The SZ flux-mass ($Y$-$M$) relation at low halo masses: improvements with symbolic regression and strong constraints on baryonic feedback

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, J. Colin Hill, Shivam Pandey, Francisco Villaescusa-Navarro | Summary: Feedback from active galactic nuclei (AGN) and supernovae can affect measurements of integrated SZ flux of halos ($Y_mathrm{SZ}$) from CMB surveys, and cause its relation with the halo mass ($Y_mathrm{SZ}-M$) to deviate from […]

Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, J. Colin Hill, Shivam Pandey, Francisco Villaescusa-Navarro | Summary: Ionized gas in the halo circumgalactic medium leaves an imprint on the cosmic microwave background via the thermal Sunyaev-Zeldovich (tSZ) effect. Feedback from active galactic nuclei (AGN) and supernovae can affect the measurements […]

Quantum interference in gravitational particle production

Posted by klaurent Chicago

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward Basso, Daniel J. H. Chung, Edward W. Kolb, Andrew J. Long, | Summary: Previous numerical investigations of gravitational particle production during the coherent oscillation period of inflation displayed unexplained fluctuations in the spectral density of the produced particles. We argue that these features are due […]
