Discovery and confirmation plots of three new pulsars in the Large Magellanic Cloud. Top row: discovery observations of PSRs J0520−67, J0541−68, and J0543−67, with the integrated pulse profile (top subpanel) and frequency–phase diagnostic plot (bottom subpanel). Bottom row: a confirmation of PSR J0520−67 in a neighboring beam (left) and J0541−68 with the Parkes UWL receiver spanning 704–4032 MHz (middle). Since PSR J0543−67 was not redetected, we instead show its time–phase plot as further evidence of its authenticity (right). "arb." denotes "arbitrary units."
