Beta-Particle Transport and Thermalization in Kilonova Ejecta with Detailed Atomic Microphysics
Zachary L. Andalman, Christopher L. Fryer, Christopher J. Fontes +2
When two neutron stars collide, they eject material containing heavy nuclei formed by the rapid neutron capture process (-process). As these nuclei decay, they power a bright op…
On the origin of anomalous dissipation in simulations of tidal disruption events
Chris Nixon, Eric R. Coughlin, Zachary L. Andalman
In a tidal disruption event (TDE), a star is destroyed by the tidal field of a supermassive black hole. The stellar debris is initially placed on highly elliptical orbits, and a lo…
Resolving the (Debate About) Nozzle Shocks in Tidal Disruption Events
Zachary L. Andalman, Eliot Quataert, Eric R. Coughlin +1
When a star passes within the Roche limit of a supermassive black hole (SMBH), it is pulled apart by the BH's tidal field in a tidal disruption event (TDE). The resulting flare is…
Supermassive Black Hole Growth in Massive Galaxies at Cosmic Dawn
James Sunseri, Zachary L. Andalman, Romain Teyssier
Among the emerging excess of massive, bright galaxies at Cosmic Dawn seen by the James Webb Space Telescope, several exhibit spectral features associated with active…
On the Origin of the High Star-Formation Efficiency in Massive Galaxies at Cosmic Dawn
Zachary Lee Andalman, Romain Teyssier, Avishai Dekel
Motivated by the early excess of bright galaxies seen by JWST, we run zoom-in cosmological simulations of a massive galaxy at Cosmic Dawn, in a halo of at …
Nozzle Shocks, Disk Tearing and Streamers Drive Rapid Accretion in 3D GRMHD Simulations of Warped Thin Disks
Nicholas Kaaz, Matthew T. P. Liska, Jonatan Jacquemin-Ide +4
The angular momentum of gas feeding a black hole (BH) is typically misaligned with respect to the BH spin, resulting in a tilted accretion disk. Rotation of the BH drags the surrou…
