A study of 80 known pulsars at 185 MHz using MWA incoherent drift-scan observations
Ting Yu, Hongyu Gong, Zhifu Gao +4
A systematic study of 80 known pulsars observed at 185 MHz has been conducted using archival incoherent-sum data from the Murchison Widefield Array (MWA). The dataset comprises 48…
