The #SKAO in South Africa 'comes alive' with first fringes milestone - two of SKA-Mid's 15m-diameter dishes were used together to achieve the result, observing a radio galaxy estimated to be around 2.6 billion light years away: https://www.skao.int/en/news/693/ska-mid-milestone

Supplement to the Open Journal of Astrophysics – “Pulsar Science with the SKAO”

It’s been a busy day at the Open Journal of Astrophysics as we’ve published 12 related papers in the form of our first ever Supplement; officially it is Vol. 8 Supplement Issue 1. The idea of a Supplement is to publish a set of related papers together. I imagine it might be of interest for publishing conference proceedings, etc.

The topic of this Supplement is Pulsar Science with the Square Kilometre Array Observatory and it includes updates to the Science Case for the SKAO, the previous version of which is 10 years old. All the papers are indendependently peer-reviewed, which took some organizing and a lot of time because many potential referees are themselves members of the SKA Pulsar Science Working Group! Anyway, the final versions of all the papers hit the arXiv this morning so I published them all today.

Rather than include all 12 papers in tomorrow’s Saturday update I decided just to show the overlay for the overview of the special issue, which is here:

The following paragraph describes the content of the supplement and includes links to the other 11 papers in the issue.

The large instantaneous sensitivity, a wide frequency coverage and flexible observation modes with large number of beams in the sky are the main features of the upcoming SKA observatory’s two telescopes, the SKA-Low and the SKA-Mid, which are located on two different continents. Owing to these capabilities, the SKAO telescopes are going to be a game-changer for radio astronomy in general and pulsar astronomy in particular. The eleven articles in this special issue on pulsar science with the SKA Observatory describe its impact on different areas of pulsar science. Phase 1 of the rollout of the SKAO telescope is likely to double the known pulsar population in new surveys described in the first three papers (Keane et al. 2025Abbate et al. 2025Bagchi et al. 2025). These new discoveries will improve our understanding of the dynamics, evolution and gas content of globular clusters and the black hole at the centre of the Milky Way galaxy apart from increasing the samples for each of different kinds of radio emitting neutron stars (Levin et al. 2025). The larger population sample will enhance our understanding of the magneto-ionic interstellar medium (Tiburzi et al. 2025Xu et al. 2025), the pulsar magnetosphere (Oswald et al. 2025) and pulsar wind nebulae (Gelfand et al. 2025). Moreover, the discovery of exotic neutron star systems will test gravity theory ever more stringently (Krishnan et al. 2025) and will probe fundamental physics at sub-atomic level (Basu et al. 2025). Finally, this enhanced sample is likely to make the sky portrait sharper in nano-Hertz gravitational waves impacting on our understanding of the Universe in a fundamental way (Shannon et al. 2025). In summary, the papers in this special issue describe the way the upcoming SKA Observatory’s telescopes address fundamental physics through the study of pulsars and gravitational waves.

Deutschland bekräftigt Engagement für SKAO mit Unterzeichnung eines Großauftrags

Germany reaffirms commitment to #SKAO as major contract signed: https://www.mpifr-bonn.mpg.de/announcements/2025/8 - OHB Digital Connect will supply 86 highly sensitive receivers for the SKA-Mid radio telescope, currently under construction in South Africa’s Northern Cape; the €10.7m contract is the first to be awarded to Germany since it joined the Observatory just under a year ago.

" It is hailed as a global endeavour to explore the hidden universe – a powerful telescope comprising more than 130,000 antennae being built in outback Western Australia. But while the venture is being lauded as one of the most significant scientific endeavours of the 21st century, the Guardian can reveal that the organisation managing the funds of 16 member states has been rocked by allegations of financial misconduct."

A giant telescope was supposed to answer the universe’s big questions. Now the project has been rocked by misconduct claims

The organisation that manages the Square Kilometre Array Observatory has denied whistleblower allegations of financial mismanagement

More pulsar madness!

The ‘cosmic clocks’ preparing SKAO for early science

Observations of pulsars – rapidly spinning dead stars – are helping the SKA Observatory to prepare for science operations.

This is my second migration on Mastodon, so I think an Introduction might be in order. I'm moving in to this account (that had lived independently, to test some of Mathstodon features) after astrodon.social is being sunset. Hope that Astrodon as a concept still lives!

I currently work in Systems Engineering for radio telescopes (in particular, the ALMA radio interferometer). I’ve also worked in software development and management for the SKAO observatory, and for the archive department at ESO. Of course, I'm also very interested in math (specially that having to do with system theory), so I'll try to get a bit stronger there.

Glad to see you all around!
