In this work we present a multiwavelength study of narrow-line Seyfert 1 galaxies (NLS1s) discovered in the Second Byurakan Survey (SBS). The sample consists of 26 objects, which have $M_{B}\ge -23.0$, or $-19.9 > M_{B} > -23.0$, $0.0243 1$). The traditional linear correlation $L_x$ and $L_{op}$, which seems to hold for AGN in general, is found for SBS NLS1s. An anticorrelation between FWHM of ${H\beta}$ and the ratio of FeII$\lambda4570/H\beta$ is also observed. A weak correlation is found…
Exploring the physics of the accretion and jet in nearby narrow-line Seyfert 1 galaxies
• Physics

In this paper, we explore the physics of the accretion and jet in narrow-line Seyfert 1 galaxies (NLS1). Specifically, we compile a sample composed of 16 nearby NLS1 with $L_{\rm bol}/L_{\rm Edd} The X-ray afterglow of GRB 030329 We report on XMM-Newton and Rossi-XTE observations of the bright (fluence ~10 -4 erg cm -2 ) and nearby ($z=0.1685\$) Gamma-Ray Burst GRB 030329 associated to SN2003dh. The first Rossi-XTE

A Complete Sample of Soft X-Ray-selected AGNs. II. Statistical Analysis*
Direct correlations and a principal component analysis (PCA) are presented for a complete sample of 110 soft X-ray–selected AGNs, of which about half are narrow-line Seyfert 1 galaxies (NLS1's). The

The unified model of Seyfert galaxies suggests that there are hidden broad-line regions (HBLRs) in Seyfert 2 galaxies (S2s). However, there is increasing evidence for the appearance of a subclass of
On-axis spectroscopy of the host galaxies of 20 optically luminous quasars at z ~ 0.3
We present the analysis of a sample of 20 bright low-redshift quasars (M B < - 23 and z < 0.35) observed spectroscopically with the Very Large Telescope (VLT). The Focal Reducer/low dispersion

We present 6 cm Very Large Array observations of the Greene & Ho sample of 19 low-mass active galaxies with high accretion rates. This is one of the only studies of a uniform sample of narrow-line
The Unified Model of Active Galactic Nuclei. II. Evolutionary Connection
We assemble a sample composed of 243 nearby Seyfert galaxies with redshifts z ≤ 0.05 to test the unification scheme. The sample contains 94 broad emission line Seyfert 1 galaxies (BLS1s), 44 narrow
We present the first systematic study of (non-radio-selected) radio-loud narrow-line Seyfert 1 (NLS1) galaxies. Cross-correlation of the Catalogue of Quasars and Active Nuclei with several radio and
A POPULATION OF RADIO-LOUD NARROW-LINE SEYFERT 1 GALAXIES WITH BLAZAR-LIKE PROPERTIES?
Blazars having strong emission lines were found to be associated mostly with broad-line type 1 active galactic nuclei (AGNs). Hitherto, evidence for blazars identified with narrow-line Seyfert 1
