Marilena LoVerde (IAS) Lensing in the Lyman-alpha Forest:
In Lyman-alpha forest measurements it is generally assumed that quasars are mere background light sources that are uncorrelated with the forest. I will discuss how gravitational lensing of the quasars violates this assumption. This effect leads to a measurement bias, but more interestingly it provides a valuable signal. This signal will be challenging to observe but would provide a direct measure of how features in the Lyman-alpha forest trace the underlying mass density field thereby testing the hypothesis that fluctuations in the forest are driven by fluctuations in mass, rather than in the ionizing background, helium reionization or winds.
