The First LHAASO Catalog of Gamma-Ray Sources [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2023
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. The catalog was compiled using 508 days of data collected by the Water Cherenkov Detector Array from 2021

Very high-energy gamma-ray emission beyond 10 TeV from GRB 221009A. [PDF]

open access: yesSci Adv, 2023
The highest-energy gamma-rays from gamma-ray bursts (GRBs) have important implications for their radiation mechanism. Here we report the detection of gamma-rays up to 13 teraelectronvolts from the brightest GRB 221009A by the Large High Altitude Air ...

A kilonova following a long-duration gamma-ray burst at 350 Mpc [PDF]

open access: yesNature, 2022
Gamma-ray bursts (GRBs) are divided into two populations1,2; long GRBs that derive from the core collapse of massive stars (for example, ref. 3) and short GRBs that form in the merger of two compact objects4,5.

A long-duration gamma-ray burst with a peculiar origin [PDF]

open access: yesNature, 2022
It is generally believed that long-duration gamma-ray bursts (GRBs) are associated with massive star core collapse1, whereas short-duration GRBs are associated with mergers of compact star binaries2.

Peta–electron volt gamma-ray emission from the Crab Nebula [PDF]

open access: yesScience, 2021
High-energy photons from the Crab Nebula The Crab Nebula contains a pulsar that excites the surrounding gas to emit high-energy radiation. The combination of the pulsar's youth and nearby location makes the nebula the brightest gamma-ray source in the ...

Revealing x-ray and gamma ray temporal and spectral similarities in the GRB 190829A afterglow. [PDF]

open access: yesScience, 2021
Gamma-ray bursts (GRBs), which are bright flashes of gamma rays from extragalactic sources followed by fading afterglow emission, are associated with stellar core collapse events.

The Gamma-ray Window to Intergalactic Magnetism [PDF]

open access: yesUniverse, 2021
One of the most promising ways to probe intergalactic magnetic fields (IGMFs) is through gamma rays produced in electromagnetic cascades initiated by high-energy gamma rays or cosmic rays in the intergalactic space.

Research Progress on the Application of Irradiation Technology in Meat and Meat Products

open access: yesShipin gongye ke-ji, 2023
Meat and meat product irradiation is a non-thermal sterilization technology that uses high-energy ionizing rays to improve safety and extend storage period, effectively killing spoilage microorganisms and extending the storage period of meat and meat ...

The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars

open access: yesAstrophysical Journal, 2023
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected

The Fourth Fermi-GBM Gamma-Ray Burst Catalog: A Decade of Data [PDF]

open access: yesAstrophysical Journal, 2020
We present the fourth in a series of catalogs of gamma-ray bursts (GRBs) observed with Fermi’s Gamma-ray Burst Monitor (Fermi-GBM). It extends the six year catalog by four more years, now covering the 10 year time period from trigger enabling on 2008 ...
