SMIRF is an observing mode developed at UTMOST which performing simultaneous pulsar timing, transient searching and pulsar searching observations.
The primary science driver is to be able to perform repeat, rapid surveys of the Galactic plane searching for both one-off and periodic transient events while timing the pulsars in survey pointings. The large field of view of UTMOST (8 square degrees) leads to high survey speeds (e.g. the Southern Galactic plane could be surveyed with 15 minute pointings in approximately a week).
This capacity is well suited to probing pulsar intermittency and any fast transient population of the galaxy over timescales of days to months.
SMIRF was developed by PhD student Vivek Venkatraman Krishnan (now a postdoc at MPIA Bonn).
