Swift discovers X-rays from the newly discovered tidal disruption flare candidate AT2019dsg
Abstract
The optical transient AT2019dsg was discovered on 4th April 2019 by the Zwicky Transient Facility. A follow-up optical spectrum revealed a blue continuum superposed with both narrow Balmer emission lines (from the host galaxy, at z=0.051) as well as a broad He II 4686 emission feature and potentially a broad H-alpha feature (ATEL#12752).
