Probing the Local Group Medium toward Markarian 421 with Chandra and the Far Ultraviolet Spectroscopic Explorer
halo intergalactic medium
2014/12/24
We report the detection of highly ionized gas at z ~ 0 seen in resonant UV and X-ray absorption lines toward the z = 0.03 blazar Mrk 421. A total of 13 X-ray and three UV lines were measured (or upper...
We present high-resolution large-scale observations of the molecular and atomic gas in the Local Group galaxy M 33. The observations were carried out using the HEterodyne Receiver Array (HERA) at the ...
Local Group progenitors: Lyman Alpha bright?
cosmology: theory, galaxies: individual, galaxies: high redshift galaxies:intergalactic medium
2011/10/20
We present a novel approach of identifying the Milky Way (MW) and Andromeda (M31) progenitors that could be visible as LAEs at z~6: we couple a snapshot from the Constrained Local UniversE Simulations...
Renegade Subhaloes in the Local Group

2011/10/9
Using a dark matter only Constrained Local UniversE Simulation (CLUES) we examine the existence of subhaloes that change their affiliation from one of the two prominent hosts in the Local Group (i.e. ...
The dark matter assembly of the Local Group in constrained cosmological simulations of a LambdaCDM universe

2011/9/26
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
2011/1/11
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)
2010/12/28
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)
2010/12/28
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)
2010/12/27
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 ...

2010/10/29
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...
