Random interactions with disk galaxies

, 1996
Numerical simulations of galaxies have been used to study numerous characteristics and interactions of elliptical galaxies while disk galaxies have not been studied extensively with fully three-dimensional models of all components.

ALMA FACTS. II. Large Scale Variations in the 12CO(J = 2 – 1) to 12CO(J = 1 – 0) Line Ratio in Nearby Galaxies

The Astrophysical Journal
We present ^12 CO( J  = 1 – 0) mapping observations over ∼1/2 of the optical disk of 12 nearby galaxies from the Fundamental CO 1–0 Transition Survey of nearby galaxies (FACTS), using the ALMA Total Power array. Variations in the ^12 CO( J  = 2 − 1)/ ^12

What is a Halo? Observations of Faint Starlight Around Disk Galaxies

, 2007
. Early observations of the stellar halos of nearby disk galaxies are discussed. Since most of the currently available data come from deep CCD surface photometry, and it can be difficult to discriminate between spatially overlapping populations with this

Triple Bars And Complex Central Structures In Disk Galaxies

, 2007
We present an analysis of ground-based and HST images of three early-type barred galaxies. The first, NGC 2681, may be the clearest example yet of a galaxy with three concentric bars.

Resonance Excitation And The Spiral-Ring Structure Of Disk Galaxies

, 2007
Rings are common in disk galaxies. These rings are either indistinguishable from a pair of tightly wound spirals, or themselves are a part of the spiral structure. Furthermore, their occurrence is seen coincident with a bar in the center.
