Reddened, Redshifted, or Intrinsically Red? Understanding Near-Ultraviolet Colors of Type Ia Supernovae [PDF]
Understanding the intrinsic colors of Type Ia supernovae (SNe Ia) is important to their use as cosmological standard candles. Understanding the effects of reddening and redshift on the observed colors are complicated and dependent on the intrinsic ...

Exploring Optical and Electrical Gas Detection Based on Zinc-Tetraphenylporphyrin Sensitizer [PDF]
We developed optical waveguide (OWG), ultraviolet-visible spectrophotometry (UV-vis), and electrically operated gas sensors by utilizing zinc-tetraphenylporphyrin (ZnTPP) as sensitizer. Strikingly, ZnTPP thin-film/K+-exchanged glass optical waveguide (OWG) sensing element exhibits a superior signal-to-noise ratio (SNR) of 109.6 upon 1 ppm NO2 gas ...

Techniques and Review of Absolute Flux Calibration from the Ultraviolet to the Mid-Infrared [PDF]
The measurement of precise absolute fluxes for stellar sources has been pursued with increased vigor since the discovery of the dark energy and the realization that its detailed understanding requires accurate spectral energy distributions (SEDs) of redshifted Ia supernovae in the rest frame.
