The Radio Wave Phase Imager uses monitoring and recording concepts, such as Software Defined Radio (SDR), to image Earth’s atmosphere. The Long Wavelength Array (LWA), New Mexico Observatory is considered a high-resolution camera that obtains phase

M87 is the best source in which to study a jet at high resolution in gravitational units because it has a very high mass black hole and is nearby. The angular size of the black hole is second only to Sgr A*, which does not have a strong jet. The jet

The nearby E0 galaxy M87 in the Virgo Cluster contains one of the nearest examples of a powerful non-thermal jet source. In addition, HST spectroscopy of its nucleus give strong evidence for the presence of a ≈3×109 M⊙ central black hole (corres

Over the course of the 3 day meeting, attendees reviewed the current states of the art in adaptive optics (AO) and optical interferometry (OI) and investigated the synthesis of these techniques that will be necessary for the next-generation of high a

Adaptive Optics.
Nematic liquid crystal spatial light modulators (LC-SLMs) have been proposed as wavefront correctors for adaptive optics (a summary of which is described in ref. 1 and references therein). For example, at the last OSA/ESO meeting on adaptive optics i

The results of polarimetric λλ6,4 cm VLBA observations of the inner 5pc of the jet and core of Vir A (3C274, J1230+1223) are reported. At λ4 cm, the core and the inner parsec are unpolarized and there is evidence for ordered magnetic fields and la
