Projects

Talking Planets- Astronomy Educational App Development

Awarded Astronomy for Development Grants funded by Office of Astronomy for Development of the International Astronomical Union for this astronomy education related project. I am the leader and project coordinator of this project. You can download our developed app by following this link- https://play.google.com/store/apps/details?id=app.talking.planets. It’s an android application with 12 characters (8 planets of our solar system, Sun, our Moon, Europa, and IO). A user can chat with these characters to know their mass, temperature, size, type, sky color, etc. The characters will behave like chatbots with the user.

Classification of Galaxies, Stars, and Quasars from Sloan Digital Sky Survey Data Release 17 Using Different Machine Learning Techniques

We worked with a specific chunk of data from Sloan Digital Sky Survey data release 17. Using machine learning models, we aimed to accurately classify stars, galaxies, and quasars (QSO). We applied a total of 15 different machine learning models to our dataset and then applied a voting classifier as an ensemble technique. Finally, we were able to increase our classification accuracy to 98.36%. We also compared some key differences of our research with a previous study on the same dataset, which had an accuracy of 98%.

BD And- a Detached System and Photometric LCs

A group project of the 42nd International School for Young Astronomers. We have done a photometric analysis of EA type eclipsing binary system (BD And)
