Abstract: A bstractThe cold dark matter (CDM) scenario has proved successful in cosmology. However, we lack a fundamental understanding of its microscopic nature. Moreover, the apparent disagreement between CDM predictions and subgalactic-structure observations has prompted the… read more here.

DOI: 10.1051/0004-6361/202040239
Abstract: Aims. We use stellar line-of-sight velocities to constrain the dark matter-density profile of Eridanus 2, an ultra-faint dwarf galaxy ($M_\mathrm{V} = -7.1$, $M_* \approx 9 \times 10^4\,M_\odot$). We furthermore derive constraints on fundamental properties of… read more here.

DOI: 10.1088/1475-7516/2021/09/041
Abstract: Ultralight axion like particles (ALPs) of mass m_a∈ (10-21 eV–10-22 eV) with axion decay constant fa∼ 1017 GeV can be candidates for fuzzy dark matter (FDM). If celestial bodies like Earth and Sun are immersed… read more here.

DOI: 10.1103/physrevd.98.065015
Abstract: It has been suggested that dark matter is a superfluid of particles whose masses are on the rough order of $10^{-22}$ eV. Since the occupation numbers are huge, the state is coherent, and the speeds… read more here.
