PRISMS/U13151. A Glimpse into the Earliest Phases of Galaxy Formation through an Ultra-Faint System 500 Myr after the Big Bang
Pierluigi Rinaldi, Javier Álvarez-Márquez, Alejandro Crespo Gómez +35
Detailed UV-to-optical studies of galaxies at z >= 10 have largely focused on bright systems (MUV <= -20 mag), leaving intrinsically faint galaxies virtually unexplored to date. Co…
Dissecting the Obscured Core of GN20: an Active Galactic Nucleus Outshone by Young Stars
M. Hamed, L. Colina, P. G. Pérez-González +17
We investigate the relative contributions of star formation and AGN activity to the total energy budget of GN20, one of the most luminous dusty star-forming galaxies known at …
A stellar bar hidden in an extreme gas-rich disk galaxy at z=4.055
Leindert A. Boogaard, Luca Costantin, Thor Tepper-García +14
The classical picture for the formation of stellar bars -- key dynamical drivers of the evolution of galaxies -- is through secular evolution of instability in gas poor, stellar-do…
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…
There Is More to Outshining: 2D Dust Effects on Stellar Mass Estimates at with JWST in the JADES Field
M. Hamed, P. G. Pérez-González, M. Annunziatella +15
Dust attenuation modifies the observed spectral energy distribution (SED), leading to biases in the properties inferred from integrated SED fitting. As spatially resolved SED model…
GA-NIFS: AGN activity in a Lyα emitter within a triple-AGN system anchored by a passive galaxy at z=3
Michele Perna, Santiago Arribas, Mahmoud Hamed +15
Massive quenched galaxies at z>3 challenge models of early galaxy evolution, as their rapid formation and abrupt quenching require efficient feedback, often linked to active galact…
The rise of the galactic empire: luminosity functions at and estimated with the MIDISNGDEEP ultra-deep JWST/NIRCam dataset
Pablo G. Pérez-González, Göran Östlin, Luca Costantin +39
We present a sample of six F200W and three F277W dropout sources identified as galaxy candidates using the deepest JWST/NIRCam data to date (5 depths mag at…
The ALPINE-ALMA [CII] Survey: Unveiling the baryon evolution in the ISM of star-forming galaxies
P. Sawant, A. Nanni, M. Romano +28
Recent observations reveal a rapid dust build-up in high-redshift galaxies (z > 4), challenging current models of galaxy formation. While our understanding of dust production and d…
Evidence of extended [CII] and dust emission in local dwarf galaxies
M. Romano, D. Donevski, Junais +8
The evolution of dwarf galaxies is dramatically affected by gaseous and dusty outflows, which can easily deprive their interstellar medium of the material needed for the formation…
Attenuation proxy hidden in surface brightness-colour diagrams. A new strategy for the LSST era
K. Małek, Junais, A. Pollo +22
Large future sky surveys, such as the LSST, will provide optical photometry for billions of objects. This paper aims to construct a proxy for the far ultraviolet attenuation (AFUVp…
A comparative study of the fundamental metallicity relation: the impact of methodology on its observed evolution
F. Pistis, A. Pollo, M. Figueira +10
We used 5487 star-forming galaxies at redshift z~0.63 extracted from the VIPERS and 143774 comparison galaxies in the local Universe from the GSWLC catalog. We employed two familie…
X-ray luminosity-star formation rate scaling relation: Constraints from the eROSITA Final Equatorial Depth Survey (eFEDS)
G. Riccio, G. Yang, Małek +7
We present measurements of the relation between X-ray luminosity and star formation activity for a sample of normal galaxies spanning the redshift range between 0 and 0.25. We use…
Decoding the IRX-β dust attenuation relation in star-forming galaxies at intermediate redshift
M. Hamed, F. Pistis, M. Figueira +11
We aim to understand what drives the IRX-βdust attenuation relation at intermediate redshift (0.5 < z < 0.8) in star-forming galaxies. We investigate the role of various galaxy pro…
Variation of optical and infrared properties of galaxies with their surface brightness
Junais, K. Małek, S. Boissier +12
Although low surface brightness galaxies (LSBs) contribute a large fraction to the number density of galaxies, their properties are still poorly known. LSBs are often considered du…
The slippery slope of dust attenuation curves: Correlation of dust attenuation laws with star-to-dust compactness up to z = 4
M. Hamed, K. Małek, V. Buat +5
Aims. We investigate dust attenuation of 122 heavily dust-obscured galaxies detected with the Atacama Large Millimeter Array (ALMA) and Herschel in the COSMOS field. We search for…
SFR estimations from z=0 to z=0.9 -- A comparison of SFR calibrators for star-forming galaxies
M. Figueira, A. Pollo, K. Małek +7
Using VIPERS, we estimated a set of SFR based on photometric and spectroscopic data. We used, as estimators, photometric bands from ultraviolet to mid-infrared, and spectral lines.…
Getting ready for the LSST data -- estimating the physical properties of main sequence galaxies
Gabriele Riccio, Katarzyna Małek, Ambra Nanni +8
In this work we study how to employ the upcoming Legacy Survey of Space and Time (LSST) data to constrain physical properties of normal, star forming galaxies. We use simulated LSS…
Multiwavelength dissection of a massive heavily dust-obscured galaxy and its blue companion at z 2
M. Hamed, L. Ciesla, M. Béthermin +4
In this work we study a system of two galaxies, Astarte and Adonis, at z 2 when the Universe was undergoing its peak of star formation activity. Astarte is a dusty star-form…
