Yale Frontier Fields Workshop

Hubble and Spitzer have observed galaxies over 95% of the way back to the Big Bang, well into the epoch of reionization and close to the dawn of galaxy formation. The most distant galaxy candidates have been discovered using two complementary observational strategies: blank field observations such as CANDELS and the Ultra Deep Field; and galaxy cluster lensing programs such as CLASH. Additional deep observations are required to discover larger samples of distant galaxies and mitigate the cosmic variance of the single UDF. Deep lensing observations can reveal even fainter sources that would otherwise be inaccessible to current telescopes. Continua a leggere Yale Frontier Fields Workshop

GES 2014: Gaia-Eso Survey Second Science Meeting

The Gaia-ESO Survey (GES) is currently half way to achieve its goal to collect spectra for 100 000 stars over a period of five years. The survey is providing an homogeneous overview of the distributions of kinematics and elemental abundances for the major components of the Milky Way, namely the bulge, the thick and the thin discs and the halo. In addition to the field component, a very significant sample of open star clusters, covering all accessible cluster ages and stellar masses, as well as a handful of globular clusters are being observed.

Rencontres de Moriond on Cosmology

The Rencontres de Moriond session on Cosmology will review the subject 2 years after the last edition.

The main topics of the conference are:

  • CMB anisotropies
  • Reionization
  • Dark energy probes
  • Dark Matter
  • Inflation
  • Modified gravity
  • Massive gravity
  • Galaxy clusters
  • SZ
  • Non gaussianities

The conference will include both review and contributed talks and will be organized only in plenary sessions

Alpine Cosmology Workshop 2013

This is an annual workshop organized since 2009 by scientists of University of HelsinkiMax-Planck Institute for extraterrestrial Physics (MPE) and The University of Innsbruck.

The concept of the workshop is to combine a scientific part, in which each participant delivers a review on their topic with a group activity in which every participant is engaged. To this end we have selected to conduct the workshop at several huts located in the Alps, connected by hiking trails. Each day has approximately 6 hours of the workshop and 6 hours of hiking, during which the participants usually continue the discussion of the scientific topics and establish new collaborations. The no escape principle, and no contact to outside, possible during the workshop, are unique attributes of the conference and allow participants to concentrate entirely on the subject of the conference, which includes:

  • Cosmology and surveys
  • Physics of galaxy clusters
  • Coevolution of galaxies and black holes
