The AGN nature of strong CIII emitters in the Early Universe with JWST
F. Arevalo-Gonzalez, R. Tripodi, M. Llerena +21
The semi-forbidden CIII] 1907,1909 doublet is a key tracer of high-ionization emission in the early universe. We present a study of CIII] emission in galaxies at z=5-7, using p…
HELM's deep: Highly Extincted Low-Mass galaxies seen by JWST
L. Bisigello, G. Gandolfi, A. Grazian +25
The dust content of star-forming galaxies is generally positively correlated with their stellar mass. However, some recent JWST studies have shown the existence of a population of…
Chemical enrichment in LINERs from MaNGA. II. Characterizing the shape of their radial metallicity gradients
Borja Pérez-Díaz, José M. Vílchez, Enrique Pérez Montero +3
Chemical abundance radial gradients provide key information on how the processes that affect chemical enrichment of the gas-phase interstellar medium (ISM) act at different galaxy…
VENUS: When Red meets Blue -- A multiply imaged Little Red Dot with an apparent blue companion behind the galaxy cluster Abell 383
Miriam Golubchik, Lukas J. Furtak, Joseph F. V. Allingham +50
We report the discovery of a doubly-imaged Little Red Dot (LRD) candidate behind the galaxy cluster Abell 383, which we dub A383-LRD1. Initially classified as a dropout galaxy in H…
Resolving dust and Lyα emission in a lensed galaxy at the epoch of reionization with JWST/CANUCS
V. Markov, M. Bradač, V. Estrada-Carpenter +20
Lyman emission is highly sensitive to dust and neutral hydrogen and is therefore expected to be strongly suppressed in dusty or gas-rich galaxies during the epoch of reionizati…
Milky Way Globular Clusters: Nurseries for Dynamically-Formed Binary Black Holes
Federico Angeloni, Konstantinos Kritos, Raffaella Schneider +4
We present a novel self-consistent theoretical framework to characterize the formation, evolution, and merger sites of dynamically-formed black hole binaries, with a focus on expla…
