Euclid Quick Data Release (Q1). Refining the strong lens sample with Space Warps crowd-sourced science
Euclid Collaboration, P. Holloway, A. Verma +315
We demonstrate the efficacy of crowd-sourced refinement of strong gravitational lens candidate samples by citizen scientists. Binary (lens/non-lens) classification by citizen scien…
Euclid: Forecasting the number counts of bright line emitters in the Euclid Wide Survey and Euclid Deep fields
Euclid Collaboration, P. Cassata, S. Quai +308
The Euclid mission will revolutionize our understanding of the visible Universe by collecting images and spectra of millions of galaxies across cosmic time and environments. Here,…
Euclid. Predicting scaling relations for emission-line galaxies using simulated data
Euclid Collaboration, C. Mancini, L. Gabarra +317
The Euclid spectroscopic surveys will substantially increase the number of observed emission-line galaxies. We assess the ability of the Euclid Wide Survey (EWS) and Euclid Deep Su…
Euclid Quick Data Release (Q1). Mass-to-light ratio of elliptical galaxies: constraints from strong lensing
Euclid Collaboration, A. Sonnenfeld, A. Nersesian +312
Mass is among the most fundamental properties describing a galaxy. The relation between the luminosity and the total mass of a galaxy contains information on the efficiency of the…
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…
Precise QCD Predictions for the Scotogenic Model at Colliders
Mohammed Boukidi, Camila Ramos, Richard Ruiz
Motivated by the anticipated data rates of the high-luminosity phase of the Large Hadron Collider, we report the first predictions up to next-to-leading order in quantum chromodyna…
Euclid: Quick Data Release (Q1) -- Optical hotspots in powerful radio galaxies
M. J. Hardcastle, L. Bisigello, M. Bondi +154
The hotspots of powerful radio galaxies are the sites of high-energy particle acceleration, but radio observations give us limited information on the electron energy distributions…
Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting
Euclid Collaboration, J. Calhau, G. Calderone +312
A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep…
Euclid: Data Release 1 (DR1) -- Fornax-7, an ultra-faint companion to the Fornax dwarf spheroidal galaxy? A remote star cluster or dwarf satellite of the Fornax dSph
T. Saifollahi, A. Lançon, A. M. N. Ferguson +165
We report the discovery of an ultra-faint stellar system in the vicinity of the Fornax dwarf spheroidal (dSph) galaxy in Euclid DR1. This system, which we designate Fornax-7, is lo…
Euclid: Quick Data Release (Q1) -- Exploring the detailed visual morphology of galaxies in clusters
P. Mas-Buitrago, S. Kruk, D. O'Ryan +167
Galaxy clusters provide unique laboratories for studying environmental effects on galaxy evolution. The morphology--density (--) and morphology--cluster-centric radius (--…
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 preparation. The shape of halo profiles in CDM and non-standard cosmologies
Euclid Collaboration, L. Pizzuti, G. Y. Ferron +304
We study the shape of three-dimensional and projected dark-matter halo profiles extracted from cosmological -body simulations in CDM and non-standard cosmologies, using the \…
The PAU Survey: Photometric Calibration of Narrow Band Images
F. J. Castander, S. Serrano, M. Eriksen +20
The Physics of the Accelerating Universe (PAU) camera is an optical narrow band and broad band imaging instrument mounted at the prime focus of the William Herschel Telescope. We d…
