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…
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.,…
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…
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…
Deciphering baryonic feedback with galaxy clusters
Chun-Hao To, Shivam Pandey, Elisabeth Krause +3
Upcoming cosmic shear analyses will precisely measure the cosmic matter distribution at low redshifts. At these redshifts, the matter distribution is affected by galaxy formation p…
GODMAX: Modeling gas thermodynamics and matter distribution using JAX
Shivam Pandey, Jaime Salcido, Chun-Hao To +4
We introduce GODMAX (Gas thermODynamics and Matter distribution using jAX), a novel code designed to calculate correlations between the cosmological matter distribution and various…
Inferring galaxy cluster masses from cosmic microwave background lensing with neural simulation based inference
Eric J. Baxter, Shivam Pandey
Gravitational lensing by massive galaxy clusters distorts the observed cosmic microwave background (CMB) on arcminute scales, and these distortions carry information about cluster…
