African Pulsar Timing | APT

On the road to finding and analysing Gravitational Waves using Pulsar Timing Array techniques on our African MeerKAT telescope & with the Meertime collaboration

[African Pulsar Timing | APT @APT_GW]

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 https://t.co/54RdKns91h

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: https://t.co/9rIrOjJMBv

Watch Dr Daniel Reardon (@Swinburne) explain how #ParkesPulsarTimingArray astronomers used the @CSIRO_ATNF Parkes radio telescope #Murriyang to find evidence for gravitational waves from supermassive black holes at the heart of galaxies https://t.co/pu96EkUuVh

[LIGO India @LIGOIndia]

LIGO-India joins LIGO-India Scientific Collaboration in congratulating colleagues from @InPTA_GW, along with @IPTA_GW members @NANOGrav, @EPTAGW, PPTA @CSIRO_ATNF, @APT_GW and CPTA on opening a new window to low-frequency #GravitationalWaves!

[African Pulsar Timing | APT @APT_GW]

Join us for the IAU 389 Symposium on Gravitational Waves in Aug 2024 in Cape Town, South Africa - where we will discuss the latest PTA results and much more!

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! 🥂🎉

[Samaya Nissanke (she/her) 🕊️❤️ @samayanissanke]

Wow, just wow! Good morning humming cosmos! Congratulations to all my amazing colleagues & PTAs across the world for this beautiful first result after decades of your hard work, delighted & so proud to know you! @IPTA_GW @NANOGrav @EPTAGW @CSRIO_ATNF @InPTA_GW @APT_GW 🙌🏾❤️🎉📡🌍

[African Pulsar Timing | APT @APT_GW]

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

[African Pulsar Timing | APT @APT_GW]

Can't wait for MeerKAT data to join the ride of this choppy wave!

News is already out Australian side!

[European Pulsar Timing Array @EPTAGW]

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

[African Pulsar Timing | APT @APT_GW]

It's out!

[InPTA @InPTA_GW]

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!

[African Pulsar Timing | APT @APT_GW]

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

[OzGrav @ARC_OzGRav]

Australian astronomers have announced the strongest hint yet of low-frequency gravitational waves from supermassive black hole pairs! @Swinburne @ARC_OzGRav @CSIRO_ATNF https://t.co/e9uKi3fWWT

[African Pulsar Timing | APT @APT_GW]

Looking forward to this already! Find more conference details as they become available at https://t.co/XOIU3401cJ

[IAU GA 2024 🌍 @astronomy2024]

An exciting pulsar timing announcement is coming on 29 June! Join us at the IAU Symposium on Gravitational Wave Astrophysics in Cape Town, 6-8 Aug 2024! Explore impactful discoveries in Physics & Astronomy, discuss GW detections and more! #GW2024 @APT_GW https://t.co/k8Vd6cjX4N

[IAU-OAD @Astro4Dev]

#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.

[NRF|SAAO @SAAO]

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. https://t.co/1uZwEbyGJF🌌 #Discovery

[African Pulsar Timing | APT @APT_GW]

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!

[International Pulsar Timing Array @IPTA_GW]

The International Pulsar Timing Array (IPTA) is a consortium of consortia, comprised of the European PTA (EPTA), the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), the Indian Pulsar Timing Array Project (InPTA), and the Parkes PTA (PPTA).
