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 …
A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet fortuitously aligns with our line of sight, the overall brightness is Doppler boosted by several …

The Large Area Telescope (LAT) on board the Fermi Gamma Ray Space Telescope, launched on 2008 June 11, provides unprecedented sensitivity in the γ-ray band (20 MeV to …
We describe the parsec-scale kinematics of 200 active galactic nucleus (AGN) jets based on 15 GHz Very Long Baseline Array (VLBA) data obtained between 1994 August 31 and 2011 …

We present the first catalog of active galactic nuclei (AGNs) detected by the Large Area Telescope (LAT), corresponding to 11 months of data collected in scientific operation mode …
Accreting supermassive black holes at the centres of active galaxies often produce 'jets'— collimated bipolar outflows of relativistic particles. Magnetic fields probably play a critical …
We present 15 GHz stacked VLBA images of 373 jets associated with active galactic nuclei (AGNs) having at least five observing epochs within a 20 yr time interval 1994–2015 from …
