ADVANCED STATISTICAL METHODS FOR ASTROPHYSICAL PROBES OF COSMOLOGY
/ MARCH, MARISA CRISTINA
: 2013
ABSTRACT / INHALTSTEXT
THIS THESIS EXPLORES ADVANCED BAYESIAN STATISTICAL METHODS FOR
EXTRACTING KEY INFORMATION FOR COSMOLOGICAL MODEL SELECTION, PARAMETER
INFERENCE AND FORECASTING FROM ASTROPHYSICAL OBSERVATIONS. BAYESIAN
MODEL SELECTION PROVIDES A MEASURE OF HOW GOOD MODELS IN A SET ARE
RELATIVE TO EACH OTHER - BUT WHAT IF THE BEST MODEL IS MISSING AND NOT
INCLUDED IN THE SET? BAYESIAN DOUBT IS AN APPROACH WHICH ADDRESSES THIS
PROBLEM AND SEEKS TO DELIVER AN ABSOLUTE RATHER THAN A RELATIVE MEASURE
OF HOW GOOD A MODEL IS. SUPERNOVAE TYPE IA WERE THE FIRST
ASTROPHYSICAL OBSERVATIONS TO INDICATE THE LATE TIME ACCELERATION OF THE
UNIVERSE - THIS WORK PRESENTS A DETAILED BAYESIAN HIERARCHICAL MODEL TO
INFER THE COSMOLOGICAL PARAMETERS (IN PARTICULAR DARK ENERGY) FROM
OBSERVATIONS OF THESE SUPERNOVAE TYPE IA
DIESES SCHRIFTSTUECK WURDE MASCHINELL ERZEUGT.
