I review results from Chandra observations of nearby normal edge-on galaxies (Sd to Sa types). These galaxies have a broad range of star formation rate, but none of them is dominated by a nuclear star...
I review studies of the hot gaseous medium in and around nearby normal disk galaxies, including the Milky Way. This medium represents a reservoir of materials required for lasting star formation, a de...
The stellar and gaseous content of massive low surface brightness disk galaxies
Multiple wavelength Subset. Extreme type Galaxy Atomic gas Spiral galaxies
2014/12/9
This dissertation presents a multi-wavelength study of a subset of an extreme type of galaxy, those which have low surface brightnesses large disks, and large amounts of atomic gas, yet which have tot...

Black Hole growth and AGN obscuration by instability-driven inflows in high-redshift disk galaxies fed by cold streams
instability-driven inflows high-redshift disk galaxies cold streams
2011/9/29
Disk galaxies at high redshift have been predicted to maintain high gas surface densities due to continuous feeding by intense cold streams leading to violent gravitational instability, transient feat...
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...

SPIRAL SOLITON SOLUTION FOR DISK GALAXIES
Galaxies spiral – Galaxies kinematics and dynamics–Methods analytical
2009/3/11
In this paper, weakly nonlinear dynamics of spiral galaxies is studied,
using reductive perturbation method. One primarely aims at the derivation
of possible soliton solution for two dimensional geo...
