  • Catalog of galaxies in and around A1367

    We present a catalog of galaxies in and around the cluster A1367, together with the results of a spectroscopic study of eight faint galaxies projected onto the central part of...
  • Powerful radio sources in the Southern Sky. I.

    Since the early sixties, our view of radio galaxies and quasars has been drastically shaped by discoveries made thanks to observations of radio sources listed in the Third...
  • Jet kinematics of blazars at 43GHz with 10yrs obs.

    We analyze the parsec-scale jet kinematics from 2007 June to 2018 December of a sample of {gamma}-ray bright blazars monitored roughly monthly with the Very Long Baseline Array...
  • Predicted redshifts for 4FGL gamma-ray loud AGNs

    Measuring the redshift of active galactic nuclei (AGNs) requires the use of time-consuming and expensive spectroscopic analysis. However, obtaining redshift measurements of AGNs...
  • IDEOS. II. Observables in the 5.4-36{mu}m range

    We present the Infrared Database of Extragalactic Observables from Spitzer (IDEOS), a homogeneous, publicly available, database of 77 fitted mid-infrared observables in the...
  • Head-tail radio galaxies from the VLA FIRST survey

    The head-tail (HT) morphology of radio galaxies is seen for a class of radio sources where the primary lobes are being bent in the intercluster weather due to strong...
  • DES Bright Arcs Survey: strong lens systems

    We report the combined results of eight searches for strong gravitational lens systems in the full 5000 square degrees of Dark Energy Survey (DES) observations. The observations...
  • GOLDRUSH. IV. z~3-7 galaxies

    We present new measurements of rest-UV luminosity functions and angular correlation functions from 4,100,221 galaxies at z~2-7 identified in the Subaru/Hyper Suprime-Cam survey...
  • SHELLQs. XVI. New quasars at 5.8<z<7

    We present the spectroscopic discovery of 69 quasars at 5.8<z<7.0, drawn from the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) imaging survey data. This is the...
  • Stellar population parameters from LAMOST DR7

    We first derive the stellar population properties: age and metallicity for ~43000 low redshift galaxies in the DR7 of the Large Sky Area Multi-Object Fiber Spectroscopic...
  • Iron template spectrum from Mrk493 HST/STIS obs.

    We present a new empirical template for iron emission in active galactic nuclei (AGNs) covering the 4000-5600{AA} range. The new template is based on a spectrum of the...
  • Opt. & UV cat. of Abell 1882 galaxy members

    A rare opportunity to distinguish between internal and environmental effects on galaxy evolution is afforded by "SuperGroups," systems that are rich and massive, but include...
  • Southern-sky optical AGN catalog from 6dFGS sp.

    We have constructed a catalog of active galactic nuclei (AGNs) with z<0.13, based on optical spectroscopy, from the parent sample of galaxies in the Six-Degree Field (6dF)...
  • CDWFS: Chandra survey in Bootes. I. X-ray cat.

    We present a new, ambitious survey performed with the Chandra X-ray Observatory of the 9.3deg^2^ Bootes field of the NOAO Deep Wide-Field Survey. The wide field probes a...
  • Strong DES lens candidates from neural networks

    We search Dark Energy Survey (DES) Year 3 imaging for galaxy-galaxy strong gravitational lenses using convolutional neural networks, extending previous work with new training...
  • The Chandra UDS survey (X-UDS)

    We present the X-UDS survey, a set of wide and deep Chandra observations of the Subaru-XMM Deep/UKIDSS Ultra Deep Survey (SXDS/UDS) field. The survey consists of 25 observations...
  • NuSTAR Extragalactic Surveys: UDS field

    We present the results and the source catalog of the NuSTAR survey in the UKIDSS Ultra Deep Survey (UDS) field, bridging the gap in depth and area between NuSTAR's ECDFS and...
  • CANDELS: multiwavelength catalogs in the EGS

    We present a 0.4-8{mu}m multi-wavelength photometric catalog in the Extended Groth Strip (EGS) field. This catalog is built on the Hubble Space Telescope (HST) WFC3 and ACS data...
  • Chandra Deep Field-South survey: 7Ms sources

    We present X-ray source catalogs for the ~7Ms exposure of the Chandra Deep Field-South (CDF-S), which covers a total area of 484.2arcmin^2^. Utilizing wavdetect for initial...
  • CLASH-VLT: the FF cluster MACS J0416.1-2403

    We present VIMOS-Very Large Telescope (VLT) spectroscopy of the Frontier Fields (FF) cluster MACS J0416.1-2403 (z=0.397). Taken as part of the CLASH-VLT survey, the large...
