چکیده
We assess comprehensively the potential of galaxy cluster edges as a standard ruler in measuring cosmological distances and probing exotic physics. Confronting five alternative models with from near future Dark Energy Spectroscopic Instrument survey, we conclude that can serve promising probe to constrain beyond $\Lambda$CDM. Especially, constraining precision equation state dark energy is just about two times larger than Pantheon Type Ia supernovae sample. find power be exhibited better by combining it other probes. Combining cosmic microwave background, baryon acoustic oscillations, supernovae, chronometers simulated gravitational-wave events space-based Einstein Telescope, respectively, $\Lambda$CDM data combination background gives best constraint on Hubble constant $H_0$ $0.5\%$ matter density ratio $\Omega_m$ $1.6\%$ among these pair datasets, gravitational waves almost shares same edges. also give most stringent available data. With help probes, new insights physics at scales.

Prospects in Constraining the Dark Energy Potential
We generalize to non-flat geometries the formalism of Simon et al. (2005) to reconstruct the dark energy potential. This formalismmakes use of quantities similar to the Horizon-flow parameters in inflation, can, in principle, be made non-parametric and is general enough to be applied outside the simple, single scalar field quintessence. Since presently available and forthcoming data do not allo...
متن کاملConstraining TeVeS Gravity as Effective Dark Matter and Dark Energy
The phenomena customly described with the standard ΛCDM model are broadly reproduced by an extremely simple model in TeVeS, Bekenstein’s (2004) modification of General Relativity motivated by galaxy phenomenology. Our model can account for the acceleration of the universe seen in SNeIa distances without a cosmological constant, and the accelerations seen rotation curves of nearby spiral galaxie...
متن کاملConstraining dark energy with Sunyaev-Zel'dovich cluster surveys.
We discuss the prospects of constraining the properties of a dark energy component, with particular reference to a time varying equation of state, using future cluster surveys selected by their Sunyaev-Zel'dovich effect. We compute the number of clusters expected for a given set of cosmological parameters and propogate the errors expected from a variety of surveys. In the short term they will c...
متن کاملConstraining Born-Infeld models of dark energy with CMB anisotropies
We study the CMB constraints on two Dark Energy models described by scalar fields with different Lagrangians, namely a Klein-Gordon and a Born-Infeld field. The speed of sound of field fluctuations are different in these two theories, and therefore the predictions for CMB and structure formation are different. Employing the WMAP data on CMB, we make a likelihood analysis on a grid of theoretica...
متن کاملConstraining the coupling constant between dark energy and dark matter
We have investigated constraints on the coupling between dark matter and the interacting Chaplygin gas. Our results indicate that the coupling constant c between these two entities can take arbitrary values, which can be either positive or negative, thus giving arbitrary freedom to the inter-conversion between Chaplygin gas and dark matter. Thus, our results indicate that the restriction 0 < c ...
