Observations of Interacting Galaxy Pair NGC 4038 / 9
We present the results of new radio interferometer H i line observations for the merging galaxy pair NGC 4038/9 (‘The Antennae’), obtained using the Australia Telescope Compact Array. The results improve substantially on those of van der Hulst (1979) and show in detail the two merging galactic disks and the two tidal tails produced by their interaction. The small edge-on spiral dwarf galaxy ESO...
متن کاملMultifrequency observations of the jets in the radio galaxy NGC 315
We present images of the jets in the nearby radio galaxy NGC 315 made with the VLA at five frequencies between 1.365 and 5 GHz with resolutions between 1.5 and 45 arcsec FWHM. Within 15 arcsec of the nucleus, the spectral index of the jets is α = 0.61. Further from the nucleus, the spectrum is flatter, with significant transverse structure. Between 15 and 70 arcsec from the nucleus, the spectra...
متن کاملNewton observations of the interacting galaxy pairs NGC 7771 / 0 and NGC 2342 / 1
We present XMM-Newton X-ray observations of the interacting galaxy pairs NGC 7771/7770 & NGC 2342/2341. In NGC 7771, for the first time we are able to resolve the X-ray emission into a bright central source (L X ∼ 10 41 erg s −1), plus two bright (L X > 10 40 erg s −1) ultraluminous X-ray sources (ULXs) located either end of the bar. The soft emission of the central source is well-modelled by a...
متن کاملObservations of the starburst galaxy NGC 2146
NGC 2146 is a peculiar spiral galaxy which is currently undergoing a major burst of star formation and is immersed in a extended H I structure that has morphological and kinematical resemblence to a strong tidal interaction. This paper reports aperture synthesis observations carried out in the 21cm line with the Very Large Array (VLA) of two fields positioned to optimally cover the H I streams ...
متن کاملGalex Uv Observations of the Interacting Galaxy Ngc 4438 in the Virgo Cluster
We present GALEX NUV (2310Å) and FUV (1530Å) images of the interacting galaxy NGC 4438 (Arp 120) in the center of the Virgo cluster. These images show an extended (20 kpc) tidal tail at the north-west edge of the galaxy previously undetected at other wavelengths, at 15-25 kpc from its nucleus. Except in the nucleus, the UV morphology of NGC 4438 is totally different from the Hα+[NII] one, more ...
