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.…
Circumgalactic Ly Nebulae in Overdense Quasar Pair Regions Observed with the Palomar Cosmic Web Imager
Jessica S. Li, Carlos J. Vargas, Donal O'Sullivan +8
The recent discovery of enormous Ly nebulae (ELANe), characterized by physical extents kpc and Ly luminosities erg s, provide a unique opportunity to…
Three Lyman-alpha emitting filaments converging to a massive galaxy group at z=2.91: discussing the case for cold gas infall
E. Daddi, F. Valentino, R. M. Rich +21
We have discovered a 300kpc-wide giant Lya nebula centered on the massive galaxy group RO-1001 at z=2.91 in the COSMOS field. Keck Cosmic Web Imager observations reveal three cold…
Spectroscopic Confirmation of a Coma Cluster Progenitor at z ~ 2.2
Behnam Darvish, Nick Z. Scoville, Christopher Martin +17
We report the spectroscopic confirmation of a new protocluster in the COSMOS field at 2.2, COSMOS Cluster 2.2 (CC2.2), originally identified as an overdensity of narrowb…
The FLASHES Survey I: Integral Field Spectroscopy of the CGM around 48 QSOs
Donal O'Sullivan, Christopher Martin, Mateusz Matuszewski +5
We present the pilot study component of the Fluorescent Lyman-Alpha Structures in High-z Environments (FLASHES) Survey; the largest integral-field spectroscopy survey to date of th…
Multi-Filament Inflows Fueling Young Star Forming Galaxies
D. Christopher Martin, Donal O'Sullivan, Mateusz Matuszweski +13
Theory suggests that there are two primary modes of accretion through which dark matter halos acquire the gas to form and fuel galaxies, hot and cold mode accretion. In cold mode a…
Keck/Palomar Cosmic Web Imagers (KCWI/PCWI) Reveal an Enormous Ly Nebula in an Extremely Overdense QSO Pair Field at
Zheng Cai, Erika Hamden, Matt Matuszewski +10
Enormous Ly nebulae (ELANe) represent the extrema of Ly nebulosities. They have detected extents of kpc in Ly and Ly luminosities erg s. The EL…
