Remote probing ofD-region irregularities

Observation ofD D Oscillations

We report a measurement of the time-dependent ratio of D ! Kþ to D ! K þ decay rates in D þ-tagged events using 1:0 fb 1 of integrated luminosity recorded by the LHCb experiment. We measure the mixing parameters x02 1⁄4 ð 0:9 1:3Þ 10 , y0 1⁄4 ð7:2 2:4Þ 10 , and the ratio of doubly-Cabibbo-suppressed to Cabibbo-favored decay rates RD 1⁄4 ð3:52 0:15Þ 10 , where the uncertainties include statistic...

Probing the Photodissociation Region toward Hd 200775

The illuminating source of the photodissociation region associated with the reÑection nebula NGC 7023 is HD 200775. We probed the foreground atomic and molecular material through diagnostics observed in absorption against the background star. Ground-based measurements of Na I, K I, and Ca II and of the molecules CH, CH`, and CN were analyzed in order to extract the physical conditions 2 for thi...

Incoherent and Coherent Cw Laser Systems for Remote Atmospheric Probing

This report summarizes typical laser systems now available for atmospheric probing. Experiments comparing coherent and incoherent receiving techniques are described and typical performance data presented.

Inner Workings: Probing cosmic mysteries in a remote desert.

Amid the volcanic range of the windy, otherworldly Atacama Desert, a telescope collects ancient light from the cloudless sky. The international team of cosmologists manning the instrument hopes it will illuminate the conditions of the universe just after its dawn 13.8 billion years ago. Most physicists believe that the universe inflated rapidly, just a fraction of a nanosecond after it came int...
