Milky Way-est: Cosmological Zoom-in Simulations with Large Magellanic Cloud and Gaia-Sausage-Enceladus Analogs

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Deveshi Buch, Ethan O. Nadler, Risa H. Wechsler, Yao-Yuan Mao, | Summary: We present Milky Way-est, a suite of 20 cosmological cold-dark-matter-only zoom-in simulations of Milky Way (MW)-like host halos. Milky Way-est hosts are selected such that they: ($i$) are consistent with the MW’s measured halo […]

A Beehive Haloscope for High-mass Axion Dark Matter

Kavli Affiliate: Chao-Lin Kuo | Summary:We propose a new haloscope geometry that can arbitrarily increase the resonator volume for a given target axion mass. This geometry consists of closely packed, overlapping coaxial cavities operating as a single resonator. While the resonant frequency is still determined by the dimensions of the individual "cells," the strong interactions […]

Constraints on Dark Matter from Dynamical Heating of Stars in Ultrafaint Dwarfs. Part 2: Substructure and the Primordial Power Spectrum

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, , , | Summary: There is a large and growing interest in observations of small-scale structure in dark matter. We propose a new way to probe dark matter structures in the $sim 10 – 10^8 , M_odot$ range. This allows us […]

Dynamic motion trajectory control with nanoradian accuracy for multi-element X-ray optical systems via laser interferometry

Kavli Affiliate: Brian Lantz | Summary:The past decades have witnessed the development of new X-ray beam sources with brightness growing at a rate surpassing Moore’s law. Current and upcoming diffraction limited and fully coherent X-ray beam sources, including multi-bend achromat based synchrotron sources and high repetition rate X-ray free electron lasers, puts increasingly stringent requirements […]

Sora as a World Model? A Complete Survey on Text-to-Video Generation

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:The evolution of video generation from text, from animating MNIST to simulating the world with Sora, has progressed at a breakneck speed. Here, we systematically discuss how far text-to-video generation technology supports essential requirements in world modeling. We curate 250+ studies on […]

Optical Photometric Indicators of Galaxy Cluster Relaxation

Kavli Affiliate: Steven W. Allen | First 5 Authors: Madeline C. Casas, Ky Putnam, Adam B. Mantz, Steven W. Allen, Taweewat Somboonpanyakul | Summary: The most dynamically relaxed clusters of galaxies play a special role in cosmological studies as well as astrophysical studies of the intracluster medium (ICM) and active galactic nucleus feedback. While high […]
