Dark Matter Properties and Halo Central Densities
Using an analytic model calibrated against numerical simulations, we calculate the central densities of dark matter halos in a “conventional” cold dark matter model with a cosmological constant (LCDM) and in a “tilted” model (TLCDM) with slightly modified parameters motivated by recent analyses of Lyα forest data. We also calculate how warm dark matter (WDM) would modify these predicted densiti...
متن کاملThe Mass-Function of Low Mass Halo Stars: Limits on Baryonic Halo Dark Matter
We derive mass functions for halo red dwarfs (stars just massive enough to burn hydrogen) with varying assumptions about metallicity and about possible unresolved binaries in the sample. The mass functions are obtained from the luminosity function of a sample of 114 local halo stars in the USNO parallax survey (Dahn et al. 1995); we use stellar models of Alexander et al. (1996). We find that th...
متن کاملLimits on Stellar Objects as the Dark Matter of Our Halo: Nonbaryonic Dark Matter Seems to Be Required
The nature of the dark matter in the Halo of our Galaxy remains a mystery. Arguments are presented that the dark matter does not consist of ordinary stellar or substellar objects, i.e., the dark matter is not made of faint stars, brown dwarfs, white dwarfs, or neutron stars. In fact, faint stars and brown dwarfs constitute no more than a few percent of the mass of our Galaxy, and stellar remnan...
متن کاملTaking Halo-independent dark matter methods out of the bin
We develop a new halo-independent strategy for analyzing emerging DM hints, utilizing the method of extended maximum likelihood. This approach does not require the binning of events, making it uniquely suited to the analysis of emerging DM direct detection hints. It determines a preferred envelope, at a given confidence level, for the DM velocity integral which best fits the data using all avai...
متن کاملHalo-independent methods for inelastic dark matter scattering
We present halo-independent methods to analyze the results of dark matter direct detection experiments assuming inelastic scattering. We focus on the annual modulation signal reported by DAMA/LIBRA and present three different halo-independent tests. First, we compare it to the upper limit on the unmodulated rate from XENON100 using (a) the trivial requirement that the amplitude of the annual mo...
