Kavli Affiliate: Robert M. Wald | First 5 Authors: Po-Ning Chen, Daniel Paraizo, Robert M. Wald, Mu-Tao Wang, Ye-Kai Wang | Summary: We introduce a notion of "cross-section continuity" as a criterion for the viability of definitions of angular momentum, $J$, at null infinity: If a sequence of cross-sections, ${mathcal C}_n$, of null infinity converges […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Alexander P. Ji, Rohan P. Naidu, Kaley Brauer, Yuan-Sen Ting, Joshua D. Simon | Summary: We present the first high-resolution chemical abundances of seven stars in the recently discovered high-energy dwarf galaxy stream Typhon. Typhon stars have apocenters reaching to ${gtrsim}100$ kpc, making this the first […]
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 […]
Kavli Affiliate: Geza Gyuk | First 5 Authors: Tim Lister, Michael S. P. Kelley, Carrie E. Holt, Henry H. Hsieh, Michele T. Bannister | Summary: The LCO Outbursting Objects Key (LOOK) Project uses the telescopes of the Las Cumbres Observatory (LCO) Network to: (1) to systematically monitor a sample of Dynamically New Comets over the […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Christian Ferko, Savdeep Sethi, , , | Summary: We explore whether one can $T overline{T}$ deform a collection of theories that are already $T overline{T}$-deformed. This allows us to define classes of irrelevant deformations that know about subsystems. In some basic cases, we explore the spectrum that […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Dan Hooper, Aurora Ireland, Gordan Krnjaic, , | Summary: The origin of our universe’s cosmological magnetic fields remains a mystery. In this study, we consider whether these magnetic fields could have been generated in the early universe by a population of charged, spinning primordial black holes. To […]
Kavli Affiliate: Michael Gladders | First 5 Authors: Manuel Solimano, Jorge González-López, Manuel Aravena, Evelyn Johnston, Cristóbal Moya-Sierralta | Summary: Spatially extended halos of Lyman Alpha (Ly$alpha$) emission are now ubiquitously found around high-redshift star-forming galaxies. But our understanding of the nature and powering mechanisms of these halos is still hampered by the complex radiative […]
Kavli Affiliate: Michael Gladders | First 5 Authors: Manuel Solimano, Jorge González-López, Manuel Aravena, Evelyn Johnston, Cristóbal Moya-Sierralta | Summary: Spatially extended halos of H I Ly$alpha$ emission are now ubiquitously found around high-redshift star-forming galaxies. But our understanding of the nature and powering mechanisms of these halos is still hampered by the complex radiative […]

Kavli Affiliate: Richard Kessler | First 5 Authors: Martine Lokken, Alexander Gagliano, Gautham Narayan, Renée Hložek, Richard Kessler | Summary: As we observe a rapidly growing number of astrophysical transients, we learn more about the diverse host galaxy environments in which they occur. Host galaxy information can be used to purify samples of cosmological Type […]
