Construction and On-site Performance of the LHAASO WFCTA Camera
F. Aharonian, Q. An, Axikegu +246
The focal plane camera is the core component of the Wide Field-of-view Cherenkov/fluorescence Telescope Array (WFCTA) of the Large High-Altitude Air Shower Observatory (LHAASO). Be…
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 2
B. Lott, D. Gasparrini, S. Ciprini
An incremental version (4LAC-DR2) of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT is presented. This version is associated with the second release…
The observation of the Crab Nebula with LHAASO-KM2A for the performance study
F. Aharonian, Q. An, Axikegu +246
As a sub-array of the Large High Altitude Air Shower Observatory (LHAASO), KM2A is mainly designed to cover a large fraction of the northern sky to hunt for gamma-ray sources at en…
Beamed and unbeamed emission of -ray blazars
Zhiyuan Pei, Junhui Fan, Jianghe Yang +1
A two-component model of radio emission has been used to explain some radio observational properties of Active Galactic Nuclei (AGNs) and, in particular, of blazars. In this work,…
The estimation of -ray Doppler factor for Fermi/LAT-detected blazars
Zhiyuan Pei, Junhui Fan, Jianghe Yang +1
Blazars are a subclass of active galactic nuclei (AGNs) with extreme observation properties, which is caused by the beaming effect, expressed by a Doppler factor, in a relativistic…
Sensitivity of the Cherenkov Telescope Array to a dark matter signal from the Galactic centre
The Cherenkov Telescope Array Consortium, :, A. Acharyya +449
We provide an updated assessment of the power of the Cherenkov Telescope Array (CTA) to search for thermally produced dark matter at the TeV scale, via the associated gamma-ray sig…
Fermi Large Area Telescope Fourth Source Catalog Data Release 2
J. Ballet, T. H. Burnett, S. W. Digel +1
We present an incremental version (4FGL-DR2, for Data Release 2) of the fourth Fermi-LAT catalog of gamma-ray sources. Based on the first ten years of science data in the energy ra…
Prospects for a Multi-TeV Gamma-ray Sky Survey with the LHAASO Water Cherenkov Detector Array
Yingying Guo, Xiaochuan Chang, Hongbo Hu +1
The Water Cherenkov Detector Array (WCDA) is a major component of the Large High Altitude Air Shower Array Observatory (LHAASO), a new generation cosmic-ray experiment with unprece…
