- W4283702805 abstract "We report a candidate tidal disruption event (TDE) found in the Zwicky Transient Facility (ZTF) survey data. This candidate, with its name ZTF18aawxosg, showed brightness increases of $sim$1,mag around MJD~59500 and subsequent power-law--like brightness declines. We have conducted multiple optical spectroscopic observations with the 2.4-m Lijiang telescope and one observation at X-ray and ultraviolet (UV) bands with the {it Neil Gehrels Swift Observatory (Swift)}. The optical spectra of the source show broad H and He emission lines and Fe emission features. No X-ray but bright UV emission of the source was detected. We analyze the declines of the optical light curves, the emission features of the optical spectra, and the constructed broadband spectrum with the UV flux measurement included. The derived properties are consistent with those of reported TDEs, thus strongly indicating this flare event as a candidate TDE belonging to the H+He class." @default.
