Some exciting results!
Using MeerKAT (super sensitive telescope array) the MeerKAT Pulsar Timing Array (MPTA) team have also found supporting evidence (with their assumptions and models) of the gravitational wave background (GWB) that other Pulsar Timing Arrays (PTAs) announced last year. This is further independent verification!
The Universe rattles!
I had a chat with Dr. Matt Miles from Swinburne Uni / OzGrav about his lead-author paper and results: https://www.spaceaustralia.com/feature/mpta-finds-evidence-gravitational-wave-background
But the fun doesn't stop there! An additional paper, co-authored by Rowina Nathan, used the MPTA data to make the most detailed map of the GWB, and found an intriguing anisotropy (though, statistically, could be insignificant). If it turns out to be true it shows the GWB is not isotropic, and we could be seeing a unique system or some unknown cosmology. Rowina wrote a piece in #SpaceAustralia about this too: https://www.spaceaustralia.com/feature/mapping-gravitational-wave-universe
Very cool science that take pulsars and turn the Galaxy into a detector.

New Reads! 👀
Australian astronomers have used Murriyang (Parkes radio telescope) data to make the most precise measurements of the nearest millisecond pulsar to Earth.
This new data was then used by researchers using the NICER telescope aboard the International Space Station to help further constrain the mass, radius and equations of state of matter of the brightest millisecond pulsar in the sky.
Wrote a little article outlining these new results on #SpaceAustralia

Strange object that pulses for 2 min every 44 min discovered.
(Alt-txt: main picture shows a group of radiotelescope dishes in the desert of Australia. The southern Cross is in the background but they are pointing away from this region.
Also shows picture of region of nebulosity but unhelpfully does not define where it is. I would guess it to be somewhere in the Sagittarius or Scorpius Starfields.
Another animation shows a wildly spinning globe emitting light from its poles as a possible explanation.)#astronomy #RadioAstronomy #XRayAstronomy #AustralianSquareKilometerArray

OJ 287 bevat waarschijnlijk een dubbel superzwaar zwart gat in het centrum
Met behulp van gegevens van de 10 meter radiotelescoop RadioAstron in de ruimte en een netwerk van 27 observatoria op Aarde hebben astronomen een ongebruikelijke lintvormige jet gevonden in het centrum van OJ 287, een sterrenstels

Worth some cautious optimism in that this plan may reduce RFI that impacts radio astronomy. It is essentially a product of the @NSF Electromagnetic Spectrum Management (ESM) office, and astronomy compatibility was a top priority in its development.

The South African MeerKAT telescope is the precursor of SKA-MID. The expanded MeerKAT+ array — including more than a dozen additional SKA antennas and receivers — is part of a project funded in partnership by SARAO (@ska_africa), the Max Planck Society (@maxplanckgesellschaft), and INAF.

Have you seen it? They captured an image of a black hole and its accretion disc residing in the heart of the M87 galaxy, 52 million light years away from us. This blows my mind on multiple levels. #ESO #astronomy #M87 #black_hole #science #ALMA #radioastronomy #mindblown

I'm looking for a map of all the #radioquietzones in the world. Does such a thing exist? I suppose I could generate one if I had a list of locations with coordinates. I'm particularly interested in those located at #radioastronomy or #radioobservatory sites

Yesterday I gave my first PhD talk at the Astronomical Society of Australia’s Annual Science Meeting on my fav millisecond pulsar - PSR J1713+0747.
The pulsar that threw a tantrum!
Millisecond pulsars are used in pulsar timing arrays as they’re considered stable rotators over the long term. That is vote to helping us search for gravitational wave backgrounds - the big news that we announced last week.
But this very well know millisecond pulsar decided to undergo a massive magnetospheric reconfiguration in 2021 - only the second millisecond pulsar that we know off to exhibit this strange behavior!
In my PhD I will be exploring to see why this happened and if other millisecond pulsars might be doing this on a smaller scale. Maybe they’re not so stable after all … ask me again in three years!

"The ideal of a dark and quiet sky is one many astronomers fight to protect. ... Preservation of the night sky across the electromagnetic spectrum is an extension of the stewardship of a human environment that now goes beyond our planet and reaches toward the cosmic ocean. It is also key to the future of astronomical discoveries."

wrote this article as I found m MRes research poster from last year (I had temp. lost it during the renovations). In my research, I looked at 10 'new' pulsars for the Parkes Pulsar Timing Array project and determined their suitability to use in our searches for the nanohertz-frequency stochastic Gravitational Wave background.
Analysed their intrinsic properties, signal propagation, timing, and then simulated how much significance they add to the array when searching for gravitational waves.
