  • K2-2 b: light curves and radial velocities

    K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5+/-0.1R_{Earth}, 9.7+/-1.2M{Earth}_) orbiting a...
  • Sextans dwarf spheroidal members

    The Sextans dwarf spheroidal galaxy has been challenging to study in a comprehensive way as it is highly extended on the sky, with an uncertain but large tidal radius of between...
  • Carnegie Supernova Project. II. NIR sp. of SNIa

    We present the largest and most homogeneous collection of near-infrared (NIR) spectra of Type Ia supernovae (SNe Ia): 339 spectra of 98 individual SNe obtained as part of the...
  • New velocity measurements of NGC 5128 GCs

    We present new radial velocity measurements from the Magellan and the Anglo-Australian Telescopes for 175 previously known and 121 newly confirmed globular clusters (GCs) around...
  • MASH Catalogues of Planetary Nebulae

    The Macquarie/AAO/Strasbourg H{alpha} Planetary Nebula Catalogue (MASH) contains 903 new true, likely and possible Galactic Planetary Nebulae (PNe) discovered from the AAO/UKST...
  • SOLAR-ISS Spectrum covering 165-3000nm

    The accurate measurement of the solar spectrum at the top of the atmosphere and its variability are fundamental inputs for solar physics (Sun modeling), terrestrial atmospheric...
  • SOLAR/SOLSPEC UV SSI from 2008-2015

    Accurate measurements of the solar spectral irradiance (SSI) and its temporal variations are of primary interest to better understand solar mechanisms, and the links between...
  • 51 Eri b near-infrared spectrum

    Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric composition and luminosity, which is influenced by their formation...
  • Spectral line identification in 3 Pup

    Optical spectra taken in 1997-2008 are used to analyze the spectral peculiarities and velocity field in the atmosphere of the peculiar supergiant 3 Pup.
  • Census of circumgalactic MgII at redshift z=<0.5

    This paper presents a survey of MgII absorbing gas in the vicinity of 380 random galaxies, using 156 background quasi-stellar objects (QSOs) as absorption-line probes. The...
  • Sub-damped Lyman {alpha} systems in XQ-100 II

    We present the measured gas-phase metal column densities in 155 sub-damped Ly {alpha} systems (subDLAs) with the aim to investigate the contribution of subDLAs to the chemical...
  • New classical Ae stars using LAMOST DR5

    We report the first systematic study to identify and characterize a sample of classical Ae stars in the Galaxy. The spectra of these stars were retrieved from the A-star...
  • Temperature and metallicity scale of cool giants

    We present here quantitative diagnostic tools for cool giants that employ low-resolution near-infrared spectroscopy in the K band for stellar population studies. In this study,...
  • Neural networks for spectral classification

    Due to the ever-expanding volume of observed spectroscopic data from surveys such as SDSS and LAMOST, it has become important to apply artificial intelligence (AI) techniques...
  • MIR spectra of AGNs heating molecular gas

    We analyse 2015 mid-infrared (MIR) spectra of galaxies observed with Spitzer's Infrared Spectrograph, including objects with growing supermassive black holes (SMBHs) and objects...
  • Chemical compositions of Galactic bulge stars

    This work explores the detailed chemistry of the Milky Way bulge using the HERMES spectrograph on the Anglo-Australian Telescope. Here, we present the abundance ratios of 13...
