Beyond ΛCDM with the SKA Observatory -- II: Unveiling the Secrets of the Early Universe
José Fonseca, Benedict Bahr-Kalus, Mario Ballardini +12
The origins of the universe remain one of the biggest mysteries in modern cosmology. While the Planck satellite has provided a wealth of information about the early universe, there…
Beyond ΛCDM with the SKA Observatory -- I: Probing Gravity on Cosmological Scales
S. Camera, C. Addis, S. L. Guedezounme +26
General relativity (GR) is currently the best description of the gravitational interaction at our disposal and is one of the foundations of the concordance cosmological model. For…
Impact of lensing magnification on the power spectrum turnover
Yolanda Dube, Roy Maartens, Bikash R. Dinda +2
The turnover scale of the matter power spectrum -- and consequently of the standard galaxy power spectrum monopole -- encodes a fundamental signature of matter-radiation equa…
Unbiased analysis of primordial non-Gaussianity: the multipoles of the full relativistic power spectrum
Chris Addis, Sêcloka L. Guedezounme, Jessie Hammond +5
A major goal of ongoing and future cosmological surveys of the large-scale structure is to measure local type primordial non-Gaussianity in the galaxy power spectrum through the sc…
Phantom crossing or dark interaction?
Sêcloka L. Guedezounme, Bikash R. Dinda, Roy Maartens
Recent results from DESI BAO measurements, together with Planck CMB and Pantheon+ data, suggest that there may be a `phantom' phase () in the expansion of the Univer…
Primordial non-Gaussianity -- the effects of relativistic and wide-angle corrections to the power spectrum
Sêcloka L. Guedezounme, Sheean Jolicoeur, Roy Maartens
Wide-angle and relativistic corrections to the Newtonian and flat-sky approximations are important for accurate modeling of the galaxy power spectrum of next-generation galaxy surv…
Relativistic and wide-angle corrections to galaxy power spectra
Sheean Jolicoeur, Sêcloka L. Guedezounme, Roy Maartens +3
Galaxy surveys contain information on the largest scales via wide-angle and relativistic contributions. By combining two different galaxy populations, we can suppress the strong co…
Lattice oscillator model on noncommutative space: eigenvalues problem for the perturbation theory
Dine Ousmane Samary, Sêcloka Lazare Guedezounme, Antonin Danvidé Kanfon
Harmonic oscillator in noncommutative two dimensional lattice are investigated. Using the properties of non-differential calculus and its applications to quantum mechanics, we prov…
Spherically symmetric potential in noncommutative spacetime with a compactified extra dimensions
Sêcloka Lazare Guedezounme, Antonin Danvidé Kanfon, Dine Ousmane Samary
The Schrödinger equation of the spherical symmetry quantum models such as the hydrogen atom problem seems to be analytically non-solvable in higher dimensions. When we try to compa…
Production of Dirac particle in a deformed Minkowsky space-time
Dine Ousmane Samary, Sêcloka Lazare Guedezounme, Antonin Kanfon
In this paper we study the Dirac field theory interacting with external gravitation field, described with tetrad of the form , where $\vare…
