A post-hypercritical accretion small-scale dynamo in newborn neutron stars

David F. Bambague, Cristian G. Bernal, J. A. Rueda

Hypercritical fallback accretion can advect the surface magnetic field of a newborn neutron star into the newly accreted outer layers. Before this material joins the solid crust an…

Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes

K. Abe, S. Abe, J. Abhir +439

We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…

Sub-stellar Strange Quark Matter Objects: Predicting a New Class of Highly-Compact Candidates

Jonathan Joás Zapata Campos, Rodrigo Negreiros

We investigate the existence and stability of highly-compact sub-stellar objects composed of strange quark matter (SQM), focusing on finite-size strangelets with baryon number $A \…

Search for long-term variability of HESS J1745-290

H. E. S. S. Collaboration, :, A. Acharyya +116

At the center of our Galaxy lies the bright γ-ray point-like source HESS J1745-290, which is compatible in position with Sgr A star, although an association between the two remain…

Long-term study of the gamma-ray emission of Cygnus X-3 with MAGIC and Fermi-LAT

K. Abe, S. Abe, J. Abhir +185

Cygnus X-3 is a microquasar composed of a compact object of unknown nature closely orbiting around a Wolf-Rayet star. The particularities of this source make it a unique case among…

Optical transients from non-explosive double white-dwarf mergers: the case of a central neutron star remnant

M. M. Ridha Fathima, Alexandre M. R. Almeida, Mattia Bulla +3

Discoveries of ultra-massive magnetic white dwarfs (WDs) and peculiar pulsars have been proposed to originate in double white dwarf (DWD) mergers. There are three possible post-mer…
