Extended [CII] gas emission in and around a massive quiescent galaxy at z=7.3
F. Valentino, A. Pensabene, A. Weibel +16
We report the discovery of [CII] 158 micron emission in and around the most distant known massive quiescent galaxy RUBIES-UDS-QG-z7 at z = 7.27. Observed with ALMA in band 6, the […
RIOJA. The dusty outflows and density-complex interstellar medium in the N-enhanced lensed galaxy RXCJ2248-ID at z=6.1
A. Crespo Gómez, Y. Tamura, L. Colina +19
We present an analysis on the kinematics and physical properties of the ionized gas in the lensed galaxy RXCJ2248-ID at z=6.1 based on high-resolution JWST NIRSpec/IFU data in comb…
DeepDive: A deep dive into the physics of the first massive quiescent galaxies in the Universe
K. Ito, F. Valentino, G. Brammer +26
We present the DeepDive program, in which we obtained deep JWST/NIRSpec G235M/F170LP spectra for ten primary massive () quiescent galaxies at $z\…
ALMA Band 3 Selection of Ultra-high Redshift Dropouts: The final challenge to ΛCDM
C. Lovell, M. Lee, A. Vijayan +10
The Lyman-break technique has been used to successfully identify high-redshift candidates in broad-band photometric data in the rest-frame optical and NIR using the dropout techniq…
A merging pair of massive quiescent galaxies at in the Cosmic Vine
K. Ito, F. Valentino, M. Farcy +26
We report the spectroscopic confirmation of a merging pair of massive quiescent galaxies at . Using JWST observations, we confirm that the two galaxies lie at a projected s…
Gas outflows in two recently quenched galaxies at z = 4 and 7
F. Valentino, K. E. Heintz, G. Brammer +33
Outflows are a key element in the baryon cycle of galaxies, and their properties provide a fundamental test for our models of how star formation quenches in galaxies. Here we repor…
Tracing the evolutionary pathways of dust and cold gas in high-z quiescent galaxies with SIMBA
G. Lorenzon, D. Donevski, K. Lisiecki +13
Recent discoveries of copious amounts of dust in quiescent galaxies (QGs) at high redshifts () challenge the conventional view that these objects have poor interstell…
The JWST-PRIMAL Legacy Survey. A JWST/NIRSpec reference sample for the physical properties and Lyman- absorption and emission of galaxies at
K. E. Heintz, G. B. Brammer, D. Watson +45
One of the surprising early findings with JWST has been the discovery of a strong "roll-over" or a softening of the absorption edge of Ly in a large number of galaxies at ($z\gt…
Outshining in the Spatially Resolved Analysis of a Strongly-Lensed Galaxy at z=6.072 with JWST NIRCam
C. Giménez-Arteaga, S. Fujimoto, F. Valentino +19
We present JWST/NIRCam observations of a strongly-lensed, multiply-imaged galaxy at , with magnification factors >~20 across the galaxy. We perform a spatially-resolved an…
The cold interstellar medium of a normal sub- galaxy at the end of reionization
F. Valentino, S. Fujimoto, C. Giménez-Arteaga +21
We present the results of a ~60-hr observational campaign with ALMA targeting a spectroscopically confirmed and lensed sub- galaxy at z=6.07, identified during the ALMA Le…
Primordial Rotating Disk Composed of 15 Dense Star-Forming Clumps at Cosmic Dawn
S. Fujimoto, M. Ouchi, K. Kohno +43
Early galaxy formation, initiated by the dark matter and gas assembly, evolves through frequent mergers and feedback processes into dynamically hot, chaotic structures. In contrast…
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…
