BL Lacertae Objects and the Extragalactic Gamma-Ray Background
A tight correlation between gamma-ray and radio emission is found for a sample of BL Lacertae (BL Lac) objects detected by Fermi Gamma-ray Space Telescope (Fermi) and the Energetic Gamma-Ray Experiment Telescope (EGRET).

Outliers in Spectral Time Lag-Selected Gamma Ray Bursts
It is possible that astrophysical samples are polluted by some outliers, which might belong to a different sub-class. By removing the outliers, the underlying statistical features may be revealed.

Fermi LAT measurements of diffuse gamma-ray emission: results at the first-year milestone
For more than one year the Fermi Large Area Telescope has been surveying the gamma-ray sky from 20 MeV to more than 300 GeV with unprecedented statistics and angular resolution.

Swift Pointing and Gravitational-Wave Bursts from Gamma-Ray Burst Events
The currently accepted model for gamma-ray burst phenomena involves the violent formation of a rapidly rotating solar-mass black hole. Gravitational waves should be associated with the black-hole formation, and their detection would permit this model to ...

Probing Orbital Parameters of Gamma-Ray Binaries with TeV Light Curves
Gamma-ray binaries are binary systems in which the energy flux peaks in the gamma-ray energy band. They harbor a compact object (a neutron star or a black hole) orbiting around a massive star, which provides a strong radiation field.

A Roadmap to Gamma-Ray Bursts: New Developments and Applications to Cosmology
Gamma-ray bursts are the most powerful explosions in the universe and are mainly placed at very large redshifts, up to z≃9. In this short review, we first discuss gamma-ray burst classification and morphological properties.

The Fermi Gamma-ray Burst Monitor: Results from the first two years [PDF]
In the first two years since the launch of the Fermi Observatory, the Gamma-ray Burst Monitor (GBM) has detected over 500 Gamma-Ray Bursts (GRBs), of which 18 were confidently detected by the Large Area Telescope (LAT) above 100 MeV.

The role of histone modifications in transcription regulation upon DNA damage
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Gamma ray effects on flash memory cell arrays [PDF]
Information stored in flash memories is physically represented by the absence or presence of charge on electrically isolated floating gates. Interaction of gamma rays with the insulators surrounding the floating gate produces effects that degrade the ...

Discovery of gamma-ray emission from a strongly lobe-dominated quasar 3C 275.1
We systematically analyze the 6-year {\it Fermi}/LAT data of the lobe-dominated quasars (LDQs) in the complete LDQ sample from 3CRR survey and report the discovery of high-energy $\gamma$-ray emission from 3C 275.1. The $\gamma$-ray emission of 3C 207 is
