Quantifying the impact of selection effects on FRB DM- relation cosmological inference
Kritti Sharma, Vikram Ravi, Liam Connor +3
Fast Radio Bursts (FRBs) have emerged as powerful probes of baryonic matter in the Universe, offering constraints on cosmological and feedback parameters through their extragalacti…

A hydrodynamical simulations-based model that connects the FRB DM--redshift relation to suppression of the matter power spectrum via feedback
Kritti Sharma, Elisabeth Krause, Vikram Ravi +3
Understanding the impact of baryonic feedback on the small-scale (Mpc) matter power spectrum is a key astrophysical challenge, and essential for interpreti…

Impact of cosmology dependence of baryonic feedback in weak lensing
Pranjal R. S., Elisabeth Krause, Klaus Dolag +4
Robust modeling of non-linear scales is critical for accurate cosmological inference in Stage IV surveys. For weak lensing analyses in particular, a key challenge arises from the i…
