    Deep Neutral Hydrogen Observations of the Early-type Galaxy NGC 2768: Collided by a Newly Discovered Satellite Galaxy?

    Deep Neutral Hydrogen Observations of the Early-type Galaxy NGC 2768: Collided by a Newly Discovered Satellite Galaxy? by Nai-Ping Yu, Ming Zhu, Jin-Long Xu, Chuan-Peng Zhang, Xiao-Lan Liu, Peng Jiang

    Published 2025-01-01

    We present the results of a deep neutral hydrogen (H i ) observation of the early-type galaxy NGC 2768 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Leveraging the high sensitivity of FAST, we discover an extended gas envelope around NGC 2768. The total H i mass is measured...

    High-Pulse-Energy Topological Insulator Bi<sub>2</sub>Te<sub>3</sub>-Based Passive Q-Switched Solid-State Laser

    High-Pulse-Energy Topological Insulator Bi<sub>2</sub>Te<sub>3</sub>-Based Passive Q-Switched Solid-State Laser by Yuan-Yao Lin, Peng Lee, Jin-Long Xu, Chung-Lun Wu, Che-Min Chou, Chao-Yang Tu, Mitch M. C. Chou, Chao-Kuei Lee

    Published 2016-01-01

    Due to the ultralow saturation properties of the topological insulator (TI), stable and high-power TI-based solid state has become an important issue. In this paper, using a folding V-shaped laser cavity to minimize the residual pump to the broadband saturable absorber, passive Q-switched operations...
