JWST Reveals Compact Nuclear Starbursts Masquerading as AGNs in Metal-Poor Dwarfs: Where Are the Accreting Intermediate-Mass Black Holes?
William Matzko, Shobita Satyapal, Jeffrey D. Mckaig +19
We present JWST/NIRSpec spectroscopy of the low-mass, metal-poor galaxy SDSS~J160135.95+311353.7 (J1601), selected for its extreme mid-infrared colors and compact nuclear emission,…
Little Red Dots on FIRE: Exploring the formation and observational signatures of ultra-compact early galaxies
Niranjan Chandra Roy, Daniel Anglés-Alcázar, Rachel K. Cochrane +15
Little Red Dots (LRDs) are compact sources with broad Balmer lines, Balmer breaks, anomalous UV emission, rising red continuum, and uncertain origin. We use FIRE cosmological simul…
JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5: Photometric Catalog
Brant E. Robertson, Benjamin D. Johnson, Sandro Tacchella +34
JADES Data Release 5 (DR5) photometric catalogs and describes the methodologies used for source detection, deblending, photometry, uncertainty estimation, and catalog curation. The…
Is Crater II disrupting?
A. Katherina Vivas, Alistair Walker, Clara MartÃnez-Vázquez +5
Crater~II (CraII) is a very intriguing, low-surface brightness and extended galaxy in the vicinity of our Milky Way. Motivated by its huge area and the number of RR Lyrae stars (RR…
Observation of Ion-wave Satellites to Laser Harmonics in Intense Picosecond Laser-Solid Interaction
R. S. Marjoribanks, L. Zhao, F. W. Budnik +5
Detailed spectra of harmonics produced from ultra-intense, sub-picosecond, high-contrast laser pulses incident on solid targets have shown the first observation of regular red- and…
Investigating photometric and spectroscopic variability in the multiply-imaged Little Red Dot A2744-QSO1
Lukas J. Furtak, Amy R. Secunda, Jenny E. Greene +25
JWST observations have uncovered a new population of red, compact objects at high redshifts dubbed `Little Red Dots' (LRDs), which typically show broad emission lines and are thoug…
