We review the use of emission lines for understanding galaxy evolution, focusing on
excitation source, metallicity, ionization parameter, ISM pressure, and electron density. We …

The evolution of the content of heavy elements in galaxies, the relative chemical
abundances, their spatial distribution, and how these scale with various galactic properties …

We report the discovery of an accreting supermassive black hole at z= 8.679. This galaxy,
denoted here as CEERS_1019, was previously discovered as a Lyα-break galaxy by …

We present rest-frame optical data of the compact z= 5.55 galaxy GS_3073 obtained using
the integral field spectroscopy mode of the Near-InfraRed Spectrograph on board the James …

We present emission-line ratios from a sample of 27 Lyman-break galaxies from z∼ 5.5− 9.5
with− 17.0< M 1500<− 20.4, measured from ultra-deep JWST/NIRSpec multi-object …

We present rest-frame optical emission-line flux ratio measurements for five z> 5 galaxies
observed by the James Webb Space Telescope Near-Infared Spectrograph (NIRSpec) in …

Context. LBQS 0302− 0019 is a blue quasar (QSO) at z∼ 3.3 that hosts powerful outflows
and resides in a complex environment consisting of an obscured active galactic nucleus …

Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-
sky survey. These 13 events were selected among X-ray transients detected in the 0°< l< …

We present an overview of a new integral field spectroscopic survey called MaNGA
(Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the …
