Identification of dark matter has been an outstanding problem for decades, and axion (or axion like particles) is one of the most popular dark matter candidates. A number of observations and experiments have tried to detect axion by using the axion-photon conversion by assuming the axion is coupled to photon, while no signal yet to be found. In this talk, I will discuss new techniques to...

2. Dark Matter, First Light

Dark matter forms the foundation for all cosmic structure, and its fundamental nature is one of science's most pressing enigmas. As we search for the most distant galaxies in the universe with radio and infrared observations, we are in a position to explore the particle physics of dark matter — the possibility of annihilation, decay, or other particle interactions — through its effects on...

3. Why we should stop talking about the expansion of space

Pierre Fleury

A popular stand about the interpretation of cosmic expansion is the following: « […] expansion redshift are produced by the expansion of space between bodies that are stationary in space. » [Harrison (2000)]. Most of us have been taught cosmology that way, and we naturally tend to replicate this message, notably in public outreach—think of the ubiquitous analogy of the inflating balloon. The...
