Influence of Mie scattering on nanoparticles with different particle sizes and shapes: photometry and analytical ultracentrifugation with absorption optics [PDF]
Journal of the Serbian Chemical Society, 2005 Nanoparticles are used in large quantities for very different applications. A precise determination of the diameter and the particle size distribution which is responsible for the application properties is therefore essential.

Reference-less detection, astrometry, and photometry of faint companions with adaptive optics [PDF]
, 2009 We propose a complete framework for the detection, astrometry, and photometry of faint companions from a sequence of adaptive optics corrected short exposures. The algorithms exploit the difference in statistics between the on-axis and off-axis intensity.

DDO68 C: The Actual Appearance of a Ghost Satellite Dwarf through Adaptive Optics at the Large Binocular Telescope [PDF]
The Astrophysical Journal Letters, 2023 Through adaptive optics (AO) imaging with the SOUL+LUCI instrument at the Large Binocular Telescope we were able to resolve, for the first time, individual stars in the gas-rich galaxy DDO68 C. This system was already suggested to be interacting with the

Quantifying the Contamination from nearby Stellar Companions in Gaia DR3 Photometry [PDF]
The Astronomical JournalIdentifying and removing binary stars from stellar samples is a crucial but complicated task. Regardless of how carefully a sample is selected, some binaries will remain and complicate interpretation of results, especially via flux contamination of ...

PROBABILITY OF THE PHYSICAL ASSOCIATION OF 104 BLENDED COMPANIONS TOKEPLEROBJECTS OF INTEREST USING VISIBLE AND NEAR-INFRARED ADAPTIVE OPTICS PHOTOMETRY [PDF]
, 2016 We determine probabilities of physical association for stars in blended Kepler Objects of Interest (KOIs), and find that of companions within ∼4″ are consistent with being physically unassociated with their primary.
