ABSTRACT
A substantial fraction of quasars display broad absorption lines (BALs) in their rest-frame ultraviolet spectra. While the origin of BALs is thought to be related to the accretion disc wind, it remains unclear whether the observed ratio...

The Event Horizon Telescope (EHT) recently produced the first horizon-scale
image of a supermassive black hole. Expanding the array to include a 3-meter
space telescope operating at >200 GHz enables mass measurements of many black
holes, movies of...
