Our fourth LIGO @egovirgo.bsky.social KAGRA observing run has now drawn to a close. We will be busy analysing data for a while to come—watch out for more discovery announcements. We will be back next year observing.docs.ligo.org/plan/

Mirror, mirror, reflecting our [LASER] beam... What is the loudest [gravitational wave] signal that we've seen? It’s #GW250114! (Yes, it’s been two weeks since it was announced, but I can still celebrate! 🎉 ) #EinsteinWasRight #HawkingWasRight @ligo.org @egovirgo.bsky.social

Occupation: Student'nt Thanks @pinkastrophysicist.bsky.social for making me the delicious cake and taking this photo of me being equally excited and terrified 5 minutes after submitting my PhD 🥰🎂🧑‍🎓

Front page news! 📰 Monash PhD researcher Christian Adamcwicz leads new LVK results revealing the mysterious 40 M☉ gap in black hole populations. Exciting clues about how the universe’s heaviest stars live and die! #BlackHoles #LVK #Astrophysics www.theaustralian.com.au/science/grav...

Results from the first part of our fourth LIGO @egovirgo.bsky.social KAGRA observing run are out today! We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars 📰 arxiv.org/abs/2508.18082 🔭🧪⚛️☄️ #GWTC4

Congrats to everyone in the LVK collaboration who worked so hard to get these exciting results out 🤩🧪🔭

The gang are all here! Today we resumed our fourth observing run with LIGO Hanford, LIGO Livingston, Virgo, KAGRA and GEO all observing together! You can check detector status live at online.ligo.org ☄️🔭🧪

Did you know NASA science is facing a 50% budget cut??? Please read this @astrobites.bsky.social post to learn more about it and what you can do astrobites.org/2025/04/15/h...

Publication day! With @sarinastro.bsky.social , Eric Howell, @plasky.bsky.social and Eric Thrane, we explore a hypothetical coincident neutron star-black hole merger and fast radio burst. We hope this work helps pave the way for future multimessenger detections! 🔭🧪⚛️ journals.aps.org/prd/abstract...

Oh wow, this is *such* a cool concept - a 'game' procedurally generated from Wikipedia, in which you can literally traverse all of human knowledge and walk down rabbit holes

I made this the other night while procrastinating, mainly because I thought all the posts about the blackout were boring. It feels like there is momentum bringing people together!

The best dark sky in the world - the Atacama Desert in Chile, which hosts many @eso.org telescopes - is under threat from an industrial project. 🔭 Astronomers can sign a petition in favour of moving the planned industrial project: docs.google.com/forms/d/e/1F...

Exciting news! We’re thrilled to announce that tapir Yuna gave birth to a rare and endangered Malayan tapir calf Sunday night. The newborn, covered in distinctive white spots and stripes resembling a fuzzy walking watermelon, is only the second tapir born in our 120-year history.

ESO has some fantastic images of comet C/2024 G3 from their observatory in Chile 🧪🔭 Credit for this one belongs to F. Millour/ESO

The most shocking part of this photo are the words that have not been painted over as yet. They aren't even all "DEI" words. And yet, they are being wiped away. A re-write of history's lessons, the removal of the things that build a functioning society, to please the Emperor.

Here is a highly recommended thread that summarizes what has happened in scientific landscape in the US since Trump's inauguration. It makes for dystopian reading ⬇️

As expected, the Trump team is already deleting climate info from government websites. In anticipation, our team at Urban Ocean Lab created a permanent archive of 100+ key resources and published a permanent archive: www.urbanoceanlab.org/resource-hub 👩🏽‍💻

I am looking to hire a PhD student at Swinburne University to study the links between pulsars, magnetars and fast radio bursts! If you or anyone you know may be interested, then please feel free to reach out to me via email. #Astronomy #RadioAstronomy astronomy.swin.edu.au/study/phdpro...

The Earth-based gravitational wave detectors (LIGO/VIRGO/KAGRA) looked for continuous GWs across 45 pulsars (which can be formed by tiny little mountains on their surface) but found no continuous GWs. Sadness. [note - these are not the GWs we search for in pulsar timing] arxiv.org/abs/2501.01495

Scientists, academics, researchers: We’re excited to share that @altmetric.com is now tracking mentions of your research on Bluesky! 🧪

Hot off the press paper co-lead by @pinkastrophysicist.bsky.social - mapping the gravitational wave background across the sky 🤩🔭🧪⚛️

What generates the gravitational waves that make up the background? It is probably supermassive black-hole binaries and/or early Universe physics. We don't know yet but it is likely a combination of both! 💥 It's paper release day tomorrow! Excited to share with you all!

My first first-author paper just dropped on arXiv ✨👩‍🔬🧪🔭 Introducing the KiloNova and Transients Program (KNTraP), a search specifically designed to find a kilonova. Check it out here to see the methods developed to scour the data for kilonova candidates, and what we found: arxiv.org/abs/2411.16136

What is the difference between gravitational-wave signals measured by LIGO and pulsar timing arrays? Well lots of things, but mainly the mass of the black holes. This infographic summarises the differences. 👀🕳️💫

I had a hard time finding women physicists here. So I made a starter pack for #female and #under-represended #minorities in #physics, in short #FURMIP. Please spread the word and let me know if you would like to be added. go.bsky.app/2JeYsDz

In honor of all the new arrivals, I'm sharing one of my favorite videos. It shows 24 hours of Earth's rotation, with the camera locked to the sky instead of the ground. We're all hanging out on this spinning rock. Brilliant work by Bartosz Wojczyński. 🧪 artuniverse.eu/gallery/1907...
