Nano-Hz gravitational wave signature from axion dark matter
Naoya Kitajima, Jiro Soda, Yuko Urakawa
We calculate the accurate spectrum of the stochastic gravitational wave background from U(1) gauge fields produced by axion dark matter. The explosive production of gauge fields so…
Galaxy imaging surveys as spin-sensitive detector for cosmological colliders
Kazuhiro Kogai, Kazuyuki Akitsu, Fabian Schmidt +1
Galaxy imaging surveys provide us with information on both the galaxy distribution and their shapes. In this paper, we systematically investigate the sensitivity of galaxy shapes t…
Searching for axion-like particles under strong gravitational lenses
Aritra Basu, Jishnu Goswami, Dominik J. Schwarz +1
We establish strong gravitational lens systems as robust probes of axion-like particles (ALPs) -- a candidate for dark matter. A tiny interaction of photons with ALPs induces biref…
Can axion clumps be formed in a pre-inflationary scenario?
Hayato Fukunaga, Naoya Kitajima, Yuko Urakawa
The QCD axion and an axion-like particle (ALP) are compelling candidates of dark matter. For the QCD axion, it is known that when the Peccei-Quinn (PQ) symmetry is spontaneously br…
Constraining the gravitational coupling of axion dark matter at LIGO
Sunghoon Jung, TaeHun Kim, Jiro Soda +1
The axion-gravity Chern-Simons coupling is well motivated but is relatively weakly constrained, partly due to difficult measurements of gravity. We study the sensitivity of LIGO me…
