A Detailed Study of Dwarf Galaxies in the Core of the Coma Cluster
Nagamani Poloji, Priya Hasan, S. N. Hasan
In an earlier paper, we determined the morphological types of galaxies in the Coma Cluster using data from the HST/ACS Coma Cluster treasury survey. We found that of the 132 member…
Membership determination in open clusters using the DBSCAN Clustering Algorithm
Mudasir Raja, Priya Hasan, Md Mahmudunnobe +2
In this paper, we apply the machine learning clustering algorithm Density Based Spatial Clustering of Applications with Noise (DBSCAN) to study the membership of stars in twelve op…
Using GMM in Open Cluster Membership: An Insight
Md Mahmudunnobe, Priya Hasan, Mudasir Raja +2
The unprecedented precision of Gaia has led to a paradigm shift in membership determination of open clusters where a variety of machine learning (ML) models can be employed. In thi…
Deep Photometry of Suspected Gravitational Lensing Events: Potential Detection of a Cosmic String
Margarita Safonova, Igor I. Bulygin, Olga S. Sazhina +3
Cosmic strings (CS) are one-dimensional cosmological-size objects predicted in realistic models of the early Universe. Analysis of the cosmic microwave background (CMB) anisotropy…
