A Bizarre Pulsar Switches Between Two Brightness Modes. Astronomers Finally Figured Out Why.

Pulsars spin so predictably you could set your atomic clock to them. But one pulsar, nicknamed J1023, has puzzled astronomers because it constantly switches between two brightness modes, sometimes throwing off high-energy photons and then shifting to low mode, which beams radio waves. Astronomers knew it was orbiting another star, pulling away material, but they didn't know what was causing this change in brightness. A worldwide team of researchers directed 12 telescopes at J1023, revealing the complicated dance between the two stars that generates this odd behavior.

New tee arrived yesterday and it merges together two excellent pop culture pieces with some beautiful science.

I call it: ‘The Gravitational Wave Background’
🌊📡〰️〰️〰️🔵

Can’t wait to wear this in summer just so I can talk about the GWB to randoms.

Here’s also some words I wrote about the GWB on pre the big announcements made at end of June.

HAPPENING TONIGHT! 8pm AEST

I’ll be giving an online talk about my fav and all-round weirdo space objects - pulsars! All ages welcome and will feature some basics along with some sciencey content + a little bit about my current research.

Thanks to the Astro. Society of Victoria for this opportunity!

Event requires rego but is free. Broadcast on YouTube/FB/Twitch. Please come along if you’re free.

Forgot to share this here, but 6 August is the anniversary of the discover of by Dame Professor Jocelyn Bell Burnell.

She was looking through the roll of data from the telescope she helped build and noticed a little bit of ‘scruff’.

Her discovery changed our understanding of the Universe but sadly her male supervisor took credit and got the Nobel prize for it!

A real fascinating story of how an 81-year-old former Air Force chap had come forward to announce he saw pulsars well before they were discovered but could not talk about it for half a century until the military instruments he observed them with were decommissioned and de-classified.

In a nutshell, he was using radar for a Ballistic Missile early warning system and noticed a pulsating signal showing up in his data, which was rising 4 mins earlier each day. He asked astronomers after writing down the location, and it was the Crab Pulsar!

The woman who discovered pulsars, Dame Prof. Jocelyn Bell Burnell - agreed with his discoveries.

Sent this to our team's slack channel overnight, and my supervisor told me he and another one of our team's astronomers were the folks that the Air Force chap got in touch with!

Small world, and a nice Aussie connection!

She helped set up the UK Athena Swan programme. In 2018 she was awarded the $3 million Breakthrough Prize in Fundamental Physics for her discovery of & leadership in science. She donated money to the Institute of Physics for PhD scolarships for underrepresented people including women, ethnic minorities & refugee students in physics!

"The Parkes radio telescope Murriyang, which helped broadcast the moon landing in 1969, has played a central role in another scientific discovery.

CSIRO scientists working at Murriyang have been observing an array of nano hertz frequency pulsars for almost 20 years. They are ripples in space time [gravitational waves] that are nearly the same size as the Milky Way.

The longevity of the experiment is due to the waves being years or even decades in length." #
