WISE2MBH: A scaling-based algorithm for probing supermassive black hole masses through WISE catalogues

Understand

Supermassive Black Holes (SMBHs) are commonly found at the centers of massive galaxies.

• Estimating their masses ($M_\text{BH}$) is crucial for understanding galaxy-SMBH co-evolution.
• We present WISE2MBH, an efficient algorithm that uses cataloged Wide-field Infrared Survey Explorer (WISE) magnitudes to estimate total stellar mass ($M_*$) and scale this to bulge mass ($M_\text{Bulge}$), and $M_\text{BH}$, estimating the morphological type ($T_\text{Type}$) and bulge fraction ($B/T$) in the process.
• WISE2MBH uses scaling relations from the literature or developed in this work, providing a streamlined approach to derive these parameters.
