We present 0.35-2.5 ЮМm spectra of the south and northwest filaments in the reflection nebula NGC 7023. ... Our spectra fail to show their predicted second emission band at 1.0 ЮМm even though both filaments exhibit strong emission in the familiar 0.7 ЮМm ERE band. The northwest filament spectrum does show one, and possibly two, new dust emission features in the near-infrared. We clearly detect a strong emission band at 1.5 ЮМm which we tentatively attribute to ЮВ-FeSi2 grains. ...

... Version 2.0 of the CFITSIO subroutine interface for reading and writing FITS format data files is now available from the HEASARC web site. Some of the major new features in this version are the ability to read FITS files over the network, support for reading IRAF format images, and options for filtering the input file at run time. CFITSIO is a software library that contains both C and Fortran-callable interface routines for reading and writing data files in FITS format. ...

We present broadband photometry in the optical, near infrared and sub-millimetre, and mid-infrared spectrophotometry of a selection of carbon stars with optically thin envelopes. ... Beside the emission features at 11.3 \mu m due to silicon carbide grains in the circumstellar environment, many of our mid-infrared spectra show an emission feature at 8.6 \mu m. All the observed spectral energy distributions exhibit a very large far-infrared flux excess. ...

Giant radio galaxies constitute a class of radio sources with linear sizes on the megaparsec scale (Saripalli 1988). ... The Westerbork Northern Sky Survey (WENSS) has discovered several cases of "inner-double" or "double-double" giant radio galaxies: the findings suggest that such structures predominantly occur among the larger of radio galaxies. ... Close to the core of B0114-476, a narrow jet-like feature is seen directed toward the southern inner lobe which also has the brighter hotspots. ...

... We detect three main diffuse components: the Virgo ICM at ~2.4 keV, the extended halo of M86 at ~1.2 keV, and the cooler central and stripped gas of M86 at ~0.8 keV. The most striking feature is a long tail of emission, which consists of a plume ~ 4' north of M86 and two main extensions emanating from the plume. ... Ram pressure stripping from an aspherical potential can also explain the split "double tails" seen in M86 and in other Virgo cluster galaxies in the field. ...

. Comment on J0405+3803 . Our image contains a feature of 25 mJy at 14 mas E-NE from the brightest component. It is not visible in the Caltech-Jodrell (CJ) survey image at 5 GHz (Xu et al. 1995) obtained about 6 years earlier. The 1.6 GHz CJ image (Polatidis et al. 1995) does show an extended feature close to the position in question, but somewhat displaced toward west. VLBApls home page . Last modified: 16 Oct 2000
