@NatureAstronomy @ESA_Webb The research was led by @MU_Physics Daxal Mehta and supported by research group leader Dr John Regan and research team member Dr Lewis Prole.

This work shows the importance of light seeds in cosmological simulations. Going forward the contribution of light seeds will need to be included in larger scale cosmological simulations in order to holistically account for the full black hole seed population. @Researchirel

My PhD student Daxal Mehta had a paper published in @NatureAstronomy this morning. Using state-of-the-art cosmological simulations we found that light seed black holes can grow extremely efficiently in very early galaxies-potentially filling the gap between light and heavy seeds.

On @newstalkscience this afternoon (~ 12.30) talking about primordial black holes and what they might mean for dark matter and black holes in the early universe. Tune in! @MaynoothUni @MU_Physics @Researchirel @royalsociety

The second meeting of the National Advisory Forum for Space Research took place this week at Maynooth University, during Irish Astronomy Week! The Forum brings together a broad range of stakeholders and expertise to discuss what’s next for Space R&I in Ireland.

Brilliant night in @MaynoothUni for @SpaceWeekIRL event last night. Packed lectures from exoplanets to cosmology. Thanks to @BlackRockObserv for bringing astronaut Steve Swanson along! @MU_Physics @MU_Research

@MichaelTremmel @maximetrebitsch I took that Ferry a few weeks ago from Roscoff. It was great. Highly recommend it.

@maximetrebitsch I can refer you to my colleague that does that with family each year at Xmas time to go home to Germany!

Just got the email that it’s time to submit proposals for sessions at EAS 2025 in Cork! We can’t wait to welcome many of you into the best city in Ireland (and of course the true capital). Im sure it’ll a great meeting and lots of interesting sessions! mail.eventsairmail.com/ls/click?upn=u…

A little over a week to go to our 5k Summer Road Race ⏳⏳⏳ Great course for a PB ✅ Great individual prize money for multiple age categories ✅ Mega Team Prize 👀🔥 Great after race cakes 😋 popupraces.ie/race/celbridge… @popupraces @KildareAthletix

What a superb run by our women’s 4x400m relay team to finish 4th in the @Olympics final with a huge national record of 3:19.90! 🇮🇪☘️ So grateful to these wonderful athletes: @sharlenem229 @rhasidatadeleke @sophiebecker_ Phil Healy ⁦@TeamIreland⁩ #Paris2024 #Olympics

What an amazing run by the 4x400m women's relay team for @irishathletics. I've never seen an Irish team perform at that level before. They did us proud!

@Darrenfrehill Absolutely amazing. They were unreal.

What a run!!!!!!! 👏👏👏👏

That's not good. We really need to stand up and boost spending on research. A resilient and well supported research model is so important for third level education and everything that depends on it.

Join us for the best 5k road race of the summer on Thursday 22nd August 👌🏻 Great prize money, mega team prize of €1,000 for first team home (2 male/female), course record bonus (14.27 & 15.59), great after race goodies 😋 @popupraces @KildareAthletix popupraces.ie/race/celbridge…

The Big Reveal, this Thursday: esa.int/Science_Explor…

Last week we welcomed about 80 astrophysicists from around the world to Kinsale to discuss the evolution of massive black holes in the first billion years of the Universe. I think it was a success! Tons of interesting presentations and discussions #BlackHolesKinsale

@Fabio_Pacucci @MichaelTremmel Thanks Fabio!

It's a wrap for the conference #BlackHolesKinsale! In the final panel, we summed up the current state of black hole astrophysics with this meme. Many lingering questions mean exciting discoveries ahead! :) Thanks @jaregan and @MichaelTremmel for an amazing conference!

I'm excited to be at #BlackHolesKinsale presenting my paper on contextualizing high-z quasar host detections in simulations (thanks to @ARC_ASTRO3D)! I never thought I'd be going to a small, idyllic town in Ireland to present work from the first part of my PhD 😍

Great group down here in Kinsale for our "Massive Black Holes in the First Billion Years" conference. Another exciting day of talks in store for us today. #BlackHolesKinsale

Postdoc Position @MU_Physics to work on JWST observations of SN1987A with @paddyk_astro aas.org/jobregister/ad… Please share!
