Dust Migration and Morphology in Optically Thin Circumstellar Gas Disks
Taku Takeuchi, Pawel Artymowicz
We analyze the dynamics of gas-dust coupling in the presence of stellar radiation pressure in circumstellar gas disks, which are in a transitional stage between the gas-dominated,…
Neutralino Gamma-ray Signals from Accreting Halo Dark Matter
Lars Bergstrom, Joakim Edsjo, Christofer Gunnarsson
There is mounting evidence that a self-consistent model for particle cold dark matter has to take into consideration spatial inhomogeneities on sub-galactic scales seen, for instan…
A new population of WIMPs in the solar system and indirect detection rates
Lars Bergstrom, Thibault Damour, Joakim Edsjo +2
A new Solar System population of Weakly Interacting Massive Particle (WIMP) dark matter has been proposed to exist. We investigate the implications of this population on indirect s…
DarkSUSY - A numerical package for dark matter calculations in the MSSM
Paolo Gondolo, Joakim Edsjo, Lars Bergstrom +2
The question of the nature of the dark matter in the Universe remains one of the most outstanding unsolved problems in basic science. One of the best motivated particle physics can…
Neutralino Dark Matter and Caustic Ring Signals
Christofer Gunnarsson
We have studied the effects on the gamma-ray flux on Earth by neutralino annihilations in caustic rings of dark matter in the Galactic halo. The caustic ring model by Sikivie has b…
Photoevaporating flows from the cometary knots in the Helix nebula (NGC 7293)
L. Lopez-Martin, A. C. Raga, G. Mellema +2
We explain the Ha emission of the cometary knots in the Helix Nebula (NGC 7293) with an analytical model that describes the emission of the head of the globules as a photoevaporate…
