Pulsar Observations at low latitudes and low frequencies

Abstract

The Pulsar Monitoring in Argentina (PuMA) is a collaboration between the Argentine Institute for Radioas-tronomy (IAR) and the Rochester Institute of Technology (RIT) that since 2017 has been observing southernsky pulsars with high cadence using the two restored IAR antennas in the L-Band (1400MHz). We brieflyreview the first set of results of this program to study transient phenomena, such as magnetars and glitchingpulsars, as well as to perform precise timing of millisecond pulsars. Access to lower frequency bands, wheremost of the pulsars are brighter, would allow us to reach additional pulsars, currently buried into the back-ground noise. We identify two dozen additional glitching pulsars that could be observable in the 400MHz bandby the IAR’s projected Multipurpose Interferometer Array (MIA). We also discuss the relevance and challengesof single-pulse pulsar timing at low frequencies and the search for Fast Radio Burst (FRB) in the collecteddata since 2017 using machine learning techniques.
