| Abstract: |
We present a supermassive black hole (SMBH) mass measurement in the nearby type-1 Seyfert galaxy NGC 1097 using ALMA observations of dense gas kinematics traced with HCN (J=1–0) emission line. Assuming a host galaxy inclination of 46°, we derive a SMBH mass, MBH=1.40+0.27–0.32×108M☉, and an I-band mass to light ratio to be 5.14+0.03–0.04. The measured SMBH mass is in good agreement with the SMBH mass and bulge velocity dispersion relationship. Our result showcases ALMA's potential for deriving accurate SMBH masses in larger number of samples, that will further elucidate the relationship between the black hole and host galaxy properties to constrain the coevolutionary growth of galaxies and black holes. |
