Observation of thundercloud-related gamma rays and neutrons in Tibet [PDF]
, 2012 During the 2010 rainy season in Yangbajing (4300 m above sea level) in Tibet, China, a long-duration count enhancement associated with thunderclouds was detected by a solar-neutron telescope and neutron monitors installed at the Yangbajing Comic Ray ...

Detection of Pulsed Gamma Rays Above 100 GeV from the Crab Pulsar [PDF]
Science, 2011 This detection constrains the mechanism and emission region of gamma-ray radiation in the pulsar’s magnetosphere. We report the detection of pulsed gamma rays from the Crab pulsar at energies above 100 giga–electron volts (GeV) with the Very Energetic ...

Gamma-ray luminosity function of gamma-ray bright AGNs [PDF]
Research in Astronomy and Astrophysics, 2009 Detection of Gamma-ray emission from a class of active galactic nuclei (viz blazars), has been one of the important findings from the Compton Gamma Ray Observatory (CGRO). However, their Gamma-ray luminosity function has not been well determined. Few attempts have been made in earlier works, where BL Lacs and Flat Spectrum Radio Quasars (FSRQs) have ...

Multiwavelength Variability Analysis of 3C 279
Frontiers in Astronomy and Space Sciences, 2017 We present a multifrequency analysis of the variability in the flat-spectrum radio quasar 3C 279 from 2008 to 2014. Our multiwavelength datasets range from 1 mm to gamma-rays, with additional optical polarimetry.

CONSTRAINTS ON COSMIC RAYS, MAGNETIC FIELDS, AND DARK MATTER FROM GAMMA-RAY OBSERVATIONS OF THE COMA CLUSTER OF GALAXIES WITH VERITAS AND FERMI [PDF]
, 2012 Observations of radio halos and relics in galaxy clusters indicate efficient electron acceleration. Protons should likewise be accelerated and, on account of weak energy losses, can accumulate, suggesting that clusters may also be sources of very high ...

, 2022 While the scientific potential of high-energy X-ray and gamma-ray polarimetry has long been recognized, measuring the polarization of high-energy photons is challenging. To date, there has been very few significant detections from an astrophysical source.

Induced variability in quantitative characters of groundnut (Arachis hypogaea L.) [PDF]
Electronic Journal of Plant Breeding, 2010 Groundnut genotype AK-280 was treated with EMS 40 mM, 60 mM, gamma rays 30 kR, 40 kR, 50 kR and combination treatment of EMS 20mM + gamma rays 20 kR. The observations on various quantitative characters were recorded in M2 generation.
