100,000 Crab giant pulses at 215 MHz detected with an SKA-Low prototype station
M. Sokolowski, P. Kumar, S. Dhavali +4
We report detection and analysis of the largest low-frequency (200 - 231.25 MHz) sample of Crab giant pulses (GPs) reported in the literature. In total about 95000 GPs were detecte…
Probing magneto-ionic microstructure towards the Vela pulsar using a prototype SKA-Low station
C. P. Lee, N. D. R. Bhat, M. Sokolowski +2
The Vela pulsar (J0835-4510) is known to exhibit variations in Faraday rotation and dispersion on multi-decade timescales due to the changing sightline through the surrounding Vela…
Imaging pulsar census of the Galactic Plane using MWA VCS data
S. Sett, M. Sokolowski, E. Lenc +1
Traditional pulsar surveys have primarily employed time-domain periodicity searches. However, these methods are susceptible to effects like scattering, eclipses and orbital motion.…
High-Time Resolution GPU Imager for FRB searches at low radio frequencies
M. Sokolowski, G. Aniruddha, C. Di Pietrantonio +5
Fast Radio Bursts (FRBs) are millisecond dispersed radio pulses of predominately extra-galactic origin. Although originally discovered at GHz frequencies, most FRBs have been detec…
A Fast Radio Burst monitor with a Compact All-Sky Phased Array (CASPA)
R. Luo, R. D. Ekers, G. Hobbs +9
Fast Radio Bursts (FRBs) are short-duration radio transients that occur at random times in host galaxies distributed all over the sky. Large field of view instruments can play a cr…
Calibration of an SKA-Low Prototype Station Using Holographic Techniques
Jishnu N. Thekkeppattu, Randall B. Wayth, Marcin Sokolowski
Performance of digitally beamformed phased arrays relies on accurate calibration of the array by obtaining gains of each antenna in the array. The stations of the Square Kilometer…
Image-based searches for pulsar candidates using MWA VCS data
S. Sett, N. D. R. Bhat, M. Sokolowski +1
Pulsars have proven instrumental in exploring a wide variety of physics. Pulsars at low radio frequencies is crucial to further our understanding of spectral properties and emissio…
Measuring the global 21-cm signal with the MWA-I: improved measurements of the Galactic synchrotron background using lunar occultation
B. McKinley, G. Bernardi, C. M. Trott +12
We present early results from a project to measure the sky-averaged (global), redshifted cm signal from the Epoch of Reionisation (EoR), using the Murchison Widefield Array (…
Observations of Low-Frequency Radio Emission from Millisecond Pulsars and Multipath Propagation in the Interstellar Medium
N. D. R. Bhat, S. E. Tremblay, F. Kirsten +23
Studying the gravitational-wave sky with pulsar timing arrays (PTAs) is a key science goal for the Square Kilometre Array (SKA) and its pathfinder telescopes. With current PTAs rea…
Characterization of a Low-Frequency Radio Astronomy Prototype Array in Western Australia
A. T. Sutinjo, T. M. Colegate, R. B. Wayth +12
We report characterization results for an engineering prototype of a next-generation low-frequency radio astronomy array. This prototype, which we refer to as the Aperture Array Ve…
