# Low frequency spectral energy distributions of radio pulsars detected with the Murchison Widefield Array

## TL;DR

This study measures low-frequency radio spectra of 60 known pulsars using the Murchison Widefield Array, providing new flux density data between 72 and 231 MHz and comparing it with existing measurements.

## Contribution

First comprehensive low-frequency spectral energy distributions of pulsars observed with the MWA, expanding understanding of pulsar radio emission at these frequencies.

## Key findings

- Good agreement between MWA flux densities and previous measurements
- Flux densities measured across 20 frequency bands between 72 and 231 MHz
- Enhanced spectral data for 60 pulsars at low radio frequencies

## Abstract

We present low-frequency spectral energy distributions of 60 known radio pulsars observed with the Murchison Widefield Array (MWA) telescope. We searched the GaLactic and Extragalactic All-sky MWA (GLEAM) survey images for 200-MHz continuum radio emission at the position of all pulsars in the ATNF pulsar catalogue. For the 60 confirmed detections we have measured flux densities in 20 x 8 MHz bands between 72 and 231 MHz. We compare our results to existing measurements and show that the MWA flux densities are in good agreement.
