ROGer: Remote Observing from Greenland
On demand | Presented live 18 June 2024 
Abstract
Magnetic field (B-field) is the most controversial factor in molecular clouds for star formation, necessitating further observations. The Star Formation Group at the Chinese University of Hong Kong is currently engaged in the construction of ROGer, Asia's inaugural polarimetry. ROGer will be installed on the 12-meter Greenland Telescope (GLT) and will facilitate the observation of B-field morphology within molecular clouds by utilizing dust thermal emission at 345 GHz. ROGer's polarization module introduces the novel implementation of Martin-Puplett interferometer (MPI) optics, enabling real-time sky noise elimination on the same detector through destructive interference. Two 157-pixel silicon-based aluminum film Microwave Kinetic Inductance Detector (MKID) arrays will be employed to detect the orthogonal signal from the MPI optics. Here we will present the prototype of our novel MPI polarimetry and optics design.

Weitao LYU was born in Hubei, China. He obtained his Bachelor's degree in Physics from Huazhong University of Science and Technology in Wuhan, China, in June 2015. Subsequently, he pursued his passion for astrophysics and earned his Ph.D. degree from the University of Science and Technology of China in September 2021. During his doctoral studies, he focused on the design and performance characterization of superconducting Microwave Kinetic Inductance Detectors (MKIDs). Since September 2021, he has been engaged in postdoctoral research at the Chinese University of Hong Kong. His primary research area involves the characterization and integration of MKIDs for the ROGer project, with a specific focus on camera systems.
