LemaîtreTolmanBondi inhomogeneous spacetimes are used as a cosmological model for type Ia supernova data. It is found that with certain parameter choices the model fits the data as well ...
-squares fitting procedure, we model the observations of type Ia SN rates assuming different combinations of three recent cosmic star formation rates and seven delay time distributions. The goodness ...
ABSTRACT Recently, the common methodology used to transform Type Ia supernovae (SNe Ia ) into genuine standard candles has been suffering criticism. Indeed, it assumes a particular cosmological model ...
of constraining dark energy model from the distance modulus of type Ia supernovae . 4.1 Distance modulus and dark energy Distance modulus of SN Ia can be used as the probe of the cosmological model . The distance ...
From a phenomenological point of view , we analyze the dynamics of the Universe at late times by introducing a polynomial and hyperbolic bulk viscosity into the Einstein field equations respectively ...
Abstract Umberto Battino and Alex Murphy consider both key observables of Type Ia supernovae and computational modelling of progenitor evolution and explosion, as discussed at an RAS meeting 1 Open ...
spectrograph and its applications to Type Ia supernova cosmology . In the slicer IFU spectrograph, the sky image is focused on a segmented (sliced) mirror. Each slice is tilted to reflect the section of the sky ...
possible biases from selection effects, we use the SDSS-II (Frieman et al. 2008) and Supernova Legacy Survey (SNLS) (Astier et al. 2006) SN Ia samples, whose selection effects are well modelled with Monte ...
models , see for instance Maartens 2004, or Maartens 2000, for a cosmological point of view ). Another alternative interpretation is to consider a fluid (that may or may not be in an intrinsically 4D metric ...
with results based on volumetric rates of type Ia supernovae at high redshift. The model is tested against realistic star formation rates from the Illustris-1 simulation and is found to be self-consistent ...
