Euclid2018: Highlights of Day 2

I’ve just had my breakfast so I thought I’d do a quick post before the start of play at Day 3 of the 2018 Euclid Consortium Meeting in Bonn.

Day 2 was largely devoted to updates from the various Science Working Groups, but there was also an important presentation from Jason Rhodes about WFIRST, which is in some ways a rival to Euclid, or perhaps a complementary mission depending on how you look at it.


There was dismay in the global astronomy community last year when Donald Trump proposed taking the axe to WFIRST but it was good to hear that Congress not only reversed his decision but granted it additional funds over and above the original request.

Among the SWG updates was one by Alessandra Silvestri from the Theory Working Group concentrating on how Euclid could be used to test cosmology beyond the standard model. She focussed quite a lot on Horndeski Gravity, which is the most general four-dimensional scalar-tensor theory that leads to equations of motion that have the form of second-order differential equations.

Towards the end of the day there was a session devoted to the award of the Euclid Star Prizes.

The individual awards went to Micaela Bagley, Carmelita Carbone, Teake Nutma, Bertrand Morin, and Stefanie Wachter; more details on the winners and the awards they won will be posted here. The team award was given to the Flagship simulation team. Coincidentally, I posted about the Flagship simulations last year. Much of the preparation for Euclid would be impossible without these simulations, and the award of a prize to the team is very well justified.

The day finished with short talks from each of the prizewinners. That brought to the end two days of plenary sessions in the big hall of the Stadthalle. The next two days will be the `Splinter sessions’ which are held in parallel.

Oh, and one other thing: the 2019 Euclid Consortium Meeting will be held in Helsinki from June 4-7. Looks like I’ll be spending my birthday in Finland next year!

P.S. Previous Euclid Consortium meetings were: Bologna (2011);  Copenhagen (2012); Leiden (2013); Marseille (2014);  Lausanne (2015); Lisbon (2016); and London (2017).
