Horizons: Exploring the Universe
But spectra of Seyfert galaxy nuclei contain broad emission lines. Emission lines
are produced by a hot, low-density gas, so the gas in the nuclei of Seyfert
galaxies must be highly excited. The width of the spectral lines suggests large
Doppler ...

An Introduction to Active Galactic Nuclei
A Seyfert galaxy has a quasar-like nucleus, but the host galaxy is clearly
detectable. The original definition of the class (Seyfert 1943) was primarily
morphological, i.e., these are galaxies with high surface brightness nuclei, and
subsequent ...

It appears as though MCG —3-34-64 is the type 1.8 Seyfert galaxy, while the
source named in the accepted proposal, MCG —3-34-63 is not. The separation
between the to is less than 1.8 arcmin. However, the observations of this source
do ...

Mass-Transfer Induced Activity in Galaxies
However, the recent literature on the prevalence of Seyfert galaxy companions, is
confusing and somewhat contradictory. To clarify this we have constructed a
statistical profile of Seyfert galaxy companions in the CfA ZCAT. We use a
random ...

Ark 539 (top row) is a Seyfert galaxy that does not appear to be disturbed in the
optical. In HI, however, a tidal bridge can be seen connecting the southern part of
the Seyfert galaxy to a companion galaxy (at the same redshift) to the south-east.
