Swiss Cosmology Days 2015

Date: 5-6 February 2015

Registration deadline: 14 November 2014


The Swiss Cosmology Days are yearly meetings aimed at promoting communication and exchanges amongst Cosmologists working in Switzerland. They offer a national platform for scientists to present their research, lead exciting discussions and enable closer collaborations and networking. Young scientists are particularly encouraged to participate. The first meeting took place in February 2013 at the University of Bern and we were happy to count over 40 participants. The meetings are jointly organized by Professors Ruth Durrer, University of Geneva and Alexandre Refregier, ETH Zurich. 


Swiss Cosmology Days 2014 - ETHZ


The last Swiss Cosmology Days (counting over 60 participants) took place on 6 - 7 February 2014 at ETH Zurich, Switzerland and we are now pleased to announce the dates for the upcoming 2015 meeting: 5 - 6 February 2015 at the University of Geneva.


The meetings are open to all researchers in Cosmology working in Swiss Institutions. For further information regarding the upcoming Swiss Cosmology Days please view the following pages:

Please take note that the deadline for registration and abstract submission for the 2015 meeting closed on 14 November 2014. If you would like to register after this date, please contact us by email.




The next Swiss Cosmology Days are scheduled to take place on 5 - 6 February 2015 at the University of GenevaThe talks will take place in the Stueckelberg Auditorium. When entering from the main entrance of Ecole de Physique building, the room is located just at your right.

How to find us
Our location on Google maps

From the airport
Take a free ticket for the public transport system before you leave the luggage hall and go through customs. Then take a train to Geneva main station (all trains from the airport stop there next). Alternatively take bus number 10 to "Bel-Air" where you can either change to trame 14 to "Jonction" direction "P+R Bernex" or change to bus 19 to "Musée d'ethnographie" direction "Onex-Cité".

From the train station
Go to the front of the station and take bus number 1 to "Ecole-Medecine" direction "Rive". Alternatively, take tram 14 to "Jonction" direction "P+R Bernex" under the train tracks. This webpage of the theoretical physics department shows the location of the bus and tram stops when you come from the station.
