The exact numerical treatment of inflationary models
Christophe Ringeval
The precision reached by the recent CMB measurements gives new insights into the shape of the primordial power spectra of the cosmological perturbations. In the context of inflatio…
Mass estimates from stellar proper motions: The mass of Centauri
Richard D'Souza, Hans-Walter Rix
A projected mass estimator and a maximum likelihood estimator are developed to best determine the mass of stellar clusters from proper motion data. Both methods effectively account…
Subarcsecond Submillimeter Imaging of the Ultracompact HII Region G5.89-0.39
T. R. Hunter, C. L. Brogan, R. Indebetouw +1
We present the first subarcsecond submillimeter images of the enigmatic ultracompact HII region (UCHII) G5.89-0.39. Observed with the SMA, the 875 micron continuum emission exhibit…
Solutions to the "General Grand Unification Problem," and the Questions "How Did Our Universe Come Into Being?" and "Of What is Empty Space Composed?"
Robert A. Herrmann
Using mathematical techniques to model one of the most simplistic of human linguistic processes, it is rationally predicted that within the nonstandard physical world (NSP-world) t…
Dark matter in elliptical galaxies: II. Estimating the mass within the virial radius
Gary A. Mamon, Ewa L. Lokas
Elliptical galaxies are modelled with a a 4-component model: Sersic stars, LCDM dark matter (DM), hot gas and central black hole. DM is negligible in the inner regions, which are d…
Dark matter in elliptical galaxies: I. Is the total mass density profile of the NFW form or even steeper?
Gary A. Mamon, Ewa L. Lokas
Elliptical galaxies are modelled as Sersic luminosity distributions with density profiles (DPs) for the total mass adopted from the DPs of haloes within dissipationless LambdaCDM N…
