  • Connecting galaxy structure and star formation

    In this work, we investigate the reason behind the increased occurrence of S0 galaxies in high-density environments. Our sample comprises of ~2500 spiral and ~2000 S0 galaxies...
  • Broad-line velocity shifts in 1.5<z<7.5 quasars

    We present the results of a model-independent investigation of the rest-frame UV spectra from a comprehensive sample of 394 quasars in the redshift range 1.5=<z=<7.5. We...
  • Multiwavelength observations of GD 394

    We present new Hubble Space Telescope (HST) ultraviolet and ground-based optical observations of the hot, metal-rich white dwarf GD 394. Extreme-ultraviolet (EUV) observations...
  • LVHIS. far-infrared radio correlation

    In this paper we measure the far-infrared (FIR) and radio flux densities of a sample of 82 local gas-rich galaxies, including 70 "dwarf" galaxies (M_*<10^9^M{sun}_), from the...
  • High-z LAEs and LBGs in SHARDS survey

    We have undertaken a comprehensive search for both Lyman alpha emitters (LAEs) and Lyman break galaxies (LBGs) in the Survey for High-z Absorption Red and Dead Sources (SHARDS)...
  • Luminous Ly{alpha} emitters at z~2-3

    Deep narrow-band surveys have revealed a large population of faint Ly{alpha} emitters (LAEs) in the distant Universe, but relatively little is known about the most luminous...
  • SC4K catalogue of candidate LAEs

    We present and explore deep narrow- and medium-band data obtained with the Subaru and the Isaac Newton Telescopes in the ~2deg^2^ COSMOS field. We use these data as an extremely...
  • Catalog of Ly{alpha} emitters

    We present a measurement of the fraction of Lyman {alpha} (Ly{alpha}) emitters (X_Ly{alpha}) amongst HST continuum-selected galaxies at 3<z<6 with the Multi-Unit...
  • Candidate LAEs at z=5.7 and z=6.6

    We present spectroscopic follow-up of candidate luminous Ly{alpha} emitters (LAEs) at z=5.7-6.6 in the SA22 field with VLT/X-SHOOTER. We confirm two new luminous LAEs at z=5.676...
  • Damped Lyman Alpha systems equivalent width

    We derive the statistical properties of neutral gas at redshifts 0.11<z<1.65 from ultraviolet (UV) measurements of quasar Ly{alpha} absorption lines corresponding to 369...
  • LAE among star-forming galaxies at z=2.5

    We conducted a deep narrow-band imaging survey with the Subaru Prime Focus Camera on the Subaru Telescope and constructed a sample of Ly{alpha} emitters (LAEs) at z=2.53 in the...
  • ZFOURGE catalogue of AGN candidates

    We investigate active galactic nuclei (AGN) candidates within the FourStar Galaxy Evolution Survey (ZFOURGE) to determine the impact they have on star formation in their host...
  • Local SDSS galaxies in Herschel Stripe 82

    We study a set of 3319 galaxies in the redshift interval 0.04<z<0.15 Herschel/SPIRE 250{mu}m band. Total infrared (TIR) luminosities derived from HerS and Wide-field...
  • WFC3/UVIS quasar-stacked spectrum at z=~2.4

    The ionizing continuum from active galactic nuclei is fundamental for interpreting their broad emission lines and understanding their impact on the surrounding gas. Furthermore,...
  • Type Ia SN environment within host galaxies

    We present constraints on Type Ia supernovae (SNe Ia) progenitors through an analysis of the environments found at the explosion sites of 102 events within star-forming host...
  • MgII UV feature in T Tauri stars

    The atmospheric structure of T Tauri stars (TTSs) and its connection with the large-scale outflow is poorly known. Neither the effect of the magnetically mediated interaction...
  • ExoMol line lists for formaldehyde H_2_CO

    A computed line list for formaldehyde, H_2_^12^C^16^O, applicable to temperatures up to T=1500K is presented. An empirical potential energy and ab initio dipole moment surfaces...
  • ExoMol line lists for phosphine (PH_3_)

    A comprehensive hot line list is calculated for ^31^PH_3_ in its ground electronic state. This line list, called SAlTY, contains almost 16.8 billion transitions between 7.5...
  • Giant Gemini GMOS survey. I.

    We present spectra of 163 quasars at z_em_>4.4 taken with the Gemini Multi Object Spectrometers, the largest publicly available sample of high-quality (signal-to-noise ratio...
  • Early-Type Galaxies in SDSS and GALEX

    We use the Hernandez-Perez and Bruzual stellar population synthesis models to study the role of interacting binary pairs as progenitors of extreme horizontal branch (EHB) stars....
