An optical/NIR survey of globular clusters in early-type galaxies II. Ages of GC systems and the relation to galaxy morphology
globular clusters early-type galaxies II
font style='font-size:12px;'>
2011/1/10
Context: Some photometric studies of extragalactic globular cluster (GC) systems using the optical and near-infrared colour combination have suggested the presence of a large fraction of intermediate-...
Thin shell morphology in the circumstellar medium of massive binaries
Hydrodynamics – Stars binaries general – Stars circumstellar matter – Stars massive – Stars winds outflows
font style='font-size:12px;'>
2010/11/11
Context. In massive binaries, the powerful stellar winds of the two stars collide, leading to the formation of shock-dominated environments that can be modelled only in 3D.
The Morphology of the Expanding Ejecta of V2491 Cygni (2008 N.2)
line profiles – stars novae – stars individual V2491 Cyg
font style='font-size:12px;'>
2010/11/12
Determining the evolution of the ejecta morphology of novae provides valuable information
on the shaping mechanisms in operation at early stages of the nova outburst. Understanding
such mechanisms h...
Effects of non-uniform interstellar magnetic field on synchrotron X-ray and inverse-Compton gamma-ray morphology of SNRs
Magnetohydrodynamics (MHD) Radiation mechanisms non-thermal Shock waves ISM
font style='font-size:12px;'>
2010/11/12
Context. Observations of SNRs in X-ray and γ-ray bands promise to contribute with important information in our understanding of the kinematics of charged particles and magnetic fields in the vicinity ...
Optical multiband surface photometry of a sample of Seyfert galaxies. I. Large-scale morphology and local environment analysis of matched Seyfert and inactive galaxy samples
galaxies Seyfert – galaxies structure – techniques image processing – techniques photometric
font style='font-size:12px;'>
2010/11/12
Context. Parallel analysis of the large-scale morphology and local environment of matched active and control galaxy samples plays an important role in studies of the fueling of active galactic nuclei.
Differential Morphology Between Rest-frame Optical and UV Emission from 1.5 < z < 3 Star-forming Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
font style='font-size:12px;'>
2010/12/27
We present the results of a comparative study of the rest-frame optical and rest-frame ultraviolet morphological properties of 117 star-forming galaxies (SFGs), including BX, BzK, and Lyman break gala...
Morphology and Size Differences between Local & High Redshift Luminous Infrared Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/24
We show that the star-forming regions in high-redshift luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) and submillimeter galaxies (SMGs) have similar physical scales to those in local ...
Color Magnitude Relation and Morphology of Low-Redshift ULIRGs in SDSS
Color Magnitude Relation Low-Redshift ULIRGs
font style='font-size:12px;'>
2010/3/8
We present color-magnitude and morphological analysis of 54 low-redshift ULIRGs, a subset of the IRAS 1Jy sample (Kim & Sanders, 1998), in the SDSS. The ULIRGs are on average 1 magnitude brighter in M...
