Relative frequencies of core-collapse supernovae as a function of metallicity: observations vs theoretical predictions
Claudia P. Gutiérrez, Lluís Galbany, Joseph P. Anderson +4
Understanding supernova (SN) progenitors remains a major challenge in astrophysics, as it involves untangling the complex interplay between stellar physics (e.g., evolution, binari…
Toward Black Hole Stars: supermassive black hole growth in nuclear clusters via stellar-object and gas accretion
Konstantinos Kritos, Joseph Silk
Supermassive black hole (SMBH) growth plausibly occurs via runaway astrophysical black hole mergers in nuclear star clusters that form intermediate mass black hole seeds at high re…
AGN in Gaia Alerts: from flares to Changing Look Quasars
M. Dennefeld, T. Pursimo, C. Carvalho +11
The Gaia Alerts system is providing alerts on a variety of objects displaying a significant photometric change detected by the Gaia satellite from one passage to the next one over…
Asymmetrical thermonuclear supernovae triggered by the tidal disruption of white dwarfs
Pavan Vynatheya, Luc Dessart, Taeho Ryu +1
In a dense star cluster core, a tidal disruption event (TDE) of a white dwarf (WD) can occur if the WD passes within the tidal radius of an intermediate-mass black hole (IMBH). Ver…
Minutes-long soft X-ray prompt emission from a compact object merger
An Li, Chen-Wei Wang, Niccolò Passaleva +75
Compact object mergers are multi-messenger sources and known progenitors of some gamma-ray bursts, bright flashes of high-energy radiation powered by a central engine, either an ac…
Probing millisecond magnetar formation in binary neutron star mergers through X-ray follow-up of gravitational wave alerts
Clara Plasse, Alexis Reboul-Salze, Jérome Guilet +5
The nature of the remnant of a binary neutron star (BNS) merger is uncertain. Though certainly a black hole (BH) in the cases of the most massive BNSs, X-ray lightcurves from gamma…
AT2024wpp: An Extremely Luminous Fast Ultraviolet Transient Powered by Accretion onto a Black Hole
Daniel A. Perley, Anna Y. Q. Ho, Zoë McGrath +69
We present the discovery of AT 2024wpp ("Whippet"), a fast and luminous 18cow-like transient. At a redshift of z=0.0868, revealed by Keck Cosmic Web Imager spectroscopy of its fain…
Probing the redshift evolution and sub-populations of binary neutron stars with the Einstein Telescope
Alexandre Toubiana, Irina Dvorkin
The formation channels of binary neutron stars (BNSs) currently remain uncertain, but important information can be gathered by observing their mergers with gravitational-wave detec…
Radiation-mediated shocks in gamma-ray bursts: spectral evolution
Filip Alamaa, Frédéric Daigne
Radiation-mediated shocks (RMSs) occurring below the photosphere in a gamma-ray burst (GRB) jet could play a crucial role in shaping the prompt emission. In this paper, we study th…
A Simulation Study on the Cosmic Ray Energy Spectra of Elemental Mass Groups using the Tibet Air Shower and Muon Detector Arrays through the Bayesian Unfolding Method
G. Imaizumi, M. Anzorena, K. Fujita +11
We study the analysis method to determine the cosmic-ray energy spectra of different mass groups assuming the use of the Tibet AS experiment, which consists of the high-density…
JWST reveals a supernova following a gamma-ray burst at z 7.3
A. J. Levan, B. Schneider, E. Le Floc'h +50
The majority of energetic long-duration gamma-ray bursts (GRBs) are thought to arise from the collapse of massive stars, making them powerful tracers of star formation across cosmi…
SVOM GRB 250314A at z 7.3: an exploding star in the era of reionization
B. Cordier, J. Y. Wei, N. R. Tanvir +103
Most long Gamma-ray bursts originate from a rare type of massive stellar explosion. Their afterglows, while rapidly fading, can be initially extremely luminous at optical/near-infr…
Diffuse gamma-ray and neutrino emission from the Milky Way and the local knee in the cosmic ray spectrum
C. Prevotat, Zh. Zhu, S. Koldobskiy +3
The LHAASO observatory has recently measured details of the cosmic-ray (CR) spectrum in the knee region (1 -- 10 PeV) with unprecedented precision, including its average CR mass co…
Gamma rays as leptonic portals to energetic neutrinos: a new Monte Carlo approach
Gaetano Di Marco, Rafael Alves Batista, Miguel A. Sánchez-Conde
High center-of-mass electromagnetic~(EM) interactions could produce decaying heavy leptons and hadrons, leading to neutrino generation. These processes might occur in the most extr…
CRPropa 3.3: Toward a Unified Multi-Messenger Framework from GeV to ZeV Energies

We present CRPropa 3.3, the latest release of the publicly available Monte Carlo framework for simulating the propagation of high-energy particles in astrophysical environments. Th…
Spectra for the Vacuum Cherenkov Effect in Astrophysical Electromagnetic Cascades with Lorentz Invariance Violation
Andrey Saveliev, Rafael Alves Batista, Feodor Mishin
Lorentz invariance violation is a feature of several quantum gravity models in which Lorentz symmetry is broken at high energies, possibly leading to changes in particle behavior a…
Effects of extragalactic magnetic field on the spectra of ultra-high-energy cosmic rays from jetted sources
Sarah Soares Sippert, Carlos Magno R. da Costa, Rogerio M. de Almeida +2
The origins and acceleration mechanisms of ultra-high-energy cosmic rays (UHECRs) are unknown. Many models attribute their extreme energies to powerful astrophysical jets. Understa…
