Synchronous Evolution of Galaxies in Groups: NGC 524 Group

, 2012
By means of panoramic spectroscopy at the SAO RAS BTA telescope, we investigated the properties of stellar populations in the central regions of five early-type galaxies -- the NGC 524 group members. The evolution of the central regions of galaxies looks

MAGICS. III. Seeds Sink Swiftly: Nuclear Star Clusters Dramatically Accelerate Seed Black Hole Mergers

The Astrophysical Journal
Merger rate predictions of massive black hole (MBH) seeds from large-scale cosmological simulations differ widely, with recent studies highlighting the challenge of low-mass MBH seeds failing to reach the galactic center, a phenomenon known as the seed ...

From Supermassive Black Holes to Dwarf Elliptical Nuclei: a Mass Continuum

, 2006
Considerable evidence suggests that supermassive black holes reside at the centers of massive galactic bulges. At a lower galactic mass range, many dwarf galaxies contain extremely compact nuclei that structurally resemble massive globular clusters.

The Demography of Super-Massive Black Holes: Growing Monsters at the Heart of Galaxies

, 2009
Supermassive black holes (BHs) appear to be ubiquitous at the center of all galaxies which have been observed at high enough sensitivities and resolution with the Hubble Space Telescope.

The Cosmic Owl: Twin Active Collisional Ring Galaxies with Starburst Merging Front at z = 1.14

The Astrophysical Journal
Galaxy mergers play a critical role in driving galaxy evolution, especially by transforming galaxy morphology, redistributing gas around galaxies, triggering active galactic nuclei (AGN), and stimulating star formation.

The Role of Starbursts in the Formation of Galaxies & Active Galactic Nuclei

, 1999
Starbursts are episodes of intense star-formation in the central regions of galaxies, and are the sites of roughly 25% of the high-mass star-formation in the local universe.
