    • Chandra observations of Cygnus OB2 

      Wright, N.J.; Drake, Jeremy J.; Drew, J.E.; Vink, Jorick S. (Springer Nature, 2012)
      Cygnus OB2 is the nearest example of a massive star forming region, containing over 50 O-type stars and hundreds of B-type stars.We have analyzed two Chandra pointings in Cyg OB2, detecting ∼1,700 X-ray sources, of which ...

    • The deep OB-star population in Carina from the VST Photometric H-alpha Survey (VPHAS+) 

      Mohr-Smith, M.; Drew, Janet; Napiwotzki, Ralf; Simon-Diaz, S.; Wright, N. J.; Barentsen, Geert; Eisloeffel, J.; Farnhill, Hywel; Greimel, R.; Monguio, Maria; Kalari, V.; Parker, Q. A.; Vink, Jorick S. (2017-02-21)
      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 Hα Survey (VPHAS+) permit the construction of ...

    • Internal entrainment and the origin of jet-related broad-band emission in Centaurus A 

      Wykes, Sarka; Hardcastle, M.J.; Karakas, Amanda I.; Vink, Jorick S. (2015-02-11)
      The dimensions of Fanaroff-Riley class I jets and the stellar densities at galactic centres imply that there will be numerous interactions between the jet and stellar winds. These may give rise to the observed diffuse and ...

    • T Tauri candidates and accretion rates using IPHAS : method and application to IC 1396 

      Barentsen, Geert; Vink, Jorick S.; Drew, J.E.; Greimel, R.; Wright, Nick; Drake, J. J.; Martin, E.L.; Valdivielso, L.; Corradi, R.L.M. (2011-07)
      The Isaac Newton Telescope (INT) Photometric H-Alpha Survey (IPHAS) is a 1800 deg(2) survey of the Northern Galactic Plane, reaching down to r' similar to 21. We demonstrate how the survey can be used to (1) reliably select ...

    • A Tale of Three Cities : OmegaCAM discovers multiple sequences in the color-magnitude diagram of the Orion Nebula Cluster 

      Beccari, G.; Petr-Gotzens, M.G.; Boffin, H.M.J.; Romaniello, M.; Fedele, D.; Carraro, G.; Marchi, G. De; de Wit, W.J.; Drew, J. E.; Kalari, V. M.; Manara, Carlo Felice; Martin, Eduardo L.; Mieske, S.; Panagia, N.; Testi, L.; Vink, Jorick S.; Walsh, J. R.; Wright, N. J. (2017-07-27)
      As part of the Accretion Discs in H$\alpha$ with OmegaCAM (ADHOC) survey, we imaged in r, i and H-alpha a region of 12x8 square degrees around the Orion Nebula Cluster. Thanks to the high-quality photometry obtained, we ...

    • 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 ...
