First M87 Event Horizon Telescope Results. III. Data Processing and Calibration
The Event Horizon Telescope Collaboration
We present the calibration and reduction of Event Horizon Telescope (EHT) 1.3mm radio wavelength observations of the supermassive black hole candidate at the center of the radio ga…
Concerns about Modelling of the EDGES Data
Richard Hills, Girish Kulkarni, P. Daniel Meerburg +1
It is predicted that the spectrum of radio emission from the whole sky should show a dip arising from the action of the light from the first stars on the hydrogen atoms in the surr…
Wavelet-Based Characterization of Small-Scale Solar Emission Features at Low Radio Frequencies
Akshay Suresh, Rohit Sharma, Divya Oberoi +36
Low radio frequency solar observations using the Murchison Widefield Array have recently revealed the presence of numerous weak, short-lived and narrow-band emission features, even…
Power spectrum analysis of ionospheric fluctuations with the Murchison Widefield Array
Shyeh Tjing Loi, Cathryn M. Trott, Tara Murphy +45
Low-frequency, wide field-of-view (FoV) radio telescopes such as the Murchison Widefield Array (MWA) enable the ionosphere to be sampled at high spatial completeness. We present th…
A Digital-Receiver for the Murchison Widefield Array
Thiagaraj Prabu, K. S. Srivani, D. Anish Roshi +55
An FPGA-based digital-receiver has been developed for a low-frequency imaging radio interferometer, the Murchison Widefield Array (MWA). The MWA, located at the Murchison Radio-ast…
Radiometric Measurements of Electron Temperature and Opacity of Ionospheric Perturbations
Alan E. E. Rogers, Judd D. Bowman, Juha Vierinen +2
Changes in the sky noise spectrum are used to characterize perturbations in the ionosphere. Observations were made at the same sidereal time on multiple days using a calibrated bro…
