Across the soft gamma-ray regime: utilizing simultaneous detections in the Compton Spectrometer and Imager (COSI) and the Background and Transient Observer (BTO) to understand astrophysical transients

Posted by dbos Tokyo

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hannah C. Gulick, Eliza Neights, Samer Al Nussirat, Claire Tianyi Chen, Kaylie Ching | Summary: The Compton Spectrometer and Imager (COSI) is a NASA funded Small Explorer (SMEX) mission slated to launch in 2027. COSI will house a wide-field gamma-ray telescope designed to survey the entire sky […]

RIS-Assisted Received Adaptive Spatial Modulation for Wireless Communication

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Chaorong Zhang, Hui Xu, Benjamin K. Ng, Chan-Tong Lam, Ke Wang | Summary: A novel wireless transmission scheme, as named the reconfigurable intelligent surface (RIS)-assisted received adaptive spatial modulation (RASM) scheme, is proposed in this paper. In this scheme, the adaptive spatial modulation (ASM)-based antennas selection works […]

Investigating the interplay between AGN coronal properties and hard X-ray variability with NuSTAR

Posted by dbos Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Roberto Serafinelli, Alessandra De Rosa, Alessia Tortosa, Luigi Stella, Fausto Vagnetti | Summary: Active galactic nuclei (AGN) are extremely variable in the X-ray band down to very short time scales. However, the driver of the X-ray variability is still poorly understood. Previous results suggest that the hot […]
