Kavli Affiliate: Alexander Ji | Summary:Owing to their proximity to the Milky Way, the Large and Small Magellanic Clouds (L/SMC) uniquely probe the evolution of low-mass galaxies undergoing mutual interactions. In this work, we investigate the connection between the star formation histories (SFHs) of the L/SMC measured from HST imaging in the Scylla survey and […]
Kavli Affiliate: Wei Gao| Summary:Two-dimensional MXenes are promising solid lubricants, but the roles of compositional complexity and surface chemistry in governing interfacial friction remain unclear. Here, we systematically investigate the adhesion and friction behaviors of medium-entropy (ME) MXenes, TiVNbMoC3 and TiVCrMoC3, and compare them with conventional titanium carbide MXenes, Ti2C and Ti3C2, using a SiO2 […]
Kavli Affiliate: Kiyoshi Masui | Summary:The sensitivity of radio telescopes is becoming increasingly limited by the presence of radio frequency interference (RFI), which will worsen as the radio spectrum becomes more crowded. One context where this poses a challenge is the field of fast radio burst (FRB) science, where there is increasing scientific interest in […]
Kavli Affiliate: James Bock | Summary:We present map-making methodologies and preliminary spectral data cubes for SPHEREx, a NASA Explorer mission that launched in March 2025 and has been performing an all-sky near-infrared spectral survey. The SPHEREx instrument observes from 0.75 to 5.0 microns with a spectral resolution ranging from 35 to 130 and a pixel […]
Kavli Affiliate: Avi Shporer | Summary:Most known planets are found around metal-rich host stars, which has made it difficult to determine whether a lower metallicity limit for planet formation exists and how the properties of planets born in low-metallicity environments may differ from those with metal-rich origins. We present the discovery and characterization of TOI-7169 […]

Kavli Affiliate: Lina Necib | Summary:The majority of terrestrial direct detection experiments for Dark Matter (DM) rely on the Standard Halo Model (SHM), which assumes the local DM velocity distribution follows a Maxwell-Boltzmann distribution. However, galaxy mergers can deposit DM that remains kinematically clustered today, inducing deviations from the smooth SHM prediction. Previous studies have […]
Kavli Affiliate: Kiyoshi Masui | Summary:Observations with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) have been used to measure the 21 cm intensity mapping auto power spectrum, at $zsim 1$, over a frequency range from 608.2 MHz to 707.8 MHz at wavenumbers $0.4~h~rm Mpc^-1 lesssim k lesssim 1.5~h~rm Mpc^-1$. In this paper, we present the […]
Kavli Affiliate: George Efstathiou | Summary:Fuzzy Dark Matter (FDM), particularly in the $10^-22$ eV mass regime is frequently used to characterize wave-like interference effects. It exhibits macroscopic wave properties, which drive distinct baryonic dynamics within collapsed haloes. Using the hydrodynamical code AREPO with the AxiREPO module and primordial chemistry, we simulate the assembly of haloes […]
Kavli Affiliate: George Efstathiou | Summary:Fuzzy Dark Matter (FDM), composed of ultra-light axions ($m_a sim 1 times 10^-22$ eV), exhibits wave-like properties that can significantly impact early-universe star formation. Using the arepo code with the axirepo module, we simulate the assembly of haloes across a range of axion masses ($1 times 10^-22$ eV $le m_a […]
