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…
Black Hole - Neutron Star mergers: using kilonovae to constrain the equation of state
Lowri Wyn Prys Mathias, Francesco Di Clemente, Mattia Bulla +1
The merging of a binary system involving two neutron stars (NSs), or a black hole (BH) and a NS, often results in the emission of an electromagnetic (EM) transient. One component o…
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…
Optimising the observation of optical kilonovae with medium size telescopes
A. E. Camisasca, I. A. Steele, M. Bulla +2
We consider the optimisation of the observing strategy (cadence, exposure time and filter choice) using medium size (2-m class) optical telescopes in the follow-up of kilonovae loc…
JWST detection of heavy neutron capture elements in a compact object merger
A. Levan, B. P. Gompertz, O. S. Salafia +80
The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray burs…
Enabling Kilonova Science with Nancy Grace Roman Space Telescope
Igor Andreoni, Michael W. Coughlin, Alexander W. Criswell +16
Binary neutron star mergers and neutron star-black hole mergers are multi-messenger sources that can be detected in gravitational waves and in electromagnetic radiation. The low el…
Science with a small two-band UV-photometry mission I: Mission description and follow-up observations of stellar transients
N. Werner, J. Řípa, C. Thöne +33
This is the first in a collection of three papers introducing the science with an ultra-violet (UV) space telescope on an approximately 130~kg small satellite with a moderately fas…
SN 2020udy: a SN Iax with strict limits on interaction consistent with a helium-star companion
Kate Maguire, Mark R. Magee, Giorgos Leloudas +24
Early observations of transient explosions can provide vital clues to their progenitor origins. In this paper we present the nearby Type Iax (02cx-like) supernova (SN), SN 2020udy…
Early-time spectroscopic modelling of the transitional Type Ia Supernova 2021rhu with TARDIS
Luke Harvey, Kate Maguire, Mark R. Magee +15
An open question in SN Ia research is where the boundary lies between 'normal' Type Ia supernovae (SNe Ia) that are used in cosmological measurements and those that sit off the Phi…
General-Relativistic Hydrodynamics Simulation of a Neutron Star - Sub-Solar-Mass Black Hole Merger
Ivan Markin, Anna Neuweiler, Adrian Abac +4
Over the last few years, there has been an increasing interest in sub-solar mass black holes due to their potential to provide valuable information about cosmology or the black hol…
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…
Impact of jets on kilonova photometric and polarimetric emission from binary neutron star mergers
Manisha Shrestha, Mattia Bulla, Lorenzo Nativi +3
A merger of binary neutron stars creates heavy unstable elements whose radioactive decay produces a thermal emission known as a kilonova. In this paper, we predict the photometric…
Linear and circular polarimetry of the optically bright relativistic Tidal Disruption Event AT 2022cmc
Aleksandar Cikota, Giorgos Leloudas, Mattia Bulla +3
Tidal disruption events (TDEs) occur when a star orbiting a massive black hole is sufficiently close to be tidally ripped apart by the black hole. AT 2022cmc is the first relativis…
Polarimetry of Hydrogen-Poor Superluminous Supernovae
M. Pursiainen, G. Leloudas, A. Cikota +11
We present linear polarimetry for seven hydrogen-poor superluminous supernovae (SLSNe-I). For SN 2017gci, for which we present two epochs of spectropolarimetry at +3 d and +29 d po…
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…
