Snapshot Averaged Matrix Pencil Method (SAM) For Direction of Arrival Estimation
Harsha A. Tanti, Abhirup Datta, S. Ananthakrishnan
The estimation of the direction of electromagnetic (EM) waves from a radio source using electrically short antennas is one of the challenging problems in the field of radio astrono…
Synthetic Observations with the Square Kilometre Array (SKA) -- development towards an end-to-end pipeline
Aishrila Mazumder, Abhirup Datta, Mayuri Sathyanarayana Rao +4
Detection of the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn and the Epoch of Reionization is one of the final frontiers of modern observational cosmology. The…
Plans for building a prototype SKA regional centre in India
Yogesh Wadadekar, Dipankar Bhattacharya, Abhirup Datta +2
In order to deliver the full science potential of the Square Kilometer Array (SKA) telescope, several SKA Regional Centres (SRCs) will be required to be constructed in different SK…
Study of the equatorial ionosphere using the Giant Metrewave Radio Telescope (GMRT) at sub-GHz frequencies
Sarvesh Mangla, Abhirup Datta
Radio interferometers, which are designed to observe astrophysical objects in the universe, can also be used to study the Earth's ionosphere. Radio interferometers like the Giant M…
Peering into the Dark (Ages) with Low-Frequency Space Interferometers
Leon Koopmans, Rennan Barkana, Mark Bentum +28
Neutral hydrogen pervades the infant Universe, and its redshifted 21-cm signal allows one to chart the Universe. This signal allows one to probe astrophysical processes such as the…
A Space-Based Observational Strategy for Characterizing the First Stars and Galaxies Using the Redshifted 21-cm Global Spectrum
Jack O. Burns, Richard Bradley, Keith Tauscher +19
The redshifted 21-cm monopole is expected to be a powerful probe of the epoch of the first stars and galaxies (). The global 21-cm signal is sensitive to the thermal and i…
Trajectory Design From GTO To Lunar Equatorial Orbit For The Dark Ages Radio Explorer (DARE) Spacecraft
Anthony L. Genova, Fan Yang Yang, Andres Dono Perez +6
The trajectory design for the Dark Ages Radio Explorer (DARE) mission con-cept involves launching the DARE spacecraft into a geosynchronous transfer orbit (GTO) as a secondary payl…
