Chemical evolution of Seyfert galaxies [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe computed the chemical evolution of Seyfert galaxies, residing in spiral bulges, based on an updated model for the Milky Way bulge with updated calculations of the Galactic potential and of the feedback from the central supermassive black hole (BH) in a spherical approximation. We followed the evolution of bulges of masses 2 × 109 − 1011M⊙ by

HUBBLE SPACE TELESCOPE OBSERVATIONS OF SUB-DAMPED Lyα ABSORBERS AT z < 0.5, AND IMPLICATIONS FOR GALAXY CHEMICAL EVOLUTION [PDF]
, 2015 We report observations of four sub-damped Lyα (sub-DLA) quasar absorbers at z < 0.5 ?> obtained with the Hubble Space Telescope Cosmic Origins Spectrograph. We measure the available neutrals or ions of C, N, O, Si, P, S, Ar, Mn, Fe, and/or Ni.

Chemical evolution of ultra-faint dwarf galaxies in the self-consistently calculated integrated galactic IMF theory [PDF]
Astronomy & Astrophysics, 2020 The galaxy-wide stellar initial mass function (gwIMF) of a galaxy in dependence on its metallicity and star formation rate can be calculated by the integrated galactic IMF (IGIMF) theory.

A SPECTROSCOPIC STUDY OF BLUE SUPERGIANT STARS IN THE SCULPTOR GALAXY NGC 55: CHEMICAL EVOLUTION AND DISTANCE [PDF]
, 2016 Low-resolution (4.5–5 Å) spectra of 58 blue supergiant stars distributed over the disk of the Magellanic spiral galaxy NGC 55 in the Sculptor group are analyzed by means of non-LTE techniques to determine stellar temperatures, gravities, and ...

CONTRIBUTION OF NEUTRON STAR MERGERS TO THE r-PROCESS CHEMICAL EVOLUTION IN THE HIERARCHICAL GALAXY FORMATION [PDF]
, 2016 The main astronomical source of r-process elements has not yet been identified. One plausible site is neutron star mergers (NSMs), but from the perspective of the Galactic chemical evolution, it has been pointed out that NSMs cannot reproduce the ...

JWST/NIRSpec Measurements of Extremely Low Metallicities in High Equivalent Width Lyα Emitters
The Astrophysical Journal, 2023 Deep Very Large Telescope/MUSE optical integral field spectroscopy has recently revealed an abundant population of ultra-faint galaxies ( M _UV ≈ −15; 0.01 L _⋆ ) at z = 2.9−6.7 due to their strong Ly α emission with no detectable continuum.

CHEMICAL EVOLUTION LIBRARY FOR GALAXY FORMATION SIMULATION [PDF]
, 2016 We have developed a software library for chemical evolution simulations of galaxy formation under the simple stellar population (SSP) approximation. In this library, all of the necessary components concerning chemical evolution, such as initial mass ...

The Chemical Evolution of Galaxy Disks
, 2000 We discuss the main ingredients necessary to build models of chemical evolution of spiral galaxies and in particular the Milky Way galaxy. These ingredients include: the star formation rate, the initial mass function, the stellar yields and the gas flows.
