We present a study of the spectral properties of 441 pulsars observed with the Parkes radio
telescope near the centre frequencies of 728, 1382 and 3100 MHz. The observations at 728 …

We present an overview of the LOFAR Tied-Array All-Sky Survey (LOTAAS) for radio pulsars
and fast transients. The survey uses the high-band antennas of the LOFAR Superterp, the …

The radio spectral index is a powerful probe for classifying cosmic radio sources and
understanding the origin of the radio emission. Combining data at 147 MHz and 1.4 GHz …

The Variables and Slow Transients Survey (VAST) on the Australian Square Kilometre Array
Pathfinder (ASKAP) is designed to detect highly variable and transient radio sources on …

We present a sample of 1483 sources that display spectral peaks between 72 MHz and 1.4
GHz, selected from the GaLactic and Extragalactic All-sky Murchison Widefield Array …

We present an overview of the Southern-sky MWA Rapid Two-metre (SMART) pulsar survey
that exploits the Murchison Widefield Array's large field of view and voltage-capture system …

Nonrelativistic axions can be efficiently produced in the polar caps of pulsars, resulting in the
formation of a dense cloud of gravitationally bound axions. Here, we investigate the interplay …

Context. Interstellar scintillation (ISS) of pulsar emission can be used both as a probe of the
ionized interstellar medium (IISM) and cause corruptions in pulsar timing experiments. Of …

We present techniques developed to calibrate and correct Murchison Widefield Array low-
frequency (72–300 MHz) radio observations for polarimetry. The extremely wide field-of …

PSR B0950+ 08 is a bright nonrecycled pulsar whose single-pulse fluence variability is
reportedly large. Based on observations at two widely separated frequencies, 55 MHz …
