  • IPHAS DR2 Source Catalogue

    The INT/WFC Photometric H-Alpha Survey of the Northern Galactic Plane (IPHAS) is a 1860 deg^2^ imaging survey of the Northern Milky Way at red visible wavelengths. It covers...
  • Malin 1 MUSE images

    Giant low-surface brightness (GLSB) galaxies are an extreme class of objects with very faint and extended gas-rich disks. Malin 1 is the largest GLSB galaxy known to date, but...
  • IGAPS. merged IPHAS and UVEX of northern Galactic plane

    The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT) obtained between 2003...
  • VPHAS+ DR2 survey

    The primary goal of the VST Photometric H{alpha} Survey of the Southern Galactic Plane and Bulge (VPHAS+) is to collect single-epoch ugri broad-band and Ha narrow-band...
  • Halpha datacubes of the Carina arm tangency

    The arm tangent direction provides a unique viewing geometry, with a long path in relatively narrow velocity ranges and lines of view that cross the arm perpendicular to its...
  • 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...
  • HII regions in OB associations

    Using the data from the NOAO Local Group Survey, we have measured the H{alpha} fluxes of 291 nebulae associated with 21 of the van den Bergh OB associations. We have combined...
  • HII regions of M33. II.

    We have identified a total of 1272 newly recognized emission regions in M33. Combined with the previously cataloged total of 1066 H II regions and supernova remnants, this...
  • Be stars in MC star clusters NIR properties

    Magellanic Clouds are the nearby galaxies which are ideal to study the properties of metal poor stellar population. In this study, we explore the near-IR properties of optically...
  • UBVRIH{alpha} of {eta} Car in 2009

    The periodic events occurring in {eta} Carinae have been widely monitored during the last three 5.5-year cycles. The last one recently occurred in January 2009 and more...
  • HII regions in NGC 6384

    The galaxy NGC6384 has been observed with an IPCS through H{alpha} and [NII] narrow-band interference filters for direct imagery with the 2.6-m Byurakan telescope. We studied...
  • Halpha and other SFR indicators

    We present new H{alpha} photometry for the Star Formation Reference Survey (SFRS), a representative sample of star-forming galaxies in the local Universe. Combining these data...
  • SFR in Local Volume late-type galaxies

    Using a currently most representative sample of 477 late-type galaxies within 11Mpc of the Milky Way with measured star formation rates (SFRs) from the far-ultraviolet (FUV) and...
  • Gaia/IPHAS catalogue of Ha-excess sources

    We present a catalogue of point-like H{alpha}-excess sources in the Northern Galactic Plane. Our catalogue is created using a new technique that leverages astrometric and...
  • NGC 6383 T Tauri accretion rates

    This paper presents optical (ugriH{alpha})-infrared (JHKs, 3.6-8.0um) photometry and Gaia astrometry of 55 Classical T-Tauri stars (CTTS) in the star-forming region Sh 2-012 and...
  • Machine learning to identify symbiotic stars

    In this second paper in a series of papers based on the most-up-to-date catalogue of symbiotic stars (SySts), we present a new approach for identifying and distinguishing SySts...
  • Velocity dispersions for CALIFA Galaxies

    We present tables of velocity dispersions derived from CALIFA V1200 datacubes using PIPE3D. Four different dispersions are extracted from emission (ionized gas) or absorption...
  • Candidate Halpha sources in GBS

    We present a catalogue of candidate Halpha emission and absorption line sources and blue objects in the Galactic Bulge Survey (GBS) region. We use a point source catalogue of...
  • Deep OB star population in Carina

    Massive OB stars are critical to the ecology of galaxies, and yet our knowledge of OB stars in the Milky Way, fainter than V~12, remains patchy. Data from the VST Photometric...
  • Chandra Galactic Bulge Survey

    As part of the Chandra Galactic Bulge Survey (GBS), we present a catalogue of optical sources in the GBS footprint. This consists of two regions centered at Galactic latitude...
