A 14-year-old Mystery: The Peculiar Case of the Engine-driven SN 2012ap

Itai Sfaradi, Raffaella Margutti, Ryan Chornock +29

We present late-time ( d) optical (Keck), X-ray (Chandra and NuSTAR), and radio (VLA, ALMA, and the uGMRT) observations of the Type Ic-BL SN 2012ap. Previous studies of…

Evolution of Extremely Soft Binaries in Dense Star Clusters: On the Jupiter Mass Binary Objects

Yihan Wang, Rosalba Perna, Zhaohuan Zhu +1

Star-forming regions, characterized by dense environments, experience frequent encounters that significantly influence binary systems, leading to their hardening, softening, or ion…

Conditions for Changing-Look AGNs from Accretion Disk-Induced Tidal Disruption Events

Yihan Wang, Matthew J. Graham, K. E. Saavik Ford +3

The phenomenon of changing-look (CL) behavior in active galactic nuclei (AGN) is characterized by dramatic changes in luminosity and/or emission line profiles over relatively short…

Evidence of a Past Merger of the Galactic Center Black Hole

Yihan Wang, Bing Zhang

The origin of supermassive black holes (SMBHs) residing in the centers of most galaxies remains a mystery. The Event Horizon Telescope (EHT) provided direct imaging of the SMBH Sgr…

Floating binary planets from ejections during close stellar encounters

Yihan Wang, Rosalba Perna, Zhaohuan Zhu

The discovery of planetary systems beyond our solar system has challenged established theories of planetary formation. Planetary orbits display a variety of unexpected architecture…

Tidal Disruption Events from three-body scatterings and eccentricity pumping in the disks of Active Galactic Nuclei

Chaitanya Prasad, Yihan Wang, Rosalba Perna +2

Tidal Disruption Events (TDEs) are routinely observed in quiescent galaxies, as stars from the nuclear star cluster are scattered into the loss cone of the central supermassive bla…
