Euclid Flagship 2 Update

Posted in Euclid, The Universe and Stuff with tags , , , on September 22, 2025 by telescoper

I was thinking earlier today that it’s been a while since I last posted anything about the European Space Agency’s Euclid Mission but I’ve got an excuse to remedy that today because there is a brand new a press release about the Euclid Consortium’s Flagship 2 simulations, a (low-resolution) visual representation of one of which is shown above.

The news is that the largest ever synthetic galaxy catalogue is now public; a team of 8 institutions within the Euclid Consortium, led by the Institute of Space Sciences (ICE-CSIC) and the Port d’Informació Científica (PIC) in Barcelona have developed this `mock’ catalogue, which includes 3.4 billion galaxies, each with 400 modelled properties available for the scientific community. It was constructed to help analyse data from the Euclid mission, but has many other potential uses so is being shared otuside the Consortium.

You can read more about this catalogue, and also find out how the access the simulated catalogues, here. You could also read the scientific paper describing the flagship simulations here.

P.S. The first main data release from Euclid (known to its friends as DR1) will take please on October 21, 2026. That’s just 13 months away…

Euclid Updates

I’m travelling back to Barcelona today, later than planned because I’ve had a heavy cold that I struggled to shake off and didn’t want to infect fellow passengers on the flight. While I’m in transit I thought I’d share some updates about the European Space Agency’s Euclid mission.

The first thing to share is a piece by Knud Jahnke with news about Euclid’s issue with ice in the optical system. The latest intervention has led to an improvement, but since it is a closed system ice will probably form again – though perhaps not in the same place – and further procedures will probably be necessary in future. In the meantime, though, the survey resumes.

Now for some short videos -three, to be precise – about the Early Release Observations mentioned here. I posted another one in this series here. I think the titles are self-explanatory:

And if that isn’t enough, for those of you who like simulations here is another video about the Euclid Flagship simulation described in this paper.
