Semiclassical collapse of a sphere of dust

Roberto Casadio, Giovanni Venturi

The semiclassical collapse of a homogeneous sphere of dust is studied. After identifying the independent dynamical variables, the system is canonically quantised and coupled equati…

Branching Interfaces with Infinitely Strong Couplings

Giovanni Sartoni, Attilio L. Stella

A hierarchical froth model of the interface of a random $q$ -state Potts ferromagnet in $2 D$ is studied by recursive methods. A fraction $p$ of the nearest neighbour bonds is made i…

The accelerated observer and quantum effects

Roberto Casadio, Giovanni Venturi

An extended monopole detector at constant acceleration coupled to a massless scalar field is allowed to evolve quantum mechanically. It is found that while in the classical, follow…

Black hole and the adiabatic phase

Roberto Casadio, Giovanni Venturi

An open system consisting of a scalar field bound to a Kerr black hole whose mass ( $M$ ) and specific angular momentum ( $a$ ) are slowly (adiabatically) perturbed is considered. The…

Ground states for a class of deterministic spin models with glassy behaviour

I. Borsari, S. Graffi, F. Unguendoli

We consider the deterministic model with glassy behaviour, recently introduced by Marinari, Parisi and Ritort, with \ha\ $H = \sum_{i, j = 1}^{N} J_{i, j} σ_{i} σ_{j}$ , where $J$ is the discrete…

Generalized KdV and Quantum Inverse Scattering Description of Conformal Minimal Models

Davide Fioravanti, Francesco Ravanini, Marian Stanishkov

We propose an alternative description of 2 dimensional Conformal Field Theory in terms of Quantum Inverse Scattering. It is based on the generalized KdV systems attached to $A_2^{(…

Dynamical Families in the Galacti Globular Cluster System

M. Bellazzini, E. Vesperini, F. Fusi Pecci +1

The Halo Galactic Globular Clusters (GCs) lying inside the solar circle (\inn, \r $< 8 K p c$ , \feh $< - 0.8$ ) are shown to keep no record of the strong correlation between GC absolute…

The energetics of flat and rotating early-type galaxies and their X-ray luminosity

L. Ciotti, S. Pellegrini

The global energy budget of the hot gas flows in early-type galaxies is used to explain the recent observational results that S0 galaxies have lower mean X-ray luminosity $L_{X}$ per…

A Procedure to Calibrate a Multi-Modular Telescope

P. F. Mastinu, P. M. Milazzo, M. Bruno +1

A procedure has been developed for the charge, mass and energy calibration of ions produced in nuclear heavy ion reactions. The charge and mass identification are based on a $Δ$ E-E…

Is the X-ray spectrum of the Seyfert 2 galaxy NGC5252 intrinsically flat?

M. cappi, T. Mihara, M. Matsuoka +3

The first X-ray observation of the Seyfert 2 galaxy NGC5252 is reported. ASCA collected $\sim 4000$ photons/detector enough to perform an accurate spectral analysis of this source.…

Environmental effects on the structure of the Dwarf Spheroidal Galaxies

M. Bellazzini, F. Fusi Pecci, F. R. Ferraro

The central surface brightness ( $μ_{V} (0)$ ) of the dwarf spheroidal satellites of our own Galaxy is found to correlate with their distance from the Galactic Center ( $R_{GC}$ ). This o…

The Kinematics of Emission-Line Galaxies in Clusters from ENACS

A. Biviano, P. Katgert, A. Mazure +3

By using the ENACS data, we have studied the properties of emission-line galaxies (ELG) in clusters. The fraction of ELG in clusters is 16~%; this fraction is slightly dependent on…

F. Abe

We report on measurements of differential $μ - b ˉ$ cross sections, where the muon is from a semi-leptonic $b$ decay and the $b ˉ$ is identified using precision track reco…

Spatial and Luminosity Properties of the Perseus-Pisces Redshift Survey

F. Sylos Labini, M. Montuori, L. Pietronero

We analyze the spatial and the luminosity properties of the Perseus-Pisces redshift survey. We find that the two point correlation function (CF) $Γ (r)$ is a power law up to the sam…
