Dyson Spheres on H–R Diagram

open access: yesUniverse
The construction of Dyson spheres, megastructures designed to capture the total radiative output of stars, can be one of the most compelling techno-signature scenarios for advanced extraterrestrial civilizations.

Advanced Experiment Design Strategies for Drug Development

open access: yesAdvanced Intelligent Discovery, EarlyView.
Wang et al. analyze 592 drug development studies published between 2020 and 2024 that applied design of experiments methodologies. The review surveys both classical and emerging approaches—including Bayesian optimization and active learning—and identifies a critical gap between advanced experimental strategies and their practical adoption in ...

Early infrared astronomy [PDF]

open access: yes, 2009
International audienceI present a short history of infrared astronomy, from the first scientific approaches of the `radiant heat' in the seventeenth century to the 1970's, the time when space infrared astronomy was developing very rapidly.

SMILES: A Prototype JWST Multiband Mid-infrared Survey

open access: yesThe Astrophysical Journal
The Mid-Infrared Instrument (MIRI) for JWST is supplied with a suite of imaging band-pass filters optimized for full spectral coverage in eight intermediate-width bands from 5 to 26 μ m and a narrower one at 11.3 μ m.

GOALS-JWST: Unveiling Dusty Compact Sources in the Merging Galaxy IIZw096

open access: yesThe Astrophysical Journal Letters, 2022
We have used the Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) to obtain the first spatially resolved, mid-infrared images of IIZw096, a merging luminous infrared galaxy (LIRG) at z = 0.036.

Precise Measurements of the LMC Bar’s Geometry with Gaia DR3 and a Novel Solution to Crowding-induced Incompleteness in Star Counting

open access: yesThe Astrophysical Journal
We present new measurements of the 2D geometry of the LMC’s stellar bar with precise astrometric observations of red clump stars in Gaia DR3. We develop a novel solution to tackle crowding-induced incompleteness in Gaia data sets with the Gaia BP-RP ...
