Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

Over the past two decades, an avalanche of new data from multiwavelength imaging and
spectroscopic surveys has revolutionized our view of galaxy formation and evolution. Here …

Context. Aims. Active galactic nuclei are known to have complex X-ray spectra that depend
on both the properties of the accreting super-massive black hole (eg mass, accretion rate) …

We summarize what large surveys of the contemporary Universe have taught us about the
physics and phenomenology of the processes that link the formation and evolution of …

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

The space-based Laser Interferometer Space Antenna (LISA) will be able to observe the
gravitational-wave signals from systems comprised of a massive black hole and a stellar …

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 …

Context. Feedback from accreting supermassive black holes (SMBHs) is often identified as
the main mechanism responsible for regulating star formation in active galactic nucleus …

We present an updated and revised analysis of the relationship between the Hβ broad-line
region (BLR) radius and the luminosity of the active galactic nucleus (AGN). Specifically, we …

In this paper, we provide updated constraints on the bolometric quasar luminosity function
(QLF) from z= 0 to z= 7. The constraints are based on an observational compilation that …
