The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
The spatial distribution of polar hydrogen deposits on the Moon
V. R. Eke, L. F. A. Teodoro, R. C. Elphic
A new analysis of the Lunar Prospector epithermal neutron data is presented, providing an improved map of the distribution of hydrogen near to the lunar poles. This is achieved usi…
Drag-Gravity torques on galaxies in clusters: radial small-scale alignment effects
Alejandro González S., Luís F. A. Teodoro
We calculate the torque on galaxies in clusters due to gravity and to dynamical friction forces in order to study the possible origin of small-scale alignment effects as the result…
Effects of correlation between merging steps on the global halo formation
Jun Pan, Yougang Wang, Xuelei Chen +1
The excursion set theory of halo formation is modified by adopting the fractional Brownian motion, to account for possible correlation between merging steps. We worked out analytic…
Resolving the universe with multifractals
Cristiano Sabiu, Luis Teodoro, Martin Hendry
We present a new method for dealing with geometrical selection effects in galaxy surveys while using a multifractal framework. The power of multifractal analysis lies in its connec…
Peculiar Velocities into the Next Generation: Cosmological Parameters From Large Surveys without Bias from Nonlinear Structure
Alexandra Abate, Sarah Bridle, Luis F. A. Teodoro +2
We investigate methods to best estimate the normalisation of the mass density fluctuation power spectrum (sigma_8) using peculiar velocity data from a survey like the Six degree Fi…
