Survey of Gravitationally lensed Objects in HSC Imaging (SuGOHI) $-$ X. Strong Lens Finding in The HSC-SSP using Convolutional Neural Networks

Autor: Jaelani, Anton T., More, Anupreeta, Wong, Kenneth C., Inoue, Kaiki T., Chao, Dani C. -Y., Premadi, Premana W., Cañameras, Raoul

We apply a novel model based on convolutional neural networks (CNNs) to identify gravitationally-lensed galaxies in multi-band imaging of the Hyper Suprime Cam Subaru Strategic Program (HSC-SSP) Survey. The trained model is applied to a parent sample

Properties of the Environment of Galaxies in Clusters of Galaxies CL 0024+1654 and RX J0152.7-1357

Autor: Premadi, Premana W., Nugroho, Dading H., Jaelani, Anton T.

We report the results of combined analyses of X-ray and optical data of two galaxy clusters, CL 0024$+$1654 and RX J0152.7$-$1357 at redshift $z = 0.395$ and $z = 0.830$, respectively, which offer a holistic physical description of the two clusters.

Light Propagation in inhomogeneous Universes

Autor: Premadi, Premana W., Martel, Hugo, Matzner, Richard A.

Using a multi-plane lensing method that we have developed, we follow the evolution of light beams as they propagate through inhomogeneous universes. We use a P3M code to simulate the formation and evolution of large-scale structure. The resolution of
