  • AGES: the AGN and Galaxy Evolution Survey

    The AGN and Galaxy Evolution Survey (AGES) is a redshift survey covering, in its standard fields, 7.7deg^2^ of the Bootes field of the NOAO Deep Wide-Field Survey. The final...
  • GALEX catalog of star clusters in M31

    We present a comprehensive catalog of 700 confirmed star clusters in the field of M31 compiled from three major existing catalogs. We detect 418 and 257 star clusters in Galaxy...
  • UV to far-IR photometry of galaxies

    In this paper, we present a sample of cluster galaxies devoted to study the environmental influence on the star formation activity. This sample of galaxies inhabits in clusters...
  • Photometry catalogs for the Lockman Hole

    We present broadband photometry and photometric redshifts for 187611 sources located in ~0.5deg^2^ in the Lockman Hole area. The catalog includes 388 X-ray-detected sources...
  • Spitzer/IRAC sources in the EGS I. SEDs

    We present an IRAC 3.6+4.5um selected catalog in the Extended Groth Strip (EGS) containing photometry from the ultraviolet to the far-infrared and stellar parameters derived...
  • Deep GALEX observations of the Coma cluster

    We present a source catalog from a deep 26ks Galaxy Evolution Explorer (GALEX) observation of the Coma cluster in the far-UV (FUV; 1530{AA}) and near-UV (NUV; 2310{AA})...
  • The simultaneous optical-to-X-ray SED of AGNs

    We report Swift observations of a sample of 92 bright soft X-ray selected active galactic nuclei (AGNs). This sample represents the largest number of AGNs observed to study the...
  • UV-bright quasars

    Absorption along quasar sightlines remains among the most sensitive direct measures of HeII reionization in much of the intergalactic medium (IGM). Until recently, fewer than a...
  • GALEX UV photometry of M31 Globular Clusters

    We present ultraviolet (UV) photometry of M31 globular clusters (GCs) found in 23 Galaxy Evolution Explorer (GALEX) images covering the entirety of M31. We detect 485 and 273...
  • UV-to-FIR magnitudes for 83 starburst galaxies

    We present a database of UV-to-FIR data of 83 nearby starburst galaxies. The galaxies are selected based upon the availability of IUE data. We have recalibrated the IUE UV...
  • HST photometry of 4 Virgo LSB galaxies

    Utilizing the F814W and F300W filters, Hubble Space Telescope Wide Field Planetary Camera-2 (WFPC2) images were taken of four low surface brightness galaxies in the direction of...
  • Star Clusters in M33

    In this paper we present the discovery of 60 star clusters in 20 multiband Hubble Space Telescope (HST) WFPC2 fields in M33. The fields sample a variety of environments, from...
  • Virgo cluster ultraviolet sources

    We analyze three UV images covering a ~100 square degree field toward the Virgo cluster, obtained by the FAUST space experiment. We detect 191 sources to a signal-to-noise ratio...
  • Doppler beaming factors in binary stars

    The Doppler beaming effect, induced by the reflex motion of stars, introduces flux modulations and serves as an efficient method to photometrically determine mass functions for...
  • Hydrogen-poor superluminous SNe from ZTF Phase I. I.

    During the Zwicky Transient Facility (ZTF) Phase I operations, 78 hydrogen-poor superluminous supernovae (SLSNe-I) were discovered in less than 3yr, constituting the largest...
  • Mid-IR PAH features of SINGS galaxies

    We combined mapping-mode mid-infrared Spitzer spectra with complementary infrared imaging to perform a spatially resolved study of polycyclic aromatic hydrocarbon (PAH) emission...
  • The GALEX-PTF experiment. II. Core-collapse SNe

    The radius and surface composition of an exploding massive star, as well as the explosion energy per unit mass, can be measured using early ultraviolet (UV) observations of...
  • Photometry & spectroscopy follow-up of ASASSN-20hx

    We present observations of ASASSN-20hx, a nearby ambiguous nuclear transient (ANT) discovered in NGC 6297 by the All-Sky Automated Survey for Supernovae (ASAS-SN). We observed...
  • UV, optical and X-ray evolution of ASASSN-14ko

    ASASSN-14ko is a recently discovered periodically flaring transient at the center of the active galactic nucleus (AGN) ESO 253-G003 with a slowly decreasing period. Here, we...
  • Type Ia SNe with galaxy host properties

    More luminous Type Ia supernovae prefer less massive hosts and regions of higher star formation. This correlation is inverted during width-color-luminosity light-curve...
