Non-Gaussianity and the Cosmic Microwave Background Anisotropies by N. Bartolo, S. Matarrese, A. Riotto

“…We review in a pedagogical way the present status of the impact of non-Gaussianity (NG) on the cosmic microwave background (CMB) anisotropies. We first show how to set the initial conditions at second order for the CMB anisotropies when some primordial NG is present. …”

5σ tension between Planck cosmic microwave background and eBOSS Lyman-alpha forest and constraints on physics beyond ΛCDM by Keir K. Rogers, Vivian Poulin

“…We find that combined Planck cosmic microwave background, baryon acoustic oscillations, and supernovae data analyzed under Λ cold dark matter (ΛCDM) are in 4.9σ tension with the extended Baryon Oscillation Spectroscopic Survey (eBOSS) Lyα forest in inference of the linear matter power spectrum at wave number ∼1hMpc^{−1} and redshift = 3. …”

Large-Angle Anomalies in the CMB by Craig J. Copi, Dragan Huterer, Dominik J. Schwarz, Glenn D. Starkman

“…We review the recently found large-scale anomalies in the maps of temperature anisotropies in the cosmic microwave background. These include alignments of the largest modes of CMB anisotropy with each other and with geometry and direction of motion of the solar ssystem, and the unusually low power at these largest scales. …”

Neutrino Mass from Cosmology by Julien Lesgourgues, Sergio Pastor

“…We show how the analysis of current cosmological observations, such as the anisotropies of the cosmic microwave background or the distribution of large-scale structure, provides an upper bound on the sum of neutrino masses of order 1 eV or less, with very good perspectives from future cosmological measurements which are expected to be sensitive to neutrino masses well into the sub-eV range.…”

Testing a Dilaton Gravity Model Using Nucleosynthesis by S. Boran, E. O. Kahya

“…Big bang nucleosynthesis (BBN) offers one of the most strict evidences for the Λ-CDM cosmology at present, as well as the cosmic microwave background (CMB) radiation. In this work, our main aim is to present the outcomes of our calculations related to primordial abundances of light elements, in the context of higher dimensional steady-state universe model in the dilaton gravity. …”

Astronomical Signatures of Dark Matter by Paul Gorenstein, Wallace Tucker

Collider and CMB complementarity of leptophilic dark matter with light Dirac neutrinos by Debasish Borah, Nayan Das, Sahabub Jahedi, Bhavya Thacker

“…The right chiral parts of light Dirac neutrinos get thermalised due to their interactions with the bath as well as leptophilic DM, leading to enhanced effective relativistic degrees of freedom N eff within reach of future cosmic microwave background (CMB) experiments. The interplay of existing bounds from cosmological observations related to DM relic and N eff, direct and indirect detection of DM, astrophysics, and collider observations leave promising discovery prospects at future electron and muon colliders along with complementary signatures at future CMB experiments.…”
