Abstract Jean Tarde and Jan Smogulecki carried out sunspot observations in the 1610s 1620s at dawn of telescopic era. We analysed their original observational records to revise sunspot-group numbers existing database. In this study, we provide a new counting as basis for future scientific discussions. Furthermore, compared Smogulecki’s with those Scheiner Schönberger on same observation days. a...

We present the first tentative detection of spinning dust emission from specific astronomical sources. All other detections in the current literature are statistical. The Green Bank 140 foot telescope was used to observe 10 dust clouds at 5, 8, and 10 GHz. In some cases, the observed emission was consistent with the negative spectral slope expected for free-free emission (thermal bremsstrahlung...

Bacteriorhodopsin is a rhodopsin-like protein found in the cell membrane of Halobacterium halobium. It shows an absorption maximum at 570 nm and, in the light, undergoes cyclic spectral changes which include a relatively long-lived complex absorbing maximally at 412 nm. Excitation profiles have been obtained with several laser frequencies for two vibrations in the resonance Raman spectrum of ba...
