The CO Tully-Fisher Relation and Implications for the Host Galaxies of High-Redshift Quasars
Luis C. Ho
The integrated line width derived from CO spectroscopy provides a powerful tool to study the internal kinematics of extragalactic objects, including quasars at high redshift, provi…
A New Sample of Low-mass Black Holes in Active Galaxies
Jenny E. Greene, Luis C. Ho
We present an expanded sample of low-mass black holes (BHs) found in galactic nuclei. Using standard virial mass techniques to estimate BH masses, we select from the Fourth Data Re…
Bulge and Halo Kinematics Across the Hubble Sequence
Luis C. Ho
The correlation between the maximum rotational velocity of the disk (v_m) and the central stellar velocity dispersion of the bulge (sigma) offers insights into the relationship bet…
The Mass Function of Active Black Holes in the Local Universe
Jenny E. Greene, Luis C. Ho
We present the first measurement of the black hole (BH) mass function for broad-line active galaxies in the local Universe. Using the ~9000 broad-line active galaxies from the Four…
