The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…

Deriving physical parameters of unresolved star clusters. VIII. Limits of aperture photometry for star cluster studies
Karolis DaugeviÄius, Eimantas KriÅ¡ÄiÅ«nas, Erikas CicÄnas +2
Recently, it has been noticed that the discrepancies in the integrated colour indices (CIs) between star clusters and models are mostly due to the projection of bright stars in the…
