Estimation of the Coefficient of Variation of Weibull Distribution under Type-I Progressively Interval Censoring: A Simulation-based Approach
Bankitdor M Nongrum, Adarsha Kumar Jena
Measures of relative variability, such as the Pearson's coefficient of variation (CV), give much insight into the spread of lifetime distributions, like the Weibull distributio…
Axion-Photon Conversion In Magnetized Universe: Impact On The Global 21-cm Signal
Pravin Kumar Natwariya, Vivekanand Mohapatra, Hriditi Howlader
The reported anomalous global 21-cm signal from the cosmic dawn era by Experiment to Detect the Global Epoch of Reionisation Signature (EDGES) could hint towards new phy…
Cosmological bounds on dark matter annihilation using dark ages 21-cm signal
Vivekanand Mohapatra
We investigate the impact of dark matter (DM) annihilation on the global 21-cm signal during the dark ages and cosmic dawn eras. The 21-cm line provides a complementary probe for s…
WaveCatBoost for Probabilistic Forecasting of Regional Air Quality Data
Jintu Borah, Tanujit Chakraborty, Md. Shahrul Md. Nadzir +2
Accurate and reliable air quality forecasting is essential for protecting public health, sustainable development, pollution control, and enhanced urban planning. This letter presen…
Primordial Magnetic Fields in Light of Dark Ages Global 21-cm Signal
Vivekanand Mohapatra, Pravin Kumar Natwariya, Alekha C. Nayak
We study the constraints on primordial magnetic fields (PMFs) in light of the global 21-cm signal observed during the dark ages. Primordial magnetic fields can heat the intergalact…
In Search of Global 21-cm Signal using Artificial Neural Network in light of ARCADE 2
Vivekanand Mohapatra, Johnny J, Pravin Kumar Natwariya +2
Understanding the astrophysical nature of the first stars remains an unsolved problem in cosmology. The redshifted global 21-cm signal acts as a treasure trove to prob…
