A Multiwavelength Study of a Long-Duration VHE Flare from BL Lacertae with VERITAS
Atreya Acharyya, Avery Archer, Priyadarshini Bangale +72
We report the first observations of a long-duration very-high-energy (VHE; GeV) flare from BL Lacertae (VER J2202+422), taken with the Very Energetic Radiation Imaging Te…
A Multiwavelength Interpretation of HESS J1857+026 Emission Using the Fermi-LAT, VERITAS, and HAWC Observatories
Jordan Eagle, Yu Chen, Ramiro Torres-Escobedo +2
We present a new study on the MeV-TeV gamma-ray origin of HESS J1857+026 using data collected from the Fermi-LAT, VERITAS, and HAWC observatories. A spatial and spectral study of H…
Surface Interactions in Photon Monte Carlo Simulations
J. R. Peterson, D. Valls-Gabaud, A. Dutta +2
We implement a comprehensive simulation of photon surface interactions using a Monte Carlo approach. This is effective in simulating the interaction of light with telescope mirrors…
Weak lensing analysis of A115, A2219 and A2261: Detection of galaxy groups and filaments around clusters
Anirban Dutta, John Peterson, Matteo Cianfaglione +1
We present a weak lensing and multi-wavelength analysis of three galaxy clusters: A115, A2219, and A2261. Weak lensing is performed using shape measurements made in short 60s expos…
Weak Lensing analysis of Abell 2390 using short exposures
A. Dutta, J. R. Peterson, T. Rose +4
We present a weak lensing analysis of the galaxy cluster Abell 2390 at z = 0.23 using second moment shape measurements made in 411 short 60s exposures. The exposures are obtained i…
Forced Measurement of Astronomical Sources at Low Signal to Noise
Anirban Dutta, John R. Peterson, Glenn Sembroski
We propose a modified moment matching algorithm to avoid catastrophic failures for sources with a low signal to noise ratio (SNR). The proposed modifications include a method to el…
Self-Consistent Atmosphere Representation and Interaction in Photon Monte Carlo Simulations
J. R. Peterson, G. Sembroski, A. Dutta +1
We present a self-consistent representation of the atmosphere and implement the interactions of light with the atmosphere using a photon Monte Carlo approach. We compile global cli…
Deformation of Optics for Photon Monte Carlo Simulations
J. R. Peterson, E. Peng, C. J. Burke +2
We develop a comprehensive approach to simulate the deformation of mirrors and lenses due to thermal and mechanical stresses that couples efficiently to photon-based optics simulat…
