NGC 6946: kinematics of the starburst in the circum-nuclear zone.
Using spectroscopic observations at relatively high resolution (Δλ ≡ 0.35 Å) in the region within 30 arcseconds of the nucleus of NGC 6946 the authors have...
Observations of the Seyfert galaxy NGC 985 have revealed large-scale extended ionized zones, covering a large fraction of the ring-shaped structure of this...
NGC2346 - Visible and Infrared Observations of Several Mass-Loss Episodes
New observations of the eclipses of the central star of NGC 2346 are presented; these, together with other data available in the literature allow the authors to...
The first results of HST NICMOS observations of BL Lacertae objects are presented. Selected target, observed through the F160W filter, are from the HST...
We have obtained HST WFPC2 and NICMOS observations in the nuclear region of the closest powerful active galaxy known, NGC 5128 (Centaurus A). Narrow band...
