Looking for QPO candidates among luminous super-soft X-ray sources

We propose the observation of two hyperluminous extragalactic sources withpossible quasiperiodic variability, belonging to a sample of virgul40 super softXray sources we recently discovered. The luminosity and temperature of theobjects in this sample is larger than 10^41 erg/s and around 60100 eV,respectively, making them either Tidal Disruption Event candidates, orIntermediate Mass Black Hole candidates. We propose the observation of 2 of themost extreme sources for which we have a single observation showing hints ofshortterm variability. Our goal is to check their shortterm lightcurves forQPOs and their longterm one in order to confirm or exclude their TDE nature. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
