We present a pipeline based on a random forest classifier for the identification of high column density clouds of neutral hydrogen (i.e. the Lyman limit systems, LLSs) in...

We present the first results from a study of OVI absorption around galaxies at z<1.44 using data from a near-infrared grism spectroscopic Hubble Space Telescope Large...

In the SSA22 field which exhibits a large-scale proto-cluster at z=3.1, we carried out a spectroscopic survey for Lyman Break Galaxies (LBGs) with the VLT/VIMOS and identified...

We produce several public void catalogs using a volume-limited subsample of the Sloan Digital Sky Survey Data Release 7 (SDSS DR7). Using new implementations of three different...

We present the second data release of the COSMOS Ly{alpha} Mapping And Tomography Observations Survey conducted with the Low Resolution Imaging Spectrometer on the Keck I...

The intracluster medium (ICM) is a reservoir of heavy elements synthesized by different supernovae (SNe) types over cosmic history. Different enrichment mechanisms contribute a...

We present the characteristics of the damped Ly{alpha} (DLA) systems found in data release DR16 of the extended Baryon Oscillation Spectroscopic Survey of the Sloan Digital Sky...

Faint star-forming galaxies at z~2-3 can be used as alternative background sources to probe the Ly{alpha} forest in addition to quasars, yielding high sightline densities that...

To establish the connection between galaxies and UV-detected absorption systems in the local universe, a deep (g<=20) and wide (~20' radius) galaxy redshift survey is...

We present the analysis of the XMM-Newton data of the Circum-Galactic Medium of MASsive Spirals (CGM-MASS) sample of six extremely massive spiral galaxies in the local universe....

We combine 126 new galaxy-OVI absorber pairs from the CGM^2^ survey with 123 pairs drawn from the literature to examine the simultaneous dependence of the column density of OVI...

The origin of magnetic fields in clusters of galaxies is still a matter of debate. Observations for intracluster magnetic fields over a wide range of redshifts are crucial to...

We compose a 265-sight-line Milky Way CIV line-shape sample using the Hubble Space Telescope/Cosmic Origins Spectrograph archive, which is complementary to the existing SiIV...

We present a study of candidate galaxy-absorber pairs for 43 low-redshift QSO sightlines (0.06<z<0.85) observed with the Hubble Space Telescope/Cosmic Origins Spectrograph...

We present a new investigation of the intergalactic medium (IGM) near the end of reionization using "dark gaps" in the Ly{alpha} forest. Using spectra of 55 QSOs at...

We present the results of the Cosmic Origins Spectrograph-Intragroup Medium (COS-IGrM) Survey that used the COS on the Hubble Space Telescope to observe a sample of 18 UV bright...

The dynamical evolution and radiative properties of luminous radio galaxies and quasars of the FR II type, are well understood. As a result, through the use of detailed modeling...

This study uses HI image data from the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) pilot survey with the Australian Square Kilometre Array Pathfinder (ASKAP)...

Using Chandra observations, we derive the YX proxy and associated total mass measurement, M_500_^Yx^ for 147 clusters with z<0.35 from the Planck early Sunyaev-Zeldovich...

The gas content of the complete compilation of Local Group dwarf galaxies (119 within 2Mpc) is presented using HI survey data. Within the virial radius of the Milky Way (224kpc...
