Narrowband images of 51 symbiotic stars were obtained at the ESO and ORM observatories to search for resolved optical nebulae. Ionized nebulae much larger than previously known are found around CH Cyg, HM Sge and V1016 Cyg, and they will be discussed in detail in forthcoming papers. A nebula with a deconvolved size between 0farcs9 and 1farcs5 is

We present two-dimensional optical spectroscopy of the central region (9.4"x12.2") of the Seyfert 1 ring galaxy NGC 985 obtained with an optical fiber system (two-dimensional Fiber ISIS System). The 95 spectra presented here include the Hβ-[O III] lambdalambda4959, 5007 emission lines and the Mg I b absorption lines, which permit the study of the

We imaged the X-ray error box of GRB 980703, beginning 22.5 hr after the gamma-ray event, in both the optical R and near-infrared H bands. A fading optical/IR object was detected within the X-ray error box, coincident with the variable radio source reported by Frail et al. in 1998, who also detected the optical transient independently of us

We present a study of the trends in luminosity, linear size, spectral index, and redshift of classical double radio sources, from three complete samples selected at successively fainter low radio-frequency flux limits. We have been able to decouple the effects of the tight correlation between redshift and luminosity (inherent in any single flux

Four planetary nebulae (PNe) with conspicuous point-symmetric morphology are studied in this paper through high-quality imagery and long-slit echelle spectroscopy. Point symmetry is also found in the velocity space, and this is related to particular forms of bipolar collimated outflows. Morphology and kinematics together reveal the presence of
