      Anderson, G.E.; Gaensler, B.M.; Kaplan, D.L.A.; Slane, P.O.; Muno, M.P.; Posselt, B.; Hong, J.; Murray, Stephen S.; Steeghs, D.T.H.; Brogan, C.L.; Drake, Jeremy J.; Farrell, S.A.; Benjamin, R.A.; Chakrabarty, D.; Drew, J.E.; Finley, J.P.; Grindlay, J.E.; Lazio, T.J.W.W.; Lee, J.C.; Mauerhan, J.C.; Van Kerkwijk, M.H. (2014-05)
      We present the Chasing the Identification of ASCA Galactic Objects (ChIcAGO) survey, which is designed to identify the unknown X-ray sources discovered during the ASCA Galactic Plane Survey (AGPS). Little is known about ...

    • 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 ...

    • Tracing the structure of the Perseus arm with IPHAS 

      Raddi, Roberto; Drew, J.E.; Sale, S.E.; Steeghs, D.T.H. (Springer Nature, 2012)
      Research aiming to describe the spiral structure of the Milky Way disc has to confront both difficulties in obtaining distances and the high interstellar extinction found in the Galactic plane. We present a study of a ...
