A Roadmap towards a Space-based Radio Telescope for Ultra-Low Frequency Radio Astronomy
M. J. Bentum, M. K. Verma, R. T. Rajan +10
The past two decades saw a renewed interest in low frequency radio astronomy, with a particular focus on frequencies above 30 MHz. However, at frequencies below 30 MHz, Earth-based…
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…
Near-Memory Computing: Past, Present, and Future
Gagandeep Singh, Lorenzo Chelini, Stefano Corda +5
The conventional approach of moving data to the CPU for computation has become a significant performance bottleneck for emerging scale-out data-intensive applications due to their…
Discovering the Sky at the Longest Wavelengths with Small Satellite Constellations
Xuelei Chen, Jack Burns, Leon Koopmans +29
Due to ionosphere absorption and the interference by natural and artificial radio emissions, ground observation of the sky at the decameter or longer is very difficult. This unexpl…
