Filling the gap in the extragalactic census: A study at 21 cm and in the near -infrared
Galaxy The universe Optical detection The surface brightness system The Milky Way

Fundamental to a complete understanding of galaxy properties, formation, and evolution is a thorough knowledge of the local galaxy population. Until we understand the nearest, most easily detectable g...
A method for filling gaps in solar irradiance and in solar proxy data
method filling gaps solar irradiance solar proxy
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...
Estimates of Densities and Filling Factors from a Cooling Time Analysis of Solar Microflares Observed with RHESSI
Estimates Densities Filling Factors Solar Microflares
2011/10/12
We use more than 4,500 microflares from the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) microflare data set (Christe et al., 2008, Ap. J., 677, 1385) to estimate electron densities a...
