A lens model from Gaia DR3 and HST data combined with a Bayesian test on Chandra observations constrains the X-ray emission origin in lensed quasar J0659 to a 0.020 × 0.010 arcsec ellipse offset 0.014 arcsec from the optical source at 1σ.

Soft X-ray emission from SN 1987A's equatorial ring becomes broader and extends inward after ~2012, while hard X-rays remain compact, indicating growing contribution from reverse-shock-heated interior material.
CIAO is a mature, modular software system for X-ray astronomy data analysis that has supported the Chandra mission since 1999 with calibration, imaging, spectral, timing, modeling, and simulation capabilities.
