Identifying Cosmic Ray Over-Flagging in STIS CCD Spectroscopic Observations
Matthew M. Dallas, Sean Lockwood
The standard method for rejecting cosmic rays in CCD data taken by the Hubble Space Telescope's Space Telescope Imaging Spectrograph (STIS) instrument relies on combining multiple…
When Do Discrete Actions Make Good Continuous Controllers?
Zeji Yi, Soham Dasgupta, Xinyang Zhang +5
Though modern AI models like LLMs predict discrete tokens, today's robotic foundation models represent actions as continuous vectors. In this paper, we challenge this common consen…
Wavelength Calibration Accuracy Across the STIS CCD: Pipeline Update and User Guidance
Matilde Mingozzi, Robert Jedrzejewski, Matthew Siebert +3
We investigate the wavelength calibration accuracy of STIS CCD spectra as a function of detector position, focusing on the E1/E2 pseudo-apertures. Comparison between measured lamp…
Barycentric Corrections for HST/STIS Data
Joshua D. Lothringer, Joleen K. Carlberg, Sean Lockwood
We describe $\texttt{stistools.barycentric_correction}$, a new Python utility for calculating barycentric timing corrections for HST/STIS observations. This tool replaces the depre…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
The Tarantula Massive Binary Monitoring: I. Observational campaign and OB-type spectroscopic binaries
L. A. Almeida, H. Sana, W. Taylor +24
Massive binaries (MBs) play a crucial role in the Universe. Knowing the distributions of their orbital parameters (OPs) is important for a wide range of topics, from stellar feedba…
The non-uniform, dynamic atmosphere of Betelgeuse observed at mid-infrared wavelengths
V. Ravi, E. H. Wishnow, C. H. Townes +3
We present an interferometric study of the continuum surface of the red supergiant star Betelgeuse at 11.15 microns wavelength, using data obtained with the Berkeley Infrared Spati…
The many faces of Betelgeuse
V. Ravi, E. H. Wishnow, S. Lockwood +1
The dynamics of the surface and inner atmosphere of the red supergiant star Betelgeuse are the subject of numerous high angular resolution and spectroscopic studies. Here, we prese…
