A Reeection Dominated X{ray Spectrum Discovered by Asca in the Circinus Galaxy
نویسندگان
چکیده
We report the rst pointed X{ray observation, made by ASCA, of the nearby Seyfert 2 galaxy in Circinus. The spectrum consists of a very prominent (EW2 keV) uorescent 6.4 keV iron line, a very at continuum (photon spectral index less than one) and other lines, including one at 7 keV probably due, at least in part, to iron K uorescent emission. The spectrum is consistent with Compton scattering and uorescent emission from cold matter illuminated by an obscured active nucleus.

The Physical Conditions of the X-ray Emission Line Regions in the Circinus Galaxy
We present a detailed X-ray spectral analysis of the Circinus Galaxy using archival data obtained with the ASCA satellite. The spectrum shows numerous emission lines in the soft X-ray band from highly ionized ions, as well as Compton reflection and fluorescent lines from neutral or near-neutral matter. We analyze the spectrum in the context of a self-consistent recombination cascade model and f...
متن کاملX-RAY IMAGING OF THE SEYFERT 2 GALAXY CIRCINUS WITH Chandra
We present results from the zeroth-order imaging of a Chandra HETGS observation of the nearby Seyfert 2 galaxy Circinus. Twelve X-ray sources were detected in the ACIS-S image of the galaxy, embedded in diffuse X-ray emission. The latter shows a prominent (∼ 18) soft “plume” in the N-W direction, coincident with the [O III] ionization cone. The radial profiles of the brightest X-ray source at v...
متن کاملSuzaku Observations of the Circinus Galaxy
We report Suzaku observations of the active, Compton-thick Circinus galaxy. Observations were obtained with both the X-ray Imaging spectrometer (XIS) and the Hard X-ray Detector (HXD). Below 10 keV, the nuclear spectrum is dominated by radiation reflected from cold dense gas of high column density, while above 13 keV the radiation is directly transmitted nuclear emission seen through a column d...
متن کاملChandra Observations of Ngc 4698: a Seyfert 2 Galaxy with No Absorption
We present Chandra ACIS-S observations of the enigmatic Seyfert 2 galaxy NGC 4698. This object, together with several other bona fide Seyfert 2 galaxies, shows no absorption in the low spatial resolution ASCA data, in contrast to the standard unification models. Our Chandra observations of NGC 4698 probe directly the nucleus, allowing us to check whether nearby sources contaminate the ASCA spec...
متن کاملASCA observations of the iron K complex of Circinus X-1 near zero phase: spectral evidence for partial covering
We report on ASCA energy spectra of Cir X-1 taken near its zero phase on 1994 August 4–5. The ASCA SIS detectors allow a much more detailed study of the iron K complex than has been possible before. We find that prior to a sudden upward flux transition the dominant iron K feature appears to consist of a large edge from neutral or nearly-neutral iron. The depth of the edge corresponds to an abso...
