Over the past decade or so, DESY's Photon Science Detector group has spearheaded a number of developments - motivated by the dire need for faster large-area imagers with high dynamic range that is a direct consequence of the advances in synchrotron light sources and free electron lasers.

The Any Light Particle Search II (ALPS II) experiment at DESY will look for axion-like particles (ALPs) with low masses ($m<10^{-4}$ eV). ALPS II is a purely laboratory-based experiment, where ALPs could be produced and detected employing the light-shining-through-wall (LSW) technique using infrared photons with a wavelength of 1064 nm. ALPS II utilizes the concept of resonant enhancement on...

In well-motivated extensions of the Standard Model to solve the strong CP problem of quantum chromodynamics, axions emerge as leading candidates of non-WIMP dark matter. In this seminar, we discuss tabletop-scale experiments in axion detection, particularly focusing on new observables for direct detection of axion dark matter. For instance, axion interactions with electrons in condensed matter...

Gamma ray and/or neutron spectrometers have been flown on planetary spaceflight missions since the USSR’s Luna-10 mission first used a gamma ray spectrometer to study the composition of the Moon from lunar orbit. Due to nuclear interactions with galactic cosmic rays (or a separate source of high energy neutrons), planetary materials emit gamma rays and neutrons that can be measured to...

Gravitational waves are a hot topic, after their first detection by the LIGO observatories in 2015 and the nobel prize award in 2017.

While the success story of the ground based detectors continues, the scientific community is busy preparing the next steps in gravitational wave observation. One of these next steps is launching a space based gravitational wave observatory: LISA, the “Laser...
