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 ...
Gaps in Protoplanetary Disks as Signatures of Planets: I. Methodology and Validation

2012/2/23
We examine the observational consequences of partial gaps being opened by planets in protoplanetary disks. We model the disk using a static alpha-disk model with detailed radiative transfer, parametri...

2011/10/13
Data gaps are ubiquitous in spectral irradiance data, and yet, little effort has been put into finding robust methods for filling them. We introduce a data-adaptive and nonparametric method that allow...
