@railair Is there any information on the 11:10am bus from Guildford to Heathrow Terminal 2? This bus hasn’t arrived yet.

[Dr Joanna Sakowska @joannasakowska]

I’ve done it! I’m now a doctor of astrophysics! 🥳🎉🎈

We have a little tradition of a PhD viva hat- mine has an axolotl eating the SMC, with the LMC on the other end 😂

This is our current "greatest hits" collection of stellar tidal streams from our poster in the meeting "The Milky Way Assembly Tale" celebrated in Bologna this week, selected from our current sample of more than 100 streams (and increasing) from our "Stellar Stream Legacy Survey"

Congratulations to Jason Hunt who won an ERF to work on disequilibrium in the Milky Way at Surrey!

[University of Surrey @UniOfSurrey]

What's making the Milky Way ripple? Surrey scientists are set to study those ripples to discover the origins of our galaxy.

Here's how the Milky Way's gravity pulled apart the Messier-10 cluster of stars over 2 billion years.

Surrey scientists correctly predicted it - now, new data from the @esa_euclid telescope confirms it!

It's great to see the first tranche of Euclid results coming out. Here's a highlight of our contribution on 2 Milky Way globular clusters led by Davide Massari - https://t.co/UL9bQHFKlA

[Denis Erkal @deniserkal]

We can detect the tidal distortion in the outskirts of the cluster thanks to Euclid’s depth and wide field of view

[Denis Erkal @deniserkal]

For the Euclid release, I made a fun movie of the globular cluster M10 (NGC 6254) showing its tidal disruption in the Milky Way. The frames are every 100000 years so it’s fun to watch the stars in the outskirts of the cluster. https://t.co/SGCH6kRraQ

@astro_pwise @STFC_Matters @unisouthampton @AstroPhysSoton @LSSTUK Congratulations!

@Cosmic_Horizons I’ll take that friendly little guy over a funnel web any day!

[Denis Erkal @deniserkal]

@borja_anguiano @AgEInves @CienciaGob I am well and glad to hear you are too!

[Denis Erkal @deniserkal]

@AJamesMcCarthy Even more awesome! 30 hours does sound pretty deep.

Check out Madison’s paper on how we can use streams to measure the dark matter haloes external galaxies

[Madison W. @madastro_]

It's paper day!!✨ Very happy to announce that my first paper is (finally) on the arXiv today! Check it out if you want to find out how we can use stellar streams living in the outskirts of galaxies to learn about their dark matter halos! 🔭 https://t.co/l9AkZJNI2G
