Winds from the accretion flow in stellar and supermassive black holes

Séminaire IPAG de Chris Done (Durham University), jeudi 12 novembre 2020, 11h00, IPAG seminar room, online seminar

I will review both observations of winds from the accretion flow as seen by blueshifted absorption lines in both the black hole binaries and the active galaxies.
I will show how these can be mostly understood from theoretical models for their launch and acceleration, and highlight the challenges remaining in our knowledge which can be addressed with higher resolution.
