The Milagro Gamma-Ray Observatory
Milagro is a unique water Cherenkov detector designed for very high energy (VHE) gamma-ray astronomy. The water Cherenkov technique gives Milagro an unprecedented sensitivity and energy threshold. A deep detector layer is used to identify penetrating particles (muons and hadrons) present in hadron induced showers allowing for the rejection of backgrounds which substantially increases sensitivit...
متن کاملStatus of the Milagro Gamma Ray Observatory
The Milagro Gamma Ray Observatory, located at an altitude of 8,600 feet in the Jemez Mountains of New Mexico, is the world’s first large-area water Cherenkov detector capable of continuously monitoring the entire sky for sources of TeV gamma rays. It is uniquely capable of searching for transient sources of VHE gamma rays. The core of the detector is a 60m x 80m x 8m pond instrumented with 723 ...
متن کاملResults from the Milagro Gamma-Ray Observatory
The Milagro Gamma-Ray Observatory, located at an altitude of 2630m in the mountains of northern New Mexico, is a water-Cherenkov extensive air shower detector consisting of a 4800m covered pond instrumented with 723 PMTs. For improved sensitivity, 175 instrumented water tanks have recently been added surrounding the pond, covering an area of 40, 000m. Milagro continuously observes the entire ov...
متن کاملMilagro–A TeV Observatory for Gamma Ray Bursts
Milagro is a large field of view (∼ 2 sr), high duty cycle (∼90%), ground-based observatory sensitive to gamma-rays above ∼100 GeV. This unique detector is ideal for observing the highest energy gamma-rays from gamma-ray bursts. The highest energy gamma rays supply very strong constraints on the nature of gamma-ray burst sources as well as fundamental physics. Because the highest energy gamma-r...
متن کاملThe Highest - Energy Photons Seen by the Energetic Gamma Ray Experiment Telescope ( EGRET ) on the Compton Gamma Ray Observatory
During its nine-year lifetime, the Energetic Gamma Ray Experiment Telescope (EGRET) on the Compton Gamma Ray Observatory (CGRO) detected 1506 cosmic photons with measured energy E>10 GeV. Of this number, 187 are found within a 1 • of sources that are listed in the Third EGRET Catalog (Hart-man et al. 1999) and were included in determining the detection likelihood, flux, and spectra of those sou...
