Too Quiet for Comfort: Local Little Red Dots Lack Variability over Decades
Colin J. Burke, Zachary Stone, Yue Shen +1
Several local () metal-poor dwarf AGNs have remarkably similar properties to those of high-redshift Little Red Dots (LRDs), and are recently proposed to be local ana…
Radiation Magnetohydrodynamic Simulation of sub-Eddington Circumbinary Disk in a 10:1 Massive Black Hole Binary
Vishal Tiwari, Chi-Ho Chan, Tamara Bogdanović +2
We present a global three-dimensional radiation magnetohydrodynamic (RMHD) simulation of a circumbinary disk (CBD) around a massive black hole binary (MBHB) with a total mass $2 \t…
: Self-Sustained Streaming Motions in Multi-Phase MHD
Chaoran Wang, S. Peng Oh, Yan-Fei Jiang +1
Radiative cooling can drive dynamics in multi-phase gas. A dramatic example is hydrodynamic `shattering', the violent, pressure-driven fragmentation of a cooling cloud which falls…
Simulating X-ray Reverberation in the UV-Emitting Regions of Active Galactic Nuclei Accretion Disks with 3D Multi-Frequency Magnetohydrodynamic Simulations
Amy Secunda, Yan-Fei Jiang, Jenny E. Greene
Active galactic nuclei (AGN) light curves observed with different wavebands show that the variability in longer wavelength bands lags the variability in shorter wavelength bands. M…
Negative Lags on the Viscous Timescale in Quasar Photometry and Prospects for Detecting More with LSST
Amy Secunda, Jenny E. Greene, Yan-Fei Jiang +2
The variability of quasar light curves can be used to study the structure of quasar accretion disks. For example, continuum reverberation mapping uses delays between variability in…
A New Numerical Scheme for Cosmic Ray Transport
Yan-Fei Jiang, Peng Oh
Numerical solutions of the cosmic-ray (CR) magneto-hydrodynamic equations are dogged by a powerful numerical instability, which arises from the constraint that CRs can only stream…
Detection of Time Lags Between Quasar Continuum Emission Bands based on Pan-STARRS Light-curves
Yan-Fei Jiang, Paul J. Green, Jenny E. Greene +21
We study the time lags between the continuum emission of quasars at different wavelengths, based on more than four years of multi-band (, , , ) light-curves in the Pan-…
