Gaps in the cloud cover? Comparing extinction measures in spiral disks
dust in galaxies spiral galaxies
2014/12/23
Dust in galaxies can be mapped either by the FIR/submillimeter emission, the optical or infrared reddening of starlight, or the extinction of a known background source. We compare two dust extinction ...
Measures of Star Formation Rates within Galaxies: the Impact of Diffuse Stellar Populations

2014/12/9
Thanks to the {\it Spitzer Space Telescope}, the infrared (IR) emission have been better studied in the past decades, as well as its relations to star formation rates (SFR) and the calibrations of IR ...

In this Letter I use the variation of the spread in rotation measure (RM) with Galactic latitude to separate the Galactic from the extragalactic contributions to RM. This is possible since the latter ...

2009/5/19
We propose a new method for the extraction of Rotation Measures
from spectral polarization data. The method is based on maximum
likelihood analysis and takes into account the circular nature of the ...
