Abundance Diagnostics from Slitless Imaging Spectrometer: A Proof-of-Concept for MaGIXS-2
Biswajit Mondal, Amy R. Winebarger, P. S. Athiray
Elemental abundance diagnostics in the solar corona are crucial for understanding energy transport, plasma heating, and magnetic activity. Most earlier imaging-spectroscopic studie…
Spatial and Temporal Distribution of Nanoflare Heating During Active Region Evolution
Biswajit Mondal, James A Klimchuk, Amy R. Winebarger +2
Nanoflares are believed to be key contributors to heating solar non-flaring active regions, though their individual detection remains challenging. This study uses a data-driven fie…
Exploring the magnetic and thermal evolution of a coronal jet
Sushree S Nayak, Samrat Sen, Arpit Kumar Shrivastav +2
Coronal jets are the captivating eruptions which are often found in the solar atmosphere, and primarily formed due to magnetic reconnection. Despite their short-lived nature and lo…
A systematic study of inverting overlappograms: MaGIXS -- A case study
P. S. Athiray, Arthur Hochedez, Amy R Winebarger +1
Slitless (or wide field) imaging spectroscopy provides simultaneous imaging and spectral information from a wide field of view, which allows for rapid spectroscopic data collection…
Determining the nanoflare heating frequency of an X-ray Bright Point observed by MaGIXS
Biswajit Mondal, P. S. Athiray, Amy R. Winebarger +18
Nanoflares are thought to be one of the prime candidates that can heat the solar corona to its multi-million kelvin temperature. Individual nanoflares are difficult to detect with…
Can emission measure distributions derived from extreme-ultraviolet images accurately constrain high temperature plasma?
P. S. Athiray, Amy R. Winebarger
Measuring the relative amount of high-temperature, low-emission-measure plasma is considered to be a smoking gun observation to constrain the frequency of plasma heating in coronal…
The need for focused, hard X-ray investigations of the Sun
Lindsay Glesener, Albert Y. Shih, Amir Caspi +46
Understanding the nature of energetic particles in the solar atmosphere is one of the most important outstanding problems in heliophysics. Flare-accelerated particles compose a hug…
Role of small-scale impulsive events in heating the X-ray bright points of the quiet Sun
Biswajit Mondal, James A Klimchuk, Santosh V. Vadawale +6
Small-scale impulsive events, known as nanoflares, are thought to be one of the prime candidates that can keep the solar corona hot at its multi-million Kelvin temperature. Individ…
The First Flight of the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)
Sabrina L. Savage, Amy R. Winebarger, Ken Kobayashi +34
The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) sounding rocket experiment launched on July 30, 2021 from the White Sands Missile Range in New Mexico. MaGIXS is a unique…
On the faintest solar coronal hard X-rays observed with FOXSI
Juan Camilo Buitrago-Casas, Lindsay Glesener, Steven Christe +23
Solar nanoflares are small eruptive events releasing magnetic energy in the quiet corona. If nanoflares follow the same physics as their larger counterparts, they should emit hard…
