  • ELAIS N1 field uGMRT 400MHz source catalog

    Understanding the low-frequency radio sky in depth is necessary to subtract foregrounds in order to detect the redshifted 21 cm signal of neutral hydrogen from the cosmic dawn,...
  • Open Supernova Catalog anomaly detection

    In the upcoming decade, large astronomical surveys will discover millions of transients raising unprecedented data challenges in the process. Only the use of the machine...
  • CVRHS classifications for the EFIGI Galaxy Sample

    This paper is the third which examines galaxy morphology from the point of view of comprehensive de Vaucouleurs revised Hubble-Sandage (CVRHS) classification, a variation on the...
  • CVRHS classifications for 719 AMIGA galaxies

    Using images from Sloan Digital Sky Survey Data Release 8, we have re-examined the morphology of 719 galaxies from the Analysis of the interstellar Medium in Isolated GAlaxies...
  • 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...
  • NGC 3115 Stellar Populations and Kinematics

    We present a combination of the Schwarzschild orbit-superposition dynamical modelling technique with the spatially-resolved mean stellar age and metallicity maps to uncover the...
  • Morphology of 16908 SDSS Stripe 82 galaxies

    Quantitative characterization of galaxy morphology is vital in enabling comparison of observations to predictions from galaxy formation theory. However, without significant...
  • HiZELS star-forming galaxies at z=0.8-3.3

    We present adaptive optics assisted integral field spectroscopy of 34 star-forming galaxies at z=0.8-3.3 selected from the HiZELS narrow-band survey. We measure the kinematics...
  • Morphological study of galaxies in ZwCl0024+1652

    The well-known cluster of galaxies ZwCl0024+1652 at z~0.4 lacks an in-depth morphological classification of its central region. While previous studies provide a visual...
  • Star-galaxy multi narrow-band classification

    Classification of stars and galaxies is a well-known astronomical problem that has been treated using different approaches, most of them relying on morphological information. In...
  • 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...
  • S4G galaxies disk/bar decomposition

    We present photometric models of 532 disc galaxies in 3.6um images from the Spitzer Survey of Stellar Structure in Galaxies (S^4^G) using the non-parametric DISKFIT algorithm....
  • SPIDERS BCGs gri photometry

    We present a sample of 329 low-to intermediate-redshift (0.05<z<0.3) brightest cluster galaxies (BCGs) in X-ray-selected clusters from the SPectroscopic IDentification of...
  • Structural properties of faint LSB galaxies

    We study the structural properties of Low-Surface-Brightness galaxies (LSB) using a sample of 263 galaxies observed by the Green Bank Telescope. We perform 2D decompositions of...
  • SDSS galaxies classification

    We present an automated method for the detection of bar structure in optical images of galaxies using a deep convolutional neural network that is easy to use and provides good...
  • Photometric catalogue of CALIFA galaxies

    We present an extensive compendium of photometrically determined structural properties for all Calar Alto Legacy Integral Field spectroscopy Area (CALIFA)galaxies in the third...
  • Abell S1063 and MACS J1149.5+2223 photometry

    We analyse the Kormendy relations (KRs) of the two Frontier Fields clusters, Abell S1063, at z=0.348, and MACS J1149.5+2223, at z=0.542, exploiting very deep Hubble Space...
  • Stellar angular momentum for MaNGA galaxies

    We measure {lambda}Re, a proxy for galaxy specific stellar angular momentum within one effective radius, and the ellipticity, {epsilon}, for about 2300 galaxies of all...
  • Mass models of 171 galaxies

    Mass models of a sample of 171 low- and high-surface brightness galaxies are presented in the context of the cold dark matter (CDM) theory using the NFW dark matter halo density...
  • GAMA. galaxy structure across green valley

    Using a sample of 472 local Universe (z<0.06) galaxies in the stellar mass range 10.25<logM*/M_{sun}_<10.75, we explore the variation in galaxy structure as a function...
