The Formation of Galaxy Disks

open access: yes, 2008
We present a new set of multi-million particle SPH simulations of the formation of disk dominated galaxies in a cosmological context. Some of these galaxies are higher resolution versions of the models already described in Governato et al (2007).

Disk Galaxies and Galaxy Disks [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 2000
The conference Galaxy Disks and Disk Galaxies, sponsored by the Vatican Observatory, was held in June 12-16, 2000 at the Pontifical Gregorian University, in Rome (Italy). The meeting hosted about 230 participants coming from 30 countries. The very full program consisted of 29 review papers, 34 invited talks, and more than 180 posters.

GALAXY DISKS ARE SUBMAXIMAL [PDF]

open access: yesThe Astrophysical Journal, 2011
We measure the contribution of galaxy disks to the overall gravitational potential of 30 nearly face-on intermediate-to-late-type spirals from the DiskMass Survey. The central vertical velocity dispersion of the disk stars, sigma(z,R=0), is related to the maximum rotation speed (Vmax) as sigma(z,R=0) ~ 0.26 Vmax, consistent with previous measurements ...

Galaxy Disks [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2011
The disks of disk galaxies contain a substantial fraction of their baryonic matter and angular momentum, and much of the evolutionary activity in these galaxies, such as the formation of stars, spiral arms, bars and rings, and the various forms of secular evolution, takes place in their disks. The formation and evolution of galactic disks are therefore

Extended UV Disk (XUV-disk) Galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
AbstractMotivated by the GALEX discovery of recent star formation in outermost regions of M83 and NGC4625, we have investigated the nature of the XUV disks with follow-up high resolution imaging and spectroscopy, and attempted to detect them at other wavelengths (IR, Hα).

INTERLOCKING RESONANCE PATTERNS IN GALAXY DISKS [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2013
We have developed a method for finding dynamical resonances in disk galaxies using the change in sense of the radial component of the in-plane velocity at a resonance radius. Using simulations we show that we would expect to find these changes at corotation radii, with a weaker effect at the ILR and a small effect at the OLR. The method works well with

CDM, Feedback and the Hubble Sequence [PDF]

open access: yes, 2002
We have performed TreeSPH simulations of galaxy formation in a standard LCDM cosmology, including effects of star formation, energetic stellar feedback processes and a meta-galactic UV field, and obtain a mix of disk, lenticular and elliptical galaxies ...

The Potential-Density Phase Shift Method for Determining the Corotation Radii in Spiral and Barred Galaxies [PDF]

open access: yes, 2006
We have developed a new method for determining the corotation radii of density waves in disk galaxies, which makes use of the radial distribution of an azimuthal phase shift between the potential and density wave patterns.
