The Fundamental Plane of Black Hole Activity in the Optical Band

Understand

Black hole accretion and jet formation have long been thought to be scale invariant.

• One empirical relation suggesting scale invariance is the Fundamental Plane of Black Hole activity, which is a plane in the space given by black hole mass and the radio/X-ray luminosities.
• We search for an alternative version of this plane using the luminosity of [OIII] emission line instead of X-ray luminosity.
• We use a complete sample of 39 supermassive black holes selected from the Palomar Spectroscopic Survey with available radio and optical measurements and information on black hole mass.
