X-ray polarization measurement of the gold standard of radio-quiet active galactic nuclei : NGC 1068

F. Marin, A. Marinucci, M. Laurenti +102

We used the Imaging X-ray Polarimetry Explorer (IXPE) satellite to measure, for the first time, the 2-8 keV polarization of NGC 1068. We pointed IXPE for a net exposure time of 1.1…

Globular Clusters Contribute to the Nuclear Star Cluster and Galaxy Center Gamma-Ray Excess, Moderated by Galaxy Assembly History

Yuan Gao, Hui Li, Xiaojia Zhang +2

Two unresolved questions at galaxy centers, namely the formation of the nuclear star cluster (NSC) and the origin of the gamma-ray excess in the Milky Way (MW) and Andromeda (M31),…

Polarized Blazar X-rays imply particle acceleration in shocks

Ioannis Liodakis, Alan P. Marscher, Iván Agudo +125

Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $\sim 1…
