Refractive Convergent Plasma Lenses explain ESE and pulsar scintillation
Ue-Li Pen, Lindsay King
We propose convergent plasma lenses, possibly from current sheets, as a generic solution to strong interstellar scattering. These lenses resolve the overpressure problem by geometr…
Non-Gaussian Error in Galaxy Survey (Part 1)
Joachim Harnois-Deraps, Ue-Li Pen
We propose a method to estimate non-Gaussian error bars on the matter power spectrum from galaxy surveys in the presence of non-trivial survey selection functions. The estimators a…
Can 21-cm observations discriminate between high-mass and low-mass galaxies as reionization sources?
Ilian T. Iliev, Garrelt Mellema, Paul R. Shapiro +4
The prospect of detecting the first galaxies by observing their impact on the intergalactic medium as they reionized it during the first billion years leads us to ask whether such…
Non-Gaussian errors of baryonic acoustic oscillations
Wai-Hin Wayne Ngan, Joachim Harnois-Déraps, Ue-Li Pen +2
We revisit the uncertainty in baryon acoustic oscillation (BAO) forecasts and data analyses. In particular, we study how much the uncertainties on both the measured mean dilation s…
