Using a GPS-Aided Inertial System for Coarse-Pointing of Free-Space Optical Communication Terminals [PDF]
, 2006 In the Capanina project, it has been shown that it is possible to use solely GPS positions for coarse-pointing of a stratospheric free-space optical communication terminal.

A Possible Mechanism for the “Late Phase” in Stellar White-light Flares
The Astrophysical Journal, 2023 M dwarf flares observed by the Transiting Exoplanet Survey Satellite (TESS) sometimes exhibit a peak-bump light-curve morphology, characterized by a secondary, gradual peak well after the main, impulsive peak.

GRB Flares: UV/Optical Flaring (Paper I)
, 2013 We present a new algorithm for the detection of flares in gamma-ray burst (GRB) light curves and use this algorithm to detect flares in the UV/optical. The algorithm makes use of the Bayesian Information Criterion (BIC) to analyze the residuals of the fitted light curve, removing all major features, and to determine the statistically best fit to the ...

The optical polarization of the blazar PKS 2155–304 during an optical flare in 2010 [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT An analysis is presented of the optical polarimetric and multicolour photometric (BVRJ) behaviour of the blazar PKS 2155–304 during an outburst in 2010. This flare develops over roughly 117 d, with a flux doubling time τ ∼ 11 d, which increases from blue to red wavelengths.

Detection of second-order nonlinear optical magnetization by mapping normalized Stokes parameters [PDF]
, 2013 A measurable magnetic (nonlocal) contribution to the second harmonic generation (SHG) of nonmagnetic materials is an intriguing issue related to chiral materials, such as biomolecules.
