CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe shock waves of supernova remnants (SNRs) are prime candidates for cosmic-ray accelerators. A general feature of the blast wave is an extended shell visible in GeV and TeV gamma rays. HESS J1912+101 is a bright unassociated extended TeV source with a shell-like structure. This source has no counterparts at other wavelengths so far, hence it is still labeled as 'SNR candidate'. We are going to present the results of a deep observation campaign with the MAGIC telescopes together with 10 years of PASS 8 Fermi-LAT data. In order to analyze the data, we use a new 2D likelihood software called SkyPrism that allows parametrization of the morphology measured by MAGIC. We measure a joint Fermi-MAGIC flux spectrum covering three decades of energy. This spectrum is well fitted by a power-law with a hard spectral index and a cut-off at a couple TeV.

| Abstract: | The shock waves of supernova remnants (SNRs) are prime candidates for cosmic-ray accelerators. A general feature of the blast wave is an extended shell visible in GeV and TeV gamma rays. HESS J1912+101 is a bright unassociated extended TeV source with a shell-like structure. This source has no counterparts at other wavelengths so far, hence it is still labeled as 'SNR candidate'. We are going to present the results of a deep observation campaign with the MAGIC telescopes together with 10 years of PASS 8 Fermi-LAT data. In order to analyze the data, we use a new 2D likelihood software called SkyPrism that allows parametrization of the morphology measured by MAGIC. We measure a joint Fermi-MAGIC flux spectrum covering three decades of energy. This spectrum is well fitted by a power-law with a hard spectral index and a cut-off at a couple TeV. |
