Enormous disc of cool gas surrounding the nearby powerful radio galaxy NGC 612 ( PKS 0131 - 36 )
We present the detection of an enormous disc of cool neutral hydrogen (H I) gas surrounding the S0 galaxy NGC 612, which hosts one of the nearest powerful radio sources (PKS 0131-36). Using the Australia Telescope Compact Array, we detect MHI = 1.8 × 10 9M⊙ of H I emission-line gas that is distributed in a 140 kpc wide disc-like structure along the optical disc and dust-lane of NGC 612. The bul...
متن کاملChandra X - ray Observations of NGC 1316 ( Fornax A )
2 Abstract We report the results of the Chandra ACIS sub-arcsecond resolution X-ray observation of the archetypal merger radio galaxy NGC 1316 (Fornax A). We confirm the presence of fine sub-structures in the hot Interstellar Medium (ISM). Some of these are likely to result from interaction with the radio jets, while others may be related to a complex intermingling of different phases of the IS...
متن کاملTelescope Planetary Camera Images of NGC 1316 ( Fornax A ) 1
We present HST Planetary Camera V and I band images of the central region of the peculiar giant elliptical galaxy NGC 1316. These high resolution Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by AURA, Inc., under NASA Contract No. NAS 5-26555. The National Optical Astronomy Observatories are operated by the A...
متن کاملMeasurements of the Field and Particle Energy Distributions in the West Lobe of the Radio Galaxy NGC 1316 ( Fornax A )
A follow-up X-ray study was made of the west lobe of the radio galaxy Fornax A, (NGC 1316) based on new ASCA observations made in 1997 for 98 ks, and incorporating the previous observation in 1994 for 39 ks. The 0.7–10 keV spectrum of the emission can be described by a power-law of energy index 0.74 ± 0.10, which agrees with the synchrotron radio index of 0.9 ± 0.2. Therefore, the X-rays are re...
متن کاملMid-infrared Irs Spectroscopy of Ngc 7331: a First Look at the Spitzer Infrared Nearby Galaxies Survey (sings) Legacy
The nearby spiral galaxy NGC 7331 was spectrally mapped from 5 to 38 m using all modules of Spitzer’s Infrared Spectrograph (IRS). A strong new dust emission feature, presumed due to polycyclic aromatic hydrocarbons, was discovered at 17.1 m. The feature’s intensity is nearly half that of the ubiquitous 11.3 m band. The 7–14 m spectral maps revealed significant variation in the 7.7 and 11.3 m P...
