Absolute Flux Calibrations for the Nancy Grace Roman Space Telescope Coronagraph Instrument

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Lindsey Payne, Robert T. Zellem, Marie Ygouf, Bruce Macintosh, | Summary: The Nancy Grace Roman Space Telescope’s (Roman) Coronagraph Instrument is a technology demonstration equipped to achieve flux contrast levels of up to 10$^{-9}$. This precision depends upon the quality of observations and their resultant on-sky corrections […]

Metal Mixing in the R-Process Enhanced Ultra-Faint Dwarf Galaxy Reticulum II

Kavli Affiliate: Anna Frebel | First 5 Authors: Alexander P. Ji, Joshua D. Simon, Ian U. Roederer, Ekaterina Magg, Anna Frebel | Summary: The ultra-faint dwarf galaxy Reticulum~II was enriched by a single rare and prolific r-process event. The r-process content of Reticulum~II thus provides a unique opportunity to study metal mixing in a relic […]

LyC escape from SPHINX galaxies in the Epoch of Reionization

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Joakim Rosdahl, Jérémy Blaizot, Harley Katz, Taysun Kimm, Thibault Garel | Summary: We measure escape fractions, $f_{rm esc}$, of ionizing radiation from galaxies in the SPHINX suite of cosmological radiation-hydrodynamical simulations of reionization, resolving halos with $M_{rm vir} gtrapprox 7.5 times 10^7 M_{odot}$ with a minimum cell […]

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 […]
