Characterization And Analysis Of The Astrometric Errors In The Global Astrometric Solution For Gaia

Berry Holl, Lennart Lindegren, David Hobbs
2012 Zenodo  
We derive a covariance series expansion model that allows the efficient and accurate estimation of the covariance between any pair of astrometric parameters using only a limited amount of input data.  ...  Because the observations will be dominated by photon noise this is a good approximation of reality.  ...  The next step is to translate the observed direction of the source to the rotating SRS system, for which we need a model of the orientation of the satellite at any moment in the mission.  ...

Subleading Corrections to Hadronic Cross-Sections at High Energies [article]

James D. Cockburn
2017 arXiv   pre-print
A strong knowledge of the properties of amplitudes for Quantum Chromodynamics in the High Energy Limit is therefore important to interpret this data.  ...  The Large Hadron Collider (LHC) has provided, and will continue to provide, data for collisions at the highest energies ever seen in a particle accelerator.  ...  The predictions for both HEJ and HEJ+ARIADNE are shown for an observable related to the angular decorrelation of the dijet system.  ...

Cosmological searches for the neutrino mass scale and mass ordering [article]

Sunny Vagnozzi
2019 arXiv   pre-print
I show that failure to define the bias appropriately will be a problem for future LSS surveys, and propose a simple recipe to account for the effect of massive neutrinos on galaxy bias.  ...  I show how cosmological data exhibits a weak preference for the normal neutrino mass ordering because of parameter space volume effects, and propose a simple method to quantify this preference.  ...  Thank you for all the energy, experience, and passion you put into training me as a scientist, for always leaving me enormous independence in pursuing my research interests and ideas, and for always pushing  ...
