  • Blazars and Seyfert galaxies accretion rates

    Accretion rates and their correlation with cosmological redshifts for a sample of blazars and Seyfert galaxies are presented. The sample includes 77 blazars (28 FSRQs, 26 LBLs,...
  • Chemical abundances of Seyfert 2 AGNs IV

    We build detailed composite models of photoionization and shock ionization based on the SUMA code to reproduce emission lines emitted from the Narrow Line Regions (NLR) of...
  • 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...
  • Reverberation mapping for Mrk 817 and NGC 7469

    We present the results from a spectroscopic monitoring campaign to obtain reverberation mapping measurements and investigate the broad-line region (BLR) kinematics for active...
  • Chandra X-ray sources of NGC 1068

    We present an analysis of the compact X-ray source population in the Seyfert 2 galaxy NGC 1068, imaged with a 50ks Chandra observation. We find a total of 84 compact sources on...
  • AGN in the KISS-RASS sample

    We present a study of the X-ray properties of a volume-limited sample of optically selected emission-line galaxies. The sample is derived from a correlation between the KPNO...
  • Narrow-line Seyfert 1 galaxies from SDSS EDR

    We present a sample of 150 narrow-line Seyfert 1 galaxies (NLS1's) found within the Sloan Digital Sky Survey (SDSS) Early Data Release (EDR) (Stoughton et al.,...
  • NGC 6221 ionized gas kinematics

    Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (PA =5{deg}, 50{deg}, 95{deg},...
  • Circinus galaxy N-band VLTI/MATISSE images

    Active galactic nuclei play a key role in the evolution of galaxies, but their inner workings and physical connection to the host are poorly understood due to a lack of angular...
  • Molecular gas prop. in local Seyfert 2 gal.

    We present a multiwavelength study of the molecular gas properties of a sample of local Seyfert 2 galaxies to assess if, and to what extent, the presence of an active galactic...
  • HST/COS and FUSE UV spectra of Mrk 509

    To elucidate the location, physical conditions, mass outflow rate, and kinetic luminosity of the outflow from the active nucleus of the Seyfert 1 galaxy Mrk 509 we used...
  • The XMM-ATLAS catalogues

    Wide area X-ray and far infrared surveys are a fundamental tool to investigate the link between AGN growth and star formation, especially in the low-redshift universe (z<1)....
  • Low-luminosity type-1 QSO sample

    Recognizing the properties of the host galaxies of quasi-stellar objects (QSOs) is essential to understand the suspected coevolution of central supermassive black holes (BHs)...
  • NIR long-slit spectra of Seyfert galaxies

    The excitation of the gas phase of the interstellar medium can be driven by various mechanisms. In galaxies with an active nucleus, such as Seyfert galaxies, both radiative and...
  • The Hamburg/SAO Survey for ELGs. V.

    We present the fifth list with results of the Hamburg/SAO Survey for Emission-Line Galaxies (HSS therein, SAO - Special Astrophysical Observatory, Russia). The list is a result...
  • 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...
  • Universidad Complutense de Madrid list 1

    A low dispersion objective-prism survey for low-redshift emission-line galaxies (ELGs) is being carried out by the University Complutense de Madrid with the Schmidt telescope at...
