On the detection of a cosmic dawn signal in the radio background
Saurabh Singh, Jishnu Nambissan T., Ravi Subrahmanyan +6
The astrophysics of cosmic dawn, when star formation commenced in the first collapsed objects, is predicted to be revealed as spectral and spatial signatures in the cosmic radio ba…
A Floating Octave Bandwidth Cone-Disc Antenna for Detection of Cosmic Dawn
Agaram Raghunathan, Ravi Subrahmanyan, N. Udaya Shankar +9
The critical component of radio astronomy radiometers built to detect redshifted 21-cm signals from Cosmic Dawn is the antenna element. We describe the design and performance of an…
SARAS 3 CD/EoR Radiometer: Design and Performance of the Receiver
Jishnu Nambissan T., Ravi Subrahmanyan, R. Somashekar +6
SARAS is an ongoing experiment aiming to detect the redshifted global 21-cm signal expected from Cosmic Dawn (CD) and the Epoch of Reionization (EoR). Standard cosmological models…
