Elliptic flow contribution to two-particle correlations at different orientations to the reaction plane
Collective anisotropic particle flow, a general phenomenon present in
relativistic heavy-ion collisions, can be separated from direct
particle-particle correlations of different physics origin by virtue of its
specific azimuthal pattern. We provide expressions for flow-induced
two-particle azimuthal correlations, if one of the particles is detected under
fixed directions with respect to the reaction plane. We consider an ideal case
when the reaction plane angle is exactly known, as well as present the general
expressions in case of finite event-plane resolution. We foresee applications
for the study of generic two-particle correlations at large transverse momentum
originating from jet fragmentation.Comment: 5 pages, 3 figures, to be published as Rapid Communications in

Super-resolution microscopy of mitochondria.
Mitochondria, the powerhouses of the cell, are essential organelles in eukaryotic cells. With their complex inner architecture featuring a smooth outer and a highly convoluted inner membrane, they are challenging objects for microscopy. The diameter of mitochondria is generally close to the resolution limit of conventional light microscopy, rendering diffraction-unlimited super-resolution light microscopy (nanoscopy) for imaging submitochondrial protein distributions often mandatory. In this review, we discuss what can be expected when imaging mitochondria with conventional diffraction-limited and diffraction-unlimited microscopy. We provide an overview on recent studies using super-resolution microscopy to investigate mitochondria and discuss further developments and challenges in mitochondrial biology that might by addressed with these technologies in the future
