In this paper, we analyze spectra of the Seyfert 1 galaxy NGC 4593 obtained with the Chandra Low Energy Transmission Grating Spectrometer (LETGS), the Reflection Grating Spectrometer (RGS) and the European Photon Imaging Camera's (EPIC) onboard of XMM-Newton. The two observations were separated by7 months. In the LETGS spectrum we detect a highly ionized warm absorber corresponding to an ionization state of 400 10 9 W m, visible as a depression at 10 18 A. This depression is formed by multiple… 

High-energy monitoring of NGC 4593 with XMM–Newton and NuSTAR. X-ray spectral analysis

We present results from a joint XMM–Newton/NuSTAR monitoring of the Seyfert 1 NGC 4593, consisting of 5 × 20 ks simultaneous observations spaced by 2 d, performed in 2015 January. The source is

The X-ray/UV absorber in NGC 4593

We present the results of a recent (March 2011) 160 ks Chandra-LETGS observation of the Seyfert galaxy NGC 4593, and the analysis of archival X-ray and UV spectra taken with XMM-Newton and HST/STIS

The Ionized Nuclear Environment in NGC 985 as seen by Chandra and BeppoSAX

We investigate the ionized environment of the Seyfert 1 galaxy NGC 985 with a new Chandra HETGS observation and an archival BeppoSAX observation. Both spectra exhibit strong residuals to a

An XMM–Newton survey of broad iron lines in Seyfert galaxies

We present an analysis of the X-ray spectra of a sample of 37 observations of 26 Seyfert galaxies observed by XMM–Newton in order to characterize their iron Kα emission. All objects show evidence for

A Galactic Origin for the Local Ionized X-Ray Absorbers

Recent Chandra and XMM-Newton observations of distant quasars have shown strong local (z ~ 0) X-ray absorption lines from highly ionized gas, primarily He-like oxygen. The nature of these X-ray

A soft X-ray study of type I active galactic nuclei observed with Chandra high-energy transmission grating spectrometer

We present the results of a uniform analysis of the soft X-ray spectra of 15 type I active galactic nuclei (AGN) observed with the high-resolution X-ray gratings onboard Chandra. We found that 10 out


We report results from a 2007 Suzaku observation of the Seyfert 1 AGN NGC 4593. The narrow Fe Kα emission line has a FWHM width ∼ 4000 km s−1, indicating emission from ≳ 5000 Rg. There is no evidence

Can a Dusty Warm Absorber Model Reproduce the Soft X-Ray Spectra of MCG –6-30-15 and Markarian 766?

XMM-Newton RGS spectra of MCG -6-30-15 and Mrk 766 exhibit complex discrete structure, which was interpreted in a paper by Branduardi-Raymont and coworkers as evidence for the existence of


Highly ionized, z = 0 metal absorption lines detected in the X-ray spectra of background active galactic nuclei (AGNs) provide an effective method to probe the hot (T ∼ 106 K) gas and its metal



XMM-NEWTON High resolution spectroscopy of NGC 5548

We analyze a 137 ks exposure X-ray spectrum of the Seyfert 1 galaxy NGC 5548 obtained with the XMM-Newton Reflection Grating Spectrometer. Due to the long exposure time, the spectrum is of higher

X-ray spectroscopy of NGC 5548

We analyze the high-resolution X-ray spectrum of the Seyfert 1 galaxy NGC 5548, for the full 0:1{10 keV band, using improved calibration results of the Chandra-LETGS instrument. The warm absorber

ASCA Observations of Seyfert 1 Galaxies. III. The Evidence for Absorption and Emission Due to Photoionized Gas

We present the results from a detailed analysis of the 0.6-10 keV spectra of 23 ASCA observations of 18 objects. We find that in most cases the underlying continuum can be well represented by a power

An X-ray spectral study of 24 type 1 active galactic nuclei

I present a study of the X-ray spectral properties of a sample containing 24 type-1 active galactic nuclei using the medium spectral resolution of ``ASCA''. The sample consists of 20 radio-quiet

A 10-day ASCA observation of the narrow-line Seyfert 1 galaxy IRAS 13224-3809

We present an analysis of a 10-day continuous ASCA observation of the narrow-line Seyfert 1 galaxy IRAS 13224- 3809. The total band (0:7 10 keV) light curve binned with 500 s reveals trough-to-peak

Accurate galactic N(H) values towards quasars and AGN

Integrated Galactic 21-cm column densities toward about 174 quasars and AGN are presented. The data are corrected for stray radiation, using the technique of Lockman et al. (1986). Because of the
