The evolution of dark matter substructure [PDF]

, 2001
This thesis investigates the dynamical evolution of systems orbiting within deeper potentials. Initially we use a simple satellite-halo interaction to study the dynamical processes that act on orbiting systems and we compare these results to analytical ...

Agn In Brightest Cluster Galaxies

, 2018
We present a systematic investigation of the nuclear activity in Brighest Cluster Galaxies through cosmic epochs. By combining X-ray, Radio, optical and IR data, we constrain the origin of the feeding gas and the accretion regime, as well as the feedback processes affecting the surrounding Intra Cluster Medium and star formation events in the BCGs ...

Spectral Energy Distribution Fitting of Globular Clusters in NGC 4874: Masses and Metallicities

The Astrophysical Journal
In most nearby galaxies, photometry of the integrated light of their globular clusters (GCs) has been obtained in only two filters, yielding just a single color index.

Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy

Astronomy & Astrophysics
Context. The Bullet Cluster (1E 0657–56), located at a redshift of 0.296, is among the best-known merging galaxy clusters and a key laboratory for dark matter studies.

Co-Evolution of Brightest Cluster Galaxies and Galaxy Activity in the Host Clusters

, 2009
We have identified ~500 relatively relaxed galaxy clusters at low redshift (z < 0.3) from the maxBCG catalog with double radio lobes at the center; about 200 radio counterparts of brightest cluster galaxies (BCGs) of these clusters appear to be wide ...

Feedback and brightest cluster galaxy formation

, 2005
We present deep optical imaging of the z 4: 1 radio galaxy TN J1338 - 1942, obtained using the Advanced Camera for Surveys ( ACS) on board the Hubble Space Telescope, as well as ground- based near- infrared imaging data from the European Southern ...

Internal dynamics of the galaxy cluster Abell 545. The ideal case where to study the simultaneous formation of a galaxy system and its brightest galaxy

, 2011
Context. The mechanisms giving rise to diffuse radio emission in galaxy clusters, and in particular their connection with cluster mergers, are still debated.

Constraining dark energy using real and mock galaxy surveys [PDF]

, 2009
In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

Extended Radio Emission in the Perhipheral Regions of the Shapley Concentration Core

Galaxies, 2017
The Shapley Concentration (SC) is a galaxy supercluster (few tens of degrees) in the Local Universe (<z>∼0.048) which is currently undergoing cluster mergers and group accretion.
