Classification of Wolf Rayet stars using Ensemble-based Machine Learning algorithms
Subhajit Kar, Rajorshi Bhattacharya, Ramkrishna Das +2
We develop a robust Machine Learning classifier model utilizing the eXtreme-Gradient Boosting (XGB) algorithm for improved classification of Galactic Wolf-Rayet (WR) stars based on…
Gravitational wave: generation and detection techniques
Saibal Ray, R. Bhattacharya, Sanjay K. Sahay +2
In this paper, we review the theoretical basis for generation of gravitational waves and the detection techniques used to detect a gravitational wave. To materialize this goal in a…
Long-period maser-bearing Miras in the Galactic center: period-luminosity relations and extinction estimates
M. O. Lewis, R. Bhattacharya, L. O. Sjouwerman +5
We establish a sample of 370 Mira variables that are likely near the Galactic center (GC). The sources have been selected from the OGLE and BAaDE surveys based on their sky coordin…
