Projected distances to host galaxy reduce SNIa dispersion
R. Hill, H. Shariff, R. Trotta +8
We use multi-band imagery data from the Sloan Digital Sky Survey (SDSS) to measure projected distances of 302 supernova type Ia (SNIa) from the centre of their host galaxies, norma…
The Type Ia Supernova Color-Magnitude Relation and Host Galaxy Dust: A Simple Hierarchical Bayesian Model
Kaisey S. Mandel, Daniel Scolnic, Hikmatali Shariff +2
Conventional Type Ia supernova (SN Ia) cosmology analyses currently use a simplistic linear regression of magnitude versus color and light curve shape, which does not model intrins…
Standardizing Type Ia supernovae using Near Infrared rebrightening time
Hikmatali Shariff, Suhail Dhawan, Xiyun Jiao +3
Accurate standardisation of Type Ia supernovae (SNIa) is instrumental to the usage of SNIa as distance indicators. We analyse a homogeneous sample of 22 low-z SNIa, observed by the…
BAHAMAS: new SNIa analysis reveals inconsistencies with standard cosmology
H. Shariff, X. Jiao, R. Trotta +1
We present results obtained by applying our BAyesian HierArchical Modeling for the Analysis of Supernova cosmology (BAHAMAS) software package to the 740 spectroscopically confirmed…
