1. First Einstein Telescope workshop (February 4, 2021, remote)
it is a pleasure to announce the first ET-France workshop, on February 4, 2021, by videoconference. 

The purpose of the workshop is to have an exchange of information on the project and to discuss the participation and organization of the french community.

The workshop is structured in 4 sessions: 

  • general information session, 
  • the science with ET, 
  • the instrument and the R&D,
  • discussion session. 

The indico website will be updated in the coming weeks with detailed information about the presentations. But you can already register.

2. School of Statistics 2021 (18-29 January 2021, online)

We are pleased to announce the opening of the registration for the School of Statistics SOS 2021.

The pandemic prevented us from holding the school as originally planned in May 2020. It will instead happen, fully online, on 18-29 January 2021, half-a-day each day.

The school targets PHD students, post-docs and senior scientists wishing to strengthen their knowledge or discover new methods in statistical analysis. Lectures will be given in English and span from fundamental concepts to advanced topics. A special focus will be put on machine learning techniques and tools and a significant amount of time will be dedicated to hands-on sessions.

Registration is accessible here: https://indico.in2p3.fr/e/SOS2021
as well as the list of lectures and lecturers. The detailed program is still being worked on and will be added soon. The school will be spread over two weeks to avoid zoom fatigue from five straight days of videoconferencing.

4. Postdoctoral Opportunities to work on galaxy clusters at Ludwig-Maximilians-Universität (Munich, Germany)

Application deadline: January 22, 2021. 

Two openings for postdoctoral positions to work on galaxy cluster related science:

The Physical Cosmology group at the University Observatory of the Department of Physics at the Ludwig-Maximilians-Universität München and the Excellence Cluster ORIGINS announce the opportunity for two Postdoctoral positions in the area of cosmology. Scientists with a PhD degree in Physics, Astrophysics or related fields are invited to apply. Successful applicants will be expected to conduct original research in the field of galaxy clusters in an active interdisciplinary environment. The post holders are expected to work 50% of their time, in the first two years of this position, towards software infrastructure contributions to the Rubin Observatory Legacy Survey of Space and Time (LSST) Dark Energy Science Collaboration (DESC) galaxy clusters working group.
We aim to fill the both positions from as early as September 2021 but the latest until December 2021. The position is part of the research group under the lead of Professor Jochen Weller. For the Postdoctoral position we are looking for a person with a background in software development in either theoretical, phenomenological or observational cosmology including the areas of dark energy, large-scale structure, clusters of galaxies, cosmic microwave background or machine learning in astrophysics. Possible experience in collaborative software development would be beneficial. In addition to the work towards DESC, the research assistants can play an active role in at least one of the following surveys: Euclid, Dark Energy Survey (DES), eRosita and possibly SKA.
The salary is paid according to the German public service pay agreement TV-L E13. The advancement of women in science is an integral part of the university‘s policy. Therefore, women are especially encouraged to apply. Persons with disabilities will be given preference to other applicants with equal qualifications.
