Search and Characterization of Remnant Radio Galaxies in the XMM-LSS Deep Field
The Astrophysical Journal, 2023 The remnant phase of a radio galaxy is characterized by the cessation of active galactic nuclei activity, resulting in the jets ceasing to feed plasma to the radio lobes.

Scalable Two‐Step Production of High‐Efficiency Perovskite Solar Cells and Modules
Solar RRL, Volume 7, Issue 1, January 2023., 2023 The industrialization of perovskite photovoltaics requires a scalable, fully automatic, low‐cost, and high‐throughput production method to fabricate the perovskite films. This review focuses on the scalable two‐step fabrication of perovskite solar cells and modules.

FRAMEx. IV. Mechanical Feedback from the Active Galactic Nucleus in NGC 3079
The Astrophysical Journal, 2023 Using the Very Long Baseline Array, we observed the active galactic nucleus (AGN) in NGC 3079 over a span of six months to test for variability in the two main parsec-scale radio components, A and B , which lie on either side of the AGN.

The radio dichotomy of active galactic nuclei [PDF]
, 2022 The question of radio dichotomy in the active galactic nuclei (AGNs) is still in debate even it has been proposed for more than forty years. In order to solve the old riddle, we collect a sample of AGNs with optical $B$ band and radio 6cm wavelength data to analyze the radio loudness ${\rm log}R$.
