EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics

Kavli Affiliate: Herman Marshall | Summary:The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of IXPE, EXPO is designed to overcome its two main limitations, the narrow 2-8 keV energy band and the very slow repointing […]

Pandora cluster Lensing, AGN, and Transient Exploration (PLATE) from JWST Multi-Epoch Imaging. I. Discovery of a type II supernova candidate in a spiral galaxy at $z=0.7$

Kavli Affiliate: Subo Dong | Summary:We report the discovery and multi-wavelength analysis of a $zsim0.7$ transient PLATE-23a in the Abell 2744 field, as the first results of the Pandora Lensing, AGN, and Transient Exploration (PLATE) project. Using multi-epoch JWST NIRCam imaging spanning from 2022 to 2025, we detect PLATE-23a in 12 filters. Difference-imaging analysis reveals […]

Leveraging Impact Parameter to Mitigate the Transit Light Source Effect: Early Insights from TRAPPIST-1

Kavli Affiliate: Sara Seager | Summary:Stellar activity complicates exoplanet transmission spectra, particularly for smaller planets around M dwarfs with JWST. The transit light source (TLS) effect, the imprinting of spectral differences between the average stellar disk and the occulted transit chord onto the transmission spectrum, makes it challenging to directly use the out-of-transit spectrum to […]

Strange Metal Hall Effect in Underdoped BaFe$_2$(As$_1-x$P$_x$)$_2$

Kavli Affiliate: James Analytis| Summary:The unusual transport properties of strange metals point to the breakdown of the quasiparticle picture, the understanding of which remains one of the most vexing problems in physics. Here, we report investigations of the electrical Hall effect of the strange metal superconductor BaFe$_2$(As$_1-x$P$_x$)$_2$. We show that a doping-independent contribution to the […]

Three-dimensional imaging of oxygen dopant distribution in Sr$_2$CuO$_3+δ$ by electron ptychography

Kavli Affiliate: David Muller | Summary:Oxygen dopants play a critical role in tuning the properties of cuprate superconductors, yet it is challenging to visualize them at the atomic scale. Here, we use multislice electron ptychography to directly image oxygen dopants in a Sr2CuO3+delta film. We observe oxygen dopants at interstitial sites between the Cu-O chains, […]

The VariableTNG project: mass-dependent regulation of galaxy morphology by baryonic feedback

Kavli Affiliate: Luis Ho | Summary:Galaxy morphology is shaped by both assembly history and baryonic processes, but their relative roles remain uncertain. We use the VariableTNG (VTNG) simulation suite to investigate how variations in baryonic feedback regulate galaxy morphology while keeping the initial conditions fixed. VTNG consists of cosmological magnetohydrodynamic simulations performed with the moving-mesh […]

Fast Control for LIGO Interferometer Lock Acquisition

Kavli Affiliate: Rana Adhikari | Summary:Gravitational wave observatories are large scale laser interferometers which are held on resonance to facilitate the detection of gravitational waves. Achieving this resonant condition is a time consuming process, and in the LIGO gravitational-wave observatories this procedure has a relatively low success rate. This limitation leads to a loss of […]

The structural logic of insect olfactory receptor assembly and gating

Kavli Affiliate: Vanessa Ruta | Authors: Navid Paknejad, Dragana Nesic, Beth Graczyk, Jackson Rogow, Mackenzie A. Yedlin, Chidera Udedibia, Joel Butterwick and Vanessa Ruta | Summary: Insects detect the chemical world using a large family of odorant-gated ion channels, each formed from a variable odorant-binding subunit (OR) and a single conserved co-receptor Orco. This modular […]
