A Statistical Analysis of Crab Pulsar Giant Pulse Rates

Graham M. Doskoch, Andrea Basuroski, Kriisa Halley +18

A small number of pulsars are known to emit giant pulses, single pulses much brighter than average. Among these is PSR J0534+2200, also known as the Crab pulsar, a young pulsar wit…

Accretion Funnel Reconfiguration during an Outburst in a Young Stellar Object: EX Lupi

Koshvendra Singh, Joe P. Ninan, Marina M. Romanova +14

EX Lupi, a low-mass young stellar object, went into an accretion-driven outburst in March of 2022. The outburst caused a sudden phase change of ~ 112 5 in…
