Axion is a light particle arising in QCD as a solution to the strong CP problem and is considered to be one of the most promising dark matter candidate with interesting astrophysical and cosmological implications. At first, I will outline the scheme and sensitivity of a novel radio probe, axion gegenschein, in which axion-like particles undergo stimulated decay into photons creating a countersource in a direction opposite to an astrophysical source. In the second part of the talk, I will describe the design and sensitivity of the cutting-edge axion detector, the Weakly Interacting Slender Particle detection with LC circuit (WISPLC), which will look for axion-like particles in a wide range of masses set to operate in broadband and resonant modes.Axion is a light particle arising in QCD as a solution to the strong CP problem and is considered to be one of the most promising dark matter candidate with interesting astrophysical and cosmological implications.
