We have found observational evidence that dark matter is “heated up” at the centres of dwarf galaxies: arxiv.org/abs/1808.06634… This solves the long-standing “cusp-core” problem in LCDM, and suggests that dark matter is a cold, collisionless, fluid. [A thread]

Paper day! @IzzyGrayAstro proposes a new model for NSC formation in tiny dwarfs. Prediction: NSCs should have CMDs with >2, distinct, MS turnoffs. Some nearby CGs like OCen and M54 show exactly this behaviour, suggesting they could be accreted NSCs! arxiv.org/abs/2405.19286

I am happy to announce my first paper is on the arXiv today! We present a new model for nuclear star cluster formation within dwarf galaxies using high-resolution cosmological simulations, including observational properties and links to globular clusters: arxiv.org/abs/2405.19286

Come and hear Physics PGR Astha Astha and Astro Prof @ReadDark talk about dwarf galaxies and dark matter in the "To Infinity and Beyond" event on 14 May: pintofscience.co.uk/event/to-infin…

Are you an astronomer or aspiring astronomer wanting to improve your software engineering skills? Applications for Code/Astro 2024 are open! More info at semaphorep.github.io/codeastro/. Application is linked at the bottom of that page. Apply by Feb 16! (Copied from Sarah Blunt :))

@TorstenAkesson @rtorkar New results like this are super-exciting because we don't yet know how supermassive black holes form. However, the black hole mass in this case is not well constrained so competing theories can all work, for now.

@rtorkar I am not an expert so please take my answer with a grain of salt. But, @ReadDark is an expert and maybe has time to give a more solid answer (and correct mine).

400 million yrs is a bit early, no @TorstenAkesson? nature.com/articles/s4158…

Interested in more than one position? No problem, apply for one and indicate that you would like to be considered for other positions in your covering letter. Come and join @surreyastro !

or study supermassive black holes and gravitational waves with @astroalessia?jobs.surrey.ac.uk/Vacancy.aspx?i…

or on globular clusters with @ReadDark ? jobs.surrey.ac.uk/Vacancy.aspx?i…

Fancy working on dwarf galaxies with @michelle_lmc? jobs.surrey.ac.uk/Vacancy.aspx?i…

Would you like to join the fantastic astrophysics group at Surrey? We have 3 STFC funded postdoctoral positions in the areas of gravitational waves, dwarf galaxies and globular clusters @surreyastro

jobs.npl.co.uk/vacancies/1915… Permanent job (Higher Scientist) .@NPL in gamma-ray spec...please pass on and please contact me if interested :)

@astro_francesca Congratulations! Awesome news!!

Still can't quite wrap my head around this!🤩 So excited that I get to research galactic dynamics & the nature of dark matter, build up my group at Durham, and bring science closer to girls from post-conflict regions! ✨ #WomenInSTEM

I'm hiring a postdoc in my group (@MITKavli @MIT_Physics ), working on a combination of machine learning, Dark Matter, Gaia, and simulations. The due date is FRIDAY! Please forward to interested candidates! academicjobsonline.org/ajo/jobs/25332

Last week I got to visit @DarkerMatters to give a FLAT talk, on my work with EDGE simulations and how we naturally form globular clusters within them! Everyone was so very welcoming! Thank you all for everything and I hope to see you all again soon!

Happy Halloween🎃As we celebrate the spooky season, we'd like to share a little treat with you... a glimpse into mysterious research of a Daphne Jackson Fellow. 🔬🌌Dr Susan Hutton is a Fellow at the @UniOfSurrey, sponsored by @STFC_Matters & is searching for answers...

On my way to @OxUniMaths to deliver the Roger Penrose Lecture. I feel very honoured to be invited to give only third one in the series - after Stephen Hawking (2017) and @carlorovelli (2020). I believe it will be available online in three weeks time.

I had a fantastic time today at the Surrey Future Fellows Festival! Amazing to see so much fascinating interdisciplinary work taking place across the university, and to hear about the exciting plans for @ReadDark's ECR academy 👏👏

We are so excited that the Stargazing nights at @UniOfSurrey are resuming! The first event will be on Wednesday 25 October at 7pm, featuring a public lecture by @ReadDark titled “How to heat up Dark Matter”, and a public stargazing session at the Surrey Telescope ✨🔭
