Inferring the Hubble Constant Using Simulated Strongly Lensed Supernovae and Neural Network Ensembles
Gonçalo Gonçalves, Nikki Arendse, Doogesh Kodi Ramanah +1
Strongly lensed supernovae are a promising new probe to obtain independent measurements of the Hubble constant (). In this work, we employ simulated gravitationally lensed T…

AI-driven spatio-temporal engine for finding gravitationally lensed type Ia supernovae
Doogesh Kodi Ramanah, Nikki Arendse, Radosław Wojtak
We present a spatio-temporal AI framework that concurrently exploits both the spatial and time-variable features of gravitationally lensed supernovae in optical images to ultimatel…
