Je connaissais Karim depuis que je l'avais eu comme prof en M2 en 2007. C'était une figure de la cosmologie en France que je recroisais régulièrement. C'est tellement soudain et aléatoire.
Mes pensées vont à ses proches dans cette terrible épreuve.

La communauté @iap.fr a l'immense tristesse de vous annoncer la disparition brutale de Karim Benabed, dans un accident de la circulation, hier après-midi, le 3 décembre.

And is "pedagogy" is the new excuse for bold unfounded claims after "we need to catch the interest of the public"?

3 problems here:
- you assume that a person who was a very productive researcher on one field can be relevant in another
- you assume that "brillant" people remains "brillant", but people sometimes lose their skills/sanity for various reasons
- you assume citation metric correlates with quality

I was searching for the cat. There was a strange bump on the guest bed. I looked under and clearly disturbed someone's nap.

Q1 Day – Euclid’s First ‘Quick’ Data Release
Today is Q1 Day! This means the first public release of data from the full Euclid Survey. It's only a very small portion (0.4%) of the survey - just 63 square degrees on the sky, while the full survey will be over 14,000 square degrees - but in contrast…

It's only a very small portion (0.4%) of the survey - just 63 square degrees on the sky, while the full survey will be over 14,000 square degrees - but in contrast to earlier data releases, this has been passed through the full Euclid Ground Segment so it represents the true quality of the data we can expect for the rest of the mission.

Thanks for co-organizing this workshop. Lots of interesting discussion, a very collaborative spirit, and lots of scientific puzzles to solve together. Science should always be like this!
We spent a great week at Lorentz Center in Leiden talking about the Synergistic views of ALMA and JWST of the early Universe, and planning how to move forward our understanding of the first galaxies!

A businessman is seated next to a scientist. Another businessman comes claiming it is its seat. While the scientist checks the ticket again, the seated business makes a remark about people seated at the wrong spot... before realizing he was on the wrong spot. 2 jobs with different cultures of doubt.

And thanks again to the ALMA observatory for the beautiful data. These are only partially observed programs (~20%). Imagine what we could do at full depth! I really hope that we will ultimately be lucky and that one day the 500pc observations of VC875 will be completed...
