VERITAS, an Imaging Atmospheric Cherenkov Telescope (IACT) system for gammma-ray astronomy in the GeV-TeV range, has recently completed its first season of observations with a full array of four telescopes. A number of astrophysical gamma-ray sources have been detected, both galactic and extragalactic, including sources previously unknown at TeV energies. We describe the status of the array and some highlight results, and assess the technical performance, sensitivity and shower reconstruction capabilities.


Project Management of DAG: Eastern Anatolia Observatory
KESKİN, ONUR; YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; Zago, Lorenzo; Guver, Tolga; Alis, Sinan (2016-06-28)
The four meter DAG (Eastern Anatolia Observatory in Turkish) telescope is not only the largest telescope in Turkey but also the most promising telescope in the northern hemisphere with a large potential to offer scientific observations with its cutting edge technology. DAG is designed to be an AO telescope which will allow both infrared and visible observations with its two Nasmyth platforms dedicated to next generation focal plane instruments. In this paper, status updates from DAG telescope will be presen...
First results from VERITAS
Hanna, D.; et. al. (Elsevier BV, 2008-04-01)
VERITAS is an array of four, 12-m-diameter, Cherenkov telescopes, designed to explore the very-high-energy gamma-ray sky in the energy band between 100 GeV and 50 TeV. Its construction and commissioning have occurred over the past two years and the array has been taking scientific data with three or more telescopes since November 2006. We present results from observations made with VERITAS during the 1 past observing season, including new results on the distant blazar 1ES1218 + 304, the active galaxy M87 an...

This document (Eastern Anatolia Observatory (DAG) is the new observatory of Turkey with the optical and near-infrared largest telescope (4 m class) and its robust observing site infrastructure. This national project consists of three phases with DAG (Telescope, Enclosure, Buildings and Infrastructures), FPI (Focal Plane Instruments and Adaptive Optics) and MCP (Mirror Coating Plant) and is supported by the Ministry of Development of Turkey. The tenders of telescope and enclosure have been made and almost al...
Agile development approach for the observatory control software of the DAG 4m telescope
Gucsavd, B. Bulent; Coker, Deniz; YEŞİLYAPRAK, Cahit; KESKİN, ONUR; Zago, Lorenzo; Yerli, Sinan Kaan (2016-06-30)
Observatory Control Software for the upcoming 4m infrared telescope of DAG (Eastern Anatolian Observatory in Turkish) is in the beginning of its lifecycle. After the process of elicitation-validation of the initial requirements, we have been focused on preparation of a rapid conceptual design not only to see the big picture of the system but also to clarify the further development methodology. The existing preliminary designs for both software (including TCS and active optics control system) and hardware sh...
DAG: A New Observatory And A Prospective Observing Site For Other Potential Telescopes
YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; KESKİN, ONUR; Gucsav, B. Bulent (2016-07-01)
DAG (Eastern Anatolia Observatory is read as "Dogu Anadolu Gozlemevi" in Turkish) is the newest and largest observatory of Turkey, constructed at an altitude of 3170 m in Konakli/Erzurum province, with an optical and near-infrared telescope (4 m in diameter) and its robust observing site infrastructure. This national project consists of three main phases: DAG (Telescope, Enclosure, Buildings and Infrastructures), FPI (Focal Plane Instruments and Adaptive Optics) and MCP (Mirror Coating Plant). All these thr...
