Multi-band infrared image (Blue=1μm, Green=1.3μm, Red=2.2μm) of the 1.7 square deg COSMOS field obtained with the ESO/VISTA telescope at Paranal Observatory. Total exposure time of 55 hours. More than 200,000 galaxies have been identified in this image. Credit: ESO/UltraVISTA Team/TERAPIX/CNRS/INSU/CASU.

The research activity of the group is focused on understanding the evolution of galaxies from the assembly epoch to the present time, and it is primarily based on the statistical analysis of multi-wavelength spectro-photometric data from large galaxy redshift surveys. We are especially interested in tracing the evolution of star formation activity in galaxies and understanding the processes that might trigger, regulate, or terminate it. Emphasis is given to the study of various star formation rate indicators, of the role of the environment and of active galactic nuclei in regulating galaxy evolution, of the transition from star-forming to passive galaxies. Our expertise includes the development of analysis tools to measure spectral properties, to characterize the spectral energy distribution of galaxies and active galactic nuclei from ultraviolet to far-infrared wavelengths using stellar synthesis population models, to study the evolution of metallicity and dust content in galaxies.

The main projects we are currently involved with include a number of ongoing (or recently completed) surveys, plus some future surveys still at the planning stage

VANDELS: a deep VIMOS survey of the CANDELS UDS and CDFS fields
Deep VLT spectroscopic survey of high-redshift galaxies in the CANDELS fields
with the VIMOS spectrograph, designed to produce high signal-to-noise spectra and
investigate the physiscs of galaxies in the early Universe.
VIPERS: the VIMOS Public Extragalactic Redshift Survey
An ESO Large Program survey with the VIMOS spectrograph, which has collected
some 90,000 galaxy redshift measurements over an area of 24 square degrees,
to study the details of the galaxies large-scale distribution.
VIPERS Home Page
VUDS: the VIMOS Ultra Deep Survey
An ESO Legacy Large Program designed to make a complete census of the star forming
galaxy population at 2 < z < 6.7 by observing 10000 galaxies with the VIMOS spectrograph.
VUDS Home Page
The MOONS extra-galactic survey (planned)
A spectroscopic survey being designed to primarily study galaxy evolution
in the redshift range 2 < z < 6
The Euclid spectroscopic survey (planned)
A spectroscopic survey being designed to primarily map the large-scale distribution
of galaxies in the redshift range 0.9 < z < 1.8 with observations of some
30 Million galaxies over 15,000 square degrees

Past spectroscopic surveys we have been involved with include

VVDS: the VIMOS VLT Deep Survey
The first spectroscopic survey carried out with the VIMOS spectrograph on the ESO/VLT.
It includes observations of some 35,000 galaxies in the redshift range 0 < z < 6.5
VVDS Home Page
zCOSMOS: the redshift survey in the COSMOS field
A combination of a Wide and a Deep survey, with observations of some 20,000
and XXXX galaxies, respectively, carried out with the VIMOS spectrograph.
MASSIV: the Mass Assembly Survey with SINFONI in VVDS
A high-resolution spectroscopic survey of 84 star-forming galaxies drawn from
the VVDS sample in the redshift range 0.9 < z < 2.2 designed to study the formation phase
of galaxy disks.
MASSIV Database
CLASH-VLT: a VLT survey of CLASH clusters
A spectroscopic survey of 14 massive clusters of galaxies in the redshift range
0.2 < z < 0.6, carried out with the VIMOS spectrograph.

Other survey projects some of us are (or were, until recently) involved with include

COSMOS: the Cosmic Evolution Survey
a multi-wavelength observational effort, covering an area of 2 square degrees with
observations from the X-rays (XMM-Newton and Chandra) and the UV (GALEX) to the optical
(from the ground using SUBARU and the CFHT, and from space using ACS on board HST),
the Near and Mid-infrared (Spitzer and Herschel), the sub-millimiter and the radio (VLA)
wavelengths. Over 2 million galaxies, spanning 75% of the age of the Universe, have been
detected by this project.
COSMOS Home Page
DustPedia: A Definitive Study of Cosmic Dust in the Local Universe
A study of dust content in nearby galaxies, based primarily on data from the Herschel
and Planck satellites
DustPedia Home Page
Two X-ray surveys carried out with XMM-Newton, designed to probe the large scale
distribution of clusters of galaxies out to z ~ 1, and of QSOs much further out.

We also develop new software tools for data reduction and analysis (see the Astronomical Software page).
