Multigroup Radiation Diffusion on a Moving Mesh: Implementation in RICH and Application to Tidal Disruption Events
Itamar Giron, Menahem Krief, Nicholas C. Stone +1
Radiation-hydrodynamics (RHD) determines the bulk evolution and observable emission in a wide variety of high-energy astrophysical phenomena. Due to their complexity, RHD problems…
Boson Cloud Atlas: Direct mass measurements of superradiance clouds near black holes
Majed Khalaf, Eric Kuflik, Alessandro Lenoci +1
Ultralight scalars emerge naturally in several motivated particle physics scenarios and are viable candidates for dark matter. While laboratory detection of such bosons is challeng…
Mean Motion Resonances in AGN Disks
Marguerite Epstein-Martin, Nicholas Stone, Juliette Becker
Mean motion resonances (MMRs) are a generic outcome of convergent migration for bodies embedded in accretion disks around a central mass. Long studied in planetary systems, the sam…
The intermediate-mass black hole 2XMM J123103.2+110648: a varying disc accretion rate during possible X-ray quasi-periodic eruptions?
Z. Cao, P. G. Jonker, S. Wen +2
We fit the evolving X-ray spectra of the variable and fading source 2XMM J123103.2+110648 (J1231), which is an intermediate-mass black hole (IMBH) candidate. Recent X-ray timing st…
