Ultra-high-energy (UHE,> 0.1 PeV) γ-ray astronomy is rapidly evolving into an expanding
branch of γ-ray astronomy with the surprising discovery of 12 PeVatrons and the detection of …

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 …

While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

Gamma-ray bursts (GRBs) are short and intense flashes of γ-rays coming from deep space.
GRBs were discovered more than a half century ago and now are observed across the …

Gamma-ray observations of Milky Way dwarf galaxies have been used to place stringent
constraints on the dark matter's annihilation cross section. In this paper, we evaluate the …

New long-lived particles produced at the colliders may escape from conventional particle
detectors. Using satellites or ground telescopes, we can detect the photons generated from …

Context. We have investigated the multiwavelength emission of PSR J2021+ 4026, the only
isolated γ-ray pulsar known to be variable, which in October 2011 underwent a …

Machine learning based approaches are emerging as very powerful tools for many
applications including source classification in astrophysics research due to the availability of …

We present highly sensitive measurements taken with MeerKAT at 1280 MHz as well as
archival Green Bank Telescope (GBT), Murchison Widefield Array, and Very Large Array …
