Discerning Dark Energy Models with High-Redshift Standard Candles
Per Andersen, Jens Hjorth
Following the success of type Ia supernovae in constraining cosmologies at lower redshift , effort has been spent determining if a similarly useful standardisable can…
Efficient Resource Matching in Heterogeneous Grid Using Resource Vector
Srirangam V Addepallil, Per Andersen, George L Barnes
In this paper, a method for efficient scheduling to obtain optimum job throughput in a distributed campus grid environment is presented; Traditional job schedulers determine job sc…
Reconciling Volumetric and Individual Galaxy Type Ia Supernova Rates
Per Andersen, Jens Hjorth
Significant observational effort has been devoted to determining volumetric type Ia supernova rates at high redshifts, leading to clues about the nature of Ia supernova progenitors…
Cosmology with Peculiar Velocities: Observational Effects
Per Andersen, Tamara M. Davis, Cullan Howlett
In this paper we investigate how observational effects could possibly bias cosmological inferences from peculiar velocity measurements. Specifically, we look at how bulk flow measu…
