1. Arcetri Solar Physics Group: Solar Activity
Solar Activity at High Resolution . ... Solar Group . ... Researchers in Arcetri are involved in studies of solar activity at high temporal and spatial resolution, especially at photospheric and chromospheric levels. Our principal aim is to study the temporal correlation between the flares at coronal levels (e.g. hard X-rays emission) and the lower atmospheric signatures, mainly during the preflare and the impulsive phase. ...

4. Visitors Tourists -- The AO Optical Laboratory
At Arecibo we have a variety of optical instruments that we use to study terrestrial airglow emissions. ... As a complement to the airglow instrumentation we also maintain a set of optical instruments, called lidars, used for "active" remote sensing of the atmosphere. That is, we generate our own source signal using lasers and measure the characteristics of the light scattered back from the atmosphere. ... An operations manual for the Optical Laboratories is currently under major revision. ...

... Time-series of high resolution spectra have been obtained during three nights and several important events were detected. Observations contained several chromospheric lines, allowing to investigate simultaneously the response of the chromosphere at different heights. A detailed analysis of the H alpha line behaviour, in particular, has revealed prominece clouds and plage-like regions in this star. ... Promience clouds are seen to lie below the co-rotation radius. ...

13. Towards a General Definition for Spectroscopic Resolution
... Judged by their instrumental profiles, spectrometers fall into two basic classes---Lorentzian and Gaussian---with many other line profile functions (sinc functions, Voigt functions, Airy functions, etc.) falling into one of these two categories in some limit. We demonstrate that the Rayleigh, Sparrow, and Houston resolution criteria are of limited use compared to the ``equivalent width'' of the line profile. ... Rayleigh criterion. ... All of these functions have continuous higher derivatives. ...

15. Proposed Facility
... Clearly, what we need is big telescopes with high resolution spectrographs, to get good data on QSO absorption-lines. With bigger and better telescopes, you could measure the clustering and 3D distribution of gas in the early universe, by looking at lots of faint QSOs in the same parts of the sky. ... With the high resolutions made possible by big telescopes, you could look at the internal velocity structure of the absorbing clouds. ...
