Signal processing and data acquisition system for the BTO detectors onboard COSI
Shunsaku Nagasawa, Tadayuki Takahashi, Kazuhiro Nakazawa +15
The energy range from a few hundred keV to a few MeV includes important probes such as nuclear gamma-rays and the 511 keV annihilation line. However, compared to X-rays and GeV/TeV…
The Compton Spectrometer and Imager
John A. Tomsick, Steven E. Boggs, Andreas Zoglauer +72
The Compton Spectrometer and Imager (COSI) is a NASA Small Explorer (SMEX) satellite mission in development with a planned launch in 2027. COSI is a wide-field gamma-ray telescope…
Observations of Thomson scattering from a loop-prominence system
Juan Carlos Martínez Oliveros, Juan Camilo Guevara Gómez, Pascal Saint-Hilaire +2
We describe observations of the white-light structures in the low corona following the X8.2 flare SOL2017-09-10, as observed in full Stokes parameters by the Helioseismic and Magne…
Tracking a beam of electrons from the low solar corona into interplanetary space with the Low Frequency Array, Parker Solar Probe and 1 au spacecraft
Samuel T. Badman, Eoin P. Carley, Luis Alberto Cañizares +7
Type III radio bursts are the result of plasma emission from mildly relativistic electron beams propagating from the low solar corona into the heliosphere where they can eventually…
Periodicities in an active region correlated with Type III radio bursts observed by Parker Solar Probe
Cynthia Cattell, Lindsay Glesener, Benjamin Leiran +5
Context. Periodicities have frequently been reported across many wavelengths in the solar corona. Correlated periods of ~5 minutes, comparable to solar p-modes, are suggestive of c…
Statistics and Polarization of Type III Radio Bursts Observed in the Inner Heliosphere
Marc Pulupa, Stuart D. Bale, Samuel T. Badman +20
We present initial results from the Radio Frequency Spectrometer (RFS), the high frequency component of the FIELDS experiment on the Parker Solar Probe (PSP). During the first PSP…
Magnetic connectivity of the ecliptic plane within 0.5 AU : PFSS modeling of the first PSP encounter
Samuel T. Badman, Stuart D. Bale, Juan C. Martinez Oliveros +19
We compare magnetic field measurements taken by the FIELDS instrument on Parker Solar Probe (PSP) during its first solar encounter to predictions obtained by Potential Field Source…
An in-situ interplanetary "U-burst": Observation and results
Juan Carlos Martínez-Oliveros, Saida Milena Diaz Castillo, Vratislav Krupar +3
We report and examine the observation of an unusual and rare in-situ electron observation associated with a solar type III radio burst on 24 December 1996. This radio event was acc…
A statistical correlation of sunquakes based on their seismic, white light, and X-ray emission
J. C. Buitrago-Casas, J. C. Martinez Oliveros, C. Lindsey +4
Several mechanisms have been proposed to explain the transient seis- mic emission, i.e., sunquakes, from some solar flares. Some theories associate high-energy electrons and/or whi…
Chromospheric and Coronal Observations of Solar Flares with the Helioseismic and Magnetic Imager
Juan-Carlos Martínez Oliveros, Säm Krucker, Hugh S. Hudson +7
We report observations of white-light ejecta in the low corona, for two X-class flares on the 2013 May 13, using data from the Helioseismic and Magnetic Imager (HMI) of the Solar D…
Transient artifacts in a flare observed by the Helioseismic and Magnetic Imager on the Solar Dynamics Observatory
J. C. Martínez Oliveros, C. Lindsey, H. S. Hudson +1
The Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) provides a new tool for the systematic observation of white-light flares, including Doppler…
The Role of Magnetic Fields in Transient Seismic Emission Driven by Atmospheric Heating in Flares
C. Lindsey, A. -C. Donea, J. C. Martinez Oliveros +1
The physics of transient seismic emission in flares remains largely mysterious. Its discoverers proposed that these "sunquakes" are the signature of a shock driven by "thick-target…
The height of a white-light flare and its hard X-ray sources
Juan-Carlos Martínez Oliveros, Hugh S. Hudson, Gordon J. Hurford +6
We describe observations of a white-light flare (SOL2011-02-24T07:35:00, M3.5) close to the limb of the Sun, from which we obtain estimates of the heights of the optical continuum…
The 2010 August 01 type II burst: A CME-CME Interaction, and its radio and white-light manifestations
Juan Carlos Martínez Oliveros, Claire L. Raftery, Hazel M. Bain +4
We present observational results of a type II burst associated with a CME-CME interaction observed in the radio and white-light wavelength range. We applied radio direction-finding…
Imaging Spectroscopy of a White-Light Solar Flare
J. C. Martinez Oliveros, S. Couvidat, J. Schou +4
We report observations of a white-light solar flare (SOL2010-06-12T00:57, M2.0) observed by the Helioseismic Magnetic Imager (HMI) on the Solar Dynamics Observatory (SDO) and the R…
