Early Near-Infrared Excess and Rapid Disk-Corona Evolution in the Tidal Disruption Event 2024aepd

Yongxin Wu, Yanan Wang, Thomas M. Reynolds +38

We present multi-wavelength observations of the tidal disruption event (TDE) 2024aepd, spanning primarily the first 300 days after discovery. A prominent near-infrared (NIR)…

Unveiling the nature of G6096: a likely hierarchical triple system

Yinghao Xu, Xinlin Zhao, Song Wang +10

G6096 (Gaia DR3 609651611028044544) was recently reported as a wide ( days) and eccentric () binary possibly hosting a massive white dwarf or neutron star. In…

The X-ray Variability of the Ultraluminous X-ray Sources in the NGC 4631 galaxy

Jiashun Chen, Jianfeng Wu, Zikun Lin

We perform a systematic study on the long-term X-ray variability for the five ultraluminous X-ray sources (ULXs) in the NGC 4631 galaxy (X1-X5), using Chandra, XMM-Newton, and Swif…

Radiation hydrodynamic simulations for the origin of quasi-periodic oscillations for accretion onto supermassive black holes

Yiyang Lin, Erlin Qiao, Jifeng Liu +2

Quasi-periodic oscillation (QPO) has been detected in several accreting supermassive black hole (SMBH) systems, including active galactic nuclei (AGNs) and tidal disruption events…

Detection of disk-jet co-precession in a tidal disruption event

Yanan Wang, Zikun Lin, Linhui Wu +46

Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…

IGR J17091-3624: Newly Formed Periodic Dips and Multiwavelength Activity During the 2025 Outburst

Zikun Lin, Yanan Wang, Shuyuan Wei +15

The black hole low-mass X-ray binary (LMXB) candidate IGR J17091-3624 experienced a hard-state-only outburst in 2025. In this paper, we show that IXPE detected a series of intermit…

Delayed Launch of Ultrafast Outflows in the Tidal Disruption Event AT2020afhd

Zikun Lin, Yanan Wang, De-Fu Bu +2

We report the detection and characterization of ultrafast outflows (UFOs) in the X-ray spectra of the tidal disruption event (TDE) AT2020afhd, based on observations from NICER, Swi…

Unraveling the hybrid origins of the X-ray non-thermal emission from IGR J17091-3624

Zikun Lin, Yanan Wang, Santiago del Palacio +8

We present a comprehensive study based on multi-wavelength observations from the NuSTAR, NICER, Swift, Fermi, NEOWISE, and ATCA telescopes during the 2022 outburst of the black hol…
