CharlaMeasurement of a large scale flow with clusters of galaxies
Peculiar velocities of galaxies, derived using distance estimators, are plagued with systematic effects and are unreliable beyond 100 Mpc/h. In Kashlinsky &...

CharlaMeasuring the CMB Polarization with the Atacama Cosmology Telescope.
We have learned a great deal about the universe from measurements ofthe cosmic microwave background (CMB). Most of what we have learned so far has been based on...
