Backlighting the Cosmic Web with Fast Radio Bursts: An Anthology of Dispersion Measure Cross-Correlations with Large-Scale Structure and Baryon Tracers

Kritti Sharma, Elisabeth Krause, Vikram Ravi +11

Fast Radio Bursts (FRBs) probe baryons permeating the cosmic web through their dispersion measures (DMs), which encode the integrated electron density along cosmological sightlines…

Testing halo models for constraining astrophysical feedback with multi-probe modeling: I. 3D Power spectra and mass fractions

Pranjal R. S., Shivam Pandey, Dhayaa Anbajagane +2

Upcoming Stage-IV surveys will deliver measurements of distribution of matter with unprecedented precision, demanding highly accurate theoretical models for cosmological parameter…

Deciphering Baryonic Feedback from ACT tSZ Galaxy Clusters

Nihar Dalal, Chun-Hao To, Chris Hirata +4

The next generation of cosmology surveys will probe the matter distribution of the universe to unparalleled precision. To match this level of precision in cosmological parameter es…

Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters

Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93

The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…

Minimizing Contaminant Leakage in Internal Linear Combination Maps Using a Data-Driven Approach

Kristen M. Surrao, Shivam Pandey, J. Colin Hill +1

The thermal Sunyaev-Zel'dovich (tSZ) effect, the inverse-Compton scattering of cosmic microwave background (CMB) photons off high-energy electrons, is a powerful probe of hot, ioni…

Map-level baryonification: Efficient modelling of higher-order correlations in the weak lensing and thermal Sunyaev-Zeldovich fields

Dhayaa Anbajagane, Shivam Pandey, Chihway Chang

Semi-analytic methods can generate baryon-corrected fields from N-body simulations (``baryonification'') and are rapidly becoming a ubiquitous tool in modeling structure formation…
