Great timing after one year!
In the system description paper we demonstrated that PSR J1909-3744 was achieving timing residuals of just 66 ns over one year.
Marisa Geyer (SARAO) discovered that the energetic pulsar J0540-6919 emits giant pulses with energy sometimes concentrated across just about 100 MHz of bandwidth and published this in ui.adsabs.harvard.edu/abs/2021MNRAS.505.4468G/abstract - this is similar to what is observed in Fast Radio Bursts.
PSR J2234+2114 became the 1500th unique pulsar target observed by MeerTime last week. In all MeerTime has observed 1502 pulsars using 1640 hours or 68 days of telescope time in its first 18 months of operations.
Welcome back PSR J1629-6902!
Over a decade after it was last observed at the Parkes radio telescope, MeerKAT observed PSR J1629-6902 as part of the millisecond pulsar census project in the Timing Array project. In just 8 minutes it came in with a S/N of 390!
In our first observation of the globular cluster Terzan 5 Ter5A was in fine form, showing its eclipse and obtaining a S/N of over 1000! Note the excess delay as it emerges from the eclipse.
On Tuesday the 12th of February 2019 MeerTime recorded data from its first official observing run. The run was an outstanding success with the telescope performing flawlessly. Observers from Australia, South Africa, Germany, Italy and Thailand watched while the first data flowed into our pulsar processor. Within minutes the data were being analysed, and outstanding signal to noise ratios were being achieved. All up we observed 18 sources. Two of the recycled pulsars are shown below, along with the residuals for J1757-5322.
Tests are continuing with the SKARAB beam-former and the results are looking great!
Timing tests on PSR J1909-3744 returned a stunning S/N ratio of 6000 in just half an hour, and an rms
timing residual of 240 nanoseconds in just 8 second integrations!
PSR J2241-5236 was in fine form overnight, producing a S/N ratio of 4300 in 600s.
MeerTime SKARAB beamformer
The SARAO staff have just made their first tests of the new beamformer! 64 dishes here we come!
