How did it all begin?
Max Tegmark
How did it all begin? Although this question has undoubtedly lingered for as long as humans have walked the Earth, the answer still eludes us. Yet since my grandparents were born,…
Cosmology from Large Scale Structure
Andrew Hamilton, Nick Gnedin, Max Tegmark +1
We report on the linear matter power spectrum reconstructed from the Lyman alpha forest, on baryonic wiggles in the galaxy power spectrum, and on how to measure real space (as oppo…
Cosmic complementarity: probing the acceleration of the Universe
Max Tegmark, Daniel J. Eisenstein, Wayne Hu +1
We assess the accuracy with which Omega and Lambda can be measured by combining various types of upcoming experiments. Useful expressions for the Fisher information matrix are deri…
Uncorrelated measurements of the CMB power spectrum
Max Tegmark, Andrew Hamilton
We describe how to compute estimates of the power spectrum C_l from Cosmic Microwave Background (CMB) maps that not only retain all the cosmological information, but also have unco…
Doppler peaks and all that: CMB anisotropies and what they can tell us
Max Tegmark
The power spectrum of fluctuations in the cosmic microwave background (CMB) depends on most of the key cosmological parameters. Accurate future measurements of this power spectrum…
