XMM-Newton observations of SDSS J143030.22−001115.1: an unusually flat spectrum AGN

چکیده

We present XMM-Newton observations of the AGN SDSS 1430-0011. The low S/N spectrum of this source obtained in a snap shot Chandra observation showed an unusually flat continuum. With the follow up XMM-Newton observations we find that the source spectrum is complex; it either has an ionized absorber or a partially covering absorber. The underlying power-law is in the normal range observed for AGNs. The low luminosity of the source during Chandra observations can be understood in terms of variations in the absorber properties. The X-ray and optical properties of this source are such that it cannot be securely classified as either a narrow line Seyfert 1 or a broad line Seyfert 1 galaxy.

SDSS J 143030 . 22 - 001115 . 1 : A misclassified narrow - line Seyfert 1 galaxy with flat X - ray spectrum

We used multi-component profiles to model Hβ and [O III]λλ4959,5007 lines for SDSS J143030.22-001115.1, a narrow-line Seyfert 1 galaxy (NLS1) in a sample of 150 NLS1s candidates selected from the Sloan Digital Sky Survey (SDSS) Early Data Release (EDR). After subtracting the Hβ contribution from narrow line regions (NLRs), we found that its full width half maximum (FWHM) of broad Hβ line is nea...

X-ray Bright Optically Inactive Galaxies in XMM-Newton/SDSS fields: more diluted than absorbed?

We explore the properties of X-ray Bright Optically Inactive Galaxies (XBONG) detected in the 0.5-8 keV spectral band in 20 public XMM-Newton fields overlapping with the SDSS. We constrain our sample to optically extended systems with log fX/fopt > −2 that have spectroscopic identifications available from the SDSS (r < 19.2mag). The resulting sample contains 12 objects with LX(0.5−8 keV) = 5×10...

We present Chandra and XMM-Newton observations of the composite star-forming/Seyfert galaxy IRAS20051-1117. The X-ray imaging and spectral properties reveal the presence of an active nucleus. The Chandra image shows a strong nuclear point source (L(2 − 10keV) ∼ 4 × 10 42 erg s −1). The nuclear X-ray source coincides with a bright, also un-resolved, UV source which appears in the XMM-Newton Opti...

ASTRONOMY AND ASTROPHYSICS The first XMM-Newton spectrum of a high redshift quasar

Your thesaurus codes are: missing; you have not inserted them ASTRONOMY AND ASTROPHYSICS The first XMM-Newton spectrum of a high redshift quasar-PKS 0537−286. Abstract. We present XMM-Newton observations of the high redshift (z = 3.104), radio-loud quasar PKS 0537−286. The EPIC CCD cameras provide the highest signal-to-noise spectrum of a high-z quasar to date. The EPIC observations show that P...

XMM-Newton observations of two hyperluminous IRAS galaxies: Compton-thick quasars with obscuring starbursts

We present XMM-Newton observations of two hyperluminous IRAS galaxies (LBol > 10h 50 L⊙), neither of which was previously detected by ROSAT. Published models of the infrared spectral energy distributions imply that a starburst and obscured quasar contribute equally to the power of each source. IRAS F12514+1027 (z = 0.30) is detected in 18.6 ks with 130 EPIC-pn counts over 0.2-12 keV. The soft X...
