On the X-ray feature associated with the Guitar Nebula
Rino Bandiera
Context: A mysterious X-ray nebula, showing a remarkably linear geometry, was recently discovered close to the Guitar Nebula, the bow-shock nebula associated with B2224+65, which i…
The nature of the X-ray halo of the plerion G21.5-0.9 unveiled by XMM-Newton and Chandra
F. Bocchino, E. van der Swaluw, R. Chevalier +1
The nature of the radio-quiet X-ray halo around the plerionic SNR G21.5-0.9 is under debate. On the basis of spatial and spectral analysis of a large Chandra and XMM-Newton dataset…
Can hidden correlations mimic a variable fine structure constant?
Rino Bandiera, Edvige Corbelli
Murphy et al. (2003a, MNRAS, 345, 609) claim to find evidence of cosmological variations of the fine structure constant in the spectra of intervening QSO absorption line system…
Magnetic Rayleigh-Taylor instability for Pulsar Wind Nebulae in expanding Supernova Remnants
N. Bucciantini, E. Amato, R. Bandiera +2
We present a numerical investigation of the development of Rayleigh-Taylor instability at the interface between an expanding Pulsar Wind Nebula and its surrounding Supernova Remnan…
The effects of spin-down on the structure and evolution of pulsar wind nebulae
N. Bucciantini, R. Bandiera, J. M. Blondin +2
We present high resolution spherically symmetric relativistic magnetohydrodynamical simulations of the evolution of a pulsar wind nebula inside the free expanding ejecta of the sup…
Analytic Solutions for the Evolution of Radiative Supernova Remnants
R. Bandiera, O. Petruk
We present the general analytic solution for the evolution of radiative supernova remnants in a uniform interstellar medium, under thin-shell approximation. This approximation is s…
The X-ray Halo of G21.5-0.9
R. Bandiera, F. Bocchino
The emission of the plerion G21.5-0.9 appears more extended in X rays than in radio. This is an unexpected result because it would imply that short-lived X-ray electrons may reach…
BeppoSAX observation of the composite remnant G327.1-1.1
F. Bocchino, R. Bandiera
We report an X-ray study of the composite supernova remnant G327.1-1.1, with particular emphasis on its thermal emission. By virtue of a combined spatial and spectral analysis, we…
A catalogue of damped Lyman alpha absorption systems and radio flux densities of the background quasars
S. J. Curran, J. K. Webb, M. T. Murphy +3
We present a catalogue of the 322 damped Lyman alpha absorbers taken from the literature. All damped Lyman alpha absorbers are included, with no selection on redshift or quasar mag…
The Crab Nebula at 1.3 mm: evidence for a new synchrotron component
Rino Bandiera, Roberto Neri, Riccardo Cesaroni
We present the results of 1.3 mm observations of the Crab Nebula, performed with the MPIfR bolometer arrays at the IRAM 30-m telescope. The maps obtained, of unprecedented quality…
Implications of the synchrotron emission in plerionic nebulae: a second component in the Crab Nebula
Rino Bandiera
High-quality spatially resolved spectra of synchrotron emission from plerions represent a powerful diagnostic tool for the physical conditions in these objects. A fundamental quest…
The effects of an ionizing background on the HI column density distribution in the local Universe
Edvige Corbelli, Rino Bandiera
Using data on the HI column density distribution in the local Universe, f(N_{HI}), we show how to determine g(N_{H}), the distribution of the total gas (HI+HII) column density. A s…
A Comprehensive Statistical Analysis of the Gas Distribution in Lyman-limit and Damped Lyman-alpha Absorption Systems
Rino Bandiera, Edvige Corbelli
In this paper we show how to use data on Lyman-limit and Damped Lyman-alpha absorption systems to derive the hydrogen ionization fractions and the distribution of the face-on total…
Sharp HI edges at high z: the gas distribution from Damped Lyman-alpha to Lyman-limit absorption systems
Edvige Corbelli, Edwin E. Salpeter, Rino Bandiera
We derive the distribution of neutral and ionized gas in high redshift clouds which are optically thick to hydrogen ionizing radiation, using published data on Lyman-limit and Damp…
Properties of the Non-Thermal Emission in Plerions
Rino Bandiera
The synchrotron emission observed in plerions depends on the characteristics of the magnetic fields and relativistic electrons in these supernova remnants. Therefore an analysis of…
A model for the spatial distribution of relativistic electrons in the Crab Nebula
E. Amato, M. Salvati, R. Bandiera +2
We extend Pacini & Salvati's model for the synchrotron emission from plerions to allow more realistic predictions of the surface brightness profiles of the Crab Nebula at radio, op…
The Supernova Remnant G11.2-0.3 and its central Pulsar
R. Bandiera, F. Pacini, M. Salvati
The plerion inside the composite Supernova Remnant G11.2-0.3 appears to be dominated by the magnetic field to an extent unprecedented among well known cases. We discuss its evoluti…
Modelling Non-Axisymmetric Bow Shocks
Rino Bandiera
I present an extension of the thin layer approximation to non-axisymmetric bow shocks. By choosing a suitable set of curvilinear coordinates that matches the geometry of a generall…
