We present the IXPE observation of GRB 221009A, which includes upper limits on the linear
polarization degree of both prompt and afterglow emission in the soft X-ray energy band. …

… IXPE instrument from GRB 221009A, accounting for the uncertainty in the measurement. Based
on IXPE … In this work we have restricted ourselves to a single source as a proof of concept…

… GRB 221009A, the highest flux gamma-ray burst (GRB) ever observed by the Fermi Gamma-ray
Burst Monitor (Fermi-GBM). This GRB … and temporal evolution of GRB 221009A. We find …

… During the IXPE observations, the rings produced by dust closer than 2 kpc were outside
the field of view, and due to the limited angular resolution and collecting area, only two rings …

… The gray shaded areas represent intervals in which GRB 221009A was not in the LAT
field of view. Note that such intervals are not displayed for times greater than T0 + 104 s. …

INTEGRAL, STIX on Solar Orbiter, IXPE… Article Views (full-text article views including HTML views…

… Placed in the global context of GRB optical afterglows, we find that the afterglow of GRB
221009A is luminous but not extraordinarily so, highlighting that some aspects of this GRB do …

… GRB 221009A happened to occur within the field of view of LHAASO, at a zenith angle of
