SPROUT: A moving mesh hydro code using a uniformly expanding Cartesian grid
Soham Mandal, Paul C. Duffell
We present the publicly available moving-mesh hydrodynamics code Sprout. Sprout solves the equations of ideal hydrodynamics on an expanding Cartesian mesh. The expanding mesh can f…
Hydrodynamic mixing of accretion disk outflows in collapsars: implications for r-process signatures
Jennifer Barnes, Paul C. Duffell
The astrophysical environments capable of triggering heavy-element synthesis via rapid neutron capture (the r-process) remain uncertain. While binary neutron star mergers (NSMs) ar…
A 3D Numerical Study of Anisotropies in Supernova Remnants
Soham Mandal, Paul C. Duffell, Abigail Polin +1
We develop a suite of 3D hydrodynamic models of supernova remnants (SNRs) expanding against the circumstellar medium (CSM). We study the Rayleigh-Taylor Instability (RTI) forming a…
The Radio to GeV Afterglow of GRB 221009A
Tanmoy Laskar, Kate D. Alexander, Raffaella Margutti +27
GRB 221009A () is one of the closest known long -ray bursts (GRBs). Its extreme brightness across all electromagnetic wavelengths provides an unprecedented opportunity…
Scary Barbie: An Extremely Energetic, Long-Duration Tidal Disruption Event Candidate Without a Detected Host Galaxy at z = 0.995
Bhagya M. Subrayan, Dan Milisavljevic, Ryan Chornock +19
We report multi-wavelength observations and characterization of the ultraluminous transient AT 2021lwx (ZTF20abrbeie; aka ``Barbie'') identified in the alert stream of the Zwicky T…
