X-ray and weak lensing measurements of the mass profile of MS1008.1-1224: Chandra and VLT data
S. Ettori, M. Lombardi
We analyse the Chandra dataset of the galaxy cluster MS1008.1-1224 to recover an estimate of the gravitating mass as function of the radius and compare these results with the weak…
HST observations of the metal rich globular clusters NGC6496 and NGC6352
L. Pulone, G. De Marchi, S. Covino +1
Deep exposures of the metal-rich globular clusters NGC6496 and NGC6352 were obtained with the WFPC2 camera on board the HST through the F606W and F814W filters. The resulting colou…

A. Vikhlinin, A. Voevodkin, C. R. Mullis +8
We present a new method for deriving cosmological constraints based on the evolution of the baryon mass function of galaxy clusters, and implement it using 17 distant clusters from…
Major Mergers of Haloes, Growth of Massive Black Holes and Evolving Luminosity Function of Quasars
Evanthia Hatziminaoglou, Guy Mathez, Jose-Maria Solanes +2
We construct a physically motivated analytical model for the quasar luminosity function, based on the joint star formation and feeding of massive black holes suggested by the obser…
