DESCRIPTION:[b]Speaker: Manuel Meyer [/b] [nl]\nDepartment of Physics\, Ch
 emistry and Pharmacy[nl]\nUniversity of Southern Denmark [nl][nl]\n[b]Abs
 tract:[/b][nl]\nThe nature of dark matter continues to elude us\, even af
 ter almost one century after first evidence for this non-luminous substan
 ce appeared. A leading hypothesis is that dark matter\, which makes up mo
 re than 80% of all matter in the universe\, consists of yet undiscovered 
 fundamental particles. Such dark matter particles might interact feebly w
 ith known particles of the Standard Model\, making them potentially detec
 table in the laboratory. The predicted low interaction rates require extr
 emely sensitive detectors and ultra-low background levels. In this talk\,
  I will discuss our recent progress in characterizing and improving the p
 erformance of transition edge sensors (TESs). Such TESs are planned to be
  used in the Any Light Particle (ALPS) II experiment\, which searches for
  axions and axion-like particles. I will also review how we can use our T
 ES to search for weakly interacting massive particles. With our ongoing r
 esearch\, we hope to achieve a new record for background suppression empl
 oying both optical filtering inside a cryostat as well as machine learnin
 g techniques while maintaining a quantum efficiency close to unity. \n[nl
