I mean it’s a few billion years in the future, but can’t help but think about the possibility of a collision between the Milky Way and Andromeda: spoilers - LMC gets engulfed but M33 stays intact!
Pulsars can measure the gravitational force directly! So the more we find, the better we can understand whether an intermediate mass black hole exists at the heart of Omega Centauri.
We learned a lot of things here. Apparently galaxies can be banana shaped and UV emission can be dominated by nebulae emission rather than star formation.
Check out our latest episode! At the end of a tiring week, definitely one of my favourite things is to curl up with the coolest research from the last few weeks!
The elusive BH seed! Could this be the answer?
Cool that you can do this at all.
Interesting paper about the mischief binary stars can cause for Galactic archaeology studies.
Dwarf galaxies aren't much good at retaining gas so it will be interesting to find out how big that central black holes can get!

Ancient stars and black holes - what more could you want!
It's definitely not perfect but hopefully a good start!
Went to a fun workshop today ran by @niftyfoxcreative.bsky.social about how to optimise using AI for creative tasks. We put together a design brief for creating an infographic for a research paper and I eventually got this. I like it! You can find out more at academic.oup.com/mnras/articl....
Episode 31 – Near Earth Objects, Little Red Dots, bursty star formation and life around massive stars
In this podcast episode, Michelle and Payel discuss theories on little red dot formation, bursty star formation, and the origins of asteroids like Apophis. They also discuss the potential for life…
Our latest episode is live! Tune in to hear about where the Apophis asteroid came from, bursty star formation at high redshift, truple-double radio galaxies and more! Available below and wherever you get your podcasts 🔭 ☄️
This is why we love doing Starxiv! Definitely one of the coolest objects that I had never heard about.
Can help but love such a simple model to explain the MUV-M* observations.
I was amazed that the Habitable Zone makes a comeback post Main Sequence.
Another exciting theory to explain Little Red Dots!
Let's hope those calculations are accurate!
I'm very excited to announce a PhD position that will be supervised by Eugene Vasiliev and myself on the dynamical modelling of barred galaxies. Check it out!
I like this theory too! It's like watching a very slow release Netflix series...
Paper time! @amerygration.bsky.social develops a general method for constructing the joint mass function of a stellar population that hosts binary stellar systems. And no it's not the same as the initial mass function!
I love that we're pushing back major epochs of galaxy evolution further back in time!
I couldn't helping thinking that we're possibly uncovering the merger history of GSE itself from its chemical abundances?
Chatted about this again over lunch with Surrey Astro! Very exciting paper.
Really interesting result here that the faint tidal tails tell us most about merger activity.
My favourite statistic from this week's podcast - JWST sees 100,000 galaxies in the area spanned by the moon!
JWST and machine-learning are definitely recurring favourites!
Recovery of total mass profile, dark matter mass profile, and flattening of the dark matter halo with 3D phase-space information.
Excited about the latest paper with collaborators! We find that in the case of missing phase-space coordinates, equilibrium dynamical models can recover the mass distribution and inclination of disc galaxies well but not the dark matter halo flattening! Find out more at arxiv.org/abs/2511.10445.
