The discovery of pulsars opened a new research field that allows studying a wide range of
physics under extreme conditions. More than 3,000 pulsars are currently known, including …

Radio-loud compact radio sources (CRSs) are characterised by morphological compactness
of the jet structure centred on the active nucleus of the galaxy. Most of the local elliptical …

The origin of high-energy cosmic rays, atomic nuclei that continuously impact Earth's
atmosphere, is unknown. Because of deflection by interstellar magnetic fields, cosmic rays …

We present an incremental version (4FGL-DR3, for Data Release 3) of the fourth Fermi
Large Area Telescope (LAT) catalog of γ-ray sources. Based on the first 12 years of science …

The extension of the cosmic-ray spectrum beyond 1 petaelectronvolt (PeV; 1015
electronvolts) indicates the existence of the so-called PeVatrons—cosmic-ray factories that …

A supermassive black hole, obscured by cosmic dust, powers the nearby active galaxy NGC
1068. Neutrinos, which rarely interact with matter, could provide information on the galaxy's …

This Letter presents the results from pointlike neutrino source searches using ten years of
IceCube data collected between April 6, 2008 and July 10, 2018. We evaluate the …

Fewer than a dozen gamma-ray pulsars were known when the Fermi Gamma-ray Space
Telescope was launched on 2008 June 11, and the extent and diversity of the population …

An energetic γ-ray burst (GRB), GRB 211211A, was observed on 11 December 2021,.
Despite its long duration, typically associated with bursts produced by the collapse of …

Thanks to its broad energy range, excellent sensitivity, and all-sky monitoring capabilities,
the Fermi Gamma-ray Space Telescope Large Area Telescope (LAT) has revolutionized our …
