Caught in the act: diffuse stellar and Ly emission around a halo-less quasar in the assembling cluster CARLA J0800+4029 at z=2
Sofia G. Gallego, Simona Mei, Emanuele Daddi +3
Extended Ly emission is commonly detected around luminous quasars at -3 and traces cold gas in the circumgalactic environment of the AGN. Together with the spatial distr…
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…
Characterizing the Circumgalactic Medium of Quasars at z 2.2 through H and Ly Emission
Vivienne Langen, Sebastiano Cantalupo, Charles C. Steidel +3
The discovery of giant quasar Ly nebulae at has opened up the possibility to directly study in emission the Circumgalactic and Intergalactic Medium (CGM/IGM). However, the…
The MUSE eXtremely Deep Field: Individual detections of Lyα haloes around rest-frame UV-selected galaxies at z~2.9-4.4
Haruka Kusakabe, Anne Verhamme, Jeremy Blaizot +15
Hydrogen Ly haloes (LAHs) are commonly used as a tracer of the circumgalactic medium (CGM) at high redshifts. In this work, we aim to explore the existence of Ly haloes aroun…
