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…
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…
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 {\…
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…
Binary Mergers near a Supermassive Black Hole: Relativistic Effects in Triples
Bin Liu, Dong Lai, Yi-Han Wang
We study the general relativitic (GR) effects induced by a spinning supermassive black hole on the orbital and spin evolution of a merging black hole binary (BHB) in a hierarchical…
Black Hole and Neutron Star Binary Mergers in Triple Systems: II. Merger Eccentricity and Spin-Orbit Misalignment
Bin Liu, Dong Lai, Yi-Han Wang
We study the dynamical signatures of black hole (BH) and neutron star (NS) binary mergers via Lidov-Kozai oscillations induced by tertiary companions in hierarchical triple systems…
Multi-Messenger Astronomy with Extremely Large Telescopes
Ryan Chornock, Philip S. Cowperthwaite, Raffaella Margutti +82
The field of time-domain astrophysics has entered the era of Multi-messenger Astronomy (MMA). One key science goal for the next decade (and beyond) will be to characterize gravitat…
Constraining the Black Hole Initial Mass Function with LIGO/VIRGO Observations
Rosalba Perna, Yi-Han Wang, Will M. Farr +2
Prior to the detection of black holes (BHs) via the gravitational waves (GWs) they generate at merger, the presence of BHs was inferred in X-ray binaries, mostly via dynamical meas…
