Kavli Affiliate: Anthony Lasenby | Summary:We investigate the effects of non-zero spatial curvature on cosmic inflation in the light of cosmic microwave background (CMB) anisotropy measurements from the Planck 2018 legacy release and from the 2015 observing season of BICEP2 and the Keck Array. Even a small percentage of non-zero curvature today would significantly limit […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Alice Concas, Roberto Maiolino, Mirko Curti, Connor Hayden-Pawson, Michele Cirasuolo | Summary: We investigate the presence of ionised gas outflows in a sample of 141 main-sequence star-forming galaxies at $1.2<z<2.6$ from the KLEVER (KMOS Lensed Emission Lines and VElocity Review) survey. Our sample covers an exceptionally wide […]

Addison, Peter Adshead, Zeeshan Ahmed | Summary: This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin and evolution of the Universe, from the […]
Kavli Affiliate: Richard Hills | Summary:This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin and evolution of the Universe, from the highest energies at the dawn of time through the growth of structure to the present day.

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Davide Gerosa, Cecilia Maria Fabbri, Ulrich Sperhake, , | Summary: The mass of a Kerr black hole can be separated into irreducible and rotational components -the former is a lower limit to the energy that cannot be possibly extracted from the event horizon and is related to […]
Kavli Affiliate: Ulrich Sperhake | Summary:The mass of a Kerr black hole can be separated into irreducible and rotational components -the former is a lower limit to the energy that cannot be possibly extracted from the event horizon and is related to its area. Here we compute the irreducible masses of the stellar-mass black holes […]
Kavli Affiliate: A. C. Davis | Summary:We report the first measurement of the parity-violating elastic electron scattering asymmetry on 27Al. The 27Al elastic asymmetry is A_PV = 2.16 +- 0.11 (stat) +- 0.16 (syst) ppm, and was measured at <Q^2> =0.02357 +- 0.0001 GeV^2, <theta_lab> = 7.61 +- 0.02 degrees, and <E_lab> = 1.157 GeV […]
Kavli Affiliate: A. C. Davis | Summary:Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the direct detection of gravitational waves with LIGO and Virgo, and many others. This white paper is the result of a collaborative effort that […]
Kavli Affiliate: George Efstathiou | First 5 Authors: The HERA Collaboration, Zara Abdurashidova, James E. Aguirre, Paul Alexander, Zaki Ali | Summary: Recently, the Hydrogen Epoch of Reionization Array (HERA) collaboration has produced the experiment’s first upper limits on the power spectrum of 21-cm fluctuations at z~8 and 10. Here, we use several independent theoretical […]
