Topic: A multi-probe analysis constrains a clustering tachyonic Dirac-Born-Infeld dark energy model, investigating its potential for dark energy perturbations to grow on subhorizon scales.
Topic: The cosmic microwave background temperature at $z=0.886$ is used to test energy exchange in Einstein-Cartan cosmology, with extensions to $z\simeq3$ from CO absorbers and Sunyaev-Zel'dovich clusters.
Topic: Supermassive primordial black holes are investigated as a dark matter component, focusing on their seed effect on large-scale structure formation and contrasting it with the Poisson effect.
