DOI: 10.1007/jhep03(2022)198
Abstract: Abstract We discuss cosmological constraints on a dark scalar particle mixing with the Standard Model Higgs boson. We pay particular attention to the dark scalar production process when the reheating temperature of the Universe is… read more here.

DOI: 10.1016/j.dark.2018.10.007
Abstract: Abstract We reconsider the dynamics of the Universe in the presence of interactions in the cosmological dark sector. A class of interacting models is introduced via a real function f r of the ratio r… read more here.

DOI: 10.1051/0004-6361/202039043
Abstract: Context. The study of the magnification bias produced on high-redshift sub-millimetre galaxies by foreground galaxies through the analysis of the cross-correlation function was recently demonstrated as an interesting independent alternative to the weak-lensing shear as… read more here.

DOI: 10.1088/1475-7516/2019/06/033
Abstract: We investigate how the cosmological constraints from SNe Ia are improved by including the effects of weak-lensing convergence. To do so, we introduce the lognormal function as the convergence PDF modeling the lensing scatter of… read more here.

DOI: 10.1093/mnras/stad957
Abstract: We present the first cosmological study of a sample of eROSITA clusters, which were identified in the eROSITA Final Equatorial Depth Survey (eFEDS). In a joint selection on X-ray and optical observables, the sample contains… read more here.

DOI: 10.1093/mnras/stw2725
Abstract: We present results from the 2D anisotropic baryon acoustic oscillation (BAO) signal present in the final data set from the WiggleZ Dark Energy Survey. We analyse the WiggleZ data in two ways: first using the… read more here.

DOI: 10.1093/mnras/sty2160
Abstract: The standard model of cosmology, {\Lambda}CDM, is the simplest model that matches the current observations, but it relies on two hypothetical components, to wit, dark matter and dark energy. Future galaxy surveys and cosmic microwave… read more here.
