Implications of the UV/optical Plateau of AT2018cow
Wenbin Lu, Anthony L. Piro
AT2018cow, the prototypical luminous fast blue optical transient (LFBOT), shows a slowly fading plateau in the UV/optical light lasting at least 5 years after the explosion. The pl…

Star-Disk Collisions: Implications for Quasi-periodic Eruptions and Other Transients Near Supermassive Black Holes
Philippe Z. Yao, Eliot Quataert, Yan-Fei Jiang +2
We use Athena++ to study the hydrodynamics of repeated star-accretion disk collisions close to supermassive black holes, and discuss their implications for the origin of quasi-peri…
