An Intermediate-mass Black Hole Lurking in A Galactic Halo Caught Alive during Outburst
C. -C. Jin, D. -Y. Li, N. Jiang +137
Stellar-mass and supermassive black holes abound in the Universe, whereas intermediate-mass black holes (IMBHs) of ~10^2-10^5 solar masses in between are largely missing observatio…
Absence of the predicted 2022 October outburst of OJ 287 and implications for binary SMBH scenarios
S. Komossa, D. Grupe, A. Kraus +9
The project MOMO (Multiwavelength Observations and Modelling of OJ 287) was set up to test predictions of binary supermassive black hole (SMBH) scenarios and to understand disk-jet…
MOMO VI: Multifrequency radio variability of the blazar OJ 287 from 2015-2022, absence of predicted 2021 precursor-flare activity, and a new binary interpretation of the 2016/2017 outburst
S. Komossa, A. Kraus, D. Grupe +12
Based on our dedicated Swift monitoring program, MOMO, OJ 287 is one of the best-monitored blazars in the X-ray--UV--optical regime. Here, we report results from our accompanying,…
Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: An Multi-mass Direct N-body Model
Shuo Li, Shiyan Zhong, Peter Berczik +3
By using direct N-body numerical simulations, we model the dynamical co-evolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to…
Milli-Hertz Gravitational Wave Background Produced by Quasi-Periodic Eruptions
Xian Chen, Yu Qiu, Shuo Li +1
Extreme-mass-ratio inspirals (EMRIs) are important targets for future space-borne gravitational-wave (GW) detectors, such as the Laser Interferometer Sapce Antenna (LISA). Recent w…
Measuring black hole masses from tidal disruption events and testing the relation
Z. Q. Zhou, F. K. Liu, S. Komossa +4
Liu and collaborators recently proposed an elliptical accretion disk model for tidal disruption events (TDEs). They showed that the accretion disks of optical/UV TDEs are large and…
A large accretion disk of extreme eccentricity in the TDE ASASSN-14li
R. Cao, F. K. Liu, Z. Q. Zhou +2
In the canonical model for tidal disruption events (TDEs), the stellar debris circularizes quickly to form an accretion disk of size about twice the orbital pericenter of the star.…
Disk origin of broad optical emission lines of the TDE candidate PTF09djl
F. K. Liu, Z. Q. Zhou, R. Cao +2
An otherwise dormant supermassive black hole (SMBH) in a galactic nucleus flares up when it tidally disrupts a star passing by. Most of the tidal disruption events (TDEs) and candi…
A milliparsec supermassive black hole binary candidate in the galaxy SDSS J120136.02+300305.5
F. K. Liu, Shuo Li, S. Komossa
Galaxy mergers play a key role in the evolution of galaxies and the growth of their central supermassive black holes (SMBHs). A search for (active) SMBH binaries (SMBHBs) at the ce…
Interruption of Tidal Disruption Flares By Supermassive Black Hole Binaries
F. K. Liu, S. Li, Xian Chen
Supermassive black hole binaries (SMBHBs) are products of galaxy mergers, and are important in testing Lambda cold dark matter cosmology and locating gravitational-wave-radiation s…
