Biography

Anne Verhamme obtained her PhD degree in Astronomy at the AV短视频 (Switzerland) in 2008, under supervision of D. Schaerer, working on Lyman-alpha radiation transfer effects in galaxies. In 2009, she was an SNF fellow at the Astrophysics department of Oxford AV短视频, working in the galaxy formation group with J. Silk, A. Slyz and J. Devriendt. From 2010 to 2012, she obtained a european Marie Curie fellowship to work at CRAL, in Lyon, in the galaxy formation team with R. Bacon, PI of VLT-MUSE, and J. Blaizot, to compute the Lyman-alpha properties of virtual galaxies. Since sept 2012, she has an independent post-doc position at the AV短视频 (Excellence Fellow of the AV短视频 for 3 years, 鈥淢arie Heim Vogtlin鈥� SNF Fellow for 2 years) and works on spectral diagnostics to study the escape of ionising photons and gas flows around galaxies, at the interface between simulations (coupling our radiation transfer code with radiation hydrodynamical simulations of galaxy formation) and observations (as a member of the MUSE consortium, and Associated Researcher at CRAL, Lyon).

She currently works on new methods to select galaxies which emit ionising flux, those which probably reionised the Universe, from their Lyman-alpha properties (spectral shape and/or extend of their Lya halos), with a newly developed radiation transfer code, RASCAS, 听efficiently parallelised, and interfaced with state-of-the-art radiation hydrodynamic (RHD) simulations of galaxy formation.
