Sheared helical turbulence and the helicity constraint in large-scale dynamos
A. Bigazzi, A. Brandenburg, K. Subramanian
The effect of shear on the growth of large scale magnetic fields in helical turbulence is investigated. The resulting large-scale magnetic field is also helical and continues to ev…
On the use of a heterogeneous MIMD-SIMD platform to simulate the dynamics of globular clusters with a central massive object
R. Capuzzo-Dolcetta, N. Pucello, V. Rosato +1
The dynamics of a large stellar (globular) cluster containing N=128,000 stars has been simulated by a direct summation (O(N)) method by using a heterogeneous platform. Prelimin…
Effects of the X-ray emission from young stars on the ionization level of a fractal star forming cloud
Andrea Lorenzani, Francesco Palla
We present the initial results of a study aimed at computing the global effects of the X-ray ionization due to young stars within a molecular cloud that forms stars with a standard…
Optical spectral variability of PG QSOs
D. Trevese, F. Vagnetti
In previous studies we have shown that the optical variability of quasars increases, on average, with redshift. We explained this dependance in terms of a hardening of the spectrum…
Anatomy of giant spiral galaxies
E. Pignatelli, G. Galletta
We present B and I band photometry, gas and star kinematics and 3D modelling of 7 giant spiral galaxies. The stellar systems studied have morphological types spanning from S0/a to…
Broad band properties of medium and low Lx/Lb Early Type Galaxies
G. Trinchieri, S. Pellegrini, A. Wolter +2
We have measured the spectral properties of five galaxies of low to intermediate Lx/Lb ratios with BeppoSAX and ASCA. A hard component (kT ~4-10 keV) is observed in all galaxies. I…
