    The Black Hole Masses in Galactic Nuclei

    We review recent progress in dynamically measuring the black hole masses in nearby galactic nuclei. Some of the outstanding issues for both the gas disk and stellar dynamical methods are outlined and the impac...

    Spectroscopy of CSS Sources

    Since their discovery, CSS and GPS sources have been growing in relevance. Although their nature is still not well understood, the latest studies show that these sources may be the progenitors of the large-sca...

    Evidence for Magnetic Fields in the Outflow from T Tau S

    We have observed at 5GHz the T Tau system with high resolution (≲ 0”.1) using the Multi-Element Radio Linked Interferometer (MERLIN) based at Jodrell Bank Both the optical star (T Tau N) and its well-known inf...

    The Role of Shocks in the Extended Emission Line Regions of Powerful Radio Galaxies

    A detailed optical spectroscopic study of the extended line-emitting gas in a sample of powerful radio galaxies has revealed clear evidence that fast shocks have a major impact on the state of the warm gas alo...

    IRAS 0421+0400: A Curious Spiral with Flaring Jets

    We present new VLA observations of IRAS 0421+0400 at 1.4 and 5 GHz, providing dual frequency information and higher resolution than previously available. We find extremely accurate alignment of the central dou...

    Radio and Optical Observations of the Nuclei of Sbc Galaxies

    A sample of 100 Sbc galaxies is being observed at different wavelengths and with high resolution, in order to obtain information about the physical process happening in their nuclei. We present here the compar...

    The interaction of radio jets with the narrow line region in Seyfert galaxies

    Long-slit spectroscopic observations of Seyfert galaxies reveal sub-structure in the [OIII] λ5007 emission-line profile. The sub-structure is spatially resolved and located close to the position of the near-nucle...

    The Discovery of Blazar-Type Nuclei in Two nearby Radio Ellipticals

    Near infrared polarimetry of Centaurus A and IC5063 has revealed the existence of a steep spectrum highly polarized source in the nuclei of both galaxies. The position angle of polarization is perpendicular to...

    Young Supernovae in the Starburst Galaxy M82

    MERLIN observations at 1666 MHz detect 18 compact (< 0.25 arcsec) radio sources within the central few hundred parsecs of M82. M82 is well known as a ‘starburst’ galaxy, and it is probable that these objects a...
