Abstract: Interferometric observations in the mid-infrared made studies of the central dusty tori of Active Galactic Nuclei (AGNs) possible and proved their existence in a number of nearby AGNs. Our first results on Centaurus A (NGC 5128) showed that nuclear dust also exists in the innermost parsec of this galaxy (Meisenheimer et al. ... Its minor axis is oriented almost perfectly parallel to the radio jet. ...

We investigate models for main-sequence and horizontal-branch (HB) stars constructed using the Carson opacities and make comparisons with models based on the Cox-Stewart opacities. ... The drop in the hydrogen-shell luminosity due to the helium-core expansion during HB evolution is greater than that obtained with the Cox-Stewart opacities. ... Studies of main-sequence (MS) stars lead to agreement with Stothers' (1974a,b, 1976) results for homogeneous models constructed with Carson opacities. ...

... AAS link ] . ... Our internal perspective makes it difficult to determine the spiral structure of our own galaxy. ... H I absorption, on the other hand, traces colder, denser gas that should be more confined in discrete clouds and perhaps discrete spiral arms. In addition, H I self-absorption (HISA) requires background H I emission at the same velocity as the foreground absorbing gas, thus introducing a much-needed constraint on the large-scale sightline geometry and kinematics. ...

We report the density structure of the ultracompact HII regions G35.20-1.74, G9.62+0.19-E, and G75.78+0.34-H2O. The density profiles are derived from radio continuum emission at wavelengths from 6 to 0.3cm. In the case of G35.20-1.74, a cometary UC HII region with a core and a tail, the spectrum of the core varies as Snu~nu^(0.6), implying that the density structure is ne~r^(-2). ...
