    Profile

    Nathalie Degenaar is an Vidi/NWO group leader at the University of Amsterdam. After completing her PhD at the University of Amsterdam in 2010, she was a NASA Hubble fellow at the University of Michigan (Ann Arbor, USA) and a Marie Curie fellow at the Institute of Astronomy of the University of Cambridge (UK) before moving to Amsterdam in 2017. She is an NWO Vidi Laureate and leads the research group that focusses on multi-wavelength studies of accreting compact objects (IMPACT: In/outflow: the Mass-transfer and Power of Accreting Compact objecTs). More information about her research and group can be found here.

    Research and teaching

    Her current research focusses on studying the properties of accretion flows in X-ray binaries. Using X-ray, UV, optical, near-infrared and radio observations from various ground-based and space-based telescopes, her goal is to i) understand accretion and associated outflows across the scale of accretion rates, and ii) reveal exotic X-ray binaries of which only small numbers have been identified to date. She is also the principal investigator of a daily X-ray monitoring campaign of the Galactic center, which she uses to study transient X-ray binaries and the Milky Way’s supermassive black hole, Sagittarius A*.

    Keywords 

    Neutron stars, thermonuclear bursts, black holes, accretion, outflows
