In the current JWST era, rest-frame UV spectra play a crucial role in enhancing our
understanding of the interstellar medium (ISM) and stellar properties of the first galaxies in …

Ultraviolet (UV) observations of local star-forming galaxies have begun to establish an
empirical baseline for interpreting the rest-UV spectra of reionization-era galaxies. However …

We present maps for the electron temperature in the inner kpc of three luminous Seyfert
galaxies: Mrk 79, Mrk 348, and Mrk 607 obtained from Gemini Multi-Object Spectrograph …

For the first time, the sulphur abundance relative to hydrogen (S/H) in the narrow-line
regions of a sample of Seyfert 2 nuclei (Sy 2s) has been derived via direct estimation of the …

For the first time, the helium abundance relative to hydrogen (He/H), which relied on direct
measurements of the electron temperature, has been derived in the narrow line regions …

We derive the metallicity (traced by the O/H abundance) of the narrow-line region (NLR) of
108 Seyfert galaxies as well as radial metallicity gradients along their galaxy discs and of …

We investigate the discrepancy between oxygen abundance estimations for narrow-line
regions of active galactic nuclei (AGNs) type Seyfert 2 derived using direct estimations of the …

Line ratio diagnostics provide valuable clues as to the source of ionizing radiation in
galaxies with intense black hole accretion and starbursting events, such as local Seyfert …

ABSTRACT Using new Very Large Telescope (VLT)/XShooter spectral observations we
analyse the physical properties of five z∼ 0.3–0.4 confirmed Lyman continuum (LyC) …

We investigate the ionized gas kinematics, physical properties, and chemical abundances of
Sloan Digital Sky Survey J 142947, a Green Pea galaxy at redshift z∼ 0.17 with strong …
