By: Liam Connor and Robert Main

(Image Credit: Andre Recnik; Click to enlarge) The first VLBI image of a pulsar’s scattering screen revealed a linear structure in the sky. This is believed to possibly due to refraction at grazing incidence of current sheets in the ISM, where ripples in the sheets cause an enhanced bending of the light from the pulsar. Analogously, a star’s light along t…

Prof. Pen and team Pioneer Project to Image Pulsars with Unprecedented Resolution

 Pen and his team – including CITA post-doc Richard Shaw, U of T summer students Anita Bahmanyar, Natalie Price-Jones and Philip Isaac, Dunlap Institute Professor Keith Vanderlinde, and DAA Professor Marten van Kerwijk on the most recent observing run – is employing the Algonquin Radio Observatory, a 46-metre radio antenna built deep in Algonquin Park beginning in 1959, and a technique the ARO…
