In this seminar, our speaker, Ross Burns (RIKEN Cluster for Pioneering Research) will talk about “VLBI observations of maser flares”.

Abstract:
The recent years has seen an increased interest in maser flare behaviour, partially driven by the realisation that some of these events trace bursts of accretion in high-mass protostars. Radio frequency maser emission is bright and readily observable by common radio telescopes, enabling flux monitoring for a large number of sources and opening also the possibility of conducting VLBI observations. The Maser Monitoring Organisation routinely searches for, and performs follow-up observations of maser flares using VLBI and various other observational approaches. In this Seminar the findings of VLBI follow-up observations of maser flares will be presented, showing that an unexpectedly wide variety of causes for maser flaring behaviour must be considered.
