  • Newly spectroscopically confirmed DB white dwarfs

    Using a machine learning (ML) method, we mine DB white dwarfs (DBWDs) from the Sloan Digital Sky Survey (SDSS) Data Release (DR) 12 and DR14. The ML method consists of two...
  • Calibration sample UBV and GALEX photometry

    We derive transformation equations between GALEX and UBV colours by using the reliable data of 556 stars. We present two sets of equations: as a function of (only) luminosity...
  • IGM Neutral Fraction Inference

    We present a Bayesian inference on the neutral hydrogen fraction of the intergalactic medium (IGM), {bar}x_hi_, at z~6-8 using the properties of Lyman break galaxies during the...
  • Relative specific Type Ia supernovae rate

    We analyse the 476 SN Ia host galaxies from the All-Sky Automated Survey for Supernova (ASAS-SN) Bright Supernova Catalogues to determine the observed relative Type Ia supernova...
  • Compact group galaxies UV and IR SFR

    Compact groups of galaxies provide insight into the role of low-mass, dense environments in galaxy evolution because the low velocity dispersions and close proximity of galaxy...
  • Host galaxies of Superluminous Supernovae

    We present Hubble Space Telescope (HST) Wide Field Camera 3 UV and near-IR (nIR) imaging of 21 Superluminous Supernovae (SLSNe) host galaxies, providing a sensitive probe of...
  • Swift/UVOT sources in NGC4321 (M100)

    We study the star-forming regions in the spiral galaxy NGC 4321 (M100). We take advantage of the spatial resolution (2.5-arcsec full width at half-maximum) of the...
  • NGC 6752 multiwavelength survey

    We present the results of a multiwavelength (far-ultraviolet to I band) survey of the stellar populations of the globular cluster NGC 6752, using Space Telescope Imaging...
  • UV-selected galaxy redshift survey

    The table contains the first results of a spectroscopic survey of galaxies constructed from a flux-limited sample of stars, galaxies and QSOs imaged at 2000{AA} with the FOCA...
  • The ELQS in the PS1 footprint (PS-ELQS)

    We present the results of the Extremely Luminous Quasar Survey in the 3{pi} survey of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS; PS1). This effort...
  • CANDELS/SHARDS multiwavelength cat. in GOODS-N

    We present a WFC3 F160W (H-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts,...
  • UV variability with GALEX gPhoton archive. I.

    In order to develop and test a methodology to search for UV variability over the entire Galaxy Evolution Explorer (GALEX) database down to the shortest timescales, we analyzed...
  • Merging dwarf galaxies in the local universe

    We present the largest publicly available catalog of interacting dwarf galaxies. It includes 177 nearby merging dwarf galaxies of stellar mass M*<10^10^M_{sun}_ and redshifts...
  • 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...
  • 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...
  • UV and optical obs. of type Ic SN 2020oi

    We present photometric and spectroscopic observations of Supernova 2020oi (SN 2020oi), a nearby (~17Mpc) type-Ic supernova (SNIc) within the grand-design spiral M100. We...
  • Final moments. I. Type II SN 2020tlf

    We present panchromatic observations and modeling of supernova (SN) 2020tlf, the first normal Type II-P/L SN with confirmed precursor emission, as detected by the Young...
  • Swift UVOT observation of the radio quasar 3C 273

    3C273 is an intensively monitored flat-spectrum radio quasar with both a beamed jet and blue bump together with broad emission lines. The coexistence of the comparably prominent...
  • Swift UVOT light curves of ASASSN-15lh

    We present the detection of persistent soft X-ray radiation with L_x_~10^41^-10^42^erg/s at the location of the extremely luminous, double-humped transient ASASSN-15lh as...
  • Swift-UVOT obs. analysis of 29 SNe Ia

    The intrinsic colors of Type Ia supernovae (SNe Ia) are important to understanding their use as cosmological standard candles. Understanding the effects of reddening and...
