Deriving Physical Properties from Broadband Photometry with Prospector: Description of the Model and a Demonstration of its Accuracy Using 129 Galaxies in the Local Universe [PDF]
, 2016 Broadband photometry of galaxies measures an unresolved mix of complex stellar populations, gas, and dust. Interpreting these data is a challenge for models: many studies have shown that properties derived from modeling galaxy photometry are uncertain by

Materials and Corrosion, EarlyView., 2021 Several methods to measure the critical chloride content Ccrit of steel in concrete are compared on the basis of 12% chromium steel and carbon steel. The resulting Ccrit depends on the method used. The reasons for this and the corresponding influencing parameters are discussed in this article.

Galaxy surface photometry [PDF]
, 1999 We describe galaxy surface photometry based on fitting ellipses to the isophotes of the galaxies. Example galaxies with different isophotal shapes are used to illustrate the process, including how the deviations from elliptical isophotes are quantified ...

Single molecule mass photometry of nucleic acids
bioRxiv, 2020 Mass photometry is a recently developed methodology capable of detection, imaging and mass measurement of individual proteins under solution conditions. Here, we show that this approach is equally applicable to nucleic acids, enabling their facile, rapid

Effective temperatures and radii of planet-hosting stars from IR photometry [PDF]
, 2003 In this paper we present and analyse determinations of effective temperatures of planet-hosting stars using infrared (IR) photometry. One of our goals is the comparison with spectroscopic temperatures to evaluate the presence of systematic effects that ...

Overview of Gaia Multi-Color Photometry
Open Astronomy, 2003 Gaia will obtain multi-color photometry for astrometric and astrophysical purposes. A photometry in five broad bands and with high angular resolution will be obtained after every astrometric observation of a star, especially for the sake of correcting ...
