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…
Satellite compaction pathways: environmental drivers shaping dwarf galaxy corpulence in the TNG50 simulation
Abhner P. De Almeida, Gary A. Mamon, Gastão B. Lima Neto
We explore the physical mechanisms driving dwarf galaxy corpulence, focusing on those that end up as compact satellites. We select dwarf galaxies at with $\log(M_\star/{\rm M…
Ram-pressure-induced star formation in low-mass galaxies infalling on-to the Coma cluster: insights from DESI
Kirill A. Grishin, Igor V. Chilingarian, Gary A. Mamon +2
Ram-pressure stripping is a key driver of galaxy morphological transformation in clusters, contributing to the formation of quenched, especially dwarf, populations. Ram-pressure co…
Star formation quenching precedes morphological transformation in COSMOS-WEB's richest galaxy groups
Z. Ghaffari, G. Gozaliasl, A. Biviano +26
We analyzed the 25 richest galaxy groups in COSMOS-Web at z = 0.18-3.65, identified via the AMICO algorithm. These groups contain 20-30 galaxies with high (>75%) membership probabi…
Euclid Quick Data Release (Q1). Quenching precedes bulge formation in dense environments but follows it in the field
Euclid Collaboration, F. Gentile, E. Daddi +321
(Abridged) The bimodality between star-forming discs and quiescent spheroids requires the existence of two main processes: the galaxy quenching and the morphological transformation…
Euclid preparation. XCI. Validation method for the detections in the Euclid Catalogue of Galaxy Clusters using external data
Euclid Collaboration, J. -B. Melin, S. A. Stanford +315
We present our methodology for identifying known clusters as counterparts to objects in the Euclid Catalogue of Galaxy Clusters (ECGC). Euclid is expected to detect a large number…
AXES-SDSS: Solving the puzzle of X-ray emission of optical galaxy groups via a modified Hausdorff distance
J. Kosowski, A. Finoguenov, E. Tempel +1
The identification of X-ray and CMB sources as galaxy groups and clusters is a prerequisite for cluster cosmology. But the identification of groups, especially nearby ones, suffers…
Modelling the selection of galaxy groups with end to end simulations
R. Seppi, D. Eckert, A. Finoguenov +13
Feedback from supernovae and AGN shapes galaxy formation and evolution, yet its impact remains unclear. Galaxy groups offer a crucial probe, as their binding energy is comparable t…
Tracing Galaxy Evolution in infalling galaxies of Abell 496: From Starburst to Quenching
M. M. López-Gutiérrez, H. Bravo-Alfaro, P. T. Rahna +4
During the fall of late-type galaxies into clusters, they can experiment a variety of evolutionary mechanisms according their local environment. Consequently, studying the UV emiss…
A Census of Compact Elliptical Galaxies in the Coma Cluster
Aleksandra V. Sharonova, Kirill A. Grishin, Igor V. Chilingarian +3
Compact elliptical (cE) galaxies are compact stellar systems with stellar masses of and radii typically < 0.6 kpc. Here we investigate the prop…
Euclid Quick Data Release (Q1). First detections from the galaxy cluster workflow
Euclid Collaboration, S. Bhargava, C. Benoist +351
The first survey data release by the Euclid mission covers approximately in the Euclid Deep Fields to the same depth as the Euclid Wide Survey. This paper show…
Dark matter fraction derived from the M31 rotation curve
F. Hammer, Y. B. Yang, P. Amram +6
Mass estimates of a spiral galaxy derived from its rotation curve must account for the galaxy's past accretion history. There are several lines of evidence indicating that M31 expe…
The Milky Way accretion history compared to cosmological simulations -- from bulge to dwarf galaxy infall
F. Hammer, Y. J. Jiao, G. A. Mamon +6
Galactic halos are known to grow hierarchically, inside out. This implies a correlation between the infall lookback time of satellites and their binding energy. Cosmological simula…
Euclid preparation: TBD. The impact of line-of-sight projections on the covariance between galaxy cluster multi-wavelength observable properties -- insights from hydrodynamic simulations
Euclid Collaboration, A. Ragagnin, A. Saro +240
Cluster cosmology can benefit from combining multi-wavelength studies, which can benefit from characterising the correlation coefficients between different mass-observable relation…
High Precision Astrometry Science in the Context of Space Mission Prospectives
Fabien Malbet, Gary A. Mamon, Lucas Labadie +5
Astrometry is one of the oldest branches of astronomy which measures the position, the proper motion and parallax of celestial objects. Following the Hipparcos and Gaia missions th…
Euclid: Early Release Observations -- A preview of the Euclid era through a galaxy cluster magnifying lens
H. Atek, R. Gavazzi, J. R. Weaver +200
We present the first analysis of the Euclid Early Release Observations (ERO) program that targets fields around two lensing clusters, Abell 2390 and Abell 2764. We use VIS and NISP…
