An Extension of the Athena++ Code Framework for Radiation-Magnetohydrodynamics in General Relativity Using a Finite-Solid-Angle Discretization
Christopher J. White, Patrick D. Mullen, Yan-Fei Jiang +4
We extend the general-relativistic magnetohydrodynamics (GRMHD) capabilities of Athena++ to incorporate radiation. The intensity field in each finite-volume cell is discretized in…
Modeling the light curve of Type IIn-P SN 2005cl with red supergiant progenitors featuring pre-SN ourbursts
Chunhui Li, Viktoriya Morozova
All Type IIn supernovae (SNe IIn) show narrow hydrogen emission lines in their spectra. Apart from this common feature, they demonstrate very broad diversity in brightness, duratio…
Progenitor and Close-In Circumstellar Medium of Type II Supernova 2020fqv from High-Cadence Photometry and Ultra-Rapid UV Spectroscopy
Samaporn Tinyanont, Ryan Ridden-Harper, Ryan Foley +35
We present observations of SN 2020fqv, a Virgo-cluster Type II core-collapse supernova (CCSN) with a high temporal resolution light curve from the Transiting Exoplanet Survey Satel…
GRAthena++: puncture evolutions on vertex-centered oct-tree AMR
Boris Daszuta, Francesco Zappa, William Cook +3
Numerical relativity is central to the investigation of astrophysical sources in the dynamical and strong-field gravity regime, such as binary black hole and neutron star coalescen…
The influence of late-stage nuclear burning on red supergiant supernova light curves
Viktoriya Morozova, Anthony L. Piro, Jim Fuller +1
Many Type II supernovae (SNe) show hot early (~30 days) emission, and a diversity in their light curves extending from the Type IIP to the Type IIL, which can be explained by inter…
Constraining properties of the next nearby core-collapse supernova with multi-messenger signals
MacKenzie L. Warren, Sean M. Couch, Evan P. O'Connor +1
With the advent of modern neutrino and gravitational wave detectors, the promise of multi-messenger detections of the next galactic core-collapse supernova has become very real. Su…
