MeerKAT is a science-eager 64-dish radio telescope in the heart of the South African Karoo. This world operates at maser-coordinated "Karoo Telescope Time" - a hyper precise time standard ideal for pulsar timing science as done by the Meertime project meertime.org
See the MeerKAT PTA news now also on the University of Cape Town's website! news.uct.ac.za/article/-2024…

A year and a half on - and MeerKAT PTA results streaming in! In just 4.5 yrs of data we see evidence for the gravitational wave background. Well done team! And testament to a magnificent instrument.
A perfect day to show off our new website too: africanpulsartiming.github.i…

And there we have, the checkpoint marking the beginning of the era of nHz GW astronomy!
A successful press conference with the members and PIs of @indian_pta presenting the emerging evidence of a SGWB in the combined EPTA+InPTA data sets! 🥂🎉

Love this fantastic animation to go with today's announcement of increased hints of nanoHz GWs!
Well done to all involved @IPTA_GW @ARC_OzGRav @InPTA_GW @NANOGrav @EPTAGW
Australian astronomers have announced the strongest hint yet of low-frequency gravitational waves from supermassive black hole pairs! @Swinburne @ARC_OzGRav @CSIRO_ATNF iopscience.iop.org/article/1…
Can't wait for MeerKAT data to join the ride of this choppy wave!

In this paper we compare several data versions; it turns out that the latest EPTA data from our new-generation observing systems show non-negligible evidence for a gravitational wave background being present in our data
It's out!
We see early signs of a Gravitational Wave background in our combined dataset with @EPTAGW.
These results corroborate with those from @NANOGrav and PPTA @CSIRO_ATNF @ARC_OzGRav
Read along in this thread to know this discovery was made and it's consequences!

#Astronomy activities can change perspectives and reframe one’s problems. Can they be designed to promote #mentalhealth? That is the question being explored by Dominic Vertue, Sandra Benitez, & others at the OAD.

Excited to see a new white dwarf pulsar discovered!
This is the second only known white dwarf pulsar.

A big breakthrough in stellar research! South African telescopes have contributed to uncovering the secrets of a new type of white dwarf pulsar. These rapidly rotating stars offer valuable insights into magnetic fields and stellar companions. shorturl.at/tyIZ0🌌 #Discovery
How it all fits together - a collection of pulsar array timing experiments called the International Pulsar Timing Array jointly searches for nanoHz Gravitational Waves! More details on the science at @IPTA_GW.
And mark June 29th for the combined reporting of their new results!
