We present MOND analysis for several of the lowest mass disc galaxies currently amenable to such analysis–with (baryonic) masses below 4 · 108M⊙. The agreement is good, extending the validity of MOND and its predicted mass velocity relation, to such low masses. Subject headings: dark matter galaxies: kinematics and dynamics

Bound quantum mechanical systems not expanding with the comoving frame of an expanding, flat FRW metric are found to release energy at a rate linearly proportional to the local Hubble constant (H o) and the systems' binding energy (E b); i.e., ˙ E = H o E b. Three exemplary quantum systems are examined. For systems with early cosmological condensation times — notably hadrons — time-integrated e...

The axion solution of the strong CP problem provides a number of possible windows to physics beyond the standard model, notably in the form of searches for solar axions and for galactic axion dark matter, but in a broader context also inspires searches for axion-like particles in pure laboratory experiments. We briefly review the motivation for axions, astrophysical limits, their possible cosmo...
