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…
Constraining Sub-Parsec Binary Supermassive Black Holes in Quasars with Multi-Epoch Spectroscopy. III. Candidates from Continued Radial Velocity Tests
Hengxiao Guo, Xin Liu, Yue Shen +3
Quasars whose broad emission lines show temporal, bulk radial velocity (RV) shifts have been proposed as candidate sub-parsec (sub-pc), binary supermassive black holes (BSBHs). We…
Overdensity of submillimeter galaxies around the MAMMOTH-1 nebula
F. Arrigoni Battaia, Chian-Chou Chen, M. Fumagalli +7
In the hierarchical model of structure formation, giant elliptical galaxies form through merging processes within the highest density peaks known as protoclusters. While high-redsh…
Imprints of the first billion years: Lyman limit systems at
Neil H. M. Crighton, J. Xavier Prochaska, Michael T. Murphy +3
Lyman Limit systems (LLSs) trace the low-density circumgalactic medium and the most dense regions of the intergalactic medium, so their number density and evolution at high redshif…
The COS Absorption Survey of Baryon Harbors (CASBaH): Warm-hot Circumgalactic Gas Reservoirs Traced by Ne VIII Absorption
Joseph N. Burchett, Todd M. Tripp, J. Xavier Prochaska +13
We survey the highly ionized circumgalactic media (CGM) of 29 blindly selected galaxies at 0.49 < z_(gal) < 1.44 based on high-S/N ultraviolet spectra of z > 1 QSOs and the galaxy…
Extreme circumgalactic HI and CIII absorption around the most massive, quenched galaxies
Marijana Smailagić, Jason Xavier Prochaska, Joseph Burchett +2
Luminous red galaxies (LRGs) are the most massive galaxies at and, by selection, have negligible star formation. These objects have halo masses between those of …
