Detection of the distant quasar OP 313 with the first Large-Sized Telescope of CTAO
K. Abe, S. Abe, J. Abhir +412
In December 2023, the Large-Sized Telescope prototype (LST-1) detected for the first time VHE -ray emission from the FSRQ OP~313 becoming the furthest blazar ever observed at VH…
AGILE detection of transient γ-ray emission from the region of the supergiant fast X-ray transient source IGR J17354-3255
Andrea Bulgarelli, Gabriele Panebianco, Vito Sguera +16
Context. On April 14, 2009, the AGILE satellite detected a γ-ray flare from an unknown transient source. Subsequent X-ray follow-up observations with Swift and INTEGRAL identified…
Multi-mission Investigation of X-ray Superorbital Modulation in the Supergiant High Mass X-ray Binary 4U 1538-52
H. I. Cohen, N. Islam, R. H. D. Corbet +7
Superorbital modulations has been detected in the supergiant High-Mass X-ray binary 4U 1538-52 using long-term monitoring with the Neil Gehrels Swift Observatory Burst Alert Telesc…
Accretion disc by Roche lobe overflow in the supergiant fast X-ray transient IGR J08408-4503
L. Ducci, P. Romano, L. Ji +1
Supergiant fast X-ray transients (SFXTs) are X-ray binary systems with a supergiant companion and likely a neutron star, which show a fast ( s) and high variability with…
Exploring the role of X-ray reprocessing and irradiation in the anomalous bright optical outbursts of A0538-66
L. Ducci, S. Mereghetti, K. Hryniewicz +2
In 1981, the Be/X-ray binary (Be/XRB) A0538-66 showed outbursts characterized by high peak luminosities in the X-ray and optical bands. The optical outbursts were qualitatively exp…
Putting the hadron beam scenario for extreme blazars to the test with the Cherenkov Telescope Array
F. Tavecchio, P. Romano, M. Landoni +1
Hadron beams are invoked to explain the peculiar properties of a subclass of BL Lac objects, the so-called extreme BL Lacs (EHBLs). This scenario predicts a quite distinctive featu…
