How to measure CMB polarization power spectra without losing information
Max Tegmark, Angelica de Oliveira-Costa
We present a method for measuring CMB polarization power spectra given incomplete sky coverage and test it with simulated examples such as Boomerang 2001 and MAP. By augmenting the…
Constraints from the Lyman alpha forest power spectrum
Matias Zaldarriaga, Lam Hui, Max Tegmark
We use published measurements of the transmission power spectrum of the Lyman alpha forest to constrain several parameters that describe cosmology and thermal properties of the int…
A New Spin on Galactic Dust
Angelica de Oliveira-Costa, Max Tegmark, Douglas P. Finkbeiner +9
We present a new puzzle involving Galactic microwave emission and attempt to resolve it. On one hand, a cross-correlation analysis of the WHAM H-alpha map with the Tenerife 10 and…
Latest cosmological constraints on the densities of hot and cold dark matter
Max Tegmark, Matias Zaldarriaga, Andrew J. S. Hamilton
As experimentalists step up their pursuit of cold dark matter particles and neutrino masses, cosmological constraints are tightening. We compute the joint constraints on 11 cosmolo…
The Real Space Power Spectrum of the PSCz Survey from 0.01 to 300 h/Mpc
Andrew J. S. Hamilton, Max Tegmark
We report a measurement of the real space (not redshift space) power spectrum of galaxies over four and a half decades of wavenumber, 0.01 to 300 h/Mpc, from the IRAS Point Source…
Why is the Fraction of Four-Image Radio Lens Systems So High?
D. Rusin, Max Tegmark
We investigate the frequency of two- and four-image gravitational lens systems in the Jodrell-VLA Astrometric Survey (JVAS) and Cosmic Lens All-Sky Survey (CLASS), and the possible…
