Mimetic Gravity: A Review of Recent Developments and Applications to Cosmology and Astrophysics by Lorenzo Sebastiani, Sunny Vagnozzi, Ratbay Myrzakulov

“…Mimetic gravity is a Weyl-symmetric extension of General Relativity, related to the latter by a singular disformal transformation, wherein the appearance of a dust-like perfect fluid can mimic cold dark matter at a cosmological level. Within this framework, it is possible to provide a unified geometrical explanation for dark matter, the late-time acceleration, and inflation, making it a very attractive theory. …”

Smooth Crossing of wΛ=−1 Line in a Single Scalar Field Model by Abhik Kumar Sanyal

“…Smooth double crossing of the phantom divide line wΛ=−1 has been found possible with a single minimally coupled scalar field for the most simple form of generalized k-essence cosmological model, in the presence of background cold dark matter. Such crossing is a sufficiently late time transient phenomenon and does not have any pathological behaviour.…”

Dynamics of Mixed Dark Energy Domination in Teleparallel Gravity and Phase-Space Analysis by Emre Dil, Erdinç Kolay

“…Here we propose a mixed dark energy domination which is constituted by tachyon, quintessence, and phantom scalar fields nonminimally coupled to gravity, in the absence of background dark matter and baryonic matter, in the framework of teleparallel gravity. …”

Relative measurement and extrapolation of the scintillation quenching factor of $$\alpha $$ α -particles in liquid argon using DEAP-3600 data by DEAP Collaboration

“…Abstract The knowledge of scintillation quenching of $$\alpha $$ α -particles plays a paramount role in understanding $$\alpha $$ α -induced backgrounds and improving the sensitivity of liquid argon-based direct detection of dark matter experiments. We performed a relative measurement of scintillation quenching in the MeV energy region using radioactive isotopes ( $$^{222}$$ 222 Rn, $$^{218}$$ 218 Po and $$^{214}$$ 214 Po isotopes) present in trace amounts in the DEAP-3600 detector and quantified the uncertainty of extrapolating the quenching factor to the low-energy region.…”

What Remains to Be Discovered? by Pavel Nováček

“…Among the most promising challenges on the border between science and our imaginations, is an exploration of our universe, and potential contact with an extra-terrestrial civilisation, better understanding of space, time, matter, and energy (including “dark matter” and “dark energy”) and, of course, the “unthinkable” potential of the human brain. …”

Dark Energy in Spherically Symmetric Universe Coupled with Brans-Dicke Scalar Field by Koijam Manihar Singh, Gauranga C. Samanta

“…Here, it is seen that the dark energy triggers the big bang and after that much of the dark energy reduces to dark matter. One peculiarity in such a model is that the scalar field is prevalent eternally; it never tends to zero.…”

Curvature-Restored Gauge Invariance and Ultraviolet Naturalness by Durmuş Ali Demir

“…Gravity arises correctly if new physics exists with at least 63 more bosons than fermions, with no need to interact with the SM and with dark matter as a natural harbinger. It can source various cosmological, astrophysical, and collider phenomena depending on its spectrum and couplings to the SM.…”

The Transcribed-Ultraconserved Regions: A Novel Class of Long Noncoding RNAs Involved in Cancer Susceptibility by Paola Scaruffi

“…A large proportion of the transcriptional output is represented by protein noncoding RNAs (ncRNAs) that arise from the “dark matter” of the genome. Focus on such sequences has revealed numerous RNA subtypes with several functions in RNA processing and gene expression regulation, and deep sequencing studies imply that many remain to be discovered. …”
