Revisiting the distance, environment and supernova properties of SNR G57.2+0.8 that hosts SGR 1935+2154 [PDF]
Astrophysical Journal, 2020 We have performed a multi-wavelength study of supernova remnant (SNR) G57.2+0.8 and its environment. The SNR hosts the magnetar SGR 1935+2154, which emitted an extremely bright ms-duration radio burst on 2020 Apr 28 (The Chime/Frb Collaboration et al ...

A Semi-Empirical SNR Model for Soil Moisture Retrieval Using GNSS SNR Data
Remote Sensing, 2018 The Global Navigation Satellite System-Interferometry and Reflectometry (GNSS-IR) technique on soil moisture remote sensing was studied. A semi-empirical Signal-to-Noise Ratio (SNR) model was proposed as a curve-fitting model for SNR data routinely ...
