Rubin LSST DP2 unveils almost-dark galaxies in the Virgo Cluster

Kavli Affiliate: Kevin Reil | Summary:Galaxies with the faintest surface brightness are currently known only in the Local Group. Similar objects should exist beyond our vicinity and are crucial for understanding galaxy evolution, structure, and dark matter content, yet surveys have not reached the depth required to detect them systematically. We present a population of […]

A Binary Flux Calibrator Reveals the Scientific Potential of Short-integration JWST MIRI Imaging to Directly Detect sub-Jupiter Exoplanets

Kavli Affiliate: Andrew Vanderburg | Summary:We report the direct imaging detection of a stellar companion to HD 101452 (HIP 56925; Gaia DR3 5384905720847544192), an A star historically used as an infrared flux calibrator. The companion was identified from an asymmetry in the stellar PSF using short-integration (<1 min), noncoronagraphic JWST MIRI imaging from 15 – […]

Massive Galaxy Halos Contain Less Inner Dark Matter Than Predicted

Kavli Affiliate: Roberto Maiolino | Summary:The mass profiles of galaxy halos encode how baryons reshape dark matter distribution, yet direct observational constraints across the full radial range remain scarce. Here we combine stellar kinematics from MaNGA, H I dynamical measurements from ALFALFA, and independently calibrated halo masses of SDSS groups to statistically reconstruct the mass […]

An Updated Model for Epsilon Eridani b and Prospects for Imaging with the Roman Coronagraph

Kavli Affiliate: Dimitri Mawet| Summary:Epsilon Eridani b, the nearest known Jupiter analog, has its orbit and mass constrained from radial velocity (RV) and absolute astrometry, and its atmosphere from JWST/NIRCam imaging upper limits in Sanghi et al. 2026. Here we follow up that work with a self-consistent model of Epsilon Eridani b that treats all […]

The Nancy Grace Roman Space Telescope Coronagraph Community Participation Program

Kavli Affiliate: Bruce Macintosh | Summary:In preparation for the operational phase of the Nancy Grace Roman Space Telescope, NASA has created the Coronagraph Community Participation Program (CPP) to prepare for and execute Coronagraph Instrument technology demonstration observations. The CPP is composed of 7 small, US-based teams, selected competitively via the Nancy Grace Roman Space Telescope […]

Probing Lorentz-violating scalar forces and dark matter with precision matter and antimatter experiments

Kavli Affiliate: Yevgeny Stadnik | Summary:We explore a class of Lorentz-violating scalar-field models where the effects of the scalar field on antimatter can be strongly enhanced compared to matter. Non-trivial differences in phenomenology arise for spectroscopy measurements depending on whether the scalar field changes slowly or rapidly on the atomic scale. We highlight opportunities for […]
