TL;DR

This paper establishes a new fundamental plane relation for supermassive black holes in elliptical galaxies, linking black hole mass with galaxy photometric properties, improving mass estimates and revealing a strong connection between black hole growth and galaxy structure.

Contribution

It introduces a novel fundamental plane for supermassive black holes that enhances mass prediction accuracy and deepens understanding of black hole-galaxy co-evolution.

Findings

Tightly distributed black hole masses around the new plane.

Improved residuals over traditional $ ext{M}_ ext{BH}- ext{sigma}$ and $ ext{M}_ ext{BH}-L$ relations.

Strong multidimensional link between black hole formation and galaxy photometry.

Abstract

We obtain the coefficients of a new fundamental plane for supermassive black holes at the centers of elliptical galaxies, involving measured central black hole mass and photometric parameters which define the light distribution. The galaxies are tightly distributed around this mass fundamental plane, with improvement in the rms residual over those obtained from the $\mbh-\sigma$ and $\mbh-L$ relations. This implies a strong multidimensional link between the central massive black hole formation and global photometric properties of elliptical galaxies and provides an improved estimate of black hole mass from galaxy data.
