Supermassive black holes (BHs) have been found in 85 galaxies by dynamical modeling of
spatially resolved kinematics. The Hubble Space Telescope revolutionized BH research by …

Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical
gravitational backgrounds involving black holes or branes naturally lead to quasinormal …

We present improved black hole masses for 35 active galactic nuclei (AGNs) based on a
complete and consistent reanalysis of broad emission-line reverberation-map** data …

We derive improved versions of the relations between supermassive black hole mass (M
BH) and host-galaxy bulge velocity dispersion (σ) and luminosity (L; the M–σ and M–L …

Scaling relations between central black hole (BH) mass and host galaxy properties are of
fundamental importance to studies of BH and galaxy evolution throughout cosmic time. Here …

The formation of the first stars and quasars marks the transformation of the universe from its
smooth initial state to its clumpy current state. In popular cosmological models, the first …

We present four improved empirical relationships useful for estimating the central black hole
mass in nearby AGNs and distant luminous quasars alike using either optical or UV single …

The DEEP2 and COMBO-17 surveys are compared to study luminosity functions of red and
blue galaxies to z~ 1. The two surveys have different methods and sensitivities, but …

This review discusses the current status of supermassive black hole research, as seen from
a purely observational standpoint. Since the early '90s, rapid technological advances, most …

We assess models for the assembly of supermassive black holes (SMBHs) at the center of
galaxies that trace their hierarchical buildup far up in the dark halo" merger tree." Motivated …
