Made it to the centre of our Milky Way... The Galactic centre has a high density of stars and stellar activity: stars forming, stars dying, stars orbiting our supermassive black hole. Hence it's a great place to search for exotic radio transients. More #RadioAstronomy results coming soon!

Just wrapped up a typical 1-hour VLBI collaboration meeting. We talked 60 min organization and methodology, and 0 min science. The VLBI community has a huge efficacy issue. We need to get *much* better. #RadioAstronomy πŸ”­β˜„οΈπŸ§ͺ

This object may help bridge the gap between regular pulsars (that usually rotate much faster) and long period transients, and emerging class of objects which rotate extremely slowly. Here is a plot of the pulses observed with the MeerKAT telescope. #RadioAstronomy #AstroSci
A plot of flux density versus time for a very slowly rotating pulsar. The data is from the MeerKAT telescope. The low band observations are shown in orange, and show very clearly the pulses every 41 seconds. Image credit: Yuanming Wang.

I have been using ATNF facilities for my entire career. Here's a picture of my favourite one - the Australia Telescope Compact Array. I did my first #RadioAstronomy observing here, and my entire team still uses it for following up radio transients.

Slow variable pointwise radio source from my collections on Zooniverse Coordinates: 282.206987053898 , -1.49966214209343 Data Credits: Project "Bursts from Space: MeerKAT" Click radio image and "light curve" for more #astronomy #radioastronomy #timedomainastronomy #citizenscience #zooniverse
Bursts from Space: MeerKAT https://www.zooniverse.org/projects/alex-andersson/bursts-from-space-meerkat Subject Number: 70786879 Talk on the subject: https://www.zooniverse.org/projects/alex-andersson/bursts-from-space-meerkat/talk/subjects/70786879 The flux density from this astronomical object was expressed in milliJansky unit, by a color map (not real colors). The orange blob at the left bottom is the PSF ("point spread function"), showing the shape of an ideal pointwise source as recorded by the radiotelescope taking in count the spatial resolution of the instrument, and the sky position of the object. Reference with my contribute as a citizen scientist: https://doi.org/10.1093/mnras/stad1298
Almost all of the error bars are smaller than the diameter of the dots, still showing a significative dynamic range in the flux density over the time. The variability amplitude is about 40 mJy, excluding the outliers. The median flux is about 15.7 mJy. The subject has a good activity in the explored time window, for the available time resolution, with a first distinctive growing phase between the epochs 59300 MJD - 59350 MJD; a falling phase between the epochs 59350 MJD - 59425 MJD; a second prominent growing phase between the epochs 59425 MJD - 59525 MJD. "MJD" stands for "Modified Julian Day": this is a time unit used by astronomers to refer to an event "zero", without having to calculate the days from the ordinary calendary. This is a uniform time reference.

Just catching up on this excellent #RadioAstronomy work by ProAm group using the Dwingeloo Telescope. πŸ”­πŸ“‘ They managed to fire a signal at Venus, and catch the reflection back on two antennas here on Earth! There is *lots* of nice working coming from this group! πŸ‘πŸ‘πŸ‘ Blog + link to script below

We used the historic Dwingeloo telescope to bounce a signal off the surface of Venus, and receive its echo! This marks only the second time that amateurs have achieved an 'EVE' (Earth-Venus-Earth) bounce. Venus was about 40 million kilometers from Earth. www.camras.nl/en/blog/2025...

Graphs showing EVE detections: 5.4 sigma for Dwingeloo-Dwingeloo, 8.5 sigma for Dwingeloo-Stockert, 9.2 sigma for combined Dwingeloo/Stockert

oh wow! Congrats! πŸ‘πŸ‘πŸ‘ CHIME is an FRB beast, and localization is a game changer! #RadioAstronomy β˜„οΈ

The dawn of a new era: the very first sub-arcsecond localization of a fast radio burst using the CHIME telescope and its outriggers. 
 Congratulations to the amazing group of students and postdocs who have led this incredible achievement over the past frenetic 11 days!

WOW 30 MILLIarcsecond resolution is like... a Millionth of the width of your finger viewed at arms length, for reference (give or take a factor of 10) πŸ§ͺπŸ”­ #RadioAstronomy πŸ“‘ LOL fixed thanks @philplait.bsky.social Should have finished my coffee first...

Super proud of my PhD student Osmar who discovered that the so-called 'compact disks' around young stars are REALLY REALLY small! Look at the full sample of Lupus disks, observed at 30 mas resolution with ALMA.
