Meteorology of other planets in our solar system provides critical laboratories for testing our climate models, studying new weather mechanisms, and developing climate theories for other worlds. This particular paper discusses a method for identifying carbon dioxide clouds on Mars using infrared spectroscopy.
While theoreticians might work in many dimensions, observationalists must often do their analysis using very few. This paper presents observations of a classical nova from two types of spectrographs that determine a distance to the nova and a map of its morphology.
It is currently accepted that most, if not all, galaxies have a black hole smack dab in their center. These black holes are mind bogglingly massive – think millions to billions of suns! This paper focuses on whether the black holes grow before stars group on galactic scales to form the galaxy.
With the advent of large photometric surveys, Astronomers must often work through massive amounts of data. One solution to deal with these large numbers is to train computers to do the job. This paper discusses such a computer algorithm to select candidate quasi-stellar objects (QSOs), the bright nuclei of galaxies that each house a supermassive black hole.
Water plays an important role in the inter-stellar medium, but getting good spectra for star forming cores is difficult. A radio technique exploiting masers allows these authors to probe water in Cep E.
