Anisotropies in Cosmological 21 cm Background by Oscillons/I-balls of Ultra-light Axion-like Particle
Masahiro Kawasaki, Kazuyoshi Miyazaki, Kai Murai +2
Ultra-light axion-like particle (ULAP) with mass has recently been attracting attention as a possible solution to the small-scale crisis. ULAP forms…
Probing Oscillons of Ultra-Light Axion-like Particle by 21cm Forest
Masahiro Kawasaki, Wakutaka Nakano, Hiromasa Nakatsuka +1
Ultra-Light Axion-like Particle (ULAP) is motivated as one of the solutions to the small scale problems in astrophysics. When such a scalar particle oscillates with an $\mathcal{O}…
Oscillons of Axion-Like Particle: Mass distribution and power spectrum
Masahiro Kawasaki, Wakutaka Nakano, Hiromasa Nakatsuka +1
In string theory, the simultaneous existence of many Axion-Like Particles (ALPs) are suggested over a vast mass range, and a variety of potentials have been developed in the contex…
Oscillon of Ultra-Light Axion-like Particle
Masahiro Kawasaki, Wakutaka Nakano, Eisuke Sonomoto
Ultra-light axion-like particle (ULAP) is one of attractive candidates for cold dark matter. Because the de Broglie wavelength of ULAP with mass is $\mathc…
