Simulation-based inference with the integrated 3PCF
David Gebauer, Anik Halder, Stella Seitz +1
We present , a simulation-based inference (SBI) framework for analysing a higher-order weak lensing statistic, the integrated 3-point correlation function (i3PCF)…
Probing baryonic feedback and cosmology with 32-point statistic of FRBs and galaxies
Kritti Sharma, Elisabeth Krause, Vikram Ravi +4
The impact of galaxy formation processes on the matter power spectrum is uncertain and may bias cosmological parameters inferred by large-scale structure surveys. Fast Radio Bursts…
Primordial Physics in the Nonlinear Universe: signatures of inflationary resonances, excitations, and scale dependence
Dhayaa Anbajagane, Hayden Lee
Primordial non-Gaussianities (PNGs) are imprints in the initial density field sourced by the dynamics of inflation. These dynamics can induce scale dependence, oscillations, and ot…
Primordial Physics in the Nonlinear Universe: mapping cosmological collider models to weak-lensing observables
Dhayaa Anbajagane, Hayden Lee
Primordial non-Gaussianities (PNGs) are features in the initial density field that provide a window into the nonlinear dynamics of particles during the inflationary epoch. Among th…
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…
The NGC3109 Satellite System: The First Systematic Resolved Search for Dwarf Galaxies Around a SMC-mass Host
Amandine Doliva-Dolinsky, Burçin Mutlu-Pakdil, Denija Crnojević +38
We report the results of the deepest search to date for dwarf galaxies around NGC3109, a barred spiral galaxy with a mass similar to that of the Small Magellanic Cloud (SMC), using…
Map-level baryonification: unified treatment of weak lensing two-point and higher-order statistics
Alan Junzhe Zhou, Marco Gatti, Dhayaa Anbajagane +3
Precision cosmology benefits from extracting maximal information from cosmic structures, motivating the use of higher-order statistics (HOS) at small spatial scales. However, predi…
