The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision
G. E. Anderson, G. P. Lamb, B. P. Gompertz +64
We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift . The Australia Telescope Compact Array automatic…
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…
Diffusion of muonic hydrogen in hydrogen gas and the measurement of the 1 hyperfine splitting of muonic hydrogen
J. Nuber, A. Adamczak, M. Abdou Ahmed +46
The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (p) with 1 ppm accuracy by means of pulsed laser spectroscopy…
Intercomparison of a High-Resolution Regional Climate Model Ensemble for Catchment-Scale Water Cycle Processes under Human Influence
J. L. Roque, F. Da Silva Lopes, J. A. Giles +8
Understanding regional hydroclimatic variability and its drivers is essential for anticipating the impacts of climate change on water resources and sustainability. Yet, considerabl…
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…
A search for the afterglows, kilonovae, and host galaxies of two short GRBs: GRB 211106A and GRB 211227A
M. Ferro, R. Brivio, P. D'Avanzo +30
Context: GRB 211106A and GRB 211227A are recent gamma-ray bursts (GRBs) with initial X-ray positions suggesting associations with nearby galaxies (z < 0.7). Their prompt emission c…
Laser excitation of the 1s-hyperfine transition in muonic hydrogen
P. Amaro, A. Adamczak, M. Abdou Ahmed +43
The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (p) with 1 ppm accuracy by means of pulsed laser spectroscopy…
GRB 241030A: a bright afterglow challenging forward shock emission
J. -G. Ducoin, C. Pellouin, V. Aivazyan +97
Gamma-Ray Burst GRB 241030A (z = 1.411) exhibited a bright afterglow (similar to GRB 221009A), detected across gamma-ray, X-ray, UV, and optical bands, providing a probe of GRB aft…
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…
Laser Excitation of Muonic 1S Hydrogen Hyperfine Transition: Effects of Multi-pass Cell Interference
M. Ferro, P. Amaro, L. Sustelo +10
Calculating the laser-induced transition probability by using the fluence distribution that neglects interference effects (e.g., by employing ray-tracing methods) can lead to an ov…
The Stern-Gerlach interaction between a traveling particle and a time varying magnetic field
M. Conte, M. Ferro, G. Gemme +3
The general expression of the Stern-Gerlach force is deduced for a charged particle, endowed with a magnetic moment, which travels inside a time varying magnetic field. Then, the e…
Multiwavelength properties of short gamma ray bursts with extended emission observed by Swift
