    • A 3D extinction map of the northern Galactic plane based on IPHAS photometry 

      Sale, S. E.; Drew, J.E.; Barentsen, G.; Farnhill, H. J.; Raddi, R.; Barlow, M. J.; Eisl̈offel, J.; Vink, J. S.; Rodŕiguez-Gil, P.; Wright, N. J. (2014-10-01)
      We present a 3D map of extinction in the northern Galactic plane derived using photometry from the INT/WFC Photometric Hα Survey of the northern Galactic plane. The map has fine angular (~10 arcmin) and distance (100 pc) ...
    • Classical T Tauri stars with VPHAS+ -I : H α and u-band accretion rates in the Lagoon Nebula M8 

      Kalari, V. M.; Vink, J. S.; Drew, J.E.; Barentsen, G.; Drake, J. J.; Eislöffel, J.; Martín, E.L.; Parker, Q. A.; Unruh, Y.C.; Walton, N. A.; Wright, N. J. (2015-10-11)
      We estimate the accretion rates of 235 Classical T Tauri star (CTTS) candidates in the Lagoon Nebula using $ugri$H$\alpha$ photometry from the VPHAS+ survey. Our sample consists of stars displaying H$\alpha$-excess, the ...
    • Diffuse X-Ray Emission in the Cygnus OB2 Association 

      Albacete-Colombo, J. F.; Drake, J. J.; Flaccomio, E.; Wright, N. J.; Kashyap, V.; Guarcello, M. G.; Briggs, K.; Drew, J. E.; Fenech, D. M.; Micela, G.; McCollough, M.; Prinja, R. K.; Schneider, N.; Sciortino, S.; Vink, J. S. (2023-11-01)
      We present a large-scale study of diffuse X-ray emission in the nearby massive stellar association Cygnus OB2 as part of the Chandra Cygnus OB2 Legacy Program. We used 40 Chandra X-ray ACIS-I observations covering ∼1.0 ...
    • New OB star candidates in the Carina Arm around Westerlund 2 from VPHAS+ 

      Mohr-Smith, M.; Drew, J.E.; Barentsen, G.; Wright, N. J.; Napiwotzki, R.; Corradi, R.L.M.; Eislöffel, J.; Groot, P.; Kalari, V.; Parker, Q. A.; Raddi, Roberto; Sale, S. E.; Unruh, Y.C.; Vink, J. S.; Wesson, R. (2015-07-11)
      O and early B stars are at the apex of galactic ecology, but in the Milky Way, only a minority of them may yet have been identified. We present the results of a pilot study to select and parametrise OB star candidates in ...
