An analytical model of surface mass densities of cold dark matter haloes - with an application to MACHO microlensing optical depths
Janne Holopainen, Erik Zackrisson, Alexander Knebe +5
The cold dark matter (CDM) scenario generically predicts the existence of triaxial dark matter haloes which contain notable amounts of substructure. However, analytical halo models…
Subhaloes in CDM cosmological simulations: I. Masses and abundances
P. Nurmi, P. Heinämäki, E. Saar +4
If the concordance CDM model is a true description of the universe, it should also properly predict the properties and structure of dark matter haloes, where galaxies are born.…
MACHOs in dark matter haloes
Janne Holopainen, Chris Flynn, Alexander Knebe +2
Using eight dark matter haloes extracted from fully-self consistent cosmological N-body simulations, we perform microlensing experiments. A hypothetical observer is placed at a dis…
Luminosity limits on white dwarfs in a Galactic shroud
Janne Holopainen, Chris Flynn
We place observational constraints on a recently proposed Galactic population, dubbed the shroud (Gyuk & Gates 1999, Gates & Gyuk 2001). The shroud would be a very thick Galactic d…
Photometric Properties of White Dwarf Dominated Halos
H. -c. Lee, B. K. Gibson, Y. Fenner +5
Using stellar population synthesis techniques, we explore the photometric signatures of white dwarf progenitor dominated galactic halos, in order to constrain the fraction of halo…
White dwarfs and Galactic dark matter
Chris Flynn, Janne Holopainen, Johan Holmberg
We discuss the recent discovery by Oppenheimer et al (2001) of old, cool white dwarf stars, which may be the first direct detection of Galactic halo dark matter. We argue here that…
