🌌 New #DarkMatter Lecture! 💫 Discover #axions, learn about the #ALPS II experiment & more from the #OpenAccess @DESYnews lecture at https://enabla.com/pub/686/about 🎥

🗣 Don't be shy; ask your questions on Enabla and get answers from the lecturers themselves! Let's learn together!🤩

What is dark matter, and what are some current methods scientists are using to detect it? In this lecture, we explore the topic of this elusive substance that makes up approximately 85% of the matter in the universe. We discuss the evidence for the existence of dark matter, including gravitational lensing and the stability of galaxies, as well as the challenges in detecting it due to its lack of interaction with ordinary matter. We then focus on a particular candidate for dark matter called axions and describe an experiment aimed at detecting them using high-power lasers and strong magnets cooled to extremely low temperatures. The ALPS II experiment will significantly improve the sensitivity to a possible axion signal and could therefore provide crucial insight into the nature of dark matter. We also briefly discuss other methods for detecting dark matter, such as observing astrophysical processes. Finally, we consider the implications of dark matter for our understanding of the universe and the future directions of research in this exciting field. The lecture was given during the DESY Ukraine Winter School in February 2023.

All Enabla lectures are #free & #OpenAccess. Please support us by sharing this post, following our account & asking questions on #Enabla. Thank you!🙏

“New Horizons probe may have observed light from decaying dark matter”

The probe was able to get a view unpbstructed by the glare from Solar System dust and found that “the [cosmic optical background] is almost twice as bright as would be expected from the latest galaxy survey“

The research team “suggests that this excess light could come from the decay of axions”, a hypothetical dark matter particle.

#Axions have a double motivation: they solve the 'strong CP problem' of the #StandardModel of elementary #Particles & they are a candidate for the #DarkMatter of the #Universe. The discovery of axions would answer many questions about dark matter & other #ParticlePhysics mysteries. Axions are also predicted by #StringTheory, or the idea that all the forces & particles in the universe are tied together as part of the same framework.

Hello All. As it says in my bio:

I am a lecturer in accelerator #physics at Lancaster University, UK and at the Cockcroft Institute of Accelerator Science and Technology.

My current active projects involve:

i) Using computer simulations to study polarised particle beams as tools to measure the properties of muons, as a member of Fermilab #muon g-2.

ii) Searching for very light 'dark matter' candidates such as #axions and related 'hidden-sector' particles by exploiting the properties of electromagnetic waves in metallic and dielectric structures. In particular working on the QSHS collaboration as part of the Quantum Technologies for Fundamental Physics initiative.

iii) Designing energy-efficient, compact particle #accelerators for a range of applications including as high-flux sources of x-rays and gamma rays.
