JournalThe extended emission line region of the Seyfert galaxy
We present the results of observations of the extended emission-line region of the Seyfert 2 galaxy Mrk 573, obtained using the WFPC2 camera on board HST and the TIGER integral eld spectrograph on the Canada France Hawaii Telescope. The WFPC2 observations consist of a set of narrow-band linear ramp lter images in the O iii]5007 and H + N ii]6583 lines, as well as continuum and other emission-li...
متن کاملXmm–newton Observation of the Seyfert 2 Galaxy Ngc4138
The XMM–Newton data presented here are the first X–ray observation of the Seyfert 2 galaxy NGC4138. Although the galaxy has been pointed by ROSAT– HRI, it was not detected, with a flux upper limit of about 1.1×10−13 erg cm−2 s−1 in the 0.2−2.4 keV energy band1. XMM–Newton performed the observation on 26 November 2001. The source is detected for the first time in X–rays with F0.2−2.4 = 1.0 × 10−...
متن کاملVariability Characteristics of the Seyfert 1 Galaxy Ngc 3783
We have characterized the energy-dependent X-ray variability properties of the Seyfert 1 galaxy NGC 3783 using archival XMM-Newton and Rossi X-ray Timing Explorer data. The high-frequency fluctuation power spectral density function (PSD) slope is consistent with flattening towards higher energies. Light curve cross correlation functions yield no significant lags, but peak coefficients generally...
متن کاملDynamics of the Narrow - Line Region in the Seyfert 2 Galaxy Ngc
We present dynamical models based on a study of high-resolution long-slit spectra of the narrow-line region (NLR) in NGC 1068 obtained with the Space Telescope Imaging Spectrograph (STIS) aboard The Hubble Space Telescope (HST). The dynamical models consider the radiative force due to the active galactic nucleus (AGN), gravitational forces from the supermassive black hole (SMBH), nuclear stella...
متن کاملMolecular Gas in the Double - Barred Seyfert 2 Galaxy
We present CO(1-0) and CO(2-1) maps of the Seyfert galaxy NGC 5728. Although a stellar nuclear bar structure is clearly identified in the near-infrared images in the central 10 " , inside the ring identified as the ILR of the primary bar, there is no nuclear bar structure in the molecular gas. Instead, the CO emission reveals an elongated structure, 15 " in length, beginning at the nucleus (def...
