Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies

S. Abe, J. Abhir, A. Abhishek +457

The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…

An Afterglow Study of the "New Year's Burst" GRB 220101A

Agniva Roychowdhury, Tuomas Kangas, Andrew Fruchter +12

We present a detailed broadband afterglow study of GRB 220101A ( s) combining multi-wavelength data from soft X-rays until 6 GHz. The afterglow light c…

X-ray Analysis of Gamma-Ray Burst Flares and Underlying Afterglows: Insights into Origin of Flares

H. Dereli-Bégué, A. Pe'er, D. Bégué +2

Gamma-ray burst (GRB) X-ray light curves exhibit a variety of complex temporal structures, such as flares and plateaus. The origin of flares seen in many GRB early afterglows is st…

Gamma-ray burst pulse structures and emission mechanisms

A Gowri, A. Pe'er, F. Ryde +1

The prompt phase X- and -ray light curves of gamma-ray bursts (GRBs) exhibit erratic and complex behaviour, often with multiple pulses. The temporal shape of individual pulses…

Modeling blazar broadband emission with convolutional neural networks -- III. proton synchrotron and hybrid models

N. Sahakyan, D. Bégué, A. Casotto +5

Modeling the broadband emission of blazars has become increasingly challenging with the advent of multimessenger observations. Building upon previous successes in applying convolut…

Galactic transient sources with the Cherenkov Telescope Array Observatory

Cherenkov Telescope Array Observatory Consortium

A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…
