Noise in Maps of the Sun at Radio Wavelengths II: Solar Use Cases
Timothy Bastian, Bin Chen, Surajit Mondal +1
Noise in images of strong celestial sources at radio wavelengths using Fourier synthesis arrays can be dominated by the source itself, so-called self-noise. We outlined the theory…
Noise in Maps of the Sun at Radio Wavelengths I: Theoretical Considerations
Timothy Bastian, Bin Chen, Surajit Mondal +1
The Sun is a powerful source of radio emissions, so much so that, unlike most celestial sources, this emission can dominate the system noise of radio telescopes. We outline the the…
Radio Imaging Spectropolarimetry of CMEs and CME Progenitors
Bin Chen, Timothy S. Bastian, Sarah Gibson +8
Coronal mass ejections (CMEs) are the most important drivers of space weather. Central to most CMEs is thought to be the eruption of a bundle of highly twisted magnetic field lines…
Short-duration Radio Bursts with Apparent Extragalactic Dispersion
Pascal Saint-Hilaire, Arnold O. Benz, Christian Monstein
We present the results of the longest yet undertaken search for apparently extragalactic radio bursts at the Bleien Radio Observatory covering 21000 hours (898 days). The data were…
A decade of solar Type III radio bursts observed by the Nancay Radioheliograph 1998-2008
Pascal Saint-Hilaire, Nicole Vilmer, Alain Kerdraon
We present a statistical survey of almost 10 000 radio Type III bursts observed by the Nancay Radioheliograph from 1998 to 2008, covering nearly a full solar cycle. In particular,…
Statistically-derived flaring chromospheric-coronal density structure from non-thermal X-ray observations of the Sun
Pascal Saint-Hilaire, Sam Krucker, Robert P. Lin
For the first time, we have used RHESSI's spatial and energy resolution to determine the combined chromospheric and coronal density profile of the flaring solar atmosphere in a sta…
X-ray emission from the base of a current sheet in the wake of a CME
Pascal Saint-Hilaire, Sam Krucker, Robert P. Lin
Following a CME which started on 2002 November 26, RHESSI, the Ramaty High Energy Solar Spectroscopic Imager, observed for 12 hours an X-ray source above the solar limb, at altitud…
A Statistical Survey of Hard X-ray Spectral Characteristics of Solar Flares with Two Footpoints
Pascal Saint-Hilaire, Sam Krucker, Robert P. Lin
Using RHESSI data, we have analyzed some 172 hard X-ray peaks during 53 solar flares which exhibited a double-footpoint structure. Fitting both footpoints with power-laws, we find…
Allen Telescope Array Multi-Frequency Observations of the Sun
Pascal Saint-Hilaire, Gordon J. Hurford, Garrett Keating +2
We present the first observations of the Sun with the Allen Telescope Array (ATA). We used up to six frequencies, from 1.43 to 6 GHz, and baselines from 6 to 300 m. To our knowledg…
The RHESSI Microflare Height Distribution
Steven Christe, S Krucker, Pascal Saint-Hilaire
We present the first in-depth statistical survey of flare source heights observed by RHESSI. Flares were found using a flare-finding algorithm designed to search the 6-10 keV count…
