Measuring the Cosmological Constant Through the Lyman -Alpha Forest Using the Alcock -Paczynski Test
… ∼ 4. Recently the concept of performing the Alcock-Paczynski test on the Lyalpha forest to determine the cosmological constant has been proposed. This motivates us to develop a methodology incorporating sophisticated cosmological hydrodynamics simulations including these effects to implement …

Cosmological constraints using 2- and 3-point correlations with meerkat, the ska and other surveys
… instrumental noise, foreground avoidance, the Alcock-Paczynski effect, and theoretical modeling errors in the correlators. The investigation also includes assessments of 21-cm clustering bias up to the second order.
