Where Are the Baryons? II: Feedback Effects
Renyue Cen, Jeremiah P. Ostriker
Numerical simulations of the intergalactic medium have shown that at the present epoch a significant fraction (40-50%) of the baryonic component should be found in the (T~10^6K) Wa…
Testing a new analytic model for gravitational lensing probabilities
Sudeep Das, Jeremiah P. Ostriker
We study gravitational lensing with a multiple lens plane approach, proposing a simple analytical model for the probability distribution function (PDF) of the dark matter convergen…
Formation of early-type galaxies from cosmological initial conditions
Thorsten Naab, Peter H. Johansson, Jeremiah P. Ostriker +1
We describe high resolution Smoothed Particle Hydrodynamics (SPH) simulations of three approximately field galaxies starting from \LCDM initial conditions. The simulations ar…
Characterizing the Cluster Lens Population
Joseph F. Hennawi, Neal Dalal, Paul Bode +1
We present a detailed investigation into which properties of CDM halos make them effective strong gravitational lenses. Strong lensing cross sections of 878 clusters from an N-body…
A simple model for the evolution of disc galaxies: The Milky Way
Thorsten Naab, Jeremiah P. Ostriker
A simple model for the evolution of disc galaxies is presented. We adopt three numbers from observations of the Milky Way disc, the local surface mass density, the stellar scale le…
A Simple and Accurate Model for Intra-Cluster Gas
Jeremiah P. Ostriker, Paul Bode, Arif Babul
Starting with the well-known NFW dark matter halo distribution, we construct a simple polytropic model for the intracluster medium which is in good agreement with high resolution n…
