The JWST-PRIMAL Legacy Survey. A JWST/NIRSpec reference sample for the physical properties and Lyman- absorption and emission of galaxies at
K. E. Heintz, G. B. Brammer, D. Watson +45
One of the surprising early findings with JWST has been the discovery of a strong "roll-over" or a softening of the absorption edge of Ly in a large number of galaxies at ($z\g…
The Large Magellanic Cloud stellar content with SMASH: I. Assessing the stability of the Magellanic spiral arms
T. Ruiz-Lara, C. Gallart, M. Monelli +23
The Large Magellanic Cloud (LMC) is the closest and most studied example of an irregular galaxy. Among its principal defining morphological features, its off-centred bar and single…
A broad-line quasar with unexplained extreme velocity offsets: post-shock outflow?
V. Rusakov, C. L. Steinhardt, M. Schramm +4
The quasar SDSS 0956+5128 exhibits three distinct velocity components with large offsets in emission: the systemic velocity of [O II], [O III] and [Ne III] narrow lines have redshi…
The impact of medium-width bands on the selection, and subsequent luminosity function measurements, of high-z galaxies
N. J. Adams, D. Austin, T. Harvey +7
New, ultra-deep medium-width photometric coverage with JWST's NIRCam instrument provides the potential for much improved photo-z reliability at high redshifts. In this study, we co…
Little red dots as young supermassive black holes in dense ionized cocoons
V. Rusakov, D. Watson, G. P. Nikopoulos +14
The James Webb Space Telescope (JWST) has uncovered many compact galaxies at high redshift with broad hydrogen and helium lines, including the enigmatic population of little red do…
Evidence of violation of Case B recombination in Little Red Dots
G. P. Nikopoulos, D. Watson, A. Sneppen +4
Little Red Dots (LRDs) are a new class of compact extragalactic objects, with a v-shaped optical spectral energy distribution breaking close to the Balmer break wavelength, and bro…
The bursty star formation history of the Fornax dwarf spheroidal galaxy revealed with the HST
V. Rusakov, M. Monelli, C. Gallart +4
We present a new derivation of the star formation history (SFH) of the dSph galaxy Fornax in two central regions, characterised by unprecedented precision and age resolution. It re…
Inside the cocoon: a comprehensive explanation of the spectra of Little Red Dots
A. Sneppen, D. Watson, J. H. Matthews +10
JWST has revealed a population of compact galaxies in the early Universe with broad emission lines and strong Balmer breaks; among them the so-called ''little red dots'' (LRDs). Th…
Outshining in the Spatially Resolved Analysis of a Strongly-Lensed Galaxy at z=6.072 with JWST NIRCam
C. Giménez-Arteaga, S. Fujimoto, F. Valentino +19
We present JWST/NIRCam observations of a strongly-lensed, multiply-imaged galaxy at , with magnification factors >~20 across the galaxy. We perform a spatially-resolved an…
