Analysis of the Internal Radial Gradient of Chemical Abundances in Spiral Galaxies from CALIFA

open access: yesThe Astrophysical Journal
The study of chemical evolution is of paramount importance for understanding the evolution of galaxies. Models and observations propose an inside-out mechanism in the formation of spiral galaxy disks, implying a negative radial gradient of elemental ...

Insights into the Galactic Bulge Chemodynamical Properties from Gaia Data Release 3

open access: yesThe Astrophysical Journal
We explore the chemodynamical properties of the Galaxy in the azimuthal velocity V _ϕ and metallicity [Fe/H] space using red giant stars from Gaia Data Release 3.

The Milky Way Bulge Extratidal Star Survey: NGC 6569

open access: yesThe Astronomical Journal
We present spectroscopic evidence for tidal debris associated with the bulge globular cluster NGC 6569, based on medium-resolution ( R  ∼ 11,000) spectra of 303 stars obtained with the Anglo-Australian Telescope.

Reduction of the Bar Fraction in Paired Galaxies in the SDSS

open access: yesThe Astrophysical Journal
We investigate the bar fraction in galaxy pairs from the Sloan Digital Sky Survey to assess how galaxy interactions affect bar structures. Compared to isolated galaxies, close pairs exhibit a significantly reduced bar fraction at projected separations ...

Galaxy Bulges and Their Massive Black Holes: A Review [PDF]

open access: yes, 2016
With references to both key and oft-forgotten pioneering works, this article starts by presenting a review into how we came to believe in the existence of massive black holes at the centres of galaxies. It then presents the historical development of the near-linear (black hole)-(host spheroid) mass relation, before explaining why this has recently been

Early-type Galaxies on the Star Formation Main Sequence: Internal Star Formation Geometries Revealed with MaNGA and Their Environmental Origin

open access: yesThe Astrophysical Journal
Star-forming galaxies on the main sequence (MS) are often regarded as a uniform population characterized by similar global star formation properties. However, there exists a diversity in galaxy morphologies at a fixed stellar mass and star formation rate.

Chemical Evolution of Bulges of Active Galactic Nuclei in the Early Universe: Roles of Accreting Stars

open access: yesThe Astrophysical Journal
JWST/NIRCam observations reveal dense stellar cores in high-redshift galactic bulges, indicative of sustained star formation and potential stellar accretion.
