Effects of large-scale structure on the accuracy of weak lensing mass measurements
cosmology observations dark matter large-scale structure of Uni-verse galaxies clusters
2010/11/10
Weak gravitational lensing has become an important method to determine the masses of galaxy clusters. The intrinsic shapes of the galaxies are a dominant source of uncertainty, but there are other lim...
Ultimate quantum bounds on mass measurements with a nano-mechanical oscillator
Ultimate quantum bounds mass measurements nano-mechanical oscillator
2010/10/21
Nano-mechanical resonators have a large potential as sensors of very small adsorbed masses,
down to the atomic level and beyond. Here I establish the fundamental lower bound on the mass
that can be ...
