Follow-up of gravitational waves alerts with IACTs using Astro-COLIBRI
Mathieu de Bony de Lavergne, Halim Ashkar, Atilla Kaan Alkan +4
Follow-up of gravitational wave alerts has proven to be challenging in the past due to the large uncertainty on the localisation, much larger than the field of view of most instrum…
Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts

Fabian Schüssler, Halim Ashkar, Elisa Bernardini +11
The sources of the astrophysical flux of high-energy neutrinos detected by IceCube are still largely unknown, but searches for temporal and spatial correlation between neutrinos an…
, the scientific software for the Cherenkov Telescope Array -- NectarCAM
Guillaume Grolleron, Halim Ashkar, François Brun +8
The NectarCAM is a camera that will be mounted on the Medium-Sized Telescopes of the Cherenkov Telescope Array (CTA) observatory. Along with the hardware integration of the camera,…
Variability studies of active galactic nuclei from the long-term monitoring program with the Cherenkov Telescope Array
Guillaume Grolleron, Josefa Becerra González, Jonathan Biteau +13
Blazars are active galactic nuclei (AGN) with a relativistic jet oriented toward the observer. This jet is composed of accelerated particles which can display emission over the ent…
Performance update of an event-type based analysis for the Cherenkov Telescope Array
Juan Bernete, Orel Gueta, Tarek Hassan +3
The Cherenkov Telescope Array (CTA) will be the next-generation observatory in the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticle physics. The traditional ap…
Dark matter searches in dwarf spheroidal galaxies with the Cherenkov Telescope Array
Francesco Gabriele Saturni, Michele Doro, Aldo Morselli +1
Dark matter (DM) is one of the major components in the Universe. However, at present its existence is still only inferred through indirect astronomical observations. DM particles c…
The peculiar new state of the blazar PKS 1510-089
H. M. Schutte, M. Zacharias, M. Böttcher +4
Contemporaneous multiwavelength observations with H.E.S.S., SALT, Fermi-LAT, Swift, and ATOM show that the blazar PKS 1510-089 suffered a significant decrease in its optical flux,…
Probing VHE gamma-ray emission from GW events with H.E.S.S
Halim Ashkar, Mathieu de Bony de Lavergne, Francois Brun +6
Gravitational wave (GW) events, particularly those connected to the merger of compact objects such as neutron stars, are believed to be the primary source of short gamma-ray bursts…
Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array
The Cherenkov Telescope Array Consortium, :, K. Abe +564
Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…
All sky archival search for FRB high energy counterparts with Swift and Fermi
Halim Ashkar, Mehdi El Bouhaddouti, Stephen Fegan +1
Fast radio bursts (FRBs) are millisecond-duration radio signals from unknown cosmic origin. Many models associate FRBs with high-energy astrophysical objects such as magnetars. In…
