Discovery of TeV Gamma-ray Emission from CTA 1 by VERITAS
E. Aliu, S. Archambault, T. Arlen +88
We report the discovery of TeV gamma-ray emission coincident with the shell-type radio supernova remnant (SNR) CTA 1 using the VERITAS gamma-ray observatory. The source, VER J0006+…
Rapid TeV Gamma-Ray Flaring of BL Lacertae
T. Arlen, T. Aune, M. Beilicke +83
We report on the detection of a very rapid TeV gamma-ray flare from BL Lacertae on 2011 June 28 with the Very Energetic Radiation Imaging Telescope Array System (VERITAS). The flar…
The Imprint of The Extragalactic Background Light in the Gamma-Ray Spectra of Blazars
LAT Collaboration
The light emitted by stars and accreting compact objects through the history of the Universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of t…
VERITAS Observations of Six Bright, Hard-Spectrum Fermi-LAT Blazars
E. Aliu, S. Archambault, T. Arlen +84
We report on VERITAS very-high-energy (VHE; E>100 GeV) observations of six blazars selected from the Fermi Large Area Telescope First Source Catalog (1FGL). The gamma-ray emission…
Search for a correlation between very-high-energy gamma rays and giant radio pulses in the Crab pulsar
E. Aliu, S. Archambault, T. Arlen +87
We present the results of a joint observational campaign between the Green Bank radio telescope and the VERITAS gamma-ray telescope, which searched for a correlation between the em…
Constraints on Cosmic Rays, Magnetic Fields, and Dark Matter from Gamma-Ray Observations of the Coma Cluster of Galaxies with VERITAS and Fermi
T. Arlen, T. Aune, M. Beilicke +81
Observations of radio halos and relics in galaxy clusters indicate efficient electron acceleration. Protons should likewise be accelerated, suggesting that clusters may also be sou…
Multiwavelength observations of the AGN 1ES 0414+009 with VERITAS, Fermi-LAT, Swift-XRT, and MDM
E. Aliu, S. Archambault, T. Arlen +85
We present observations of the BL Lac object 1ES 0414+009 in the >200 GeV gamma-ray band by the VERITAS array of Cherenkov telescopes. 1ES 0414+009 was observed by VERITAS between…
GeV Observations of Star-forming Galaxies with \textit{Fermi} LAT
Fermi LAT Collaboration, M. Ackermann, M. Ajello +127
Recent detections of the starburst galaxies M82 and NGC 253 by gamma-ray telescopes suggest that galaxies rapidly forming massive stars are more luminous at gamma-ray energies comp…
The Fermi Large Area Telescope On Orbit: Event Classification, Instrument Response Functions, and Calibration
LAT Collaboration
The Fermi Large Area Telescope (Fermi-LAT, hereafter LAT), the primary instrument on the Fermi Gamma-ray Space Telescope (Fermi) mission, is an imaging, wide field-of-view, high-en…
VERITAS Observations of the Nova in V407 Cygni
E. Aliu, S. Archambault, T. Arlen +92
We report on very high energy (E > 100 GeV) gamma-ray observations of V407 Cygni, a symbiotic binary that underwent a nova outburst producing 0.1-10 GeV gamma rays during 2010 Marc…
Discovery of High-energy and Very High Energy Gamma-ray Emission from the Blazar RBS 0413
VERITAS Collaboration, E. Aliu, S. Archambault +93
We report on the discovery of high-energy (HE; E > 0.1 GeV) and very high-energy (VHE; E > 100 GeV) gamma-ray emission from the high-frequency-peaked BL Lac object RBS 0413. VERITA…
VERITAS Deep Observations of the Dwarf Spheroidal Galaxy Segue 1
E. Aliu, S. Archambault, T. Arlen +90
The VERITAS array of Cherenkov telescopes has carried out a deep observational program on the nearby dwarf spheroidal galaxy Segue 1. We report on the results of nearly 48 hours of…
Constraining the High-Energy Emission from Gamma-ray Bursts with Fermi
LAT Collaboration, GBM Collaboration
We examine 288 GRBs detected by the Fermi Gamma-ray Space Telescope's Gamma-ray Burst Monitor (GBM) that fell within the field-of-view of Fermi's Large Area Telescope (LAT) during…
IACT observations of gamma-ray bursts: prospects for the Cherenkov Telescope Array
Rudy C. Gilmore, Aurelien Bouvier, Valerie Connaughton +4
Gamma rays at rest frame energies as high as 90 GeV have been reported from gamma-ray bursts (GRBs) by the Fermi Large Area Telescope (LAT). There is considerable hope that a confi…
