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…
Investigating the multiwavelength behaviour of the flat spectrum radio quasar CTA 102 during 2013-2017
F. D'Ammando, C. M. Raiteri, M. Villata +94
We present a multiwavelength study of the flat-spectrum radio quasar CTA 102 during 2013-2017. We use radio-to-optical data obtained by the Whole Earth Blazar Telescope, 15 GHz dat…
The C-Band All-Sky Survey (C-BASS): Total intensity point-source detection over the northern sky
R. D. P. Grumitt, Angela C. Taylor, Luke Jew +14
We present a point-source detection algorithm that employs the second order Spherical Mexican Hat wavelet filter (SMHW2), and use it on C-BASS northern intensity data to produce a…
Resolved observations at 31 GHz of spinning dust emissivity variations in Oph
Carla Arce-Tord, Matias Vidal, Simon Casassus +9
The Oph molecular cloud is one of the best examples of spinning dust emission, first detected by the Cosmic Background Imager (CBI). Here we present 4.5 arcmin observations wit…
The presence of interstellar scintillation in the 15 GHz interday variability of 1158 OVRO-monitored blazars
J. Y. Koay, D. L. Jauncey, T. Hovatta +8
We have conducted the first systematic search for interday variability in a large sample of extragalactic radio sources at 15 GHz. From the sample of 1158 radio-selected blazars mo…
125-211 GHz Low Noise MMIC Amplifier Design for Radio Astronomy
Daniel White, William McGenn, Danielle George +5
To achieve the low noise and wide bandwidth required for millimeter wavelength astronomy applications, superconductor-insulator-superconductor (SIS) mixer based receiver systems ha…
