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

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 […]

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

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

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 […]

Quantum nondemolition measurements with optical parametric amplifiers for ultrafast universal quantum information processing

Kavli Affiliate: Alireza Marandi | First 5 Authors: Ryotatsu Yanagimoto, Rajveer Nehra, Ryan Hamerly, Edwin Ng, Alireza Marandi | Summary: Realization of a room-temperature ultra-fast photon-number-resolving (PNR) quantum nondemolition (QND) measurement would have significant implications for photonic quantum information processing (QIP), enabling, e.g., deterministic quantum computation in discrete-variable architectures, but the requirement for strong coupling […]
