Interpreting the Evolution of the Size - Luminosity Relation for Disk Galaxies from Redshift 1 to the Present
galaxies evolution — galaxies formation — methods N-Body simulations
2010/11/9
A sample of very high resolution cosmological disk galaxy simulations is used to investigate the evolution of galaxy disk sizes back to redshift 1 within the CDM cosmology. Artificial images in the r...
Modelling the spectral energy distribution of galaxies. V. The dust and PAH emission SEDs of disk galaxies
Radiative transfer - Scattering - (ISM): dust extinction - Galaxies spiral - Galaxies: individual
2010/11/15
We present a self-consistent model of the spectral energy distributions (SEDs) of spiral galaxies from the ultraviolet (UV) to the mid-infrared (MIR)/far-infrared (FIR)/submillimeter (submm) based on ...
Properties of Bulgeless Disk Galaxies: I. Atomic Gas
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We study the neutral hydrogen properties of a sample of twenty bulgeless disk galaxies (Sd - Sdm Hubble types), an interesting class because their morphological simplicity implies that they have evolv...
High star formation rates as the origin of turbulence in early and modern disk galaxies
Galaxy Astrophysics (astro-ph.GA) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
High spatial and spectral resolution observations of star formation and kinematics in early galaxies have shown that two-thirds are massive rotating disk galaxies with the remainder being less massive...
