Group

NWO_logo_nl-300x149In 2016 I started a new research group at the Anton Pannekoek Institute for Astronomy (API) of the University of Amsterdam, owing to an NWO Vidi grant. The API is a wonderful and vibrant institute to work at, and Amsterdam is an exciting city to live in.

My Vidi project focuses on studying the physics of accretion flows around neutron stars and black holes in a relatively unexplored regime between bright outbursts (very active accretion) and quiescence (very little accretion). The main aims is to perform a systematic, in-depth analysis of this transition regime using radio, infrared, optical, UV and X-ray observations from various Earth-based and space-based telescopes. The prime instruments we work with in my group are the Hubble Space Telescope, NuSTAR, Chandra, XMM-Newton, Swift and NICER satellites, the Isaac Newton Telescope (2.5m),  Magellan (6.5-m), Gemini (8-m), and Very Large Telescope (8-m) observatories, as well as the Very Large Array and Australia Telescope Compact Array radio facilities.
