TL;DR: In this paper, the spectrum of a weak undulator field is calculated by going into a moving frame and the spectrum consists of one line with its width depending on the solid angle of the accepted radiation.

TL;DR: In this paper, the authors present HST images at 622 nm and 300 nm of the jet in 3C273 and determine the run of the optical spectral index at 0.2" along the jet.
Abstract: We present HST images at 622 nm and 300 nm of the jet in 3C273 and determine the run of the optical spectral index at 0.2" along the jet. The smoothness of spectral index changes shows that the physical conditions are varying smoothly across the jet. There is no correlation between the optical flux and spectral index, as would be expected for relativistic electrons suffering strong cooling due to synchrotron emission. We find no evidence for localized acceleration or loss sites. This suggests that the spectral shape is not changing much throughout the jet. We show that relativistic beaming and/or sub-equipartition magnetic fields cannot remove the discrepancy between light-travel time along the jet and the lifetime of electrons emitting optical synchrotron radiation. We consider this further evidence in favour of a distributed electron acceleration process.

TL;DR: In this article, a general Monte Carlo code for the simulation of X-ray fluorescence spectrometers is extended to predict the spectral response of instruments employing polarized exciting radiation, which is used for quantitative analysis of intermediate and massive samples.

TL;DR: In this paper, the first use of synchrotron radiation for circular dichroism (CD) measurements was described and the measurements were carried out in the wavelength range 1325-2050 A on (+)-3-methylcyclopentanone at the Synchrotrom Radiation Center of the University of Wisconsin-Madison.
