Computational Astrophysics, Data Science & AI/ML in Astronomy: A Perspective from Indian Community
Prateek Sharma, Bhargav Vaidya, Yogesh Wadadekar +7
In contemporary astronomy and astrophysics (A&A), the integration of high-performance computing (HPC), big data analytics, and artificial intelligence/machine learning (AI/ML) has…
Correlation between relativistic reflection fraction and photon index in NuSTAR sample of Seyfert 1 AGN
Savithri H. Ezhikode, Gulab C. Dewangan, Ranjeev Misra +1
The primary X-ray emission from AGN, described by a power law, irradiates the accretion disc producing reflection features in the spectrum. The reflection features arising from the…
Detection of Bars in Galaxies using a Deep Convolutional Neural Network
Sheelu Abraham, Arun Aniyan, Ajit K. Kembhavi +2
We present an automated method for the detection of bar structure in optical images of galaxies using a deep convolutional neural network which is easy to use and provides good acc…
Information Retrieval and Recommendation System for Astronomical Observatories
Nikhil Mukund, Saurabh Thakur, Sheelu Abraham +5
We present a machine learning based information retrieval system for astronomical observatories that tries to address user defined queries related to an instrument. In the modern i…
Determining the torus covering factors for a sample of type 1 AGN in the local Universe
Savithri H. Ezhikode, Poshak Gandhi, Chris Done +4
In the unified scheme of active galactic nuclei, a dusty torus absorbs and then reprocesses a fraction of the intrinsic luminosity which is emitted at longer wavelengths. Thus, sub…
Transient Classification in LIGO data using Difference Boosting Neural Network
Nikhil Mukund, Sheelu Abraham, Shivaraj Kandhasamy +2
Detection and classification of transients in data from gravitational wave detectors are crucial for efficient searches for true astrophysical events and identification of noise so…
