Ly-alpha Radiative Transfer in Cosmological Simulations and Application to a z~8 Emitter
Argyro Tasitsiomi
We develop a Ly-alpha radiative transfer (RT) Monte Carlo code for cosmological simulations.High resolution,along with appropriately treated cooling can result in simulated environ…
Mass accretion histories & density profiles of LCDM clusters
Argyro Tasitsiomi
We analyze the mass accretion histories (MAHs) and density profiles of cluster-size halos in a flat LCDM cosmology.To fit the MAHs of all systems we need to generalize the MAH fit…
Cross-Correlation Lensing: Determining Galaxy and Cluster Mass Profiles from Statistical Weak Lensing Measurements
David E. Johnston, Erin S. Sheldon, Argyro Tasitsiomi +3
We present a new non-parametric method for determining mean 3D density and mass profiles from weak lensing measurements around stacked samples of galaxies or clusters, that is, fro…
Pairwise velocities in the Halo Model: Luminosity and Scale Dependence
Anze Slosar, Uros Seljak, Argyro Tasitsiomi
We investigate the properties of the pairwise velocity dispersion as a function of galaxy luminosity in the context of a halo model. We derive the distribution of velocities of pai…
Neutralino annihilation in the Large Magellanic Cloud
Argyro Tasitsiomi
I present results with respect to the gamma-ray and synchrotron fluxes due to neutralino annihilation in the Large Magellanic Cloud based on Tasitsiomi et al., Astrop. Phys. 21, 63…
