Unlocking the QPE Mystery: Star-Disk Collisions in Realistic AGN Disks
Zhaohuan Zhu, Xiaoshan Huang, Yan-Fei Jiang +1
Quasi-periodic eruptions (QPEs) are luminous, recurring soft X-ray outbursts observed in the nuclei of low-mass galaxies. They display two remarkable trends: outburst durations are…
Stellar mergers and chemical element mixing: implications for the metamorphic stellar evolution in AGN disks
Yanlong Shi, Xiaoshan Huang, Douglas N. C. Lin +1
Chemical mixing during stellar mergers can significantly influence the subsequent evolution of the merger remnant. We perform a suite of three-dimensional hydrodynamical simulation…
The Light Curve of Wind-Reprocessed Tidal Disruption Events
Brenna Mockler, David Khatami, Daniel Kasen +2
The source of the optical/UV emission in tidal disruption events (TDEs) remains an enduring question in the field. Connecting the observed emission to the source is critical for bo…
Resolving Oblique Star-Disk Collisions in Quasi-Periodic Eruptions: Numerical Requirements and the Importance of Geometry
Shunquan Huang, Xiaoshan Huang, Zhaohuan Zhu +1
Star-disk collisions have been proposed as a promising mechanism for producing quasi-periodic eruptions (QPEs) in galactic nuclei. Because the stellar atmospheric scale height is o…
AT2024lhc and AT2024kmq in the landscape of featureless tidal disruption events
Yuhan Yao, Ryan Chornock, Andrew Mummery +39
We study AT2024kmq and AT2024lhc, two tidal disruption events (TDEs) with blue featureless spectra associated with high-mass black holes (). Both even…
X-ray Variability and Photosphere Evolution during Accretion Disk Formation in Tidal Disruption Events
Xiaoshan Huang, Maria Renee Meza, Sol Bin Yun +3
The early time emission in tidal disruption events (TDEs) originates from both accretion and shocks, producing photons that eventually emerge from an inhomogeneous photosphere. We…
The Most Luminous Known Fast Blue Optical Transient AT 2024wpp: Unprecedented Evolution and Properties in the X-rays and Radio
A. J. Nayana, Raffaella Margutti, Eli Wiston +34
We present X-ray (0.3--79 keV) and radio (0.25--203 GHz) observations of the most luminous Fast Blue Optical Transient (LFBOT) AT\,2024wpp at , spanning 2--280 days after…
Perturbing AGN Accretion Disks with Stars and Moderately Massive Black Holes: Implications for Changing-Look AGN and Quasi-Periodic Eruptions
Sierra A. Dodd, Xiaoshan Huang, Shane W. Davis +1
We present a model that explains some extreme variability phenomena observed in active galactic nuclei (AGN). In this model, an orbiting companion interacts with the accretion disk…
Disk draining in LIGO progenitor black hole binaries and its significance to electromagnetic counterparts
Xiaoshan Huang, Sierra Dodd, Sophie Lund Schrøder +2
The effect of tidal forces on transport within a relic accretion disk in binary black holes is studied here with a suite of two-dimensional hydrodynamic simulations. As the binary…
Transients by Black Hole Formation from Red Supergiants: Impact of Dense Circumstellar Matter
Daichi Tsuna, Xiaoshan Huang, Jim Fuller +1
Failed supernovae (SNe), which are likely the main channel for forming stellar-mass black holes, are predicted to accompany mass ejections much weaker than typical core-collapse SN…
Pre-peak Emission in Tidal Disruption Events
Xiaoshan Huang, Shane W. Davis, Yan-fei Jiang
The rising part of a tidal disruption event light curve provides unique insight into early emission and the onset of accretion. Various mechanisms are proposed to explain the pre-p…
A Bright First Day for Tidal Disruption Event
Xiaoshan Huang, Shane W. Davis, Yan-fei Jiang
Stream-stream collision may be an important pre-peak energy dissipation mechanism in tidal disruption events (TDEs). We perform local three-dimensional radiation hydrodynamic simul…
CR Driven Multi-phase Gas Formed via Thermal Instability
Xiaoshan Huang, Yan-fei Jiang, Shane W. Davis
Cosmic rays (CRs) are an important energy source in the circum-galactic medium (CGM) that impact the multi-phase gas structure and dynamics. We perform two-dimensional CR-magnetohy…
The Launching of Cosmic Ray Driven Outflows
Xiaoshan Huang, Shane W. Davis
Cosmic rays (CRs) are thought to be an important feedback mechanism in star-forming galaxies. They can provide an important source of pressure support and possibly drive outflows.…
