The DrizzlePac package includes tasks for aligning and drizzling images taken with the Hubble Space Telescope. We present this release which includes new features that facilitate image alignment, sky matching, and adds support for new time dependent distortion solutions of the ACS instrument. The TweakReg task now includes capabilities for automatically aligning images which form part of a mosaic. In addition, new parameters make it easier to reject cosmic rays and other spurious detections from source catalogs used for alignment. The Astrodrizzle task has been improved with a new sky matching algorithm which makes producing mosaics easier than ever before. This new version supports an improved version of the ACS/WFC time-dependent distortion correction. There are also improvements to the GUI interfaces and some behind the scene bug fixes.

  1. GRB 210704A: A Luminous Fast Blue Transient in a GRB Afterglow at $z = 2.34$

    astro-ph.HE 2026-04 unverdicted novelty 6.0

    GRB 210704A at z=2.34 shows a luminous fast blue transient excess peaking at ~7 days, modeled as refreshed shock emission and linked to LFBOTs alongside a high-Lorentz-factor jet.
