Most of the Darklight team will gather next week (4-8 July) in Sesto at the Sexten Center for Astrophysics, together with 30 experts, to discuss the analysis of the large scale structure of the Universe. The workshop will be focused in particular on Redshift-Space Distortions (RSD) and Baryonic Acoustic Oscillations (BAO) in the clustering of galaxies, two techniques that have…
Darklight @ Fondazione Faraggiana
Prof. Guzzo has been invited to deliver a talk on the expansion of the universe in Novara on Tuesday April 26, 2016 at 6pm. His presentation will be the third of a cycle of conferences open to the public entitled “Discovering our Universe” organized by Fondazione Faraggiana.

Group-galaxy correlations in redshift space as a probe of the growth of structure
Darklight PhD fellow Faizan Mohammad and co-authors investigate in this paper (MNRAS, Vol. 458, May 2016) the use of the cross-correlation between galaxies and galaxy groups to measure redshift-space distortions (RSD) and thus probe the growth rate of cosmological structure. This is compared to the classical approach based on using galaxy auto-correlation. They make use of realistic simulated galaxy catalogues that have…
12th VIPERS Science Meeting
Most of the Darklight team is gathering this week in Milan, together with the VIPERS Science Team, to discuss how to best use the 90,000 galaxy redshifts of the now completed VIPERS galaxy survey. The methods being developed by the ERC-funded Darklight project are allowing researchers to optimize the extraction of cosmological information from the large-scale galaxy distribution shown by…
