Solar Slitless Spectroscopy with Learned Reconstruction

The Astrophysical Journal
Although solar imaging spectroscopy has been widely used to study the Sun, the inherent rastering process in conventional slit spectrographs required to generate spatial-spectral images limits their capability for studying dynamic events.

JWST high-contrast spectroscopy with speckle modelling: Atmospheric retrievals of the T-dwarf companion HD 19467 B

Astronomy & Astrophysics
Context. High-contrast medium-resolution spectroscopy with JWST can resolve molecular and isotopic features in cool substellar atmospheres, but for close-in companions, the extracted spectra can be biased by wavelength-dependent residual stellar ...

Abundance Diagnostics from a Slitless Imaging Spectrometer: A Proof-of-concept for MaGIXS-2

The Astrophysical Journal
Elemental abundance diagnostics in the solar corona are crucial for understanding energy transport, plasma heating, and magnetic activity. Most earlier imaging-spectroscopic studies have relied on slit-based spectrometers, which offer high spectral ...
