50-250 MHz Pulsar Census with an SKA-Low prototype station: Spectra and Polarization
Pratik Kumar, Marcin Sokolowski, Randall Wayth
Low-frequency pulsar observations are crucial for understanding pulsar emission spectra and population physics, as well as for probing the interstellar medium (ISM) and Earth's ion…
Pulsar B1237+25 Aberration/Retardation Analysis from Decimeter to Decameter Wavelength: Challenge to "Radius-to-Frequency Mapping"
Joanna M. Rankin, Vyacheslav Zakharenko, Oleg Ulyanov +9
PSR B1237+25 is perhaps the canonical example of a pulsar with a core/double cone profile. Moreover, it is bright with little spectral turnover, and its profile perhaps uniquely re…
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…
A Multifrequency Census of 100 Pulsars below 100 MHz with LWA: A Systematic Study of Flux Density, Spectra, Timing, Dispersion, Polarization, and Its Variation from a Decade of Observations
Pratik Kumar, Greg B. Taylor, Kevin Stovall +2
We present a census of 100 pulsars, the largest below 100 MHz, including 94 normal pulsars and six millisecond pulsars, with the Long Wavelength Array (LWA). Pulse profiles are det…
