Multiband variability studies and novel broadband SED modeling of Mrk 501 in 2009
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +290
We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1 which inc…
The analysis of VERITAS muon images using convolutional neural networks
Qi Feng, Tony T. Y. Lin
Imaging atmospheric Cherenkov telescopes (IACTs) are sensitive to rare gamma-ray photons, buried in the background of charged cosmic-ray (CR) particles, the flux of which is severa…
A search for spectral hysteresis and energy-dependent time lags from X-ray and TeV gamma-ray observations of Mrk 421
A. U. Abeysekara, S. Archambault, A. Archer +220
Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at di…
Very High-Energy Gamma-Ray Follow-Up Program Using Neutrino Triggers from IceCube
IceCube Collaboration, M. G. Aartsen, K. Abraham +537
We describe and report the status of a neutrino-triggered program in IceCube that generates real-time alerts for gamma-ray follow-up observations by atmospheric-Cherenkov telescope…
A Search for Very High-Energy Gamma Rays from the Missing Link Binary Pulsar J1023+0038 with VERITAS
E. Aliu, S. Archambault, A. Archer +82
The binary millisecond radio pulsar PSR J1023+0038 exhibits many characteristics similar to the gamma-ray binary system PSR B1259--63/LS 2883, making it an ideal candidate for the…
Very-high-energy observations of the binaries V 404 Cyg and 4U 0115+634 during giant X-ray outbursts
A. Archer, W. Benbow, R. Bird +62
Transient X-ray binaries produce major outbursts in which the X-ray flux can increase over the quiescent level by factors as large as . The low-mass X-ray binary V 404 Cyg an…
Discovery of Very High Energy Gamma Rays from 1ES 1440+122
VERITAS Collaboration, S. Archambault, A. Archer +87
The BL Lacertae object 1ES 1440+122 was observed in the energy range from 85 GeV to 30 TeV by the VERITAS array of imaging atmospheric Cherenkov telescopes. The observations, taken…
Very High Energy outburst of Markarian 501 in May 2009
E. Aliu, S. Archambault, A. Archer +108
The very high energy (VHE; E 100 GeV) blazar Markarian 501 was observed between April 17 and May 5 (MJD 54938--54956), 2009, as part of an extensive multi-wavelength campaign f…
VERITAS and Multiwavelength Observations of the BL Lacertae Object 1ES 1741+196
VERITAS Collaboration, A. U. Abeysekara, S. Archambault +85
We present results from multiwavelength observations of the BL Lacertae object 1ES 1741+196, including results in the very-high-energy -ray regime using the Very Energetic Radia…
Upper limits from five years of blazar observations with the VERITAS Cherenkov telescopes
S. Archambault, A. Archer, W. Benbow +78
Between the beginning of its full-scale scientific operations in 2007 and 2012, the VERITAS Cherenkov telescope array observed more than 130 blazars; of these, 26 were detected as…
TeV Gamma-ray Observations of The Galactic Center Ridge By VERITAS
A. Archer, W. Benbow, R. Bird +73
The Galactic Center Ridge has been observed extensively in the past by both GeV and TeV gamma-ray instruments revealing a wealth of structure, including a diffuse component as well…
A Search for Brief Optical Flashes Associated with the SETI Target KIC 8462852
A. U. Abeysekara, S. Archambault, A. Archer +78
The F-type star KIC 8462852 has recently been identified as an exceptional target for SETI (search for extraterrestrial intelligence) observations. We describe an analysis methodol…
Exceptionally bright TeV flares from the binary LS I +61 303
VERITAS Collaboration, S. Archambault, A. Archer +86
The TeV binary system LS I +61 303 is known for its regular, non-thermal emission pattern which traces the orbital period of the compact object in its 26.5 day orbit around…
