Anisotropic reflectance of Arctic snow and sea ice
(The University of Bergen, 2017-12-21)We present an investigation of the angular distribution of reflected light on snow and sea ice, for three selected wavelengths; 500, 800 and 1100 nm. Our analysis covers how the angular reflectance distribution is affected ...Master thesis -
Anomalous evolution of the near-side jet peak shape in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV
(American Physical Society, 2017-09-08)The measurement of two-particle angular correlations is a powerful tool to study jet quenching in a $p_{\mathrm{T}}$ region inaccessible by direct jet identification. In these measurements pseudorapidity ($\Delta\eta$) and ...Journal article -
