We adopted innovative observing and mapping techniques providing unprecedented accuracy for single-dish imaging of SNRs at these frequencies, revealing morphological details typically available only at lower frequencies through interferometry observations. High-frequency studies of SNRs in the radio range are useful to better characterize the spatially-resolved spectra and the physical parameters of different regions of the SNRs interacting with the ISM. Furthermore, synchrotron-emitting electrons in the high-frequency radio band are also responsible for the observed high-energy phenomenology as -e.g.- Inverse Compton and bremsstrahlung emission components observed in gamma-rays, to be disentangled from hadron emission contribution (providing constraints on the origin of cosmic rays). | Titolo del convegno: | Supernova Remnants: An Odyssey in Space after Stellar Death | Luogo del convegno: | Chania, Grecia | Periodo del convegno: | 6-11 giugno 2016 | URI: | http://hdl.handle.net/20.500.12386/24977 | URL: | https://arxiv.org/pdf/1609.03882.pdf http://snr2016.astro.noa.gr/homepage.php/proceedings/ |
