Design and preliminary performance study of the broad-band spectrometer detector for POLAR-2
Jian-Chao Sun, Jiang He, Shuang-Nan Zhang +46
POLAR-2, the successor of the POLAR experiment aboard China's Tiangong-2 space lab, is set to be deployed on the China Space Station. The POLAR-2 mission aims to conducting high-pr…
Prospects of Prompt Gamma-Ray Burst Polarimetry with POLAR-2
Ramandeep Gill, Jiang He, Jonathan Granot +6
The dominant radiation mechanism that powers the prompt -ray emission in gamma-ray bursts (GRBs) remains poorly understood. High quality, time- and energy-resolved linear polar…
Probing Stellar Kinematics with the Time-Asymmetric Hanbury Brown and Twiss Effect
Lucijana Stanic, Ivan Cardea, Edoardo Charbon +11
Intensity interferometry (II) offers a powerful means to observe stellar objects with a high resolution. In this work, we demonstrate that II can also probe internal stellar kinema…
Exploiting light coherence in astrophysics
Vitalii Sliusar, Domenico Della Volpe, Benjamin Garcia +7
The Hanbury Brown-Twiss (HBT) effect, discovered in the 1950s and further developed in the 1960s, was originally used to estimate stellar angular diameters through intensity correl…
Stellar physics at sub-nanoradian angular resolution
P. Batista, J. Biteau, C. Carlile +36
Many stars -- if they could be imaged with enough angular resolution -- would exhibit features expected from theory but not possible to extract from spectra. We may group these by…
POLAR-2 -- Latest Developments of the Next Generation GRB Polarimeter
Johannes Hulsman, Philipp Azzarello, Joerg Bayer +20
Gamma-Ray Bursts (GRBs) are among the most energetic events in the Universe. Despite over 50 years of research and measurements their prompt emission remains poorly understood, wit…
