Fast optical spectroscopic observations of PSR J1023+0038 over one orbital period
M. M. Messa, M. C. Baglio, P. D'Avanzo +8
The paper presents minute‑resolution optical spectroscopy of the transitional millisecond pulsar PSR J1023+0038 over a full orbit, revealing rapid changes in emission‑line properti…
Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf
Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung +103
A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad…
Probing a new subclass of llGRB-SN transients: Insights from EP250304a and its associated supernova
L. Cotter, A. Martin-Carrillo, R. A. J. Eyles-Ferris +60
With the advent of the Einstein Probe (EP) mission, we are entering a new era in the study of gamma-ray bursts (GRBs), enabling the detection of faint, low-luminosity transients th…
The most distant optically polarised GRB afterglow: GRB 240419A at z = 5.178
R. Brivio, S. Covino, M. Ferro +31
Gamma-ray bursts (GRBs) are extremely bright phenomena powered by relativistic jets arising from explosive events at cosmological distances. The nature of the jet and the configura…
An ultraviolet burst oscillation candidate from the low-mass X-ray binary EXO 0748-676
A. Miraval Zanon, F. Ambrosino, G. Illiano +15
X-ray burst oscillations are quasi-coherent periodic signals at frequencies close to the neutron star spin frequency. They are observed during thermonuclear Type I X-ray bursts fro…
Polarized multiwavelength emission from pulsar wind - accretion disk interaction in a transitional millisecond pulsar
M. C. Baglio, F. Coti Zelati, A. Di Marco +17
Transitional millisecond pulsars (tMSPs) bridge the evolutionary gap between accreting neutron stars in low-mass X-ray binaries and millisecond radio pulsars. These systems exhibit…
