Galaxies probing galaxies in PRIMUS. I.
The spectroscopy of background QSO sightlines passing close to foreground galaxies is a potent technique for studying the circumgalactic medium (CGM). However, QSOs are... -
Ly{alpha} forest power spectrum at 1.8<=z<=3.4
We present a new measurement of the Ly{alpha} forest power spectrum at 1.8<z<3.4 using 74 Keck/HIRES and VLT/UVES high-resolution, high-signal-to-noise-ratio quasar... -
HeII photoionization rates of quasars
The HeII transverse proximity effect-enhanced HeII Ly{alpha} transmission in a background sightline caused by the ionizing radiation of a foreground quasar-offers a unique... -
LAE candidates around bright Ly{alpha} blobs
Bright Ly{alpha} blobs (LABs)-extended nebulae with sizes of ~100kpc and Ly{alpha} luminosities of ~10^44^erg/s -- often reside in overdensities of compact Ly{alpha} emitters... -
The SSA22 HI tomography survey. I. Redshifts
We conducted a deep spectroscopic survey, named SSA22-HIT, in the SSA22 field with the DEep Imaging MultiObject Spectrograph (DEIMOS) on the Keck telescope, designed to... -
Objects within 10arcmin of AGN from NED
Most baryonic matter in the universe exists in gaseous form and can be found in structures such as galactic halos and the low-density intergalactic medium. Proposed X-ray... -
KODIAQ DR3: 727 quasars (0.1<zem<6.4) with ESI
We present and make publicly available the third data release (DR3) of the Keck Observatory Database of Ionized Absorption toward Quasars (KODIAQ) survey. KODIAQ DR3 consists of... -
Intergalac. medium opacity from Lyman-break galaxies
We measure the effective opacity ({tau}eff) of the intergalactic medium from the composite spectra of 281 Lyman-break galaxies in the redshift range 2<~z<~3. Our spectra... -
Ions density in the CGM of low mass galaxy groups
We explore how environment affects the metallicity of the circumgalactic medium (CGM) using 13 low-mass galaxy groups (two to five galaxies) at =0.25 identified near background... -
AMUSING++ nearby galaxy compilation. I. Sample
We present here the All-weather MUse Supernova Integral-field of Nearby Galaxies (AMUSING++): the largest compilation of nearby galaxies observed with the Multi Unit... -
Total ALFALFA H I fluxes for extended sources
A procedure is presented to improve on measurement of total H I fluxes for extended sources in the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey of neutral... -
LAE cand. at z~5.7 in the field of QSO J0148+0600
The observed scatter in intergalactic Ly{alpha} opacity at z<~6 requires large-scale fluctuations in the neutral fraction of the intergalactic medium (IGM) after the expected... -
Abundances in inner, outer & FOV of 18 clusters
The intracluster medium (ICM) is a reservoir of heavy elements synthesized by different supernovae (SNe) types over cosmic history. Different enrichment mechanisms contribute a... -
CGM-MASS. II. New XMM data for 6 spirals
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.... -
Chandra obs. of low-metallicity star-forming gal.
High-energy emission associated with star formation has been proposed as a significant source of interstellar medium (ISM) ionization in low-metallicity starbursts and an... -
Chandra obs. of Planck ESZ & X-ray clusters
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... -
Gas content of the dwarf gal. within 2Mpc of the MW
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...
