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…
Faint white dwarf flux standards: data and models
Ralph C. Bohlin, Susana Deustua, Gautham Narayan +7
Fainter standard stars are essential for the calibration of larger telescopes. This work adds to the CALSPEC (calibration spectra) database 19 faint white dwarfs (WDs) with all-sky…
A network of cooler white dwarfs as infrared standards for flux calibration
Abbigail K. Elms, Nicola Pietro Gentile Fusillo, Pier-Emmanuel Tremblay +6
The accurate flux calibration of observational data is vital for astrophysics and cosmology because absolute flux uncertainties of stellar standards propagate into scientific resul…
The updated BOSZ synthetic stellar spectral library
Szabolcs Mészáros, Ralph Bohlin, Carlos Allende Prieto +9
Context. The modeling of stellar spectra of flux standards observed by the Hubble and James Webb space telescopes requires a large synthetic spectral library that covers a wide atm…
