Context. Outflows accelerated by active galactic nuclei (AGN) are commonly observed in the
form of coherent, mildly collimated high-velocity gas directed along the AGN ionisation …

The final product of galaxy evolution through cosmic time is the population of galaxies in the
local universe. These galaxies are also those that can be studied in most detail, thus …

We present an observational constraint for the typical active galactic nucleus (AGN) phase
lifetime. The argument is based on the time lag between an AGN central engine switching …

We present a new model of the nebular emission from star-forming galaxies in a wide range
of chemical compositions, appropriate to interpret observations of galaxies at all cosmic …

We present a sample of 151 dwarf galaxies (10 8.5≲ M⋆≲ 10 9.5 M☉) that exhibit optical
spectroscopic signatures of accreting massive black holes (BHs), increasing the number of …

Using observations from the MOSFIRE Deep Evolution Field survey, we investigate the
physical conditions of star-forming regions in z∼ 2.3 galaxies, specifically the electron …

Massive black holes (BHs) are at once exotic and yet ubiquitous, residing at the centers of
massive galaxies in the local Universe. Recent years have seen remarkable advances in …

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 …

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 present a detailed study of the rest-optical (3600–7000 Å) nebular spectra of∼ 380 star-
forming galaxies at $ z\simeq 2\mbox {--} 3$, obtained with Keck/Multi-object Spectrometer …
