Formation and evolution of disk galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
Global star formation is the key to understanding galaxy disk formation. This in turn depends on gravitational instability of disks and continuing gas accretion as well as minor merging. A key component is feedback from supernovae.

Monolithic View of Galaxy Formation and Evolution [PDF]

open access: yesGalaxies, 2014
We review and critically discuss the current understanding of galaxy formation and evolution limited to Early Type Galaxies (ETGs) as inferred from the observational data and briefly contrast the hierarchical and quasi-monolithic paradigms of formation and evolution.

The star-formation history of the Milky Way Galaxy [PDF]

open access: yesProceedings of IAU Symposium 258, (2009), 'The Ages of Stars', eds Mamajek, Soderblom & Wyse p. 11-22, 2009
The star-formation histories of the main stellar components of the Milky Way constrain critical aspects of galaxy formation and evolution. I discuss recent determinations of such histories, together with their interpretation in terms of theories of disk ...

On the Formation and Evolution of cD Galaxies [PDF]

open access: yesarXiv, 2008
The cannibalism mechanism of formation of cD galaxies in clusters of Bautz-Morgan class I is analyzed. Dependences between absolute magnitude of cD galaxies, and of the clusters in which they reside (richness, redshifts) are considered. Evidences are presented in favor of formation of cD galaxies by cannibalism and their evolution.

GAIA: Composition, Formation and Evolution of the Galaxy [PDF]

open access: yesAstronomy & Astrophysics, 2001
The GAIA astrometric mission has recently been approved as one of the next two `cornerstones' of ESA's science programme, with a launch date target of not later than mid-2012.

Stellar populations in gas-rich galaxy mergers I. Dependence on star formation history [PDF]

open access: yes, 1998
We investigate the nature of stellar populations of major galaxy mergers between late-type spirals considerably abundant in interstellar medium by performing numerical simulations designed to solve both the dynamical and chemical evolution in a self ...

The evolution of the colour-magnitude relation and of the star formation activity in galaxy clusters since z~0.8 [PDF]

open access: yesarXiv, 2008
We present recent results on the evolution of the colour-magnitude relation and of the star formation activity in galaxy clusters since z~0.8. Results are based on the ESO Distant Cluster Survey (EDisCS) - an ESO large programme aimed at the study of ...

Morphologies of Galaxies at z ≳ 9 Uncovered by JWST/NIRCam Imaging: Cosmic Size Evolution and an Identification of an Extremely Compact Bright Galaxy at z ∼ 12

open access: yesThe Astrophysical Journal, 2023
We present morphologies of galaxies at z ≳ 9 resolved by JWST/NIRCam 2–5 μ m imaging. Our sample consists of 22 galaxy candidates identified by stringent dropout and photo- z criteria in GLASS, CEERS, SMACS J0723, and Stephan’s Quintet flanking fields ...
