Euclid: Early Release Observations -- The extended stellar component of the IC10 dwarf galaxy

F. Annibali, A. M. N. Ferguson, P. M. Sanchez-Alarcon +175

We present a detailed analysis of the old, extended stellar component of the Local Group dwarf galaxy IC 10 using deep resolved-star photometry in the VIS and NISP bands of the Euc…

Impact of Fading Correlation on the High-SNR Regime of Reconfigurable Intelligent Surfaces

Paula Isabel Tilleria Lucero, Bryan Fernando Sarango Rodríguez, Fernando Darío Almeida García +1

This paper addresses three critical limitations in previous analyses of RIS-aided wireless systems: propagation environments with fixed diversity gain, restricted spatial correlati…

Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581

João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145

Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…

Euclid: Early Release Observations of diffuse stellar structures and globular clusters as probes of the mass assembly of galaxies in the Dorado group

M. Urbano, P. -A. Duc, T. Saifollahi +160

Deep surveys reveal tidal debris and associated compact stellar systems. Euclid's unique combination of capabilities (spatial resolution, depth, and wide sky coverage) will make it…

Dynamical mass of the Serpens intermediate-mass young stellar system EC\,95 with DYNAMO--VLBA

Jazmín Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +8

We present dynamical mass measurements, obtained from multi-epoch Very Long Baseline Interferometry (VLBI) observations, for the young multiple stellar system EC\,95, located in th…

Euclid preparation LXX. Forecasting detection limits for intracluster light in the Euclid Wide Survey

Euclid Collaboration, C. Bellhouse, J. B. Golden-Marx +292

The intracluster light (ICL) permeating galaxy clusters is a tracer of the cluster's assembly history, and potentially a tracer of their dark matter structure. In this work we expl…
