Title |
Reionization Study using GRBs | |||||
| Coauthors | ||||||||
|
Abstract |
I will review on the use of GRBs to get information for cosmic reionization, with special emphasis on the Ly alpha damping wing analysis. Recent data, especially GRB 130606A, are amazingly high in singnal-to-noise, making it possible a very high precision damping wing analysis to constrain the IGM neutral fraction. However, because of this high precision, we need to be careful for systematic uncertainties, and indeed, different groups arrived at different conclusions using the same GRB 130606A. I will examine the difference between the analysis methods and try to reveal the origin of discrepant results, and discuss future prospects for this direction. |

Title |
FRBs from Binary Neutron Star Mergers / FRB follow-up by Subaru | |||||
| Coauthors | ||||||||
|
Abstract |
I discuss the possibility of binary neutron mergers as the origin of FRBs. I will also discuss prospects of supernova/kilonova searches in optical/NIR bands in FBR error circles. Status of our FRB follow-up program by Subaru Telescope will also be reported. |
