The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 3
LAT collaboration, Marco Ajello, Luca Baldini +100
An incremental version of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-Large Area Telescope is presented. This version (4LAC-DR3) derives from the thir…
Constraining the -ray Emission Region for Fermi-Detected FSRQs by the Seed Photon Approach
Danyi Huang, Ziyan Li, Jiru Liao +5
The location of -ray emitting region in blazars has been an open issue for several decades and is still being debated. We use the Paliya et al. sample of 619 -ray-loud flat-s…
Search for new cosmic-ray acceleration sites within the 4FGL catalog Galactic plane sources
LAT Collaboration, S. Abdollahi, F. Acero +117
Cosmic rays are mostly composed of protons accelerated to relativistic speeds. When those protons encounter interstellar material, they produce neutral pions which in turn decay in…
A Gamma-ray Pulsar Timing Array Constrains the Nanohertz Gravitational Wave Background
M. Ajello, W. B. Atwood, L. Baldini +129
After large galaxies merge, their central supermassive black holes are expected to form binary systems whose orbital motion generates a gravitational wave background (GWB) at nanoh…
Incremental Fermi Large Area Telescope Fourth Source Catalog
LAT collaboration, Soheila Abdollahi, Fabio Acero +137
We present an incremental version (4FGL-DR3, for Data Release 3) of the fourth Fermi-LAT catalog of gamma-ray sources. Based on the first twelve years of science data in the energy…
