Very high energy gamma-ray emission beyond 10 TeV from GRB 221009A
Zhen Cao, F. Aharonian, Q. An +276
The highest energy gamma-rays from gamma-ray bursts (GRBs) have important implications for their radiation mechanism. Here we report for the first time the detection of gamma-rays…
Does or did the supernova remnant Cassiopeia A operate as a PeVatron?
Zhen Cao, F. Aharonian, Q. An +276
For decades, supernova remnants (SNRs) have been considered the prime sources of Galactic Cosmic rays (CRs). But whether SNRs can accelerate CR protons to PeV energies and thus dom…
An Ultrahigh-energy -ray Bubble Powered by a Super PeVatron
The LHAASO Collaboration, Z. Cao, F. Aharonian +277
We report the detection of a -ray bubble spanning at least 100 in ultra high energy (UHE) up to a few PeV in the direction of the star-forming region Cygnus X, implyi…
Chasing Gravitational Waves with the Cherenkov Telescope Array
Jarred Gershon Green, Alessandro Carosi, Lara Nava +563
The detection of gravitational waves from a binary neutron star merger by Advanced LIGO and Advanced Virgo (GW170817), along with the discovery of the electromagnetic counterparts…
Interpolation of Instrument Response Functions for the Cherenkov Telescope Array in the Context of pyirf
Rune Michael Dominik, Maximilian Linhoff, Julian Sitarek
The Cherenkov Telescope Array (CTA) will be the next generation ground-based very-high-energy gamma-ray observatory, constituted by tens of Imaging Atmospheric Cherenkov Telescopes…
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…
A tera-electronvolt afterglow from a narrow jet in an extremely bright gamma-ray burst 221009A
LHAASO Collaboration
Some gamma-ray bursts (GRBs) have an afterglow in the tera-electronvolt (TeV) band, but the early onset of this afterglow has not been observed. We report observations with the Lar…
Sensitivity of the Cherenkov Telescope Array to TeV photon emission from the Large Magellanic Cloud
The Cherenkov Telescope Array Consortium
A deep survey of the Large Magellanic Cloud at ~0.1-100TeV photon energies with the Cherenkov Telescope Array is planned. We assess the detection prospects based on a model for the…
The First LHAASO Catalog of Gamma-Ray Sources
Zhen Cao, F. Aharonian, Q. An +276
We present the first catalog of very-high energy and ultra-high energy gamma-ray sources detected by the Large High Altitude Air Shower Observatory (LHAASO). The catalog was compil…
Measurement of ultra-high-energy diffuse gamma-ray emission of the Galactic plane from 10 TeV to 1 PeV with LHAASO-KM2A
Zhen Cao, F. Aharonian, Q. An +276
The diffuse Galactic -ray emission, mainly produced via interactions between cosmic rays and the interstellar medium and/or radiation field, is a very important probe of the dis…
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…
Exploring TeV candidates of Fermi blazars through machine learning
J. T. Zhu, C. Lin, H. B. Xiao +3
In this work, we make use of a supervised machine learning algorithm based on Logistic Regression (LR) to select TeV blazar candidates from the 4FGL-DR2 / 4LAC-DR2, 3FHL, 3HSP, and…
Fermi-GBM Discovery of GRB 221009A: An Extraordinarily Bright GRB from Onset to Afterglow
S. Lesage, P. Veres, M. S. Briggs +136
We report the discovery of GRB 221009A, the highest flux gamma-ray burst ever observed by the Fermi Gamma-ray Burst Monitor (GBM). This GRB has continuous prompt emission lasting m…
The Fermi-LAT Light Curve Repository
S. Abdollahi, M. Ajello, L. Baldini +110
The Fermi Large Area Telescope (LAT) light curve repository (LCR) is a publicly available, continually updated library of gamma-ray light curves of variable Fermi-LAT sources gener…
