Clustering with phylogenetic tools in astrophysics

, 2015
Phylogenetic approaches are finding more and more applications outside the field of biology. Astrophysics is no exception since an overwhelming amount of multivariate data has appeared in the last twenty years or so. In particular, the diversification of

Studying the evolution of large-scale structure with the VIMOS-VLT Deep Survey

, 2007
The VIMOS-VLT Deep Survey (VVDS) currently offers a unique combination of depth, angular size and number of measured galaxies among surveys of the distant Universe: ~ 11,000 spectra over 0.5 deg2 to I_{AB}=24 (VVDS-Deep), 35,000 spectra over ~ 7 deg2 to ...

The Need for Plasma Astrophysics in Understanding Life Cycles of Active Galaxies

, 2009
In this White Paper, we emphasize the need for and the important role of plasma astrophysics in the studies of formation, evolution of, and feedback by Active Galaxies. We make three specific recommendations: 1) We need to significantly increase the resolution of VLA, perhaps by building an EVLA-II at a modest cost.

Astrocladistics: Multivariate Evolutionary Analysis in Astrophysics

, 2009
The Hubble tuning fork diagram, based on morphology and established in the 1930s, has always been the preferred scheme for classification of galaxies. However, the current large amount of data up to higher and higher redshifts asks for more sophisticated

Morphological type correlation between nearest neighbor pairs of galaxies [PDF]

Although the morphological type of galaxies is one of the most fundamental properties of galaxies, its origin and evolutionary processes, if any, are not yet fully understood.

Astrophysics with the Sunyaev-Zel’dovich effect in clusters of galaxies

, 2020
Clusters of galaxies are unique systems in the universe. Being the largest gravitation- ally bound and virialized structures, they are “at the crossroads of astrophysics and cosmology”. They host three main components: galaxies; hot, optically-thin plasma and non-baryonic dark matter.
