Observations of AGN with the First VERITAS Telescope
نویسنده
چکیده
The first VERITAS (Very Energetic Radiation Imaging Telescope Array System) telescope has been in operation at the basecamp of the Whipple Observatory since January 2005. Here we present initial observations of AGN made using this telescope. Although this is engineering data, significant detections of Markarian 421 and Markarian 501 have been achieved.

Veritas: Status and Performance
VERITAS is an atmospheric Cherenkov telescope array sited in Tucson, Ari-zona. The array is nearing completion and consists of four, 12 m diameter telescopes. The first telescope in the array has been operating since February 2005, while observations with the full array are expected to begin in January, 2007. We report here in some detail on the performance of the first VERITAS telescope, and b...
متن کاملBlazar Observations with VERITAS
The Very Energetic Radiation Imaging Telescope Array System (VERITAS) is an array of four 12m diameter Imaging Atmospheric Cherenkov Technique (IACT) telescopes operated at the base of Mt. Hopkins in southern Arizona. The four-telescope experiment started operation in April, 2007. GeV and TeV gamma-ray observations of blazars can be used to probe the structure and composition of their jets, and...
متن کاملVERITAS Observations of the Arrival Directions of the Highest Energy Cosmic Rays
The recent discovery by the Pierre Auger collaboration of anisotropy in the arrival directions of the highest energy cosmic rays, correlated with the positions of nearby active galactic nuclei [1, 2], encourages the search for counterpart TeV gammaray emission. Approximately half of the sky viewed by the southern hemisphere Pierre Auger experiment is also visible at reasonable elevations for th...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE Observations of Mrk 421 and Mrk 501 in Spring 2006 with VERITAS
VERITAS, the Very Energetic Radiation Telescope Imaging Array System, is an array of four imaging Atmospheric Cherenkov telescopes in southern Arizona. It is sensitive to gamma rays at energies above 100GeV. Here, we discuss the results of observations of two well known VHE blazars, Markarian 421 and Markarian 501, during Spring 2006 which were made with the first two telescopes during the comi...
متن کاملA first joint M87 campaign in 2008 from radio to TeV gamma-rays
M87, the central galaxy of the Virgo Cluster, is the first radio galaxy detected in the TeV regime. The structure of its jet, which is not pointing toward the line of sight, is spatially resolved in X-ray (by Chandra), in optical and in radio observations. Time correlation between the TeV flux and emission at other wavelengths provides a unique opportunity to localize the very high energy gamma...
