Spectropolarimetry of active galaxy 3C 390.3
Here we present the spectropolarimetric observations of the radio-loud active galaxy 3C 390.3 in the period 2009-2014 (24 epochs). The galaxy has been observed with the 6-m... -
Spectral parameters for Mrk 335 and Ark 564
We present a comprehensive flux-resolved spectral analysis of the bright narrow-line Seyfert 1 AGNs, Mrk 335 and Ark 564 using observations by XMM-Newton satellite. The mean and... -
X-ray sources in the AKARI NEP deep field
We present data products from the 300ks Chandra survey in the AKARI North Ecliptic Pole (NEP) deep field. This field has a unique set of 9-band infrared photometry covering 2-24... -
Subarcsecond mid-infrared atlas of local AGN
We present the first subarcsecond-resolution mid-infrared (MIR) atlas of local active galactic nuclei (AGN). Our atlas contains 253 AGN with a median redshift of z=0.016, and... -
PKS 0558-504 UVOT and XRT monitoring
PKS 0558-504 is a highly-variable, X-ray-bright, radio-loud, narrow-line Seyfert 1 galaxy with super-Eddington accretion rate and extended jets that do not dominate the emission... -
Type 1 AGN at low z. III.
We present the optical narrow-line ratios in a Sloan Digital Sky Survey (SDSS) based sample of 3175 broad H{alpha} selected type 1 active galactic nuclei (AGN), and explore... -
Mrk 6 H{alpha}, H{beta} and H{gamma} spectra
We present the results of optical spectral and photometric observations of the nucleus of Markarian 6 made with the 2.6-m Shajn telescope at the Crimean Astrophysical... -
FeK lines in Seyfert 1 galaxies
We construct full broad-band models in an analysis of Suzaku observations of nearby Seyfert 1 active galactic nuclei (AGN) (z<=0.2) with exposures >50ks and with greater... -
Emission-line properties of Seyfert 2 nuclei
This is the third paper of a series devoted to the study of the global properties of Joguet's sample (2001A&A...380...19J) of 79 nearby galaxies observable from the southern... -
Radio galaxies in the 2dFGRS
We use redshift determinations and spectral analysis of galaxies in the 2dF Galaxy Redshift Survey () to study the properties of local radio sources with S>=1mJy. 557 objects... -
