    • A determination of the space density and birth rate of hydrogen-line (DA) white dwarfs in the Galactic plane, based on the UVEX survey 

      Verbeek, Kars; Groot, Paul J.; Nelemans, Gijs A.; Scaringi, Simone; Napiwotzki, R.; Drew, J.E.; Steeghs, D.T.H.; Casares, Jorge; Corral-Santana, J.M.; Gänsicke, Boris T.; González-Solares, E.A.; Greimel, Robert; Heber, Ulrich; Irwin, Mike J.; Knigge, Christian; Wright, N.J.; Zijlstra, Albert (2013-10-01)
      We present a determination of the average space density and birth rate of hydrogen-line (DA) white dwarfs within a radius of 1 kpc around the Sun, based on an observational sample of 360 candidate white dwarfs with g <19.5 ...

    • A first catalogue of automatically selected ultraviolet-excess sources from the UVEX survey 

      Verbeek, Kars; de Groot, Eelco; Groot, Paul J.; Scaringi, Simone; Drew, J.E.; Greimel, Robert; Irwin, Mike; Gonzalez-Solares, Eduardo; Gaensicke, Boris T.; Casares, Jorge; Corral-Santana, Jesus M.; Deacon, Niall; Steeghs, Danny (2012-02)
      We present the first catalogue of point-source ultraviolet (UV)-excess sources selected from the UV-Excess Survey of the Northern Galactic Plane (UVEX). UVEX images the Northern Galactic Plane in the U, g, r and He Iota ...

    • The OmegaWhite Survey for Short-Period Variable Stars - I : Overview and First Results 

      Macfarlane, S. A.; Toma, R.; Ramsay, G.; Groot, Paul J.; Woudt, P. A.; Drew, J.E.; Barentsen, G.; Eisloffel, J. (2015-11-21)
      We present the goals, strategy and first results of the OmegaWhite survey: a wide-field high-cadence g-band synoptic survey which aims to unveil the Galactic population of short-period variable stars (with periods <80 min), ...

    • Ultraviolet-excess sources with a red/infrared counterpart : Low-mass companions, debris discs and QSO selection 

      Verbeek, K.; Groot, Paul J.; Scaringi, Simone; Casares, Jorge; Corral-Santana, Jesus M.; Deacon, Niall; Drew, J.E.; Gänsicke, B.T.; Gonzalez-Solares, E.; Greimel, R.; Heber, U.; Napiwotzki, R.; Ostensen, R.H.; Steeghs, D.; Wright, N.J.; Zijlstra, A. (2014-02)
      We present the result of the cross-matching between ultraviolet (UV)-excess sources selected from the UV-Excess Survey of the Northern Galactic Plane (UVEX) and several infrared (IR) surveys (2MASS, UKIDSS and WISE). From ...

    • The VST photometric hα survey of the Southern Galactic Plane and Bulge (VPHAS+) 

      Drew, J.E.; González-Solares, Eduardo A.; Greimel, Robert; Irwin, M.J.; Küpcü Yoldaş, A.; Lewis, J.R.; Barentsen, Geert; Eislöffel, Jochen; Farnhill, Hywel J.; Martin, Bill; Walton, Nicholas A.; Mohr-Smith, M.; Raddi, Roberto; Sale, Stuart E.; Wright, Nicholas J.; Groot, Paul J.; Barlow, Michael J.; Corradi, R.L.M.; Drake, Jeremy J.; Fabregat, Juan; Frew, David J.; Gänsicke, Boris T.; Knigge, Christian; Mampaso, Antonio; Morris, R.A.H.; Naylor, Tim J.; Parker, Quentin A.; Phillipps, Steven; Ruhland, Christine; Steeghs, Danny T H; Unruh, Y.C.; Vink, Jorick S.; Wesson, Roger; Zijlstra, Albert (2014-05-21)
      The VST Photometric Hα Survey of the Southern Galactic Plane and Bulge (VPHAS+) is surveying the southern Milky Way in u, g, r, i and Hα at ~1 arcsec angular resolution. Its footprint spans the Galactic latitude range -5o ...
