Dark Matter and Galaxy Formation: Challenges for the Next Decade
Joseph Silk
The origin of the galaxies represents an important focus of current cosmological research, both observational and theoretical. Its resolution involves a comprehensive understanding…
The Polytropic Equation of State of Primordial Gas Clouds
Marco Spaans, Joseph Silk
The polytropic equation of state (EOS) of primordial gas clouds with modest enrichment is computed, motivated by the recent observations of very Fe-deficient stars, [Fe/H]~10^{-3.5…
LOFAR as a Probe of the Sources of Cosmological Reionisation
Saleem Zaroubi, Joseph Silk
We propose use of the thickness of the ionisation front as a discriminant between alternative modes of reionisation in the early universe, by stars or by miniquasars. Assuming a ph…
Towards simulating star formation in the interstellar medium
A. Slyz, J. Devriendt, Greg Bryan +1
As a first step to a more complete understanding of the local physical processes which determine star formation rates (SFRs) in the interstellar medium (ISM), we have performed con…
Feedback and the Initial Mass function
Joseph Silk
I describe a turbulence-inspired model for the stellar initial mass function which includes feedback and self-regulation via protostellar outflows. A new aspect of the model provid…
Searching for Dark Matter with Future Cosmic Positron Experiments
Dan Hooper, Joseph Silk
Dark matter particles annihilating in the Galactic halo can provide a flux of positrons potentially observable in upcoming experiments, such as PAMELA and AMS-02. We discuss the sp…
