资源简介:

In a search for new TDEs candidates we crossmatched optical and xrayscatalogues. We propose the observation of 5 of our best candidates\\: thesegalaxies show a high xrays luminosity (L_X>10^41 erg/sec) and an extremely softspectrum (Gamma>3) in the same energy band. As no other known source should beable to show a similar behaviour we are positive that these are unrecognizedTDEs. If these galaxies indeed hosted a TDE we expect that by now theirluminosity should have dropped by a significant factor (>5) allowing us toconfirm their nature. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
