Status of the GAMMA-400 project [PDF]

open access: yesAdvances in Space Research, 2013
The preliminary design of the new space gamma-ray telescope GAMMA-400 for the energy range 100 MeV - 3 TeV is presented. The angular resolution of the instrument, 1-2 at E ~100 MeV and ~0.01^{\circ} at E > 100 GeV, its energy resolution ~1% at E > 100 GeV, and the proton rejection factor ~10E6 are optimized to address a broad range of ...

An estimated 400–800 million tons of prey are annually killed by the global spider community

open access: yesSCIENCE NATURE, 2017
Spiders have been suspected to be one of the most important groups of natural enemies of insects worldwide. To document the impact of the global spider community as insect predators, we present estimates of the biomass of annually killed insect prey. Our
