The dark matter assembly of the Local Group in constrained cosmological simulations of a LambdaCDM universe
galaxies:haloes cosmology:theory methods
2011/6/30
We make detailed theoretical predictions for the assembly properties of the Local Group (LG) in the standard LambdaCDM cosmological model. We use three cosmological N-body dark matter simulations from...
The luminosities of backsplash galaxies in constrained simulations of the Local Group
backsplash galaxies constrained simulations the Local Group
2010/11/30
We study the differences and similarities in the luminosities of bound, infalling and the so-called backsplash (Gill et al. 2005) galaxies of the Milky Way and M31 using a hydrodynamical simulation pe...
In savvy pursuit of Local Group blue massive stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/10/11
The important role of metallicity on massive star evolution and the combination of multi-object spectrographs and 10m class telescopes, have lead to numerous systematic studies of massive stars in Loc...
Hierarchical Stellar Structures in the Local Group Dwarf Galaxy NGC 6822
Galaxy Astrophysics (astro-ph.GA) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/10/10
We present a comprehensive study of the star cluster population and the hierarchical structure in the clustering of blue stars with ages <~ 500 Myr in the Local Group dwarf irregular galaxy NGC 6822. ...
The preferred direction of infalling satellite galaxies in the Local Group
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/10/7
Using a high resolution DM simulation of the Local Group (LG), conducted within the framework of the Constrained Local UniversE Simulation (CLUES) project, we investigate the nature of how satellites ...
MULTIFREQUENCY OBSERVATIONS OF ONE OF THE LARGEST SUPERNOVA REMNANTS IN THE LOCAL GROUP OF GALAXIES, LMC - SNR J0450-709
ISM: supernova remnants Magellanic Clouds Radio Continuum:ISM Polarisation ISM: individual objects : SNR J0450-709
2009/9/2
We present the results of new Australia Telescope Compact Array (ATCA) observations of one of the largest supernova remnants, SNR J0450{709, in the Local Group of galaxies. We found that this Large Ma...
