Exploring Early Dark Energy solution to the Hubble tension with Planck and SPTPol data
Anton Chudaykin, Dmitry Gorbunov, Nikita Nedelko
A promising idea to resolve the long standing Hubble tension is to postulate a new subdominant dark-energy-like component in the pre-recombination Universe which is traditionally t…
Optimizing large-scale structure data analysis with the theoretical error likelihood
Anton Chudaykin, Mikhail M. Ivanov, Marko Simonović
An important aspect of large-scale structure data analysis is the presence of non-negligible theoretical uncertainties, which become increasingly important on small scales. We show…
Constraints on the curvature of the Universe and dynamical dark energy from the Full-shape and BAO data
Anton Chudaykin, Konstantin Dolgikh, Mikhail M. Ivanov
We present limits on the parameters of the oCDM, CDM, and CDM models obtained from the joint analysis of the full-shape, baryon acoustic oscillations (BAO), big ba…
Cosmology Intertwined IV: The Age of the Universe and its Curvature
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +88
A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in…
Cosmology Intertwined III: and
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89
The standard Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with t…
Cosmology Intertwined II: The Hubble Constant Tension
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +90
The current cosmological probes have provided a fantastic confirmation of the standard Cold Dark Matter cosmological model, that has been constrained with unprecedented accurac…
Cosmology Intertwined I: Perspectives for the Next Decade
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89
The standard Cold Dark Matter cosmological model provides an amazing description of a wide range of astrophysical and astronomical data. However, there are a few big open quest…
Combined analysis of Planck and SPTPol data favors the early dark energy models
Anton Chudaykin, Dmitry Gorbunov, Nikita Nedelko
We study the implications of the Planck temperature power spectrum at low multipoles, , and SPTPol data. We show that this combination predicts consistent lensing-induce…
Non-linear perturbation theory extension of the Boltzmann code CLASS
Anton Chudaykin, Mikhail M. Ivanov, Oliver H. E. Philcox +1
We present a new open-source code that calculates one-loop power auto- and cross-power spectra for matter fields and biased tracers in real and redshift space. These spectra incorp…
