Here Be SDRAGNs - Spiral Galaxies Hosting Large Double Radio Sources
Jean Tate, William C. Keel, Michael O'Keeffe +16
We present a sample of large double radio sources hosted by spiral galaxies (Spiral Double Radio Active Galactic Nuclei, SDRAGNs). Candidates were selected during Radio Galaxy Zoo,…
Overlap Zoo Beta: A Catalogue of ~800 Occulting Pairs in the DESI Legacy Survey using Citizen Science
T. Butrum, B. Holwerda, W. C. Keel +11
Overlapping galaxies, in which a foreground galaxy partially overlaps a background galaxy, offer a unique opportunity to measure dust attenuation, a key nuisance parameter in galax…
Globular Clusters in the Galaxy Cluster MACS0416 at z = 0.397
Jessica M. Berkheimer, Rogier A. Windhorst, William E. Harris +27
We present a photometric analysis of globular clusters (GCs) in the massive galaxy cluster MACS J0416.1-2403 (z = 0.397) using deep JWST/NIRCam imaging from the PEARLS program. PSF…
JWST's PEARLS: A z=6 quasar in a train-wreck galaxy merger system
Madeline A. Marshall, Rogier A. Windhorst, Giovanni Ferrami +35
We present JWST NIRSpec integral field spectroscopy observations of the z=5.89 quasar NDWFS J1425+3254 from 0.6-5.3 microns, covering the rest-frame ultraviolet and optical at a sp…
The luminosity history of fading local quasars over 10 years as observed by VLT/MUSE
C. Finlez, E. Treister, F. Bauer +10
We present a comprehensive study of five nearby active galaxies featuring large (tens of kpc) extended emission-line regions (EELRs). The study is based on large-format integral fi…
A Demonstration of Interstellar Navigation Using New Horizons
Tod R. Lauer, David H. Munro, John R. Spencer +51
As NASA's New Horizons spacecraft exits the Solar System bound for interstellar space, it has traveled so far that the nearest stars have shifted markedly from their positions seen…
