A two-component profile of baryonic feedback: hydrostatic and diffuse gas

Kaitlyn Shavelle, Jared Siegel, Leah Bigwood +2

Baryonic feedback processes redistribute gas within and beyond dark matter halos, however, the resulting gas distribution remains highly uncertain, limiting predictions of the matt…

Confronting cosmic shear astrophysical uncertainties: DES Year 3 revisited

Leah Bigwood, Jamie McCullough, Jared Siegel +19

Cosmology from weak gravitational lensing has been limited by astrophysical uncertainties in baryonic feedback and intrinsic alignments. By calibrating these effects using external…

The suppression of the matter power spectrum: strong feedback from X-ray gas mass fractions, kSZ effect profiles, and galaxy-galaxy lensing

Jared Siegel, Leah Bigwood, Alexandra Amon +6

Baryon feedback redistributes gas relative to the underlying dark matter distribution and suppresses the matter power spectrum on small scales, but the amplitude and scale dependen…

The kinetic Sunyaev Zeldovich effect as a benchmark for AGN feedback models in hydrodynamical simulations: insights from DESI + ACT

Leah Bigwood, Masaya Yamamoto, Jared Siegel +7

Baryonic feedback remains one of the largest uncertainties in cosmological hydrodynamical simulations, with different prescriptions producing divergent predictions for the fraction…

Spatially Resolved Galaxy-Dust Modeling with Coupled Data-Driven Priors

Jared Siegel, Peter Melchior

A notorious problem in astronomy is the recovery of the true shape and spectral energy distribution (SED) of a galaxy despite attenuation by interstellar dust embedded in the same…
