Title: | Discovery of a FR0 radio galaxy emitting at γ-ray energies | Authors: | GRANDI, PAOLA CAPETTI, Alessandro BALDI, RANIERI DIEGO |
Issue Date: | 2016 | Journal: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | Number: | 457 | Issue: | 1 | First Page: | 2 | Abstract: | We present supporting evidence for the first association of a Fermi source, 3FGLJ1330.0-3818, Acero et al. (2015) with the Fanaroff-Riley type 0 (FR 0) radio galaxy Tol1326-379. FR 0s represent the majority of the local population of radio-loud active galactic nuclei but their nature is still unclear. They share the same nuclear and host properties as FR Is, but they show a large deficit of extended radio emission. Here we show that FR 0s can emit photons at very high energies. Tol1326-379 has a GeV luminosity of L>1 GeV ∼ 2 × 1042 erg s-1, typical of FR Is, but with a steeper γ-ray spectrum (Γ = 2.78 ± 0.14). This could be related to the intrinsic jet properties but also to a different viewing angle. | URI: | http://hdl.handle.net/20.500.12386/26032 | URL: | http://arxiv.org/abs/1512.01242v1 https://academic.oup.com/mnras/article/457/1/2/988479 |
