Variability and Proper Motion of X-ray Knots in the Jet of Centaurus A

Bradford Snios, Sarka Wykes, Paul E. J. Nulsen +8

We report results from Chandra observations analyzed for evidence of variability and proper motion in the X-ray jet of Centaurus A. Using data spanning 15 years, collective proper…

UHECR propagation from Centaurus A

Sarka Wykes, Andrew M. Taylor, Justin D. Bray +2

In the light of the recently predicted isotopic composition of the kpc-scale jet in Centaurus A, we re-investigate whether this source could be responsible for some of the ultra-hi…

Ultrahigh-energy neutrino follow-up of Gravitational Wave events GW150914 and GW151226 with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +410

On September 14, 2015 the Advanced LIGO detectors observed their first gravitational-wave (GW) transient GW150914. This was followed by a second GW event observed on December 26, 2…

Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy

The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +447

We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Au…

Azimuthal asymmetry in the risetime of the surface detector signals of the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +436

The azimuthal asymmetry in the risetime of signals in Auger surface detector stations is a source of information on shower development. The azimuthal asymmetry is due to a combinat…

Internal entrainment and the origin of jet-related broad-band emission in Centaurus A

Sarka Wykes, Martin J. Hardcastle, Amanda I. Karakas +1

The dimensions of Fanaroff-Riley class I jets and the stellar densities at galactic centres imply that there will be numerous interactions between the jet and stellar winds. These…

Mass entrainment and turbulence-driven acceleration of ultra-high energy cosmic rays in Centaurus A

Sarka Wykes, Judith H. Croston, Martin J. Hardcastle +8

Observations of the FR I radio galaxy Centaurus A in radio, X-ray and gamma-ray bands provide evidence for lepton acceleration up to several TeV and clues about hadron acceleration…
