more TRAnsients and Pulsars

What is MeerTRAP?

MeerTRAP is a project to continuously use the MeerKAT radio telescope to search the radio sky for pulsars and fast radio transients and to rapidly and accurately locate them. Utilising the excellent sensitivity and sky coverage of MeerTRAP the team will discover many rare and scientifically important pulsar types: relativistic binaries, intermittent emitters, and transitioning systems. Current radio telescopes have only explored the tip of the transients "iceberg" and MeerTRAP will transform our knowledge of these manifestations of extreme physics. It will detect hundreds of new bursts, which will all be well localised, allowing us to identify hosts and distances, greatly enhancing their use as cosmological probes. Localisation also enables measurement of their true fluxes, polarisation, and spectral indices; all of which are crucial to identify their origin. To achieve this we are designing, implementing, and exploiting state-of-the-art hardware and software. We will also use the MeerLICHT optical telescope, which will track MeerKAT, to give us a crucial glimpse of the optical sky immediately before and after any radio transient to further constrain their origin and the associated physics.

Real time transient detection

The MeerTRAP pipeline will detect fast radio transients, such as fast radio bursts, RRATs, and pulsars, in real-time.

Transient localisation

Once a transient has been detected it can be rapidly localised using imaging. This enables rapid follow-up with MeerLICHT and other telescopes.

MeerLICHT partnership

MeerTRAP is partnered with the MeerLICHT optical telescope, a fully robotic telescope that co-points with MeerKAT. This is essential for identifying optical counterparts of fast radio transients, particularly fast radio bursts.


MeerTRAP detects FRB121102

10.09.2019 - The MeerTRAP team detects 12 bursts from FRB121102

The detection plot of one of the bursts from the repeating fast radio burst FRB121102, as seen by our MeerTRAP team after the real time detection of the burst. The top plot shows the frequency time plot, and the bottom plot shows the dedispersed burst profile.

We’re excited to announce that we have been involved in the detection of bursts from the first repeating fast radio burst, FRB 121102!

Recently, it was reported by various facilities that FRB 121102 was active, so we took the opportunity (as part of a MeerKAT DDT proposal) to observe the source early on the morning of the 10th of September. We used the MeerTRAP real-time pulse detection pipeline and backend, with the Max Planck Institute for Radio Astronomy beam former, to search for bursts in real-time for three hours.

Check out the ATel announcing our detection of 12 bursts from FRB 121102 in real-time in the three hours of observing.
