Ionized Nebulae Around Two New Symbiotic Stars: GR Cygni and [D75] 141
Howard E. Bond, Calvin Carter, Sven E. Eklund +4
In the course of selecting targets for a spectroscopic survey of faint planetary-nebula nuclei, we encountered two anomalous cases of late-type variable stars surrounded by nebulos…
Implications of Broad [O III] 4364 and UV Line Emission in Two Little Red Dots at z ~ 7 - 8
Casey Papovich, Kaila Ronayne, Weida Hu +17
We present deep, NIRSpec G140M and G395M spectroscopy of Little Red Dots (LRDs) at z = 6.68 and z = 8.35. Both LRDs show broad Balmer and [O III] 4364 emission. The broad [O III…
XRISM Resolves the Circum-nuclear Environment of NGC 4945
Peter G. Boorman, Poshak Gandhi, Yoshihiro Ueda +31
Compton-thick Active Galactic Nuclei (AGN) represent one of the most elusive phases of massive black hole growth, yet are expected to contribute substantially to the Cosmic X-ray B…
From Images to Orbits: A Hubble 2030s Astrometric Legacy for the M31-M33 Star Cluster Systems
Borja Anguiano, Benjamin J. Gibson, Sten Hasselquist
The most irreplaceable capability of HST in the 2030s is not only its angular resolution or its UV--optical sensitivity, but its accumulated time baseline. We recommend a Hubble Lo…
The Effect of External Photoevaporation on the Disk Fraction in M17
Samuel Millstone, Megan Reiter, Morten Andersen +6
A major obstacle to improving models of planet formation is understanding how the local environment influences the lifetime of the disks in which they form. The spread in observed…
Spectroscopic Survey of Faint Planetary-Nebula Nuclei. VIII. The Dwarf Barium Central Star of Kohoutek 1-9
Howard E. Bond, Peter Goodhew, Daniel Stern +2
In the course of our ongoing survey of faint planetary-nebula nuclei (PNNi), we obtained optical spectroscopy of the central star of the little-studied PN Kohoutek~1-9 (K 1-9). Its…
