Galaxy Evolution from Deep Galaxy Counts [PDF]
Symposium - International Astronomical Union, 1995 We present deep galaxy number counts and colours of K ā band selected galaxy surveys. We argue that primeval galaxies are present within the survey data, but have remained unidentified. There are few objects with the colours of an Lā elliptical galaxy at a redshift of z ā 1, in contradiction to standard luminosity evolution models.

Gas Circulation and Galaxy Evolution [PDF]
AIP Conference Proceedings, 2010 Galaxies must form and evolve via the acquisition of gas from the intergalactic environment, however the way this gas accretion takes place is still poorly understood. Star-forming galaxies are surrounded by multiphase halos that appear to be mostly produced by internal processes, e.g., galactic fountains.

Cosmological evolution of galaxies [PDF]
, 2013 I review the subject of the cosmological evolution of galaxies, including different aspects of growth in disk galaxies, by focussing on the angular momentum problem, mergers, and their by-products. I discuss the alternative to merger-driven growth -- cold accretion and related issues.

Secular evolution in barred galaxies [PDF]
, 2007 A strong bar rotating within a massive halo should lose angular momentum to the halo through dynamical friction, as predicted by Weinberg. We have conducted fully self-consistent, numerical simulations of barred galaxy models with a live halo population and find that bars are indeed braked very rapidly.

Galaxy Evolution in Distant Clusters [PDF]
Symposium - International Astronomical Union, 1996 A significant evolution has been detected in intermediate redshift clusters (z < 0.9), first by photometric studies ([1], [2]), which showed an excess of blue objects; subsequent spectroscopic studies revealed anomalies in most of the galaxies, mainly consisting of excessively strong Balmer lines.

Scale Interactions and Galaxy Evolution [PDF]
Astrophysics and Space Science, 2003 To understand galaxies and their evolution, it is necessary to describe how the different scales interact: how the microscopic physics, such as star formation, or the large scale physics, such as galaxy interactions may modify the galaxy global shapes.

Chemo-dynamical Evolution of Galaxies
, 2023 Stars are fossils that retain the history of their host galaxies. Elements heavier than helium are created inside stars and are ejected when they die. From the spatial distribution of elements in galaxies, it is therefore possible to constrain the physical processes during galaxy formation and evolution.
