This work studies the optical emission line properties of a sample of 155 low-redshift bright X-ray-selected ROSAT Seyfert 1-type active galactic nuclei for which adequate...

HIGH-REDSHIFT NARROW LINE SEYFERT 1 GALAXIES: A CANDIDATE SAMPLE

活动星系核光谱与光度

高红移星系候选体识别

The study of Narrow line Seyfert 1 galaxies (NLS1s) is now mostly limited to low redshift (z < 0.8). This is because their definition requires the presence of the Hβ emission line, which is red-shifte

活动星系核光谱与光度

低电离核发射区

We present a compilation of spectral energy distributions (SEDs) of 35 weak active galactic nuclei (AGNs) in low-ionization nuclear emission regions (LINERs) using recent data...

An Atlas of Recalibrated HST FOS Spectra of Active Galactic Nuclei and Quasars ("FOS_AGN")

活动星系核光谱与光度

光谱仪校准

The FOS_AGN atlas provides spectral FITS data and preview files for all successful pre-COSTAR spectra using the Faint Object Spectrograph of AGNs (Active Galactic Nuclei). A discussion of the uniform
