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.

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...
Image formation model for photon sieves
Öktem, Sevinç Figen; Kamalabadi, Farzad (2013-09-15)
A photon sieve, modification of a Fresnel zone plate, has been recently proposed to achieve higher resolution imaging and spectroscopy at UV and x-ray wavelengths. In this paper, we present Fresnel imaging formulas that relate the output of a photon sieve imaging system to its input, originating from either a coherent or incoherent extended source. By using a well-known model for the zone plate, we also provide approximations to these imaging formulas, which are more efficient to compute. These imaging rela...
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...
Overview of the beam emission spectroscopy diagnostic system on the National Spherical Torus Experiment
Smith, D. R.; Feder, H.; Feder, R.; Fonck, R. J.; Labik, G.; McKee, G. R.; Schoenbeck, N.; Stratton, B. C.; Uzun Kaymak, İlker Ümit; Winz, G. (AIP Publishing, 2010-10-01)
A beam emission spectroscopy (BES) system has been installed on the National Spherical Torus Experiment (NSTX) to study ion gyroscale fluctuations. The BES system measures D-alpha emission from a deuterium neutral heating beam. The system includes two optical views centered at r/a approximate to 0.45 and 0.85 and aligned to magnetic field pitch angles at the neutral beam. f/1.5 collection optics produce 2-3 cm spot sizes at the neutral beam. The initial channel layout includes radial arrays, poloidal arrays...
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...
