Recent Highlights from the VERITAS AGN Program VERITAS is one of the world’s most sensitive detectors of astrophysical very high energy (VHE; E > 100 GeV) gamma rays. This observatory began full-scale operations in 2007, and more than 8,000 hours of its good-weather observations have been targeted on active galactic...

Exploring the signatures of cosmic ray feedback effects in galaxy ecosystems Cosmic rays go hand-in-hand with violent and energetic astrophysical conditions. They are an active agent within galactic and circumgalactic ecosystems, where they can deposit energy and momentum, modify the circulation of baryons, and even have the potential to regulate...

Civilian and military use of nuclear technology To exploit nuclear technology for civilian purposes, in particular energy production, a variety of facilities - a nuclear fuel cycle - is necessary, comprising reactors and uranium enrichment plants among others. These same facilities, however, produce the fissile materials that are required to...
