NICER observations of late-time X-ray brightening of the tidal disruption event candidate AT2019azh
Abstract
The transient AT2019azh was discovered on 2019 February 22 by the ASASSN sky survey. Spatial coincidence with the nucleus of a galaxy at redshift of 0.022 combined with the blue optical spectrum (ATel#12529) suggested the source could be a tidal disruption event (TDE) candidate (ATel#12568, #12870).
