Observations of High Galactic Latitude Line and Continuum Emission (912 - 1600 Å) with New Horizons
Jayant Murthy, James Overduin, Seth Redfield +5
We present observations of the cosmic ultraviolet background (CUVB) from 912 - 1600 A using the Stem aperture of the Alice spectrograph on the New Horizons spacecraft at 56 AU from…
A Critical UV Legacy: A Hubble Roadmap for HWO Science Readiness
Sarah Peacock, Aiden S. Zelakewicz, Lisa Kaltenegger +14
The Habitable Worlds Observatory (HWO) will provide the first opportunity to directly image and spectrally characterize terrestrial exoplanets in the habitable zones of nearby star…
The unique ability of the Hubble Space Telescope to characterize young exoplanet environments
Keighley E. Rockcliffe, Allison Youngblood, Kevin France +10
The chemical and mass evolution of exoplanet atmospheres is shaped by their specific X-ray through ultraviolet (5 - 3200 Angstroms) irradiance history. X-ray and EUV (5 - 911 Angst…
First Resolution of a Main Sequence G-Star Astrosphere Using Chandra
C. M. Lisse, S. J. Wolk, B. Snios +24
We report resolution of a halo of X-ray line emission surrounding the Zero Age Main Sequence (ZAMS) G8.5V star HD 61005 by Chandra ACIS-S. Located only 36.4 pc distant, HD 61005 is…
HWO Target Stars and Systems: A Survey of Archival UV and X-ray Data
Sarah Peacock, David J. Wilson, Tyler Richey-Yowell +14
We assess archival high-energy data for key stars on the Habitable Worlds Observatory (HWO) Target Stars and Systems 2025 list, as stellar radiation is critical to shaping and inte…
Toward a 2D H I Map of the Local Interstellar Medium
Allison Youngblood, Kevin France, Tommi Koskinen +9
Obtaining a complete census of gas in the local interstellar medium (<100 pc) is challenging given the limited available tracers of the warm, partially-ionized medium. Medium-to-hi…
AAS Graduate Admissions Task Force: Final report and recommendations
Emily M. Levesque, Rachel Ivie, Christopher Johns-Krull +7
In March of 2024 the AAS formed our Graduate Admissions Task Force (GATF), asking us to produce recommendations aimed at improving the state of graduate admissions in astronomy. Th…
The Case for High Resolution Spectroscopy in the Ultraviolet
Jeffrey L. Linsky, Todd M. Tripp, Seth Redfield +1
The Astro2020 Decadal Survey declared that the baryon cycle is one of the top-priority science topics for current astrophysics. Space instruments with both high spectral resolution…
The Origin of the Cluster of Local Interstellar Clouds
Catherine Zucker, Seth Redfield, Sara Starecheski +2
The interstellar medium within of the Sun consists of a complex of fifteen diffuse, partially ionized clouds. Located within the Local Bubble, these clouds, k…
Excess Ultraviolet Emission at High Galactic Latitudes: A New Horizons View
Jayant Murthy, J. Michael Shull, Marc Postman +11
We present new observations of the cosmic ultraviolet background (CUVB) at high Galactic latitudes (), made using the Alice UV spectrograph on board the New Horiz…
Astro2020 APC White Paper: Enabling Terminal Master's Degrees as a Step Towards a Ph.D
Michael B. Lund, Savannah R. Jacklin, David Ciardi
Earning any advanced degree in physics or astronomy is an arduous process and major accomplishment. However, not every journey to the Ph.D. is paved equally. Every year, there are…
