A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

The Review summarizes much of particle physics and cosmology. Using data from previous
editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average …

Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

Dark sector, constituting about 95% of the Universe, remains the subject of numerous
studies. There are lots of models dealing with the cause of the effects assigned to “dark …

Long range scalar fields with a coupling to matter appear to violate known bounds on
gravitation in the solar system and the laboratory. This is evaded thanks to screening …

We explore the prospects for direct detection of dark energy by current and upcoming
terrestrial dark matter direct detection experiments. If dark energy is driven by a new light …

We present the first hydrodynamical cosmological simulations in the νHDM framework
based on Milgromian dynamics (MOND) with light (11 eV) sterile neutrinos. νHDM can …

The first multi-messenger gravitational wave event has had a transformative effect on the
space of modified gravity models. In this paper we study the enhanced tests of gravity that …

We use gravitational wave (GW) standard sirens, in addition to Type Ia supernovae (SNIa)
and baryon acoustic oscillation (BAO) mock data, to forecast constraints on the …
