Spatial and observational homogeneities of the galaxy distribution in standard cosmologies
L. J. Rangel Lemos, Marcelo B. Ribeiro
This work discusses the possible empirical verification of the geometrical concept of homogeneity of the standard relativistic cosmology considering its various definitions of dist…
Self-consistent simulations of Nuclear Cluster formation through Globular Cluster orbital decay and merging
R. Capuzzo-Dolcetta, P. Miocchi
We present results of fully self-consistent N-body simulations of the motion of four globular clusters moving in the inner region of their parent galaxy. With regard to previous si…
The X-ray view of the ionization cone in NGC5252
Matteo Guainazzi, Stefano Bianchi, Massimo Cappi +2
We present the results of a Chandra soft X-ray observation of the spectacular ionization cone in the nearby Seyfert 2 galaxy NGC 5252. As almost invariably observed in obscured AGN…
A Spitzer IRS Low-Resolution Spectroscopic Search for Buried AGNs in Nearby Ultraluminous Infrared Galaxies - A Constraint on Geometry between Energy Sources and Dust -
Masatoshi Imanishi, C. C. Dudley, Roberto Maiolino +3
We present the results of Spitzer IRS low-resolution infrared 5-35 micron spectroscopy of nearby ultraluminous infrared galaxies (ULIRGs) at z < 0.15. We focus on the search for th…
X-ray Astronomical Polarimetry in the XEUS Era
E. Costa, P. Soffitta, G. Di Persio +9
X-ray Polarimetry is almost as old as X-ray Astronomy. Since the first discovery of X-ray sources theoretical analysis suggested that a high degree of linear polarization could be…
Study of X-ray reflection features in a sample of Sy 1s observed by BeppoSAX
A. De Rosa, A. C. Fabian, L. Piro +1
The ionized disc reflection model of Ross & Fabian is applied to a sample of five Seyfert 1 galaxies observed by BeppoSAX. Good fits were obtained for all the objects in the sample…
