Magnetic fields at galactic and larger scales is a challenging issue for astrophysics and cosmology. In this talk, I'll review the methods to detect magnetic...
Cosmological and astrophysical e xperimental data demark a large share of the limits of our knowledge in fundamental physics. I'll review two pieces of evidence...
Contrary to popular belief, on very large distance scales visible matter stubbornly refuses to "fall" according to the laws of gravity of both Newton and...
Measurement 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 &...
Measuring Dark Energy with Massive Redshift Surveys
The Baryon Oscillation Spectroscopic Survey (BOSS) is a Stage III dark energy experiment on the Sloan Telescope. For the five years from 2009-2014, we are...
Measuring 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...
