Measurements of secondary cosmic microwave background (CMB) anisotropies, such as the Sunyaev-Zel'dovich (SZ) effect, will enable new tests neutrino and dark sector properties. The kinetic SZ (kSZ) effect is produced by cosmological flows, probing structure growth. Ultra-light axions (ULAs) are a well-motivated dark-matter candidate. Here impact ULA matter (with mass $10^{-27}~{\rm eV}$ to $10^...

Abstract We consider the use of quantum-limited mechanical force sensors to detect ultralight (sub-meV) dark matter (DM) candidates which are weakly coupled standard model. show that with masses around or below milligram scale, operating quantum limit, would enable novel searches for DM natural frequencies kHz scale. This complement existing strategies based on torsion balances, atom interferom...

In this work, we study the propagation of high energy neutrinos produced in extragalactic sources including effect a possible interaction with ultralight axion-like particles (UALP) mass $m_a\sim 10^{-22} {\rm eV}$ as constituents dark matter (DM) under assumption that their coupling to is dominant. We compute cross section and describe diffuse neutrino flux using transport equations for each e...

If ultralight $(\ll$ eV), bosonic dark matter couples to right handed neutrinos, active neutrino masses and mixing angles depend on the ambient density. When Majorana mass, induced by background, is small compared Dirac neutrinos are "pseudo-Dirac" fermions that undergo oscillations between nearly degenerate sterile states. We present a complete cosmological history for such scenario find sever...

Carbon-based aerogels, composed of interconnected threedimensional (3D) networks, have attracted intensive attention because of their unique physical properties, such as low density, high electrical conductivity, porosity, and specific surface area. As a result, carbon-based aerogels are promising materials used as catalyst supports, artificial muscles, electrodes for supercapacitors, absorbent...
