Collisional Stripping and Disruption of Super-Earths
Robert A. Marcus, Sarah T. Stewart, Dimitar Sasselov +1
The final stage of planet formation is dominated by collisions between planetary embryos. The dynamics of this stage determine the orbital configuration and the mass and compositio…
Seeding the formation of cold gaseous clouds in Milky Way size halos
Dušan Kereš, Lars Hernquist
We use one of the highest resolution cosmological SPH simulations to date to demonstrate that cold gaseous clouds form around Milky Way size galaxies. We further explore mechanisms…
A New Calculation of the Ionizing Background Spectrum and the Effects of HeII Reionization
C. -A. Faucher-Giguere, A. Lidz, M. Zaldarriaga +1
The ionizing background determines the ionization balance and the thermodynamics of the cosmic gas. It is therefore a fundamental ingredient to theoretical and empirical studies of…
Quasars Are Not Light-Bulbs: Testing Models of Quasar Lifetimes with the Observed Eddington Ratio Distribution
Philip F. Hopkins, Lars Hernquist
We use the observed distribution of Eddington ratios as a function of supermassive black hole (BH) mass to constrain models of AGN lifetimes and lightcurves. Given the observed AGN…
HeII Reionization and its Effect on the IGM
Matthew McQuinn, Adam Lidz, Matias Zaldarriaga +4
Observations of the intergalactic medium (IGM) suggest that quasars reionize HeII in the IGM at z ~ 3. We have run a set of 190 and 430 comoving Mpc simulations of HeII being reion…
Probing Reionization with the 21 cm-Galaxy Cross Power Spectrum
Adam Lidz, Oliver Zahn, Steven Furlanetto +3
The cross-correlation between high redshift galaxies and 21 cm emission from the high redshift intergalactic medium (IGM) promises to be an excellent probe of the Epoch of Reioniza…
