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…
Joint X-ray, kinetic Sunyaev-Zeldovich, and weak lensing measurements: toward a consensus picture of efficient gas expulsion from groups and clusters
Jared Siegel, Alexandra Amon, Ian G. McCarthy +7
There is no consensus on how baryon feedback shapes the underlying matter distribution from either simulations or observations. We confront the uncertain landscape by jointly analy…
The case for large-scale AGN feedback in galaxy formation simulations: insights from XFABLE
Leah Bigwood, Martin A. Bourne, Vid Irsic +2
While cosmological simulations of galaxy formation have reached maturity, able to reproduce many fundamental galaxy and halo properties, no consensus has yet been reached on the im…
