Electron temperature relations and the direct N, O, Ne, S and Ar abundances of 49959 star-forming galaxies in DESI Data Release 2
D. Scholte, F. Cullen, J. Moustakas +42
We present the largest direct-method abundance catalogue of galaxies to date, containing measurements of 49959 star-forming galaxies at z < 0.96 from DESI Data Release 2. By direct…
Shocks and complex chemodynamics in the metal-poor starburst galaxy CGCG 007-025 revealed through high-resolution echelle spectroscopy
Macarena G. del Valle-Espinosa, Vital Fernández, Rubén Sánchez-Janssen +3
We use Magellan/MIKE echelle spectroscopy to conduct an in-depth chemodynamical analysis of the most luminous star-forming region within the metal-poor starburst dwarf galaxy CGCG…
Direct estimates of nitrogen abundance for Seyfert 2 nuclei
O. L. Dors, M. V. Cardaci, G. F. Hägele +10
We derive the nitrogen and oxygen abundances in the Narrow Line Regions (NLRs) of a sample of 38 local () Seyfert~2 nuclei. For that, we consider narrow optical emis…
The JWST EXCELS survey: Too much, too young, too fast? Ultra-massive quiescent galaxies at 3 < z < 5
A. C. Carnall, F. Cullen, R. J. McLure +21
We report ultra-deep, medium-resolution spectroscopic observations for 4 quiescent galaxies with log at . These data were obtained with J…
Quiescent or dusty? Unveiling the nature of extremely red galaxies at
L. Barrufet, P. Oesch, R. Marques-Chaves +15
The advent of the JWST has revolutionised our understanding of high-redshift galaxies. In particular, the NIRCam instrument on-board JWST has revealed a population of Hubble Space…
JWST PRIMER: A new multi-field determination of the evolving galaxy UV luminosity function at redshifts
C. T. Donnan, R. J. McLure, J. S. Dunlop +18
We present a new determination of the evolving galaxy UV luminosity function (LF) over the redshift range using a combination of several major Cycle-1 JWST imaging pro…
The ultraviolet continuum slopes of high-redshift galaxies: evidence for the emergence of dust-free stellar populations at z > 10
F. Cullen, D. J. McLeod, R. J. McLure +11
We present an analysis of the ultraviolet (UV) continuum slopes () for a sample of galaxy candidates at selected from a combination of JWST NI…
Everything that glitters is not gold: V1315 Cas is not a dormant black hole
J. Zak, D. Jones, H. M. J. Boffin +11
The quest for quiet or dormant black holes has been ongoing since several decades. Ellipsoidal variables possibly indicate the existence of a very high-mass invisible companion and…
New quantitative nitrogen abundance estimations in a sample of Seyfert 2 Active Galactic Nuclei
O. L. Dors, K. Z. Arellano-Cordova, M. V. Cardaci +1
We obtained new quantitative determinations of the nitrogen abundance and a consistent relation between nitrogen and oxygen abundances for a sample of Seyfert 2 galaxies located at…
