How to improve the High Frequency capabilities of SRT
T. Pisanu, M. Morsiani, C. Pernechele +2
The SRT (Sardinia Radio Telescope) is a general purpose, fully steerable, active surface equipped, 64 meters antenna, which is in an advanced construction state near Cagliari (Sard…
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…
Sardinia Radio Telescope: General Description, Technical Commissioning and First Light
P. Bolli, A. Orlati, L. Stringhetti +35
In the period 2012 June - 2013 October, the Sardinia Radio Telescope (SRT) went through the technical commissioning phase. The characterization involved three first-light receivers…
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…
