The Galactic Halo density distribution from photometric survey data: results of a pilot study
M. Cignoni, V. Ripepi, M. Marconi +4
Our goal is to recover the Galactic Halo spatial density by means of field stars. To this aim, we apply a new technique to the Capodimonte Deep Field (OACDF, Alcala' et al. 2004),…
Gravitational lensing by cosmic strings: what we learn from the CSL-1 case
M. V. Sazhin, O. S. Khovanskaya, M. Capaccioli +5
Cosmic strings were postulated by Kibble in 1976 and, from a theoretical point of view, their existence finds support in modern superstring theories, both in compactification model…
Shapley Optical Survey II: The effect of environment on the colour-magnitude relation and galaxy colours
C. P. Haines, P. Merluzzi, A. Mercurio +5
We present an analysis of the effects of environment on the photometric properties of galaxies in the core of the Shapley Supercluster at z=0.05, one of the most massive structures…
The true nature of CSL-1
M. V. Sazhin, M. Capaccioli, G. Longo +5
On January 12 2006, the Hubble Space Telescope observed the peculiar double extragalactic object CSL-1, suspected to be the result of gravitational lensing by a cosmic string. The…
Stellar kinematics for the central spheroid in the Polar Disk Galaxy NGC4650A
E. Iodice, M. Arnaboldi, R. P. Saglia +7
We have obtained high angular resolution, high signal-to-noise spectra of the Calcium triplet absorption lines on the photometric axes of the stellar spheroid in the polar disk gal…
