Do Reverberation Mapping Analyses Provide an Accurate Picture of the Broad Line Region?
S. W. Mangham, C. Knigge, P. Williams +6
Reverberation mapping (RM) is a powerful approach for determining the nature of the broad-line region (BLR) in active galactic nuclei. However, inferring physical BLR properties fr…
On the maximum energy of non-thermal particles in the primary hotspot of Cygnus A
Anabella T. Araudo, Anthony R. Bell, Katherine M. Blundell +1
We study particle acceleration and magnetic field amplification in the primary hotspot in the northwest jet of radiogalaxy Cygnus A. By using the observed flux density at 43 GHz in…
Cosmic Ray Acceleration by Relativistic Shocks: Limits and Estimates
AR Bell, AT Araudo, JH Matthews +1
We examine limits to the energy to which cosmic rays can be accelerated by relativistic shocks, showing that acceleration of light ions as high as 100 EeV is unlikely. The implicat…
The reverberation signatures of rotating disc winds in active galactic nuclei
S. W. Mangham, C. Knigge, J. H. Matthews +3
The broad emission lines (BELs) in active galactic nuclei (AGN) respond to ionizing continuum variations. The time and velocity dependence of their response depends on the structur…
Quasar emission lines as probes of orientation: implications for disc wind geometries and unification
James H. Matthews, Christian Knigge, Knox S. Long
The incidence of broad absorption lines (BALs) in quasar samples is often interpreted in the context of a geometric unification model consisting of an accretion disc and an associa…
