EP250302a: violent shell collision in a soft-X-ray-selected GRB-like transient
Shao-Yu Fu, Cui-Yuan Dai, Ai-Ling Wang +57
The Einstein Probe opens a previously unexplored soft X-ray window onto gamma-ray bursts, filling a critical observational gap in the soft X-ray coverage of their prompt emission.…
The Cosmological Population of Gamma-Ray Bursts from the Disks of Active Galactic Nuclei
Hoyoung D. Kang, Rosalba Perna, Davide Lazzati +1
With the discovery of gravitational waves (GWs), Active Galactic Nuclei (AGN) disks have emerged as an interesting environment for hosting a fraction of their sources. AGN disks ar…
Stellar/BH Population in AGN Disks: Direct Binary Formation from Capture Objects in Nuclei Clusters
Yihan Wang, Zhaohuan Zhu, Douglas N. C. Lin
The Active Galatic Nuclei(AGN) disk has been proposed as a potential channel for the merger of binary black holes. The population of massive stars and black holes in AGN disks capt…
Tidal Peeling Events: low-eccentricity tidal disruption of a star by a stellar-mass black hole
Chengcheng Xin, Zoltan Haiman, Rosalba Perna +2
Close encounters between stellar-mass black holes (BHs) and stars occur frequently in dense star clusters and in the disks of active galactic nuclei (AGNs). Recent studies have sho…
Effective two-body scatterings around a massive object
Yihan Wang, Saavik Ford, Rosalba Perna +3
Two-body scatterings under the potential of a massive object are very common in astrophysics. If the massive body is far enough away that the two small bodies are in their own grav…
Close Encounters of Stars with Stellar-mass Black Hole Binaries
Taeho Ryu, Rosalba Perna, Yihan Wang
Many astrophysical environments, from star clusters and globular clusters to the disks of Active Galactic Nuclei, are characterized by frequent interactions between stars and the c…
The emergence of diffused Gamma-Ray Burst afterglows from the disks of Active Galactic Nuclei
Yihan Wang, Davide Lazzati, Rosalba Perna
The disks of Active Galactic Nuclei (AGNs) have emerged as rich environments for the production and capture of stars and the compact objects that they leave behind. These stars pro…
Host galaxies and electromagnetic counterparts to binary neutron star mergers across the cosmic time: Detectability of GW170817-like events
Rosalba Perna, M. Celeste Artale, Yi-Han Wang +4
The detection of electromagnetic radiation (EM) accompanying the gravitational wave (GW) signal from the binary neutron star (BNS) merger GW170817 has revealed that these systems c…
Symmetry Breaking in Dynamical Encounters in the Disks of Active Galactic Nuclei
Yihan Wang, Barry McKernan, Saavik Ford +3
Active galactic nucleus (AGN) disks may be important sites of binary black hole (BBH) mergers. Here we show via numerical experiments with the high-accuracy, high precision code {\…
Hot Jupiter formation in dense clusters: secular chaos in multi-planetary systems
Yihan Wang, Rosalba Perna, Nathan W. C. Leigh +1
Exoplanetary observations reveal that the occurrence rate of hot Jupiters is correlated with star clustering. In star clusters, interactions between planetary systems and close fly…
SpaceHub: A high-performance gravity integration toolkit for few-body problems in astrophysics
Yi-Han Wang, Nathan Leigh, Bin Liu +1
We present the open source few-body gravity integration toolkit {\tt SpaceHub}. {\tt SpaceHub} offers a variety of algorithmic methods, including the unique algorithms AR-Radau, AR…
Partial tidal disruption events by stellar mass black holes: gravitational instability of stream and impact from remnant core
Yi-Han Wang, Rosalba Perna, Philip J. Armitage
In dense star clusters, such as globular and open clusters, dynamical interactions between stars and black holes (BHs) can be extremely frequent, leading to various astrophysical t…
Hot Jupiter and ultra-cold Saturn formation in dense star clusters
Yi-Han Wang, Nathan W. C. Leigh, Rosalba Perna +1
The discovery of high incidence of hot Jupiters in dense clusters challenges the field-based hot Jupiter formation theory. In dense clusters, interactions between planetary systems…

Yi-Han Wang, Rosalba Perna, Nathan W. C. Leigh
The discovery of planetary systems outside of the solar system has challenged some of the tenets of planetary formation. Among the difficult-to-explain observations, are systems wi…
Planetary Architectures in Interacting Stellar Environments
Yi-Han Wang, Rosalba Perna, Nathan W. C. Leigh
The discovery of Exoplanetary Systems has challenged some of the theories of planet formation, which assume unperturbed evolution of the host star and its planets. However, in star…
