The Origin of the Magnetic Flux Driving TDE Jets
Nimrod Tripto, Julian Krolik, Tsvi Piran
Tidal Disruption Events (TDEs) occur when a star approaches a black hole closely enough to be torn apart by tidal forces, after which the stellar debris begins to orbit the black h…
Simulation-Based Prediction of Black Hole Fe K Line Profiles
Chris Nagele, Julian H. Krolik, Brooks E. Kinch +1
One of the most useful spectral diagnostics of accreting black hole systems is the Fe K fluorescence line. Detected in many systems, it is often used to estimate the black hole…
Unexpectedly Weak General Relativistic Effects in Strongly Relativistic Tidal Disruption Events
Ho-Sang Chan, Taeho Ryu, Julian Krolik +1
Tidal disruption events (TDEs) occur when stars are destroyed by supermassive black holes and are among the brightest nuclear transients. It has been thought that strong relativist…
Simulation-Based Prediction of Black Hole Spectra: From to
Chris Nagele, Julian H. Krolik, Rongrong Liu +2
It has long been thought that black hole accretion flows are driven by magnetohydrodynamic (MHD) turbulence, and there are now many general relativistic global simulations illustra…
The TDE Population from First-Principles Models of Stellar Disruption and Debris Dynamics
Tsvi Piran, Julian Krolik, Taeho Ryu
We present a physically-grounded population model for optical tidal disruption events (TDEs) that combines first-principles hydrodynamic simulations of stellar disruption with stat…
The merger of spinning, accreting supermassive black hole binaries
Lorenzo Ennoggi, Manuela Campanelli, Julian Krolik +3
Because they are likely to accrete substantial amounts of interstellar gas, merging supermassive binary black holes are expected to be strong multimessenger sources, radiating grav…
