Foreground removal and 21 cm signal estimates: comparing different blind methods for the BINGO Telescope
Alessandro Marins, Filipe B. Abdalla, Elcio Abdalla +17
The BINGO radiotelescope will observe hydrogen distribution using Intensity Mapping (IM) to analyze the Dark Energy paradigm through Baryon Acoustic Oscillations. The target signal…

Constraints on interacting dark energy revisited: implications for the Hubble tension
Gabriel A. Hoerning, Ricardo G. Landim, Luiza O. Ponte +3
We revisit a class of coupled dark energy models where dark energy interacts with dark matter via phenomenological energy exchange terms. We include the perturbation of the Hubble…
