The brighter water masers of NGC 1068 appear to trace molecular gas in a parsec-scale disk surrounding the central engine. We find evidence that these masers are reverberating in response to a central, common pump source, presumably the central engine. Firstly, the luminosities of individual maser features are correlated on time-scales as fine as

We have acquired imaging of the bipolar outflow M2-9 in the transitions [O III] λ5007, H I λ6563, [N II] λ6584, and [S II] λλ6717, 6731. As a result, we are able to map both excitation and density over the face of the nebula. We find that underlying densities in the lobes increase to ne~1.6x103 cm-3 at distances rp~12"-15" from the central star

The recent discovery of dust-correlated diffuse microwave emission has prompted two rival explanations: free-free emission and spinning dust grains. We present new detections of this component at 10 and 15 GHz by the switched-beam Tenerife experiment. The data show a turnover in the spectrum and thereby support the spinning dust hypothesis. We also

We have obtained (in BVRI filters) the structural parameters of four disk galaxies, spanning a range of different morphological types. We believe the parameters are reliable because an extensive part of the galaxies' disks are free from contamination by other components, and a detailed photometric method has been used to derive these quantities
