Identifying changing partial differential equations using Sampled Local WeakIdent
Wenbo Hao, Mengyi Tang, Sung Ha Kang
We propose Sampled Local WeakIdent (SLW-Ident), a framework for identifying changing governing equations from a single set of given data. Different from a typical approach of using…
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…
CCD Rotation Rates From Regular Dispersion Solution Monitoring
Matilde Mingozzi, Matthew Siebert
It has been previously studied that the STIS CCD exhibits a slow rotation, evident from changes in spectral traces and flat-field evolution. In this Instrument Science Report, we p…
Astronomical Advantages of a Boost Mission to Facilitate HST Science into the 2030s: Imaging the Circumgalactic Medium of Galaxies
Matthew J. Hayes, Kate H. R. Rubin, Michelle A. Berg +20
We present the case for imaging ultraviolet line emission from highly ionized metals and HI Lya in the circumgalactic medium of galaxies, should the Hubble Space Telescope receive…
High-S/N Quasar Observations with HST/COS: Deep Fields for Spectroscopy
Andrew J. Fox, Jerry Kriss, Philipp Richter +49
Hubble is still in prime observing condition for making transformative discoveries in UV astronomy. In this white paper we describe the science case for a deep (S/N>30) UV spectros…
The First Empirical Calibration of the MIR Abundance Diagnostic Ne with JWST
Noah S. J. Rogers, Evan D. Skillman, Danielle A. Berg +10
Large surveys of galaxies in the local and high-redshift Universe have, traditionally, relied on the intensity of rest-optical emission lines from metal ions in the Interstellar Me…
