The Atacama Cosmology Telescope: The Persistence of Neutrino Self-Interaction in Cosmological Measurements

Kavli Affiliate: David N. Spergel | First 5 Authors: Christina D. Kreisch, Minsu Park, Erminia Calabrese, Francis-Yan Cyr-Racine, Rui An | Summary: We use data from the Atacama Cosmology Telescope (ACT) DR4 to search for the presence of neutrino self-interaction in the cosmic microwave background. Consistent with prior works, the posterior distributions we find are […]

A Kubernetes ‘Bridge’ operator between cloud and external resources

Kavli Affiliate: Elise Jennings | First 5 Authors: Boris Lublinsky, Elise Jennings, Viktória Spišaková, , | Summary: Many scientific workflows require dedicated compute resources, including HPC clusters with optimized software, quantum resources, and dedicated hardware cluster systems like Ray, for example. At the same time, many scientific workflows today are built on Kubernetes leveraging growing […]

Categorical and K-theoretic Donaldson-Thomas theory of $mathbb{C}^3$ (part I)

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We begin the study of categorifications of Donaldson-Thomas invariants associated with Hilbert schemes of points on the three-dimensional affine space, which we call DT categories. The DT category is defined to be the category of matrix factorizations on the […]

Dynamical Evolution of Brightest Cluster Galaxies and Their Host Clusters: Insights from IllustrisTNG

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jubee Sohn, Margaret J. Geller, Mark Vogelsberger, Josh Borrow, | Summary: We explore the redshift evolution of the dynamical properties of massive clusters and their brightest cluster galaxies (BCGs) at $z < 2$ based on the IllustrisTNG-300 simulation. We select 270 massive clusters with $M_{200} < 10^{14}~{rm […]

Black Hole and de Sitter Microstructures from a Semiclassical Perspective

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Chitraang Murdia, Yasunori Nomura, Kyle Ritchie, , | Summary: We describe two different, but equivalent semiclassical views of black hole physics in which the equivalence principle and unitarity are both accommodated. In one, unitarity is built-in, while the black hole interior emerges only effectively as a collective […]

Population properties and multimessenger prospects of neutron star-black hole mergers following GWTC-3

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Philippe Landry, Salvatore Vitale, , | Summary: Neutron star-black hole (NSBH) mergers detected in gravitational-waves have the potential to shed light on supernova physics, the dense matter equation of state, and the astrophysical processes that power their potential electromagnetic counterparts. We use the population of […]
