General-relativistic radiation magnetohydrodynamics simulations of binary neutron star mergers: The influence of spin on the multi-messenger picture
Anna Neuweiler, Henrique Gieg, Henrik Rose +8
The rich phenomenology of binary neutron star mergers offers a unique opportunity to test general relativity, investigate matter at supranuclear densities, and learn more about the…
Multi-physics framework for fast modeling of gamma-ray burst afterglows
Vsevolod Nedora, Ludovica Crosato Menegazzi, Enrico Peretti +2
In this paper, we present PyBlastAfterglow, a modular C++ code with a Python interface to model light curves and sky maps of gamma-ray burst afterglows. The code is open-source, mo…
Multi-band analyses of the bright GRB 230812B and the associated SN2023pel
T. Hussenot-Desenonges, T. Wouters, N. Guessoum +109
GRB~230812B is a bright and relatively nearby () long gamma-ray burst (GRB) that has generated significant interest in the community and has thus been observed over the en…
Chemical Distribution of the Dynamical Ejecta in the Neutron Star Merger GW170817
Shreya Anand, Peter T. H. Pang, Mattia Bulla +11
GW170817 and its associated electromagnetic counterpart AT2017gfo continue to be a treasure trove as observations and modeling continue. Recent precision astrometry of AT2017gfo wi…
M1 neutrino transport within the numerical-relativistic code BAM with application to low mass binary neutron star mergers
Federico Schianchi, Henrique Gieg, Vsevolod Nedora +4
Neutrino interactions are essential for an accurate understanding of the binary neutron star merger process. In this article, we extend the code infrastructure of the well-establis…
GRANDMA and HXMT Observations of GRB 221009A -- the Standard-Luminosity Afterglow of a Hyper-Luminous Gamma-Ray Burst
D. A. Kann, S. Agayeva, V. Aivazyan +113
GRB 221009A is the brightest Gamma-Ray Burst (GRB) detected in more than 50 years of study. In this paper, we present observations in the X-ray and optical domains after the GRB ob…
Synthetic radio images of structured GRB and kilonova afterglows
Vsevolod Nedora, Tim Dietrich, Masaru Shibata
In this paper, we compute and analyze synthetic radio images of gamma-ray bursts and kilonova afterglows. For modeling the former, we consider GRB170817A-inspired set of parameters…
Bayesian model selection for GRB 211211A through multi-wavelength analyses
Nina Kunert, Sarah Antier, Vsevolod Nedora +12
Although GRB 211211A is one of the closest gamma-ray bursts (GRBs), its classification is challenging because of its partially inconclusive electromagnetic signatures. In this pape…
Modeling kilonova afterglows: Effects of the thermal electron population and interaction with GRB outflows
Vsevolod Nedora, Tim Dietrich, Masaru Shibata +2
Given an increasing number of gamma-ray bursts accompanied by potential kilonovae there is a growing importance to advance modelling of kilonova afterglows. In this work, we invest…
An updated nuclear-physics and multi-messenger astrophysics framework for binary neutron star mergers
Peter T. H. Pang, Tim Dietrich, Michael W. Coughlin +18
The multi-messenger detection of the gravitational-wave signal GW170817, the corresponding kilonova AT2017gfo and the short gamma-ray burst GRB170817A, as well as the observed afte…
Signatures of deconfined quark phases in binary neutron star mergers
Aviral Prakash, David Radice, Domenico Logoteta +6
(abridged) We investigate the quark deconfinement phase transition in the context of binary neutron star (BNS) mergers. We employ a new finite-temperature composition-dependent equ…
