2nd UNDARK Workshop on Astrophysical searches of dark sectors with gamma-ray observations: 28th September to 2nd October, 2026

This is the 2nd UNDARK workshop, was held in the  Instituto de Astrofísica de Canarias  (IAC) during 28 September - 2 October 2026. This workshop focus on astrophysical probes of fundamental questions related to the dark universe, with a specific emphasis on gamma-ray observations and the high-energy Universe. The meeting is organized in the context of the  UNDARK  project and it aligns with the observational and instrumental expertise of the IAC in high-energy astrophysics, including experiments such as CTAO, ASTRI, MAGIC or AMS.

Topics of Discussion

The workshop covers a range of cutting-edge topics in gamma-ray astronomy and their implications for dark sector physics, including:

  • Observational overview from MeV to PeV

  • Dark matter indirect probes through photons from MeV to PeV

  • Multi-messenger probes of dark matter

  • Machine-learning and data analysis challenges with gamma-ray observations

This workshop aims to bring together leading researchers in gamma-ray astronomy, astrophysics, and particle physics to discuss recent advancements, ongoing projects, and future directions in the search for the dark sector of the universe.

This is the 1st UNDARK workshop, was held in the  Instituto de Astrofísica de Canarias  (IAC) during 29 September - 3 October 2025. This workshop focused on astrophysical probes of fundamental questions related to the dark universe, with a specific emphasis on radio wave observations, as well as their possible connections with gravitational wave detection. The meeting is organized in the context of the  UNDARK project and it aligns with the observational and instrumental expertise of the IAC in microwave astronomy, including experiments such as QUIJOTE, TMS, LSPE-STRIP, and GroundBIRD.
