The nuclei of most normal galaxies contain supermassive black holes, which can accrete
gas through a disk and become active. These active galactic nuclei (AGNs) can form jets that …

Collimated outflows (jets) appear to be a ubiquitous phenomenon associated with the
accretion of material onto a compact object. Despite this ubiquity, many fundamental physics …

We present measurements of the properties of the central radio source in M87 using Event
Horizon Telescope data obtained during the 2017 campaign. We develop and fit geometric …

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 around 1 TeV …

The magnetic-field conditions in astrophysical relativistic jets can be probed by
multiwavelength polarimetry, which has been recently extended to X-rays. For example, one …

The central radio source in M87 provides the best opportunity to study jet formation because
it has a large angular size for the gravitational radius of the black hole and has a bright jet …

We analyze the parsec-scale jet kinematics from 2007 June to 2013 January of a sample of
γ-ray bright blazars monitored roughly monthly with the Very Long Baseline Array at 43 GHz …

The author presents a model for variability of the flux and polarization of blazars in which
turbulent plasma flowing at a relativistic speed down a jet crosses a standing conical shock …

ABSTRACT The Large Area Telescope (LAT) aboard the Fermi Gamma-ray Space
Telescope provides an unprecedented opportunity to study gamma-ray blazars. To …
