Latest NewsThe IXPE Caldb has been updated for the GPD (version 20260610) and XRT (version 20260609). Downloads are available from the IXPE Calibration page. Users can also access the HEASARC IXPE caldb via remote access. Delivery of data from IXPE's Detector Unit 2 (DU2) has resumed. The IXPE team performed an extensive recalibration campaign including 2.7 Ms of exposure on the bright X-ray binary Cyg X-2 in December 2025 and January 2026. The recalibration has successfully restored the polarization and spectral response of DU2. All data since the anomaly in April 2025 have been reprocessed and re-delivered with DU2. Data delivery for new observations now includes DU2. Users are encouraged to compare the results obtained with the different DUs and report any significant discrepancies via the IXPE Help Desk. For more information on the anomaly, please see this presentation by the IXPE SOC. The IXPE Caldb has been updated for the GPD (version 20260424) and XRT (version 20260331). Downloads are available from the IXPE Calibration page. Users can also access the HEASARC IXPE caldb via remote access. The IXPE project invites members of the community to join your colleagues in a monthly forum designed to inform the IXPE user community of analysis techniques and tools, programmatic announcements, and data processing and calibration updates. The meetings will be held virtually on the 3rd Thursday of each month (starting in April 2026) at 10:00 am US Central Time. Please register your interest by filling out this Google form. The 2026 Rossi Prize has been awarded to Henric Krawczynski of Washington University in St. Louis, for his contributions to the theory, instrumentation, and scientific interpretation of X-ray polarimetry. Henric has been involved in important discoveries with NASA's Imaging X-ray Polarimetry Explorer (IXPE). He has been an IXPE collaborator since selection of the mission and is first author on IXPE's first paper on stellar-mass black holes. Congratulations Henric! |
