Investigating Active Galactic Nuclei variability with the Cherenkov Telescope Array Observatory
G. Grolleron, J. Biteau, M. Cerruti +21
Blazars, a type of active galactic nuclei (AGN) with relativistic jets pointed at the observer, exhibit flux variability across the electromagnetic spectrum due to particle acceler…
CTAO LST-1 observations of magnetar SGR 1935+2154: Deep limits on sub-second bursts and persistent tera-electronvolt emission
K. Abe, S. Abe, A. Abhishek +333
The Galactic magnetar SGR 1935+2154 has exhibited prolific high-energy (HE) bursting activity in recent years. Investigating its potential tera-electronvolt counterpart could provi…
VHE -ray observations of bright BL Lacs with the Large-Sized Telescope prototype (LST-1) of the CTAO
The CTAO-LST Project, :, K. Abe +331
Cherenkov Telescope Array Observatory (CTAO) is the next-generation ground-based gamma-ray observatory operating in the energy range from 20 GeV up to 300 TeV, with two sites in La…
Ultra-luminous X-ray pulsars as sources of TeV neutrinos
L. Ducci, E. Perinati, P. Romano +4
We explored the expected properties of the neutrino emission from accreting neutron stars in X-ray binaries using numerical simulations. The simulations are based on a model in whi…
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…
GRB 221009A: Observations with LST-1 of CTAO and Implications for Structured Jets in Long Gamma-Ray Bursts
LST Collaboration, K. Abe, S. Abe +328
GRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing…
Detection of the Geminga pulsar at energies down to 20 GeV with the LST-1 of CTAO
The CTAO-LST Project, :, K. Abe +331
Geminga is the third gamma-ray pulsar firmly detected by imaging atmospheric Cherenkov telescopes (IACTs) after the Crab and the Vela pulsars. Most of its emission is expected at t…
Swift/XRT monitoring of the orbital and superorbital modulations in 4U 1909+07
P. Romano, H. I. Cohen, E. Bozzo +5
We report on an observational campaign performed with Swift/XRT on the wind-fed supergiant X-ray binary 4U 1909+07 to investigate the nature of the orbital and superorbital modulat…
Detection of RS Oph with LST-1 and modelling of its HE/VHE gamma-ray emission
CTA-LST Project, :, K. Abe +316
The recurrent nova RS Ophiuchi (RS Oph) underwent a thermonuclear eruption in August 2021. In this event, RS Oph was detected by the High Energy Stereoscopic System (H.E.S.S.), the…
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…
Probing the emission mechanism and nature of the pulsating compact object in the X-ray binary SAX J1324.4-6200
L. Ducci, E. Bozzo, M. Burgay +6
Recently, there has been renewed interest in the Be X-ray binary (Be/XRB) SAX J1324.4-6200 because of its spatial coincidence with a gamma-ray source detected by Fermi/LAT. To expl…
Dark Matter Line Searches with the Cherenkov Telescope Array
S. Abe, J. Abhir, A. Abhishek +562
Monochromatic gamma-ray signals constitute a potential smoking gun signature for annihilating or decaying dark matter particles that could relatively easily be distinguished from a…
NuSTAR and Swift observations of two supergiant fast X-ray transients: AX J1841.0-0536 and SAX J1818.6-1703
E. Bozzo, C. Ferrigno, P. Romano
Supergiant fast X-ray transients are wind-fed binaries hosting neutron star accretors, which display a peculiar variability in the X-ray domain. Different models have been proposed…
