Eliminating artefacts in Polarimetric Images using Deep Learning
Dhruv Paranjpye, Ashish Mahabal, A. N. Ramaprakash +5
Polarization measurements done using Imaging Polarimeters such as the Robotic Polarimeter are very sensitive to the presence of artefacts in images. Artefacts can range from intern…
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…
Milliarcsecond Core Size Dependence of the Radio Variability of Blazars
Po Chih Hsu, Jun Yi Koay, Satoki Matsushita +6
Studying the long-term radio variability (timescales of months to years) of blazars enables us to gain a better understanding of the physical structure of these objects on sub-pars…
Tomography of the Cosmic Dawn and Reionization Eras with Multiple Tracers
Tzu-Ching Chang, Angus Beane, Olivier Dore +41
The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a c…
Observations of Galactic star-forming regions with the Cosmic Background Imager at 31 GHz
Constantinos Demetroullas, Clive Dickinson, Dimitrios Stamadianos +6
Studies of the diffuse Galactic radio emission are interesting both for better understanding the physical conditions in our Galaxy and for minimising the contamination in cosmologi…
VERITAS discovery of very high energy gamma-ray emission from S3 1227+25 and multiwavelength observations
Atreya Acharyya, Colin Adams, Avery Archer +68
We report the detection of very high energy gamma-ray emission from the blazar S3 1227+25 (VER J1230+253) with the Very Energetic Radiation Imaging Telescope Array System (VERITAS)…
