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…
XMM-Newton multi-year campaign on NGC 55 ULX-1: Resolving the wind and its variability with RGS
C. Pinto, S. Caserta, F. Barra +12
Winds are an important ingredient in the evolution of X-ray binary (XRB) systems, particularly those at high accretion rates such as ultra-luminous X-ray sources (ULXs), because th…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
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…
The persistent nature of the Be X-ray binary pulsar 4U 0728-25
N. La Palombara, L. Sidoli, S. Mereghetti +2
We report the results obtained with a XMM-Newton observation, performed in April 2023, of the poorly known Galactic Be X-ray binary pulsar 4U 0728-25. It was revealed at a flux lev…
