Revealing the Broad Line Region of NGC 1275: The Relationship to Jet
  Power
  NGC 1275 is one of the most conspicuous active galactic nuclei (AGN) in the
local Universe. The radio jet currently emits a flux density of $\sim 10$ Jy at
$\sim 1$ mm wavelengths, down from the historic high of $\sim 65$ Jy in 1980.
Yet, the nature of the AGN in NGC 1275 is still controversial. It has been
debated whether this is a broad emission line (BEL) Seyfert galaxy, an obscured
Seyfert galaxy, a narrow line radio galaxy or a BL-Lac object. We clearly
demonstrate a persistent H$\beta$ BEL over the last 35 years with a full width
half maximum (FWHM) of 4150 - 6000 km/s. We also find a prominent P$\alpha$ BEL
(FWHM $\approx 4770 $ km/s) and a weak CIV BEL (FWHM $\approx 4000 $ km/s),
H$\beta$/CIV $\approx 2$. A far UV HST observation during suppressed jet
activity reveals a low luminosity continuum. The H$\beta$ BEL luminosity is
typical of broad line Seyfert galaxies with similar far UV luminosity. X-ray
observations indicate a softer ionizing continuum than expected for a broad
line Seyfert galaxy with similar far UV luminosity. This is opposite of the
expectation of advection dominated accretion. The AGN continuum appears to be
thermal emission from a low luminosity, optically thick, accretion flow with a
low Eddington ratio, $\sim 0.0001$. The soft, weak ionizing continuum is
consistent with the relatively weak CIV BEL. Evidence that the BEL luminosity
is correlated with the jet mm wave luminosity is presented. Apparently, the
accretion rate regulates jet power.
