From Avignon to Heidelberg

The last few weeks have been really hectic with trips down south to Avignon where I was one of the organisers of the fourth PONT Avignon conference. This is a conference about cosmology and astroparticles which we organise every three years. Apart from the terribly cold weather and a foggy trip to Mont Ventoux, the conference was a success with many excellent talks. We are already thinking about the fifth conference although time is already clicking too fast so I would rather not think about three years ahead. On the way back, I went to the Euclid Theory meeting in Heidelberg where again there were very good presentations of the future Euclid mission, one of the main experiments looking for dark energy and modified gravity signals, which is to be launched soon. An occasion also to see old friends as most of the people involved in this type of research in Europe were there. And then again as soon as back in Saclay, we had the general public meeting on gravity that I organised with Etienne Klein and Pierre Vanhove. A great success I believe with scientists, historians and philosophers talking about cosmology and general relativity.

Time to got back to work now with proper calculations to finish, articles to publish and a bit of rest before a mad month of June. More stochastic calculations, bimetric models and decoupling limits to take.
