Low-mass disc galaxies and the issue of stability: MOND vs dark matter
F. J. Sanchez-Salcedo, E. Martinez-Gomez, V. M. Aguirre-Torres +1
We analyse the rotation curves and gravitational stability of a sample of six bulgeless galaxies for which detailed images reveal no evidence for strong bars. We explore two scenar…
Interpreting the Distance Correlation Results for the COMBO-17 Survey
Mercedes T. Richards, Donald St. P. Richards, Elizabeth Martinez-Gomez
The accurate classification of galaxies in large-sample astrophysical databases of galaxy clusters depends sensitively on the ability to distinguish between morphological types, es…
Distance Correlation Methods for Discovering Associations in Large Astrophysical Databases
Elizabeth Martinez-Gomez, Mercedes T. Richards, Donald St. P. Richards
High-dimensional, large-sample astrophysical databases of galaxy clusters, such as the Chandra Deep Field South COMBO-17 database, provide measurements on many variables for thousa…
On the fraction of dark matter in charged massive particles (CHAMPs)
F. J. Sanchez-Salcedo, E. Martinez-Gomez, J. Magana
From various cosmological, astrophysical and terrestrial requirements, we derive conservative upper bounds on the present-day fraction of the mass of the Galactic dark matter (DM)…
A statistical model for the relation between exoplanets and their host stars
E. Martinez-Gomez, G. J. Babu
A general model is proposed to explain the relation between the extrasolar planets (or exoplanets) detected until June 2008 and the main characteristics of their host stars through…
Galactic constraints on CHAMPs
F. J. Sanchez-Salcedo, E. Martinez-Gomez
We improve earlier Galactic bounds that can be placed on the fraction of dark matter in charged elemental particles (CHAMPs). These constraints are of interest for CHAMPs whose mas…
