The Baryonic Tully-Fisher Relation of Gas Rich Galaxies as a Test of LCDM and MOND
Baryonic Tully-Fisher Relation Rich Galaxies LCDM MOND

The Baryonic Tully-Fisher Relation (BTFR) is an empirical relation between baryonic mass and rotation velocity in disk galaxies. It provides tests of galaxy formation models in LCDM and of alternative...
Dynamics of the Magellanic Clouds in a LCDM Universe
Dynamics the Magellanic Clouds

2011/1/10
We examine Milky Way-Magellanic Cloud systems selected from the Millennium-II Simulation in order to place the orbits of the Magellanic Clouds in a cosmological context. Our analysis shows that satell...

We present a new proxy for the overdensity peak height for which the large-scale clustering of haloes of a given mass does not vary significantly with the assembly history.
A Series Solution to the Luminosity Distance in a Flat LCDM Universe

2010/11/15
Cosmological observations indicate that our universe is flat and dark energy (DE)
dominated at present. The luminosity distance plays an important role in the investigation
of the evolution and stru...
Simultaneous Falsification of LCDM and Quintessence with Massive, Distant Clusters
Falsification of LCDM Quintessence with Massive Distant Clusters
font style='font-size:12px;'>
2010/11/9
Observation of even a single massive cluster, especially at high redshift, can falsify the standard cosmological framework consisting of a cosmological constant and cold dark matter (CDM) with Gaussi...
The PN.S Elliptical Galaxy Survey: a standard LCDM halo around NGC 4374?
Cosmology and Extragalactic Astrophysics (astro-ph.CO)

2010/12/27
As part of our current programme to test LCDM predictions for dark matter (DM) haloes using extended kinematical observations of early-type galaxies, we present a dynamical analysis of the bright elli...
