As a smaller city, Flagstaff maintains a "central business district that exists at a more human scale and [relies] more on independent local and regional business entrepreneurs" in its downtown area. [8] DK writes that "it is a lively, easy-going place with a good selection of bars and restaurants among the maze of old red-brick buildings". [1]
Cosmic ray astronomy is a branch of observational astronomy where scientists attempt to identify and study the potential sources of extremely high-energy (ranging from 1 MeV to more than 1 EeV) charged particles called cosmic rays coming from outer space.
Flagstaff (/ ˈ f l æ ɡ. s t æ f / FLAG-staf) is the county seat of Coconino County, Arizona, in the southwestern United States. As of the 2020 United States census, the city's population was 76,831. Flagstaff is the principal city of the Flagstaff metropolitan area, which includes all of Coconino County, and has a population of
Right image: cosmic ray muon losing considerable energy after passing through the plate as indicated by the increased curvature of the track in a magnetic field. Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light.
About 90% of cosmic rays are protons, 9% are alpha particles, and the remaining ~1% are other particles. It is not yet possible to build image forming optics for cosmic rays, like a Wolter telescope for lower energy X-rays, [1] [2] although some cosmic-ray observatories also look for high energy gamma rays and x-rays.
The GZK limit only applies if ultra-high-energy cosmic rays are mostly protons. In July 2007, during the 30th International Cosmic Ray Conference in Mérida, Yucatán, México, the High Resolution Fly's Eye Experiment (HiRes) and the Pierre Auger Observatory (Auger) presented their results on ultra-high-energy cosmic rays (UHECR). HiRes ...
For years, the Weatherford Hotel was the most prominent hotel in Flagstaff, entertaining guests such as artist Thomas Moran, publisher William Randolf Hearst, and writer Zane Grey. Grey's famous novel " The Call of the Canyon " was written in the recently renovated Zane Grey Ballroom on the third floor of the hotel.
