Cosmological Remapping for Efficient Generation of 21 cm Intensity Mapping Mocks
Rahima Mokeddem, Bruno B. Bizarria, Jiajun Zhang +10
We present a novel application of cosmological rescaling, or "remapping," to generate 21 cm intensity mapping mocks for different cosmologies. The remapping method allows for compu…

Probing cosmic isotropy: Hubble constant and matter density large-angle variations with the Pantheon+SH0ES data
Rahima Mokeddem, Maria Lopes, Felipe Avila +2
In this study we investigate potential large-angle anisotropies in the angular distribution of the cosmological parameters (the Hubble constant) and (the matter density…
