CENTAURUS A: THE EXTRAGALACTIC SOURCE OF COSMIC RAYS WITH ENERGIES ABOVE THE KNEE
(IOP PUBLISHING LTDBRISTOL, 2012)
The origin of cosmic rays at all energies is still uncertain. In this paper, we present and explore an astrophysical scenario to produce cosmic rays with energy ranging from below 10(15) to 3 x 10(20) eV. We show here that ...
The γ -ray sky seen at X-ray energies: II. The Swift hunt of Fermi BL Lac objects among unidentified γ -ray sources
(EDP Sciences, 2020-06)
Context. Nearly 50% of all sources detected by the Fermi Large Area Telescope are classified as blazars or blazar candidates, one of the most elusive classes of active galaxies. Additional blazars can also be hidden within ...
XMM-Newton observations of NGC 3268 in the Antlia Galaxy Cluster: characterization of a hidden group of galaxies at z ~0.41
(Oxford University Press, 2018-09)
We report on a detailed X-ray study of the extended emission of the intracluster medium (ICM) around NGC3268 in the Antlia Cluster of galaxies, together with a characterization of an extended source in the field, namely a ...
Signatures of feedback in the spectacular extended emission region of NGC 5972
(2023)
We present Chandra X-ray Observatory observations and Space Telescope Imaging Spectrograph spectra of NGC 5972, one of the 19 ‘Voorwerpjes’ galaxies. This galaxy contains an extended emission-line region (EELR) and an ...
