Transient fading X-ray emission detected during the optical rise of a tidal disruption event

Transient fading X-ray emission detected during the optical rise of a tidal disruption event

We report on the SRG/eROSITA detection of ultra-soft (kT = 47+−55 eV) X-ray emission (LX =2.5+−00.56 × 1043 erg s−1) from the tidal disruption event (TDE) candidate AT 2022dsb ∼14 d before peak optical brightness. As the optical luminosity increases after the eROSITA detection, then the 0.2–2 keV ob...
