Chandra 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 کاملAtomic and molecular gas in the merger galaxy NGC 1316 ( Fornax A ) and its environment
We present and interpret observations of atomic and molecular gas toward the southern elliptical galaxy NGC 1316 (Fornax A), a strong double-lobe radio source with a disturbed optical morphology that includes numerous shells and loops. The CO(1–0), CO(2–1), and Hi observations were made with SEST and the VLA. CO emission corresponding to a total molecular hydrogen mass of ∼5×10 M⊙ was detected ...
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 کاملThe stellar dynamics and mass of NGC 1316 using the radial velocities of Planetary Nebulae
We present a study of the kinematics of the outer regions of the early-type galaxy NGC 1316, based on radial velocity measurements of 43 planetary nebulae as well as deep integrated-light absorption line spectra. The smoothed velocity field of NGC 1316 indicates fast rotation at a distance of 16 kpc, possibly associated with an elongated feature orthogonal to the inner dust lanes. The mean squa...
