Description
Recent radio surveys have demonstrated that the radio sky is far more dynamic and variable than previously thought, with a host of new transient discoveries rapidly following wide-area surveys conducted with SKA precursors such as LOFAR, ASKAP, and the MWA. In particular, the long-period radio transients (LPTs) have motivated searches of the time domain between seconds to hours, a timescale historically understudied.
In this talk I describe a high-cadence monitoring survey covering the entire Galactic Plane south of Declination +30 degrees, using the MWA at 200MHz. Covering timescales from four seconds to three years, this survey has enabled the discovery of three LPTs, five pulsars, 20 new supernova remnants, and has contributed measurements to a host of other projects, including ASKAP-selected LPTs, studies of eclipsing binary millisecond pulsars, and new Galactic Centre Radio Transients.
Low-frequency surveys offer a multitude of benefits, but also challenges, and I will describe our solutions, along with future upgrades that will enable an even larger discovery space. I will conclude with an outlook on the future of low-frequency monitoring of the Galactic plane, both in the medium-term, and once the SKA-Low arrives.
