size of about 450 kpc at z~2.3, the Slug Ly-alpha nebula is a rare laboratory to study, in emission, the properties of the intergalactic gas in the Cosmic Web. Sin…
