Dust in the Smith Cloud? A UV Investigation into the Smith Cloud's Gas-Phase Abundance Patterns
Johanna Vazquez, Kathleen Barger, Frances Cashman +11
The Smith Cloud is a high-velocity cloud (HVC) on its final approach to the Milky Way that shows evidence of interaction with the Galaxy's disk. We investigate the metallicity and…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Unique Astrophysics in the Lyman Ultraviolet
Jason Tumlinson, Alessandra Aloisi, Gerard Kriss +24
There is unique and groundbreaking science to be done with a new generation of UV spectrographs that cover wavelengths in the "Lyman Ultraviolet" (LUV; 912 - 1216 Ang). There is no…
X-shooter, NACO, and AMBER observations of the LBV Pistol Star \footnote{Based on ESO runs 85.D-0182A, 085.D-0625AC}
Christophe Martayan, Ronny Blomme, Jean-Baptiste Le Bouquin +15
We present multi-instruments and multi-wavelengths observations of the famous LBV star Pistol Star. These observations are part of a larger program about early O stars at different…
The Abundance of Deuterium in the Warm Neutral Medium of the Lower Galactic Halo
Blair Savage, Nicolas Lehner, Andrew Fox +2
We use high resolution spectra obtained with FUSE and STIS to obtain interstellar column densities of H I, D I, O I, S II, Fe II and P II toward the QSO HE 0226-4110 ( l = 253.4 de…
Towards Cumulative Abstract Semantics via Handlers
Cade Lueker, Andrew Fox, Bor-Yuh Evan Chang
We consider the problem of modularizing control flow in a generic abstract interpretation framework. A generic abstract interpretation framework is not truly flexible if it does no…
