The @OpenUniversity has a nice news article on the
@ec_euclid data release today, including some breakthrough work on gravitational lens discovery done by my grad student Ruby Pearce-Casey #astrodon https://www.open.ac.uk/blogs/news/science-mct/euclid-mission-reveals-spectacular-new-space-discoveries/

A nice write-up by @TheGuardian on the @ec_euclid data release, including some quotes on the avalanche of gravitational lenses by @stephenserjeant #astrodon https://www.theguardian.com/science/2025/mar/19/scientists-hail-avalanche-discoveries-euclid-space-telescope

Big data release day! The first
@ec-euclid.bsky.social
data release is out now: https://www.esa.int/Science_Exploration/Space_Science/Euclid/Euclid_opens_data_treasure_trove_offers_glimpse_of_deep_fields And this is just the very start of Euclid's discovery adventure #astrodon

Very happy to have been part of the @ec_euclid discovery of a jaw-droppingly beautiful gravitational lens in our cosmic back yard. Here's an explainer video (with subtitles for accessibility) that I made for the @OpenUniversity and I'll post a few more links in this thread #astrodon

Beautiful gravitational lens in our cosmic doorstep discovered by the @ec_euclid consortium. In the future, Euclid's spectroscopy will give us new windows into these warps in space and time.

Our ELSA meeting conference, after a few days playing with Euclid @ec_euclid spectroscopy. We're enjoying the cognitive dissonance of being in a 18th century building working on a 21st century space telescope #astrodon

We can't wait to see everyone at #AAS245!

Next week is the 245th meeting of the American Astronomical Society — the largest gathering of astronomers in the US. We're gearing up for some exciting talks and sessions that'll preview the incredible science coming later this year once Rubin comes online!

At #AAS245 you will find the special session "241 - The Euclid Mission: First Results and Opportunities for Archival Research" on Tuesday, January 14, 2:00-3:30 PM, in National Harbor 10.

Five presentations on the current state of Euclid and it's upcoming first science data release.

Our annual ELSA meeting has kicked off! Beautiful location in Bristol University’s Goldney House, which looks like it’s straight out of Downtown Abbey @ec_euclid

Happy holidays from @ec_euclid and the Euclid ELSA project

A common theme of many of the excellent talks at the @ec_euclid UK meeting today at the beautiful @royalastrosoc has been application of machine learning technologies: cGANs, Bayesian CNNs etc. Also many examples where human input via citizen science is crucial to the ML workflows for truth sets #astrodon (Pics courtesy of Euclid UK)

@mathisnoiz @esa_euclid @ec_euclid @the_zooniverse Wonderful!

New artwork inspired by the quest to discover new gravitational lenses in space by using Euclid telescope's data, machine learning, and the hivemind of a thousand volunteers.

Fun fact this was mainly created by using non-euclidean fractal geometry!

Congratulations to @ec_euclid member Ruby Pearce-Casey - her excellent paper on finding strong gravitational lenses with #MachineLearning has been picked up by a #YouTube channel with nearly half a million subscribers 😀 #astrodon https://www.youtube.com/watch?v=XZKzZF-0w3c

Would you like to spot warps in space and time? The @ec_euclid #Euclid space telescope consortium needs your help! With this help from you, ELSA will unpick what's going on in newly-discovered magnified background galaxies with Euclid's spectroscopy. To have a go, visit https://www.zooniverse.org/projects/aprajita/space-warps-esa-euclid . To see more about why we're doing this, see this thread by @stephenserjeant https://mas.to/@stephenserjeant/113554729272229262 #astrodon

A corollary is that our avalanche of ~100000 gravitational lenses from #Euclid @ec_euclid currently needs people to eyeball a million candidates! This is why citizen science is crucial to making a success of one of the Euclid space telescope's major legacy science areas #astrodon https://www.zooniverse.org/projects/aprajita/space-warps-esa-euclid

Very happy to see my grad student Ruby Pearce-Casey's first fully refereed paper at number 1 on the arXiv mailing this morning - and it's a beautiful piece of work in the #Euclid @ec_euclid consortium, a big step forward in machine learning/AI methods to find strong gravitational lenses #astrodon https://arxiv.org/abs/2411.16808

We're delighted to announce a new citizen science project: SPACE WARPS - ESA EUCLID. Browse the @ec_euclid data and be the first to discover warps in space and time! https://www.zooniverse.org/projects/aprajita/space-warps-esa-euclid #astrodon

Dida Markovic from the @ec_euclid #ESA #Euclid consortium is on the Why AxS podcast, talking to the internationally renowned artist Lita Albuquerque about dark matter. Enjoy! #astrodon https://www.artcenter.edu/connect/dot-magazine/articles/dark-matter-tiny-humans-vast-universe.html
