X - ray reflection in the nearby Seyfert 2 galaxy NGC 1068
We use the full broad-band XMM-Newton EPIC data to examine the X-ray spectrum of the nearby Seyfert 2 galaxy NGC 1068, previously shown to be complex with the X-ray continuum being a sum of components reflected/scattered from cold (neutral) and warm (ionised) matter, together with associated emission line spectra. We quantify the neutral and ionised reflectors in terms of the luminosity of the ...

1 Based on observations carried out with the IRAM Plateau de Bure Interferometer. IRAM is supported by INSU/CNRS (France), MPG (Germany) and IGN (Spain). – 2 – ABSTRACT Sub-arcsecond IRAM Plateau de Bure mm-interferometric observations of the 12 CO (2-1) line emission in the Seyfert 1 NGC 3227 and the Seyfert 2 NGC 1068 have revealed complex kinematic systems in the inner 100 pc to 300 pc that ...
متن کاملThe Molecular Gas in the Circumnuclear Region of Seyfert Galaxies1
Sub-arcsecond IRAM Plateau de Bure mm-interferometric observations of the CO (2-1) line emission in the Seyfert 1 NGC 3227 and the Seyfert 2 NGC 1068 have revealed complex kinematic systems in the inner 100 pc to 300 pc that are not consistent with pure circular motion in the host galaxies. Modeling of these kinematic systems with elliptical orbits in the plane of the host galaxy (representing ...
متن کاملEmission Lines in a Nearby Seyfert Galaxy NGC 1068 Observed with OAO / ISLE
We present J -band long-slit spectroscopic observation of NGC 1068 classified as a Seyfert 2 galaxy. J -band observations with OAO/ISLE provide clear detection of spatially extended [Fe II] 1.257 m and [P II] 1.188 m lines. We found that [Fe II] 1.257 m=[P II] 1.188 m increases with distance from a central continuum peak. Observed line ratios around the nucleus (continuum peak) are consistent w...
متن کاملKinematics and morphology of the narrow - line region in the Seyfert galaxy NGC 1386 ?
We present a high spatial and spectral resolution 2-D echelle spectrogram of the Narrow–Line Region in the Seyfert 2 galaxy NGC1386. This Seyfert galaxy was observed with CASPEC in the wavelength range 5270– 7725 Å which covers the Hα and the [N ii] lines. With the use of spatially high resolved images taken with the WFPC2 aboard the Hubble Space Telescope we could identify individual component...
