Hydra I cluster study with H I emission
We present results from our analysis of the Hydra I cluster observed in neutral atomic hydrogen (H I) as part of the Widefield ASKAP L-band Legacy All-sky Blind Survey... -
Thermal parameters of the IGM at 2 <= z <= 4
We characterize the thermal state of the intergalactic medium (IGM) in 10 redshift bins in the range 2 <= z <= 4 with a sample of 103 high-resolution, high S/N Ly{alpha}... -
Lyman limit systems in large quasar surveys
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... -
Quasar Sightline and Galaxy Evolution Survey I
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... -
HI enhancement in proto-cluster
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... -
Void catalogs from SDSS DR7
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... -
CLAMATO DR2 redshift catalog
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... -
Damped Ly{alpha} systems from SDSS DR16Q
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... -
CLAMATO DR1: 3D Ly{alpha} forest tomography
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... -
Gal. redshift survey near HST/COS AGN sight lines
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... -
2<zobs<4 quasars stacked spectrum
We investigate the metal species associated with the Ly{alpha} forest in eBOSS quasar spectra. Metal absorption lines are revealed in stacked spectra from cross-correlating the... -
CGM2 galaxy-OVI absorber pairs
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... -
Compilation of double radio sources
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... -
Milky Way SiIV and CIV kinematics from HST/COS
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... -
Galaxy-absorber pairs for low-z QSO sightlines
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... -
VLT/X-SHOOTER & Keck/ESI spectra of z~5 QSOs
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... -
18 UV bright QSOs obs. with HST (COS-IGrM survey)
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... -
Ly{alpha} emitters and QSOs in COMSOS and EGS fields
We present cosmological (30-400Mpc) distributions of neutral hydrogen (HI) in the intergalactic medium (IGM) traced by Ly{alpha} emitters (LAEs) and QSOs at z=2.1-2.5, selected... -
Foreground galaxies toward FRB 190608 from SDSS
Fast radio burst (FRB) 190608 was detected by the Australian Square Kilometre Array Pathfinder (ASKAP) and localized to a spiral galaxy at z_host_=0.11778 in the Sloan Digital... -
Ghostly damped Ly{alpha} systems in SDSS DR14
We report the discovery of 59 new ghostly absorbers from the Sloan Digital Sky Survey Data Release 14. These absorbers, with z_abs_~z_QSO_, reveal no Ly{alpha} absorption, and...
