The illustration shows a pulsar (red sphere) and its strong magnetic field (yellow lines). As the stellar remnant rotates, narrow beams of radio waves (cones) from its poles sweep across the sky and become detectable as regular signals for observers on Earth. The new study suggests that beams may also arise from a region farther out along a 'current sheet'.

Australasian “Orange” Pulsar Workshop 2026

February 17, 2026

Overview The Australasian “Orange” Pulsar Meeting is a fortnightly telecon, supplemented by occasional in‑person workshops, for the Australasian pulsar and FRB community that fosters collaboration between theorists, modellers, and observers. […]

A bright band crosses a grid diagonally from top right to bottom left. A small dot to the right of it is marked out as PSR J1744-2946. A shadow around this dot is in the shape of a sunfish.
