Prediction of Star Formation Rates Using an Artificial Neural Network

Ashraf Ayubinia, Jong-hak Woo, Fatemeh Hafezianzadeh +2

In this study, we develop an artificial neural network to estimate the infrared (IR) luminosity and star formation rates (SFR) of galaxies. Our network is trained using 'true' IR l…

Identifying changing-look AGNs using variability characteristics

Shu Wang, Jong-Hak Woo, Elena Gallo +7

Changing-look (CL) Active Galactic Nuclei (AGNs), characterized by appearance/disappearance of broad emission lines in the span of a few years, present a challenge for the AGN unif…
