Does the Amati Correlation Exhibit Redshift-Driven Heterogeneity in Long GRBs?

Darshan Singh, Meghendra Singh, Dinkar Verma +2

Long gamma-ray bursts (GRBs) offer significant insights into cosmology due to their high energy emissions and the potential to probe the early universe. The Amati relation, which l…

Investigating the Evolution of Amati Parameters with Redshift

Meghendra Singh, Darshan Singh, Kanhaiya Lal Pandey +2

Gamma Ray Bursts (GRB) are among the brightest objects in the Universe and hence can be observed up to a very high redshift. Properly calibrated empirical correlations between inte…

Cosmological Analysis using Panstarrs data: Hubble Constant and Direction Dependence

Rahul Kumar Thakur, Meghendra Singh, Shashikant Gupta +1

Hubble tension and the search for preferred direction are two crucial unresolved issues in modern cosmology. Different measurements of the Hubble constant provide significantly dif…

On The Non-Gaussian Errors in High-z Supernovae Type Ia Data

Meghendra Singh, Ashwini Pandey, Amit Sharma +2

The nature of random errors in any data set that is Gaussian is a well established fact according to the Central Limit Theorem. Supernovae type Ia data have played a crucial role i…

Measurement of Hubble constant: Non-Gaussian Errors in HST key project data

Meghendra Singh, Shashikant Gupta, Ashwini Pandey +1

Assuming the Central Limit Theorem, experimental uncertainties in any data set are expected to follow the Gaussian distribution with zero mean. We propose an elegant method based o…

High-z Supernova Type Ia Data: non-Gaussianity and Direction Dependence

Shashikant Gupta, Meghendra Singh

We use the statistic introduced in \cite{gup08,gup10} to study directional dependence, in the high-z supernovae data. This dependence could arise due to departures from t…
