A spectroscopic analysis of a sample of narrow-line Seyfert 1 galaxies selected from the Sloan Digital Sky Survey
V. Cracco, S. Ciroi, M. Berton +4
We revisited the spectroscopic characteristics of narrow-line Seyfert 1 galaxies (NLS1s) by analysing a homogeneous sample of 296 NLS1s at redshift between 0.028 and 0.345, extract…
V4743 Sgr, a magnetic nova?
P. Zemko, M. Orio, K. Mukai +3
Two XMM Newton observations of Nova V4743 Sgr (Nova Sgr 2002) were performed shortly after it returned to quiescence, 2 and 3.5 years after the explosion. The X-ray light curves re…
Unveiling the parent population of beamed narrow-line Seyfert 1s
M. Berton, L. Foschini, S. Ciroi +11
Narrow-line Seyfert 1 galaxies (NLS1s) are active galactic nuclei (AGN) recently identified as a new class of -ray sources. The high energy emission is explained by the presence…
Broad-band properties of flat-spectrum radio-loud narrow-line Seyfert 1 galaxies
L. Foschini, M. Berton, A. Caccianiga +27
We report about recent updates of broad-band properties of radio-loud narrow-line Seyfert 1 galaxies.
Unveiling the submerged part of the iceberg: radio-loud narrow-line Seyfert 1s with SKA
M. Berton, L. Foschini, A. Caccianiga +7
Narrow-line Seyfert 1 galaxies (NLS1) are active galactic nuclei (AGN) known to have small masses of the central black hole and high accretion rates. NLS1s are generally radio-quie…
Compact steep-spectrum sources as the parent population of flat-spectrum radio-loud NLS1s
Marco Berton, Alessandro Caccianiga, Luigi Foschini +9
Narrow-line Seyfert 1 galaxies (NLS1s) are an interesting subclass of active galactic nuclei (AGN), which tipically does not exhibit any strong radio emission. Seven percent of the…
