Euclid Updates

Posted in The Universe and Stuff with tags , , , , on June 17, 2019 by telescoper

Following the Euclid Consortium Meeting in Helsinki a couple of weeks ago, here are a couple of updates.

First, here is the conference photograph so you can play Spot The Telescoper:

(The picture was taken from the roof of the Finlandia Hall, by the way, which accounts for the strange viewpoint.

The other update is that the European Space Agency has released a Press Release releasing information about the location on the sky of the planned Euclid Deep Fields. Here they are (marked in yellow):

These deep fields amount to only about 40 square degrees, a small fraction of the total sky coverage of Euclid (~15,000 square degrees), but the Euclid telescope will point at them multiple times in order to detect very faint distant galaxies at enormous look-back times to study galaxy evolution. It is expected that these fields will produce several hundred thousand galaxy images per square degree…

Selecting these fields was a difficult task because one has to avoid bright sources in both optical and infrared (such as stars and zodiacal emission) so as not to mess with Euclid’s very sensitive camera. Roberto Scaramella gave a talk at the Helsinki Meeting showing how hard it is to find fields that satisfy all the constraints. The problem is that there are just too many stars and other bits of rubbish in the sky getting in the way of the interesting stuff!

Notes from Euclid 2019

I’ve just had my breakfast so I thought I’d do a quick post before the start of play on of the 2019 Euclid Consortium Meeting in Helsinki. Previous Euclid Consortium meetings were held in: Bologna (2011); Copenhagen (2012); Leiden (2013); Marseille (2014); Lausanne (2015); Lisbon (2016); London (2017); and Bonn (2018). I’ve only attended the last two: I was non-Euclidean before that.

Finlandia Hall

The venue is the Finlandia Hall, which looks splendid from the outside. I passed it during my stroll yesterday afternoon just so I could be sure where it is. It’s easy to find as it is very central and on the edge of a lake next to a major thoroughfare (Mannerheimintie). . I arrived yesterday to beautiful sunny weather but that has changed – it is pouring down as I write this, with thunder and lightning to boot. I don’t have to leave the Hotel for an hour or so, however, so perhaps it will have passed. There’s no sign of that just yet but I brought a brolly, and it’s only 15 minutes away from the Hotel on foot.

According to the web page there are 408 participants at the last count. I expect there’ll be quite a few people I know here but I haven’t met any yet. The Euclid Consortium has well over a thousand members, but obviously they’re not all here this week. I seem still to be the only representative of Ireland.

There’s a nice webpage showing all the institutions around the world who belong to the consortium behind the European Space Agency’s Euclid Mission. Here’s a screen grab that shows all the logos of all the institutions involved in this very large Consortium:

There are so many that it’s hard to see them all, but if you look very closely about half way down, among the Ms, you will see Maynooth University among them. Ireland is a member state of the European Space Agency, by the way.

Top tips for participants include not to tip:

Here is the latest timeline for the Euclid mission: launch around June 2022 followed by six years of operations.
