Damped Lyman Alpha Systems in Galaxy Formation Simulations
Andrew Pontzen, Fabio Governato, Max Pettini +6
We investigate the population of z=3 damped Lyman alpha absorbers (DLAs) in a recent series of high resolution galaxy formation simulations. The simulations are of interest because…
Direct Observational Test Rules Out Small MgII Absorbers
Andrew Pontzen, Paul Hewett, Robert Carswell +1
Recent observations suggest the incidence of strong intervening MgII absorption systems along the line-of-sight to gamma ray burst (GRB) afterglows is significantly higher than exp…
Bianchi Model CMB Polarization and its Implications for CMB Anomalies
Andrew Pontzen, Anthony Challinor
We derive the CMB radiative transfer equation in the form of a multipole hierarchy in the nearly-Friedmann-Robertson-Walker limit of homogeneous, but anisotropic, universes classif…
