Obscuring clouds playing hide-and-seek in the Active Nucleus H0557-385
A. L. Longinotti, S. Bianchi, L. Ballo +2
This paper reports on two XMM-Newton observations of the Seyfert 1 Galaxy H0557-385 obtained in 2006, which show the source at an historical low flux state, more than a factor of 1…
Thermal disc emission from a rotating black hole: X-ray polarization signatures
M. Dovciak, F. Muleri, R. W. Goosmann +2
Thermal emission from the accretion disc around a black hole can be polarized, due to Thomson scattering in a disc atmosphere. In Newtonian space, the polarization angle must be ei…
Tidal tails around globular clusters
M. Montuori, R. Capuzzo-Dolcetta, P. Di Matteo +1
We present the results of detailed N-body simulations of clusters moving in a realistic Milky Way (MW) potential. The strong interaction with the bulge and the disk of the Galaxy l…
IRAS 18511+0146: a proto Herbig Ae/Be cluster?
S. Vig, L. Testi, M. Walmsley +3
Context: The evolution of a young protocluster depends on the relative spatial distributions and dynamics of both stars and gas. Aims: We study the distribution and properties of t…
Combined Scanning Electron Microscope and Micro-InfraRed measurements on Interplanetary Dust Particles
A. Aronica, A. Rotundi, G. Ferrini +3
Laboratory characterization of Interplanetary Dust Particles (IDPs) collected in the lower stratosphere represents a concrete analysis of cosmic dust properties which played a fund…
Time-Evolving Photoionization: the Thin and Compact X-Ray Wind of NGC 4051
Fabrizio Nicastro, Yair Krongold, Martin Elvis +3
We discuss the power of time-evolving photoionization as a diagnostic tool to measure the electron density of photoionized gas. We apply this technique to a XMM-Newton observation…
