Isocurvature modes and Baryon Acoustic Oscillations II: gains from combining CMB and Large Scale Structure
Baryon Acoustic Oscillations combining CMB Large Scale Structure
2011/9/29
We consider cosmological parameters estimation in the presence of a non-zero isocurvature contribution in the primordial perturbations. A previous analysis showed that even a tiny amount of isocurvatu...
Discovering the missing 2.2combining optical variability and optical/near-IR colors
Discovering missing quasars combining variability optical/near-IR colors
2011/9/27
The identifications of quasars in the redshift range 2.2inefficient as their optical colors are indistinguishable from those of stars. Recent studies have proposed to use opt...
Combining cluster observables and stacked weak lensing to probe dark energy: Self-calibration of systematic uncertainties
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We develop a new method of combining cluster observables (number counts and cluster-cluster correlation functions) and stacked weak lensing signals of background galaxy shapes, both of which are avail...
Inductive Magnetic Footpoint Tracking by Combining the Minimum Energy Fit with the Local Correlation Tracking and Doppler Velocity
Velocity magnetic field induction equation
2010/9/15
Time-dependent magneto-hydrodynamic simulations of active region coronal magnetic field require the underlying photospheric magnetic footpoint velocities. The minimum energy fit (MEF) is a new velocit...
