This review describes recent developments related to the unified model of active galactic
nuclei (AGNs). It focuses on new ideas about the origin and properties of the central …

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 …

We study the spatially resolved excitation properties of the ionized gas in a sample of 646
galaxies using integral field spectroscopy data from the Sloan Digital Sky Survey IV Mapping …

Stars that interact with supermassive black holes (SMBHs) can be either completely or
partially destroyed by tides. In a partial tidal disruption event (TDE), the high-density core of …

We use integral field spectroscopy from the PHANGS–MUSE survey, which resolves the
ionised interstellar medium structure at∼ 50 pc resolution in 19 nearby spiral galaxies, to …

We present Keck–MOSFIRE H and K spectra for a sample of 24 candidate quiescent
galaxies at 3< z< 4, identified from their rest-frame UVJ colors and photometric redshifts in …

A sample of 18 286 radio-loud active galactic nuclei (AGN) is presented, constructed by
combining the seventh data release of the Sloan Digital Sky Survey with the NRAO (National …

We investigate the stellar populations for a sample of 24 quiescent galaxies at 1.5< z< 2.5
using deep rest-frame optical spectra obtained with Keck MOSFIRE. By fitting templates …

We present the largest and most homogeneous catalog of H ii regions and associations
compiled so far. The catalog comprises more than 7000 ionized regions, extracted from 306 …

We study the gas phase metallicity (O/H) and nitrogen abundance gradients traced by star-
forming regions in a representative sample of 550 nearby galaxies in the stellar mass range …
