    • Emission Line Stars In and Beyond the Perseus Arm 

      Raddi, Roberto (University of Hertfordshire, 2013-04-23)
      I present low-resolution (Dl 6 A° ) follow-up spectroscopy of 370 Ha emitters (12 . r . 17) identified with IPHAS, in a 100 deg2 wide section of the Galactic plane that is located between ` = (120 ; 140 ) and b = (􀀀1 ...

    • Optical Digital Galactic Plane Surveys and Star-Cluster Science 

      Drew, J.E.; Raddi, Roberto; EGAPS Consortia (Springer Nature, 2012)
      Over the next few years, the optical surveys IPHAS, UVEX and VPHAS+ will provide complete photometric coverage of the Galactic Plane within the latitude range -5 degrees <b <+5 degrees. Of these surveys, IPHAS is the most ...

    • 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 ...
