The cylindrical jet base of M87 within 100 of the central engine
Brian Punsly
A recent article on high-resolution 86 GHz observations with the Global Millimeter VLBI Array, the phased Atacama Large Millimeter/submillimeter Array, and the Greenland Telescope…
The Details of Limb Brightening Reveal the Structure of the Base of the Jet in M\,87 for the First Time
Brian Punsly
It has become commonplace is astronomy to describe the transverse coarse structure of jets in loosely defined terms such as "sheath" and "spine" based on discussions of parsec scal…
The Energetics of the Central Engine in the Powerful Quasar, 3C298
Brian Punsly, Christian Groeneveld, Gary J. Hill +3
The compact steep spectrum radio source, 3C 298, (redshift of 1.44) has the largest 178 MHz luminosity in the 3CR (revised Third Cambridge Catalogue) catalog; its radio lobes are a…
Observing the Time Evolution of the Multi-Component Nucleus of 3C\,84
Brian Punsly, Hiroshi Nagai, Tuomas Savolainen +1
The advent of global mm-band Very Long Baseline Interferometry (VLBI) in recent years has finally revealed the morphology of the base of the two most prominent nearby, bright, extr…
The Energetics of Launching the Most Powerful Jets in Quasars: A Study of 3C82
Brian Punsly, Gary J. Hill, Paola Marziani +5
3C 82 at a redshift of 2.87 is the most distant 3C (Third Cambridge Catalogue) quasar. Thus, it is a strong candidate to have the most luminous radio lobes in the Universe. 3C 82 b…
Constraints on Black Hole Jet Models Used As Diagnostic Tools of Event Horizon Telescope Observations of M87
Brian Punsly
Jet models of Event Horizon Telescope (EHT) data should also conform to the observed jet profiles just downstream. This study evaluates conformance of models of black hole jets to…
