Avoiding bias in reconstructing the largest observable scales from partial-sky data
Avoiding bias reconstructing largest observable partial-sky data
2011/10/18
Obscuration due to Galactic emission complicates the extraction of information from cosmological surveys, and requires some combination of the (typically imperfect) modeling and subtraction of foregro...
Reconstructing signals from noisy data with unknown signal and noise covariance
statistics, information theory, statistical mechanics
2011/10/8
We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The starting point ...
A Two-Tiered Correlation of Dark Matter with Missing Transverse Energy: Reconstructing the Lightest Supersymmetric Particle Mass at the LHC
Correlation Dark Matter Missing Transverse Energy Reconstructing Lightest Supersymmetric
2011/10/18
We suggest that non-trivial correlations between the dark matter particle mass and collider based probes of missing transverse energy H_T^miss may facilitate a two tiered approach to the initial disco...
Galactic astroarchaeology: reconstructing the bulge history by means of the newest data
Galaxy Astrophysics (astro-ph.GA) Cosmology and Extragalactic Astrophysics (astro-ph.CO) Solar and Stellar Astrophysics (astro-ph.SR)

The chemical abundances measured in stars of the Galactic bulge offer an unique opportunity to test galaxy formation models as well as impose strong constraints on the history of star formation and st...
