Exciting new observations shedding light on what drives the shape of solar flare ribbons.

A non-linear data compression that preserves orthogonality - one of the key pluses of the linear PCA.

000

This was a very cool paper where JWST literally sees the missing link between large-scale gas flows and gas accretion onto the central black hole of a galaxy.

000

Nicole told us how simple linear tools can help us to more simply interpret galaxy spectra. I love the everlasting power of PCA!

Here’s our press release about Arrakihs! Lots of cool science will hopefully come out of it and I’m especially excited about what can be done with the long streams it will detect. 🔭☄️🧪 www.surrey.ac.uk/news/esa-off...

I really enjoyed this paper! Who knew that the craters that formed early on eject material that can reform craters later and cause an asymmetry in crater distribution across the Moon's surface.

Fun as ever chatting about papers with Michelle. We happened to say lots of odd things this time too. Like claiming that one of the papers was published in A&E. We'll be saving bloopers for a special episode soon!

Michelle discussed a very cool possible candidate for a primordial black hole. Tune into this week's @starxiv.bsky.social podcast to find out more!

Another great use of machine learning for classification in astronomy.

It's kind of cool that we're starting to get detailed age and metallicity profiles for galaxies at redshift 1!

000

GSE possibly happened further back in time than we initially thought!

000

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?

000

Cool that you can do this at all.

000

Interesting paper about the mischief binary stars can cause for Galactic archaeology studies.

000

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!

The StarXiv ✨ podcast @starxiv.bsky.social · 02/03/2026

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 around massive stars and unusual triple-double radio galaxies.

This is why we love doing Starxiv! Definitely one of the coolest objects that I had never heard about.

000

Can help but love such a simple model to explain the MUV-M* observations.

000

I was amazed that the Habitable Zone makes a comeback post Main Sequence.

Chris Lintott @chrislintott.bsky.social · 03/03/2026

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!

Payel Das @payeldas.bsky.social · 19/02/2026

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?

000

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.

000

My favourite statistic from this week's podcast - JWST sees 100,000 galaxies in the area spanned by the moon!

000

Payel Das @payeldas.bsky.social · 14/11/2025

JWST and machine-learning are definitely recurring favourites!

000

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.
