From Cosmic Web to Supernova Remnants: Modeling FRB DM to Trace Baryons across Multiple Scales
Zhao Joseph Zhang
Fast radio bursts (FRBs) provide a powerful probe of ionized baryons through their dispersion measures (DMs), but the observed signal contains contributions from the intergalactic…
Radio Emission from Fast Blue Optical Transients Powered by Trans-relativistic Shocks in Confined Circumstellar Material
Liang-Duan Liu, Jia-Sen Zhang, Zhao-Sheng Zhang +1
Fast blue optical transients (FBOTs) are luminous, rapidly evolving explosions whose radio emission provides a sensitive probe of shock interaction and the circumstellar material (…
Utilizing Dispersion Measure of Fast Radio Bursts to Probe the Intergalactic Medium Turbulence
Rui-Nan Li, Zhao Joseph Zhang, Kentaro Nagamine +3
Extragalactic fast radio bursts (FRBs) have emerged as powerful probes of turbulence within the intergalactic medium (IGM), a phenomenon that plays a crucial role in various cosmol…
Probing the Cosmic Baryon Distribution and the Impact of Active Galactic Nuclei Feedback with Fast Radio Bursts in CROCODILE Simulation
Zhao Joseph Zhang, Kentaro Nagamine, Yuri Oku +6
We investigate the Missing Baryon problem using Fast Radio Bursts (FRBs) to trace cosmic baryons. Our CROCODILE simulations, performed with the GADGET3/4-OSAKA smoothed particle hy…
Magnetic fields in galactic environments probed by Fast Radio Bursts
Ilya S. Khrykin, Nicolas Tejos, J. Xavier Prochaska +7
FRBs constitute a unique probe of various astrophysical and cosmological environments via their characteristic dispersion and rotation (RM) measures that encode information about t…
Signature of a magnetar central engine with precession motion in the X-ray emission of GRB 220711B
Ying-Ze Shan, Xing Yang, Hou-Jun Lü +6
The -ray light curve of long-duration GRB 220711B, is characterized by a multi-peaked structure with a duration lasting 105 seconds. More interestingly, the X-ray aftergl…
