k-Submodular Cover Problem with a Matroid Constraint
Xinru Li, Donglei Du, Qian Liu +2
We investigate k-submodular cover problem with a matroid constraint on an n-element ground set V , which seeks k disjoint subsets of V with minimal cost, where their union is an in…
Euclid. A two-point correlation approach to diagnosing star-related systematics in the Euclid spectroscopic survey
Euclid Collaboration, I. Risso, B. R. Granett +298
The Euclid spectroscopic survey will measure galaxy clustering with unprecedented precision, requiring stringent control of observational and instrumental systematics. Star-related…
Euclid: The convective-transition gap of 47 Tuc
M. Libralato, M. Griggio, R. Gerasimov +140
We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…
Euclid Quick Data Release (Q2) -- The Euclid Galactic Bulge Survey
J. -P. Beaulieu, E. Bachelet, M. Gilles +173
The Euclid Quick Data Release Q2 provides an unprecedented deep, wide-field, high-angular-resolution view of the inner Galactic bulge through the Euclid Galactic Bulge Survey (EGBS…
\textit{Euclid} preparation. Baryon acoustic oscillations extraction techniques: comparison and optimisation
Euclid Collaboration, E. Sarpa, A. Veropalumbo +296
We present the first end-to-end validation of the Euclid baryon acoustic oscillation (BAO) analysis pipeline, encompassing density-field reconstruction, two-point correlation funct…
Euclid preparation. Three-dimensional galaxy clustering in configuration space: Three-point correlation function estimation
Euclid Collaboration, A. Veropalumbo, M. Moresco +303
Higher-order correlation functions are firmly established as a fundamental tool for the statistical analysis of clustering in modern galaxy surveys. It was demonstrated that they g…
Euclid preparation. Galaxy power spectrum modelling in redshift space
Euclid Collaboration, B. Camacho Quevedo, M. Crocce +292
Accurate modelling of redshift-space distortions (RSD) is essential for maximizing the cosmological information extracted from large galaxy redshift surveys. In preparation for the…
Euclid preparation. Simulating thousands of Euclid spectroscopic skies
Euclid Collaboration, P. Monaco, G. Parimbelli +303
We present two extensive sets of 3500+1000 simulations of dark matter haloes on the past light cone, and two corresponding sets of simulated (`mock') galaxy catalogues that represe…
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…
Euclid preparation. 3-dimensional galaxy clustering in configuration space. Part I. 2-point correlation function estimation
Euclid Collaboration, S. de la Torre, F. Marulli +297
The 2-point correlation function of the galaxy spatial distribution is a major cosmological observable that enables constraints on the dynamics and geometry of the Universe. The Eu…
The ALPINE-ALMA [CII] Survey: Modelling ALMA and JWST lines to constrain the interstellar medium of galaxies
E. Veraldi, L. Vallini, F. Pozzi +13
In this work, we devise a model for estimating UV and optical line emission (i.e., CIII] A, H, [OIII] A, H, [NII] A) tracing HII regions in the interstellar…
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…
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…
Dynamically cold disks in the early Universe: myth or reality?
Mahsa Kohandel, Andrea Pallottini, Andrea Ferrara +3
Theoretical models struggle to reproduce dynamically cold disks with significant rotation-to-dispersion support() observed in star-forming galaxies in the early Uni…
