Ages and metallicities of central and satellite galaxies: implications for galaxy formation and evolution [PDF]
, 2009 Using the stellar ages and metallicities of galaxies in the Sloan Digital Sky Survey (SDSS) obtained by Gallazzi et al. and the SDSS galaxy group catalogue of Yang et al., we study how the stellar ages and metallicities of central and satellite galaxies ...

THE EVOLUTION OF STAR FORMATION HISTORIES OF QUIESCENT GALAXIES [PDF]
The Astrophysical Journal, 2016 ABSTRACT Although there has been much progress in understanding how galaxies evolve, we still do not understand how and when they stop forming stars and become quiescent. We address this by applying our galaxy spectral energy distribution models, which incorporate physically motivated star formation histories (SFHs) from cosmological ...

The Evolution of the Mass-Metallicity Relation at 0.20 < z < 0.35 [PDF]
Journal of Astronomy and Space Sciences, 2013 We present a spectroscopic study of 343 blue compact galaxies (BCGs) at 0.20 < z < 0.35 from the Sloan Digital Sky Survey (SDSS) DR7 data. We derive gas phase oxygen abundance using the empirical and direct method.

The evolution of galaxy formation [PDF]
Astronomy & Geophysics, 2011 Our history of understanding galaxy formation could be traced through the development of individual ideas. A cynic might be tempted to suggest that new catchphrases are developed at a faster rate than genuine progress is made.

Internal Secular Evolution in Disk Galaxies: The Growth of Pseudobulges
, 2007 Observational and theoretical evidence that internal, slow ("secular") evolution reshapes galaxy disks is reviewed in Kormendy & Kennicutt (2004, ARAA, 42, 603). This update has three aims.

The GALEX Extended Mission: Surveying UV Tracers of the Hidden Side of Galaxy Evolution [PDF]
, 2010 The Galaxy Evolution Explorer (GALEX) continues its surveys of the ultraviolet sky. GALEX surveys have supported the following galaxy evolution investigations: calibrating UV as a star formation rate tracer, using wide and deep surveys to measure star ...

, 2011 Some of the extremely metal-poor Blue Compact Dwarf galaxies (XBCDs) in the nearby universe form galaxy pairs with remarkably similar properties. This fact points to an intriguing degree of synchronicity in the formation history of these binary dwarf ...

Merger Induced Globular Cluster Formation and Galaxy Evolution [PDF]
, 2008 Based on the earlier work of Gunn and McCrea we model the formation of globular clusters in merging galaxies. Neutral hydrogen observations of dwarf irregular galaxies as well as more luminous systems are used to provide the key parameters of the model ...

Dynamics of the response of dark matter halo to galaxy evolution in IllustrisTNG [PDF]
Journal of Cosmology and Astroparticle PhysicsWe present the dynamical evolution of the dark matter's relaxation response to galaxies and their connection to the astrophysical properties as simulated in the IllustrisTNG suite of cosmological hydrodynamical simulations.

The E-MOSAICS project: tracing galaxy formation and assembly with the age–metallicity distribution of globular clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present 25 cosmological zoom-in simulations of Milky Way-mass galaxies in the `MOdelling Star cluster population Assembly In Cosmological Simulations within EAGLE' (E-MOSAICS) project.
