ERC 10th Anniversary

FROM THE ERC WEBSITE: Imagine developing new anticancer therapies or tackling Parkinson’s disease? Or discovering Earth-like worlds in outer space? Can research develop batteries that make our mobile devices last longer? This is the type of cutting-edge research that the EU is promoting through the European Research Council (ERC), set up ten years ago. Some 7,000...

Darklight is moving!

Following Dr. Guzzo’s appointment as Full Professor on September 1st, 2016, the University of Milan has become the new coordinating host institution of the ERC project.

PI, post-docs and PhD students will be based at the Physics Department in Via Celoria 16 from the beginning of November, where they will have the...

DEMNUni: ISW, Rees-Sciama, and weak-lensing in the presence of massive neutrinos

In the July 2016 issue of JCAP, for the first time in the literature, Darklight fellow Dr. Carmelita Carbone and co-authors present a full reconstruction of the total (linear and non-linear) ISW/Rees-Sciama effect in the presence of massive neutrinos, together with its cross-correlations with CMB-lensing and weak-lensing signals. The present analyses make use...

BAO & RSD: dark light on obscure acronyms

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...

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...

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...

Science with LSS and CMB Cross-Correlations

The workshop took place on September 23rd 2015, in the POE hall of the Astronomical Observatory of Brera in Merate. It was broadly focused on the combination of two key cosmological probes, i.e. the large-scale galaxy distribution and the Cosmic Microwave Background (CMB), and included also recent results from projects such as Planck, POLARBEAR...

XC in N-body Simulations with neutrinos

demnuniDuring a 1-day workshop in Merate on Wednesday, September 23rd, 2015, Darklight post-doc fellow Carmelita Carbone will present the first set of cosmological simulations produced within the “Dark Energy and Massive Neutrino Universe” (DEMNUni) project. These simulations are characterized by L=2Gpc/h, Npart=2x2048^3, a baseline LCDM-Planck cosmology,...

Astronomy in the era of the LSST

In the week 24-28 November, Prof. Andy Connolly from the University of Washington (Seattle, USA) visited the Darklight group in Merate, delivering a beautiful talk on the Large Synoptic Survey Telescope (LSST). This is one of the most exciting galaxy survey projects of the next decade, entailing the construction of a dedicated 8m telescope with...

Voids in VIPERS

Cosmic voids, the largest component by volume of the cosmic web, are almost completely  empty regions of space, containing very few galaxies and very low densities of dark matter.

Dark Energy or Modified Gravity?

Different gravity models are degenerate when looking at the expansion history of the Universe H(z) only. Such degen eracy, can be lifted if we focus on the gravity­‐driven growth of cosmological structures, measuring the growth rate f(z). “Redshiſt-­‐Space Distortions” (RSDs), quantified through the two-­point correlation function (2PCF) are a potentially powerful way to extract this information. Yet, separating the linear RSD signal,...
