GPU-Powered Coherent Beamforming
Alessio Magro, Kristian Zarb Adami, Jack Hickish
GPU-based beamforming is a relatively unexplored area in radio astronomy, possibly due to the assumption that any such system will be severely limited by the PCIe bandwidth require…
GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
Suitability of NVIDIA GPUs for SKA1-Low
Alessio Magro, Kristian Zarb Adami, Steve Ord
In this memo we investigate the applicability of NVIDIA Graphics Processing Units (GPUs) for SKA1-Low station and Central Signal Processing (CSP)-level processing. Station-level pr…
MITEoR: A Scalable Interferometer for Precision 21 cm Cosmology
Haoxuan Zheng, Max Tegmark, Victor Buza +34
We report on the MIT Epoch of Reionization (MITEoR) experiment, a pathfinder low-frequency radio interferometer whose goal is to test technologies that improve the calibration prec…
Strong lensing as a test for Conformal Weyl Gravity
Deandra Cutajar, Kristian Zarb Adami
Conformal Weyl Gravity (CWG) predicts galactic rotation curves without invoking dark matter. This makes CWG an interesting candidate theory as an alternative to GR. This removal of…
Implementation of a Direct-Imaging and FX Correlator for the BEST-2 Array
Griffin Foster, Jack Hickish, Alessio Magro +2
A new digital backend has been developed for the BEST-2 array at Radiotelescopi di Medicina, INAF-IRA, Italy which allows concurrent operation of an FX correlator, and a direct-ima…
