TRICEPS. I. Tracing cold gas, dust, and stars at sub-kpc scales in massive star-forming galaxies at z = 4-5
Federico Lelli, Lingrui Lin, Zhi-Yu Zhang +11
We introduce the TRICEPS (Tracing Resolved Ionized Carbon Emission in Primeval Systems) survey. TRICEPS focuses on a sample of 16 massive galaxies at z = 4 - 5 with top-quality dat…
The gradual decline of Ly visibility in the CANDELS fields: evidence for the combined effects of galaxy evolution and reionization
L. Napolitano, L. Pentericci, A. Ferrara +35
We investigate the evolution of Ly visibility and the physical properties of Ly emitters (LAEs) across the five CANDELS fields using publicly available JWST/NIRSpec PRISM spe…
Euclid Quick Data Release (Q1). Searching for radio-selected \Euclid-dark galaxies in the EDF-N
Euclid Collaboration, M. Giulietti, I. Prandoni +308
We present and investigate the properties of a sample of radio-selected, Euclid-dark galaxies, identified from LOFAR HBA observations at 144 MHz within the Euclid Deep Field-North…
The quasi-star model for Little Red Dots: potential and challenges
Fabrizio Gentile, Mauro Giavalisco, Emanuele Daddi +25
(Abridged) Little Red Dots (LRDs) are a class of sources discovered by JWST observationally defined by a "V-shaped" rest-frame UV-Optical SED, a compact or unresolved morphology, a…
A Rapid Evolution in the Observed Mbh/M* Relation at z > 3 Revealed via Spectro-photometric SED-Modeling
Ansh R. Gupta, Anthony Taylor, Emma Curtis-Lake +33
Spectroscopic observations from JWST have uncovered a plethora of active galactic nuclei (AGN) at z > 4 with black hole (BH) mass (Mbh) to stellar mass (M*) ratios significantly ab…
Beyond the [OIII]4363 auroral line: [NeIII]3868 as a direct tracer of electron temperature
Borja Pérez-Díaz, José M. Vílchez, Marco Castellano +9
Auroral lines enable accurate measurements of chemical abundances in ionized gaseous nebulae thanks to their sensitivity to electron temperature. However, metal-enriched systems re…
An empirical derivation of the average dust attenuation law at 2<z<7
Giulia Rodighiero, Gaia Edes Esposito, Daniela Calzetti +12
Dust attenuation affects galaxy SEDs and introduces uncertainties in star formation rates, stellar masses, and metallicities. Direct spectroscopic constraints at early cosmic epoch…
EGS-z11-R0: a red, dust-rich galaxy at Cosmic Dawn
Giulia Rodighiero, Andrea Ferrara, Michele Catone +16
Context. Galaxies discovered by JWST at z > 10 are predominantly characterized by extremely blue rest-frame UV slopes. Conversely, the existence of dust-reddened systems at such ea…
The Collective Voice of Ly Emitters: Insights from JWST Stacked Spectroscopy
R. Tripodi, L. Napolitano, L. Pentericci +20
We present a spatially resolved stacked analysis of 287 LAEs at observed with JWST/NIRSpec prism spectroscopy. By constructing a two-dimensional stack from public surveys (CA…
A Morphology Catalog of Galaxies in CEERS: Evolution in the Size and Color Gradients of Galaxies Since Cosmic Dawn
Elizabeth J. McGrath, Steven L. Finkelstein, Guillermo Barro +42
We present measurements of morphological parameters from fitting 53,885 galaxies detected to a magnitude limit of F356W in the CEERS NIRCam imaging with galfit in six broad…
Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity
Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +61
We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…
From "The Cliff" to "Virgil": Mapping the Spectral Diversity of Little Red Dots with JWST/NIRSpec
Guillermo Barro, Pablo G. Perez-Gonzalez, Dale Kocevski +26
One of JWST's most unexpected discoveries is the emergence of "Little Red Dots'' (LRDs): compact sources at with blue rest-frame UV continua, red optical slopes, and…
