Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes II. Evidence for coronal emission
M. Marongiu, A. Pellizzoni, S. Righini +43
One of the most important objectives of solar physics is the physical understanding of the solar atmosphere, the structure of which is also described in terms of the density (N) an…
On the interplay between turbulent forces and neoclassical particle losses in Zonal Flow dynamics
R. Gerrú, S. Mulas, U. Losada +5
This study presents the investigation of the connection between radial electric field, gradient of Reynolds stress and Long Range Correlation (LRC), as a proxy for Zonal Flows (ZF)…
Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes I: solar radius
M. Marongiu, A. Pellizzoni, S. Mulas +32
The Sun is an extraordinary workbench, from which several fundamental astronomical parameters can be measured with high precision. Among these parameters, the solar radius $R_{\odo…
Solar observations with single-dish INAF radio telescopes: continuum imaging in the 18-26 GHz range
A. Pellizzoni, S. Righini, M. N. Iacolina +28
We present a new solar radio imaging system implemented through the upgrade of the large single-dish telescopes of the Italian National Institute for Astrophysics (INAF), not origi…
Investigating the high-frequency spectral features of SNRs Tycho, W44 and IC443 with the Sardinia Radio Telescope
S. Loru, A. Pellizzoni, E. Egron +20
The main characteristics in the radio continuum spectra of Supernova Remnants (SNRs) result from simple synchrotron emission. In addition, electron acceleration mechanisms can shap…
Imaging of SNR IC443 and W44 with the Sardinia Radio Telescope at 1.5 GHz and 7 GHz
E. Egron, A. Pellizzoni, M. N. Iacolina +33
Observations of supernova remnants (SNRs) are a powerful tool for investigating the later stages of stellar evolution, the properties of the ambient interstellar medium, and the ph…
A model for the fast evaluation of prompt losses of energetic ions in stellarators
J. L. Velasco, I. Calvo, S. Mulas +4
A good understanding of the confinement of energetic ions in non-axisymmetric magnetic fields is key for the design of reactors based on the stellarator concept. In this work, we d…
A quasi-isodynamic configuration with good confinement of fast ions at low plasma
E. Sánchez, J. L. Velasco, I. Calvo +1
A new quasi-isodynamic stellarator configuration optimized for the confinement of energetic ions at low plasma is obtained. The numerical optimization is carried out using the…
New high-frequency radio observations of the Cygnus Loop supernova remnant with the Italian radio telescopes
S. Loru, A. Pellizzoni, E. Egron +19
Supernova remnants (SNRs) represent a powerful laboratory to study the Cosmic-Ray acceleration processes at the shocks, and their relation to the properties of the circumstellar me…
Broadband radio study of the supernova remnant Kes 73
S. Loru, A. Ingallinera, A. Pellizzoni +16
Strong shocks occurring in supernova remnants (SNRs), and their interaction with an often anisotropic surrounding medium, make SNRs ideal laboratories for studying the production a…
Observations of Supernova Remnants with the Sardinia Radio Telescope
E. Egron, A. Pellizzoni, S. Loru +11
In the frame of the Astronomical Validation activities for the 64m Sardinia Radio Telescope, we performed 5-22 GHz imaging observations of the complex-morphology supernova remnants…
