Fragmentation of Expanding Shells in Spiral and Irregular Galaxies

open access: yesAstronomy & Astrophysics, 1997
Conditions for the fragmentation of expanding shells due to gravitational instability are discussed. The self-similar analytical solution is compared with the results of 3-dimensional computer simulations for the expansion into homogeneous media. For realistic galactic disks we show that the formation of fragments is influenced by the amount of energy ...

ON THE STAR FORMATION LAW FOR SPIRAL AND IRREGULAR GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2015
A dynamical model for star formation on a galactic scale is proposed in which the interstellar medium is constantly condensing to star-forming clouds on the dynamical time of the average midplane density, and the clouds are constantly being disrupted on the dynamical time scale appropriate for their higher density.

Genuine Irregular Galaxies as a Relic of Building Blocks of Galaxies

open access: yes, 2013
In order to understand nature of building blocks of galaxies in the early universe, we investigate "genuine irregular galaxies (GIGs)" in the nearby universe. Here, GIGs are defined as isolated galaxies without regular structures (spheroid, bulge, disk, bar, spiral arm, and nucleus). Using the results of two excellent studies on galaxy morphology based
