AsterX: a new open-source GPU-accelerated GRMHD code for dynamical spacetimes
Jay V. Kalinani, Liwei Ji, Lorenzo Ennoggi +10
We present AsterX, a novel open-source, modular, GPU-accelerated, fully general relativistic magnetohydrodynamic (GRMHD) code designed for dynamic spacetimes in 3D Cartesian coordi…
First results of the glitching pulsars monitoring program at the Argentine Institute of Radioastronomy
Ezequiel Zubieta, Ryan Missel, Valentina Sosa Fiscella +10
We report here on the first results of a systematic monitoring of southern glitching pulsars at the Argentine Institute of Radioastronomy that started in the year 2019. We detected…
Handing off the outcome of binary neutron star mergers for accurate and long-term post-merger simulations
Federico G. Lopez Armengol, Zachariah B. Etienne, Scott C. Noble +20
We perform binary neutron star (BNS) merger simulations in full dynamical general relativity with IllinoisGRMHD, on a Cartesian grid with adaptive-mesh refinement. After the remnan…
Electromagnetic Signatures from Supermassive Binary Black Holes Approaching Merger
Eduardo M. Gutiérrez, Luciano Combi, Scott C. Noble +4
We present fully relativistic predictions for the electromagnetic emission produced by accretion disks surrounding spinning and nonspinning supermassive binary black holes on the v…
Mini-disk accretion onto spinning black hole binaries: quasi-periodicities and outflows
Luciano Combi, Federico G. Lopez Armengol, Manuela Campanelli +4
We perform a full 3D general relativistic magnetohydrodynamical (GRMHD) simulation of an equal-mass, spinning, binary black hole approaching merger, surrounded by a circumbinary di…
Vela Pulsar: Single Pulses Analysis with Machine Learning Techniques
Carlos O. Lousto, Ryan Missel, Harsh Prajapati +12
We study individual pulses of Vela (PSR\ B0833-45\,/\,J0835-4510) from daily observations of over three hours (around 120,000 pulses per observation), performed simultaneously with…
HARM3D+NUC: A new method for simulating the post-merger phase of binary neutron star mergers with GRMHD, tabulated EOS and neutrino leakage
Ariadna Murguia-Berthier, Scott C. Noble, Luke F. Roberts +25
The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component p…
Effects of Scalar-Tensor-Vector Gravity on relativistic jets
Federico G. Lopez Armengol, Gustavo E. Romero
Scalar-Tensor-Vector Gravity (STVG) is a theory that does not require dark components to describe astrophysical data. We aim at constraining the free parameters of STVG based on re…
