MLLM-Routed Heterogeneous Ensembles for Robust Cross-Dataset Image Classification
Daniel Perkins, John Squires, Janou Milligan +2
Modern image classification models excel when trained on single task-specific datasets but often struggle to generalize across domains and difficulty levels. We propose ARMDIL, an…
Stellar winds of O-type stars traced by high ionization fine-structure emission lines with JWST/MIRI
Calum Hawcroft, David R. Law, Linda J. Smith +8
We investigate the presence of high ionization fine-structure emission lines across a range of 22 OB-type stars observed with JWST-MIRI as part of calibration programmes and the WI…
Mitigating Resampling Artifacts for the JWST IFU Spectrometers with Adaptive Trace Modeling
David R. Law, Melanie Clarke
The integral-field unit (IFU) spectrometers on board the James Webb Space Telescope (JWST) undersample the nearly diffraction-limited point spread function provided by the telescop…
The James Webb Space Telescope Absolute Flux Calibration. II. Mid-Infrared Instrument Imaging and Coronagraphy
Karl D. Gordon, G. C. Sloan, Macarena Garcia Marin +11
The absolute flux calibration of the Mid-Infrared Instrument Imaging and Coronagraphy is based on observations of multiple stars taken during the first 2.5 years of JWST operations…
The James Webb Space Telescope Absolute Flux Calibration. III. Mid-Infrared Instrument Medium Resolution IFU Spectrometer
David R. Law, Ioannis Argyriou, Karl D. Gordon +7
We describe the spectrophotometric calibration of the Mid-Infrared Instrument's (MIRI) Medium Resolution Spectrometer (MRS) aboard the James Webb Space Telescope (JWST). This calib…
