Ultralight axion like particles (ALPs) of mass ma ∈ (10−21eV − 10−22eV) with axion decay constant fa ∼ 1017GeV can be candidates for fuzzy dark matter (FDM). If celestial bodies like Earth and Sun are immersed in a low mass axionic FDM potential and if the ALPs have coupling with nucleons then the coherent oscillation of the axionic field results a long range axion hair outside of the celestial bodies. The range of the axion mediated Yukawa type fifth force is determined by the distance between…

Constraints on the mass and self-coupling of ultra-light scalar field dark matter using observational limits on galactic central mass

It is well known that Ultra-Light Dark Matter (ULDM), usually scalar fields of mass m ∼ 10-22 eV, can solve some of the outstanding problems of the Cold Dark Matter (CDM) paradigm. Such a scalar

Constraints on ultralight axions from compact binary systems

Ultra light particles $(m_a \sim 10^{-21}eV-10^{-22}eV)$ with axion-like couplings to other particles can be candidates for fuzzy dark matter (FDM) if the axion decay constant $f_a\sim 10^{17}GeV$.

Dark matter axions revisited

We study for what specific values of the theoretical parameters the axion can form the totality of cold dark matter. We examine the allowed axion parameter region in the light of recent data

First Constraints on Fuzzy Dark Matter from Lyman-α Forest Data and Hydrodynamical Simulations.

Light boson masses in the range 1-10×10^{-22}  eV are ruled out at high significance by the analysis, casting strong doubts that FDM helps solve the "small scale crisis" of the cold dark matter models.

Detecting axionlike dark matter with linearly polarized pulsar light

Non-relativistic QCD axions or axion-like particles are among the most popular candidates for cold Dark Matter (DM) in the universe. We proposed to detect axion-like DM, using linearly polarized

Axions as dark matter particles

We overview the current status of axions as dark matter. The axion is the pseudo-Nambu–Goldstone boson which arises from the Peccei–Quinn solution to the strong CP problem. Additionally, cold axion
