6. Development of Position Sensitive Deep Transient Spectroscopy as a background mitigation tool for CCD-based dark matter searches

Dr Vagelis Gkougkousis (University of Zurich)

01/07/2025, 11:30

The unparalleled sensitivity achieved with skipper CCDs, coupled with ultra-pure high-resistivity substrates (>22 kOhm×cm) and cryogenic operation, has rekindled interest in this technology for low-background experiments (DAMIC@SNOLAB, DAMIC-M, SENSEI, and OSCURA) Such devices offer sub-electron noise resolution, enabling the detection of extremely low-energy interactions critical for...

21. Constraining Dark Matter with Stellar Objects

Dr Ioannis Dalianis (University of Cyprus)

01/07/2025, 12:00

Stellar objects provide a unique and powerful laboratory for probing the properties of dark matter. In this talk, I will focus on how the accumulation and annihilation of dark matter can influence stellar evolution, luminosity, and stability. I will present constraints on dark matter particle mass and interactions which offer complementary limits to those derived from cosmological observations...
