Description
LHAASO first detected the onset phase of the TeV afterglow from GRB221009A and observed its
temporal overlap with the prompt emission phase, thereby offering an opportunity to detect or
constrain radiation associated with rapid variability components resembling the TeV prompt
emission in the afterglow background. The detection of TeV prompt emission could open a new
window for theoretical research on GRBs. Using data from LHAASO-WCDA, we detected potential
rapid variability components associated with the prompt emission in the afterglow of GRB221009A
at a significance level of approximately 4σ.
