Euclid: High-precision imaging astrometry and photometry from Early Release Observations. I. Internal kinematics of NGC 6397 by combining Euclid and Gaia data
M. Libralato, L. R. Bedin, M. Griggio +175
The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of 0.57 deg. This e…
Euclid: The - relation as a function of redshift. I. The black hole in NGC 1272
R. Saglia, K. Mehrgan, S. de Nicola +148
Core ellipticals, massive early-type galaxies have an almost constant inner surface brightness profile. The size of the core region correlates with the mass of the finally merged b…
Euclid preparation. Exploring the properties of proto-clusters in the Simulated Euclid Wide Survey
Euclid Collaboration, H. Böhringer, G. Chon +263
Galaxy proto-clusters are receiving an increased interest since most of the processes shaping the structure of clusters of galaxies and their galaxy population are happening at ear…
Euclid and KiDS-1000: Quantifying the impact of source-lens clustering on cosmic shear analyses
L. Linke, S. Unruh, A. Wittje +150
The transition from current Stage-III surveys such as the Kilo-Degree Survey (KiDS) to the increased area and redshift range of Stage IV surveys such as Euclid will significantly i…
Euclid preparation. LI. Forecasting the recovery of galaxy physical properties and their relations with template-fitting and machine-learning methods
Euclid Collaboration, A. Enia, M. Bolzonella +260
Euclid will collect an enormous amount of data during the mission's lifetime, observing billions of galaxies in the extragalactic sky. Along with traditional template-fitting metho…
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…
Euclid: Early Release Observations -- Dwarf galaxies in the Perseus galaxy cluster
F. R. Marleau, J. -C. Cuillandre, M. Cantiello +193
We make use of the unprecedented depth, spatial resolution, and field of view of the Euclid Early Release Observations of the Perseus galaxy cluster to detect and characterise the…
Euclid: Early Release Observations -- Overview of the Perseus cluster and analysis of its luminosity and stellar mass functions
J. -C. Cuillandre, M. Bolzonella, A. Boselli +199
The Euclid ERO programme targeted the Perseus cluster of galaxies, gathering deep data in the central region of the cluster over 0.7 square degree, corresponding to approximately 0…
Euclid: Early Release Observations -- Globular clusters in the Fornax galaxy cluster, from dwarf galaxies to the intracluster field
T. Saifollahi, K. Voggel, A. Lançon +196
We present an analysis of Euclid observations of a 0.5 deg field in the central region of the Fornax galaxy cluster that were acquired during the performance verification phase…
Euclid: Early Release Observations -- Deep anatomy of nearby galaxies
L. K. Hunt, F. Annibali, J. -C. Cuillandre +196
Euclid is poised to make significant advances in the study of nearby galaxies in the local Universe. Here we present a first look at 6 galaxies observed for the Nearby Galaxy Showc…
Euclid: Early Release Observations -- Unveiling the morphology of two Milky Way globular clusters out to their periphery
D. Massari, E. Dalessandro, D. Erkal +158
As part of the Euclid Early Release Observations (ERO) programme, we analyse deep, wide-field imaging from the VIS and NISP instruments of two Milky Way globular clusters (GCs), na…
Euclid: Early Release Observations -- A glance at free-floating new-born planets in the sigma Orionis cluster
E. L. Martín, M. {Ž}erjal, H. Bouy +175
We provide an early assessment of the imaging capabilities of the Euclid space mission to probe deeply into nearby star-forming regions and associated very young open clusters, and…
