CO observations in NGC 2359: the molecular cloud revisited
(IOP Publishing, 2001-06)
Based on CO (2-1) observations obtained with the Swedish-ESO Submillimeter Telescope, the distribution of molecular material associated with the Wolf-Rayet ring nebula NGC 2359 has been determined. The angular resolution ...
Some interesting challenges of New Physics in Space
(Centro Brasileiro de Pesquisas FísicasRio de Janeiro, 2013)
I discuss briefly nine interesting
challenges that I studied over the
years, that could be studied in
greater detail now (in alphabetical
order).
(1) ACCELERATION OF COSMIC RAYS:
Not by the generally assumed ...
Deformed microbial mat structures in a semiarid temperate coastal setting
(Elsevier Science, 2015-06)
This study focuses on sedimentary structures formed by microbial consortia, in a particular coastal setting, an ancient tidal channel, separated from the ocean by a sandy spit and connected by a blind tidal channel at the ...
