Clumpy star formation and an obscured nuclear starburst in the luminous dusty z=4 galaxy GN20 seen by MIRI/JWST
A. Bik, J. Álvarez-Márquez, L. Colina +28
Dusty star-forming galaxies emit most of their light at far-IR to mm wavelengths as their star formation is highly obscured. Far-IR and mm observations have revealed their dust, ne…
Uncovering the MIR emission of quiescent galaxies with
David Blánquez-Sesé, G. E. Magdis, C. Gómez-Guijarro +15
We present a study of the mid-IR (MIR) emission of quiescent galaxies (QGs) beyond the local universe. Using deep imaging in the SMACS-0723 cluster field we identify a mass…
MIDIS: Unveiling the Role of Strong Ha-emitters during the Epoch of Reionization with JWST
P. Rinaldi, K. I. Caputi, E. Iani +40
By using the ultra-deep \textit{JWST}/MIRI image at 5.6 in the Hubble eXtreme Deep Field, we constrain the role of strong H-emitters (HAEs) during Cosmic Reionization at $z…
MIDIS: JWST NIRCam and MIRI unveil the stellar population properties of Ly-emitters and Lyman-Break galaxies at z ~ 3-7
Edoardo Iani, Karina I. Caputi, Pierluigi Rinaldi +29
We study the stellar population properties of 182 spectroscopically-confirmed (MUSE/VLT) Lyman- emitters (LAEs) and 450 photometrically-selected Lyman-Break galaxies (LBGs) at z…
Spatially-resolved H and ionizing photon production efficiency in the lensed galaxy MACS1149-JD1 at a redshift of 9.11
J. Álvarez-Márquez, L. Colina, A. Crespo Gómez +32
We present MIRI/JWST medium-resolution spectroscopy (MRS) and imaging (MIRIM) of the lensed galaxy MACS1149-JD1 at a redshift of =9.10920.0002 (Universe age about 530 Myr).…
MIDIS: JWST/MIRI reveals the Stellar Structure of ALMA-selected Galaxies in the Hubble-UDF at Cosmic Noon
Leindert A. Boogaard, Steven Gillman, Jens Melinder +30
We present deep James Webb Space Telescope (JWST)/MIRI F560W observations of a flux-limited, ALMA-selected sample of 28 galaxies at z=0.5-3.6 in the Hubble Ultra Deep Field (HUDF).…
Little Red Dots or Brown Dwarfs? NIRSpec Discovery of Three Distant Brown Dwarfs Masquerading as NIRCam-Selected Highly-Reddened AGNs
Danial Langeroodi, Jens Hjorth
Cold, substellar objects such as brown dwarfs have long been recognized as contaminants in color-selected samples of active galactic nuclei (AGNs). In particular, their near- to mi…
First rest-frame infrared spectrum of a z>7 quasar: JWST/MRS observations of J1120+0641
Sarah E. I. Bosman, Javier Álvarez-Márquez, Luis Colina +29
We present a JWST/MRS spectrum of the quasar J1120+0641 at z=7.0848, the first spectroscopic observation of a reionisation-era quasar in the rest-frame infrared (m). In…
JWST detection of heavy neutron capture elements in a compact object merger
A. Levan, B. P. Gompertz, O. S. Salafia +80
The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray burs…
Type II-P Supernova Progenitor Star Initial Masses and SN 2020jfo: Direct Detection, Light Curve Properties, Nebular Spectroscopy, and Local Environment
Charles D. Kilpatrick, Luca Izzo, Rory O. Bentley +23
We present optical, ultraviolet, and infrared data of the type II supernova (SN II) 2020jfo at 14.5 Mpc. This wealth of multiwavelength data allows to compare different metrics com…
Ultraviolet Compactness of High-Redshift Galaxies as a Tracer of Early-Stage Gas Infall, Bursty Star Formation, and Offset from the Fundamental Metallicity Relation
Danial Langeroodi, Jens Hjorth
The empirical anti-correlation between gas-phase metallicity and star formation rate (SFR) at a fixed stellar mass, known as the fundamental metallicity relation (FMR), is commonly…
Uncovering the stellar structure of the dusty star-forming galaxy GN20 at z=4.055 with MIRI/JWST
L. Colina, A. Crespo Gómez, J. Álvarez-Márquez +35
Luminous infrared galaxies at high redshifts (>4) include extreme starbursts that build their stellar mass over short periods of time (>100 Myr). These galaxies are considered t…
