A view of the narrow-line region in the infrared: active galactic nuclei with resolved fine-structure lines in the Spitzer archive
narrow-line region infrared: active galactic nuclei resolved fine-structure lines
2011/10/10
We queried the Spitzer archive for high-resolution observations with the Infrared Spectrograph of optically selected active galactic nuclei (AGN) for the purpose of identifying sources with resolved f...
The relation of optical/UV and X-ray emission in low-luminosity active galactic nuclei
relation optical/UV X-ray emission low-luminosity active galactic nuclei
2011/10/9
We study the relation of optical/UV and X-ray emission in the low luminosity active galactic nuclei (LLAGNs), using a sample of 49 sources including 28 local Seyfert galaxies and 21 low-ionization nuc...
Fermi Large Area Telescope Observations of the Active Galaxy 4C +55.17: Steady, Hard Gamma-Ray Emission and its Implications
Steady Hard Gamma-Ray Emission Implications
2011/9/29
We report Fermi/LAT observations and broad-band spectral modeling of the radio-loud active galaxy 4C +55.17 (z=0.896), formally classified as a flat-spectrum radio quasar. Using 19 months of all-sky s...
Near-Infrared Reverberation by Dusty Clumpy Tori in Active Galactic Nuclei
Near-Infrared Reverberation Dusty Clumpy Active Galactic Nuclei
2011/9/27
According to recent models, the accretion disk and black hole in active galactic nuclei are surrounded by a clumpy torus. We investigate the NIR flux variation of the torus in response to a UV flash f...

Hard X-ray Spectrum of Mkn 421 during the Active Phase
X-rays BL Lac sources massive black hole candidates jet emission individual—Mkn 421
2009/5/20
Spectral measurement of Mkn 421 were made in the hard Xray
energy band of 20–200 keV using a high sensitivity, large area scintillation
counter telescope on November 21, 2000 and these coincided wit...
Photometric Variability of Four Coronally Active Stars
Stars variable optical photometry X-rays source
2009/5/19
We present photometric observations of four stars that are
optical counterparts of soft X-ray/EUV sources, namely 1ES 0829+15.9,
1ES0920-13.6, 2RE J110159+223509 and 1ES 1737+61.2. We have discovere...
