Large Variations Seen in First Ultraviolet Spectroscopic M33 Dust Extinction Curves
Karl D. Gordon, Petia Yanchulova Merica-Jones, Geoffrey C. Clayton +4
Dust extinction curves provide one of the main avenues to understanding the detailed nature of dust grains and accounting for the effects of dust on observations of many astrophysi…
DAmodel: Hierarchical Bayesian Modelling of DA White Dwarfs for Spectrophotometric Calibration
Benjamin M. Boyd, Gautham Narayan, Kaisey S. Mandel +17
We use hierarchical Bayesian modelling to calibrate a network of 32 all-sky faint DA white dwarf (DA WD) spectrophotometric standards () alongside three CALSPEC st…
Nature or Nurture: LMC-like Dust in the Solar Metallicity Galaxy M31
Geoffrey C. Clayton, Petia Yanchulova Merica-Jones, Karl D. Gordon +6
Using the {\it Hubble Space Telescope}/Space Telescope Imaging Spectrograph, ultraviolet (UV) extinction curves have been measured in M31 along thirteen new sightlines, increasing…
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…
