Cosmology using Cluster Internal Velocity Dispersions
We compare the cumulative distribution of internal velocity dispersions of galaxy clusters,N(> σv), for a large observational sample to those obtained from a set of N– body simulations that we run for seven COBE–normalized cosmological scenarios. They are: the standard CDM (SCDM) and a tilted (n = 0.85) CDM (TCDM) model, a cold+hot DM (CHDM) model with Ων = 0.25, two low–density flat CDM (ΛCDM)...
متن کاملTesting Modified Gravity with Globular Cluster Velocity Dispersions
Globular clusters (GCs) in the Milky Way have characteristic velocity dispersions that are consistent with the predictions of Newtonian gravity, and may be at odds with Modified Newtonian Dynamics (MOND). We discuss a modified gravity (MOG) theory that successfully predicts galaxy rotation curves, galaxy cluster masses and velocity dispersions, lensing, and cosmological observations, yet produc...
متن کاملPhonon dispersions of cluster crystals.
We analyze the ground states and the elementary collective excitations (phonons) of a class of systems, which form cluster crystals in the absence of attractions. Whereas the regime of moderate-to-high temperatures in the phase diagram has been analyzed in detail by means of density functional considerations (Likos et al 2007 J. Chem. Phys. 126 224502), the present approach focuses on the compl...
متن کاملThe Observational Distribution of Internal Velocity Dispersions in Nearby Galaxy Clusters
We analyze the internal velocity dispersion, σ, of a sample of 172 nearby galaxy clusters (z≤ 0.15), each of which has at least 30 available galaxy redshifts, and spans a large richness range. Cluster membership selection is based on nonparametric methods. In the estimate of galaxy velocity dispersion we consider the effects of possible velocity anisotropies in galaxy orbits, the infall of late...
متن کاملSuper–star Cluster Velocity Dispersions and Virial Masses in the M82 Nuclear Starburst
We use high-resolution near-infrared spectroscopy from Keck Observatory to measure the stellar velocity dispersions of 19 super star clusters (SSCs) in the nuclear starburst of M82. The clusters have ages on the order of 10 Myr, which is many times longer than the crossing times implied by their velocity dispersions and radii. We therefore apply the Virial Theorem to derive the kinematic mass f...
