Kavli Affiliate: Salman Habib | First 5 Authors: Katrin Heitmann, Thomas Uram, Nicholas Frontiere, Salman Habib, Adrian Pope | Summary: In this paper we describe the set of “New Worlds Simulations”, three very large cosmology simulations, Qo’noS, Vulcan, and Ferenginar, that were carried out on the Summit supercomputer with the Hardware/Hybrid Cosmology Code, HACC. The […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Byung Ju Park, Jae Jin Choi, Eunju Jeon, Jinyu Kim, Kyungwon Kim | Summary: We report new constraints on axion-like particles (ALPs) using data from the NEON experiment, which features a 16.7 kg of NaI(Tl) target located 23.7 meters from a 2.8 GW thermal power nuclear reactor. […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: We discuss the possibility that the two nearby resonances observed by BESIII partially below the ,$pbar p$, threshold might be due to mixing between two metastable states with the same $J^{PC}=0^{-+}$ quantum numbers, but rather different internal […]

Kavli Affiliate: Thomas Crawford | First 5 Authors: David Zegeye, Thomas Crawford, Jens Chluba, Mathieu Remazeilles, Keith Grainge | Summary: Contemporary cosmic microwave background (CMB) experiments typically have observing bands covering the range 20 – 800 GHz. Certain science goals, including the detection of $mu$-type distortions to the CMB spectrum and the characterization of low-frequency […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: Dark photons are a theorized massive spin-1 particle which can be produced via various mechanisms, including cosmological gravitational particle production (GPP) in the early universe. In this work, we extend previous results for GPP of […]

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: M. M. Phillips, C. Ashall, Peter J. Brown, L. Galbany, M. A. Tucker | Summary: Understanding the nature of the luminous 1991T-like supernovae is of great importance to supernova cosmology as they are likely to have been more common in the early universe. In this paper […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Alexandra G. Hanselman, Aditya Vijaykumar, Maya Fishbach, Daniel E. Holz, | Summary: The discovery of GW170817 provided the first direct gravitational-wave measurement of the Hubble constant, $H_0$, demonstrating the potential power of standard-siren cosmology. The dark siren approach can be utilized for gravitational-wave sources in the […]
