Two Earliest Optical-UV Tidal Disruption Events Hidden in the SDSS DR7 Catalog Unveiled by the Transformer-Based Spectrum Classifier

Ranfang Zheng, Zheyu Lin, Xu Kong +3

Optical spectroscopic features are decisive in the current identification of optical-UV tidal disruption events (TDEs). Regarding that the TDE estimated occurrence rate is $10^{-5}…

Difference Between Half-mass Radius and Half-light Radius of Galaxies at 0.2 $< z <$ 2.5 Revealed by JWST/NIRCam Data

Mingen Xin, Guanwen Fang, Jie Song +3

Using JWST observations in CANDELS fields, we measure the half-light radius ( $r_{e, light}$ ) and half-mass radius ( $r_{e, mass}$ ) for 14,333 galaxies with stellar masses $M_*…
