The Kormendy Relation in the First Billion Years: Evidence from JWST

The Astrophysical Journal Letters
Galaxy scaling relations encode key information about the structural, dynamical, and mass assembly histories of galaxies, and provide constraints on galaxy formation models as well as the onset of galaxy assembly.

The complex relationships between active galactic nuclei, bars, and bulges

Astronomy & Astrophysics
Context. Via scaling relations, it is well known that active galactic nuclei (AGNs) and bulges are linked. This link was thought to be driven by mergers, but recent studies show that secular processes are the dominant mechanism of supermassive black hole

Phosphorous in the Moderately Metal-poor Bulge Globular Clusters NGC 6539 and NGC 6569

The Astrophysical Journal
The distinct stellar populations of the Galactic bulge can be disentangled through detailed analysis of their chemical abundances and kinematical properties.

The chemical evolution of the Galactic Bulge seen through micro-lensing events

EPJ Web of Conferences, 2012
Galactic bulges are central to understanding galaxy formation and evolution. Here we report on recent studies using micro-lensing events to obtain spectra of high resolution and moderately high signal-to-noise ratios of dwarf stars in the Galactic bulge.

Galaxy Formation from the Primordial Black Holes

EPJ Web of Conferences, 2017
Supermassive black hole (SMBH) of size MBH = 106-10M⊙ is common in the Universe and it defines the center of the galaxy. A galaxy and the SMBH are generally thought to have co-evolved.
