In this paper we explore the existing tensions in local cosmological expansion rate, ${H}_{0}$, and amplitude of clustering large-scale structure at $8{h}^{\ensuremath{-}1}\text{ }\text{ }\mathrm{Mpc}$, ${\ensuremath{\sigma}}_{8}$, as well models that claim to alleviate these tensions. We consider seven models: evolving dark energy ($w\mathrm{CDM}$), extra radiation (${N}_{\mathrm{eff}}$), massive neutrinos, curvature, primordial magnetic fields (PMF), self-interacting neutrino models, early...
The expansion history and thermal physical process that happened in the early Universe before big bang nucleosynthesis (BBN) remains relatively unconstrained by observations. Low reheating temperature universes with normalcy temperatures of ${T}_{\mathrm{RH}}\ensuremath{\sim}2\text{ }\text{ }\mathrm{MeV}$ remain consistent primordial accommodate several new physics scenarios would normally be constrained high-temperature models, including massive sterile neutrinos. We explore such scenarios'...
ABSTRACT The GALANTE optical photometric survey is observing the northern Galactic plane and some adjacent regions using seven narrow- intermediate-filters, covering a total of 1618 deg2. has been designed with multiple exposure times at least two different air masses per field to maximize its dynamic range, comparable that Gaia, ensure accuracy calibration. goal reach 1 cent precision in bands for all stars brighter than AB magnitude 17 while detecting fainter lower values signal-to-noise...
In this paper we explore the existing tensions in local cosmological expansion rate, $H_0$, and amplitude of clustering large-scale structure at $8\, h^{-1}\mathrm{Mpc}$, $\sigma_8$, as well models that claim to alleviate these tensions. We consider seven models: evolving dark energy ($w$CDM), extra radiation ($N_\mathrm{eff}$), massive neutrinos, curvature, primordial magnetic fields (PMF), self-interacting neutrino models, early (EDE). test against three data sets span full range...
We examine the performance of six-parameter $\Lambda$CDM model and its extensions in light recent cosmological observations, with particular focus on neutrino properties inferred from cosmology. Using a broad suite nine combinations datasets, three separate analyses Planck Cosmic Microwave Background (CMB) data, supernovae (SNe) survey plus DESI baryon acoustic oscillation (BAO) scale results, we derive constraints sum masses ($\Sigma m_\nu$). Our results show upper limits range $\Sigma...
The expansion history and thermal physical process that happened in the early Universe before big bang nucleosynthesis (BBN) remains relatively unconstrained by observations. Low reheating temperature universes with normalcy temperatures of $T_\mathrm{RH}\sim 2\,\mathrm{MeV}$ remain consistent primordial nucleosynthesis, accommodate several new physics scenarios would normally be constrained high-temperature models, including massive sterile neutrinos. We explore such scenarios' production...
