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…
Continuation of an Optical Spectroscopic Campaign of Fermi Blazar Candidates with TNG: Discovery of a New Changing-Look Blazar
N. Álvarez Crespo, A. Domínguez, V. S. Paliya +3
Context. Blazars are a distinct subclass of active galactic nuclei (AGN), known for their fast variability, high polarization, and intense emission across the electromagnetic spect…
A new method of reconstructing images of gamma-ray telescopes applied to the LST-1 of CTAO
CTA-LST Project, :, K. Abe +305
Imaging atmospheric Cherenkov telescopes (IACTs) are used to observe very high-energy photons from the ground. Gamma rays are indirectly detected through the Cherenkov light emitte…
A detailed study of the very-high-energy Crab pulsar emission with the LST-1
CTA-LST Project, :, K. Abe +294
Context: There are currently three pulsars firmly detected by imaging atmospheric Cherenkov telescopes (IACTs), two of them reaching TeV energies, challenging models of very-high-e…
Performance of the joint LST-1 and MAGIC observations evaluated with Crab Nebula data
H. Abe, K. Abe, S. Abe +365
Aims. LST-1, the prototype of the Large-Sized Telescope for the upcoming Cherenkov Telescope Array Observatory, is concluding its commissioning in Observatorio del Roque de los Muc…
Observations of the Crab Nebula and Pulsar with the Large-Sized Telescope Prototype of the Cherenkov Telescope Array
CTA-LST Project, :, H. Abe +289
CTA (Cherenkov Telescope Array) is the next generation ground-based observatory for gamma-ray astronomy at very-high energies. The Large-Sized Telescope prototype (LST-1) is locate…
Sensitivity of the Cherenkov Telescope Array to spectral signatures of hadronic PeVatrons with application to Galactic Supernova Remnants
The Cherenkov Telescope Array Consortium, F. Acero, A. Acharyya +356
The local Cosmic Ray (CR) energy spectrum exhibits a spectral softening at energies around 3~PeV. Sources which are capable of accelerating hadrons to such energies are called hadr…
Multi-wavelength study of the galactic PeVatron candidate LHAASO J2108+5157
S. Abe, A. Aguasca-Cabot, I. Agudo +267
LHAASO J2108+5157 is one of the few known unidentified Ultra-High-Energy (UHE) gamma-ray sources with no Very-High-Energy (VHE) counterpart, recently discovered by the LHAASO colla…
Optical spectroscopic characterization of Fermi blazar candidates of uncertain type with TNG and DOT: First Results
Amanda Olmo-GarcÍa, Vaidehi S. Paliya, Nuria Álvarez Crespo +4
The classification of gamma-ray-detected blazar candidates of uncertain type (BCU) is a relevant problem in extragalactic gamma-ray astronomy. Here we report the optical spectrosco…
An XMM-Newton catalogue of BL Lacs
I. de la Calle Pérez, N. Álvarez Crespo, E. Racero +1
We present an XMM-Newton catalogue of BL Lac X-ray, optical, and UV properties based on cross-correlation with the 1151 BL Lacs listed in the fifth edition of the Roma-BZCAT. We se…
ESASky SSOSS: Solar System Object Search Service and the case of Psyche
E. Racero, F. Giordano, B. Carry +18
We introduce in this work the Solar System Object Search Service (SSOSS), a service aimed at providing the scientific community with a search service for all potential detections o…
Hunting misaligned radio-loud AGN (MAGN) candidates among the uncertain -ray sources of the third Fermi-LAT Catalogue
G. Chiaro, M. Meyer, N. Alvarez Crespo +6
BL Lac Objects (BL Lacs) and Flat Spectrum Radio Quasars (FSRQs) are radio-loud active galaxies (AGNs) whose jets are seen at a small viewing angle (blazars), while Misaligned Acti…
The Gamma-ray Blazar Quest: new optical spectra, state of art and future perspectives
F. Massaro, N. Álvarez Crespo, R. D'Abrusco +13
We recently developed a procedure to recognize gamma-ray blazar candidates within the positional uncertainty regions of the unidentified/unassociated gamma-ray sources (UGSs). Such…
