Euclid preparation : XIX. Impact of magnification on photometric galaxy clustering
(EDP Sciences, 2022)
Aims. We investigate the importance of lensing magnification for estimates of galaxy clustering and its cross-correlation with shear for the photometric sample of Euclid. Using updated specifications, we study the impact ...
Euclid preparation : XV. Forecasting cosmological constraints for the Euclid and CMB joint analysis
(EDP Sciences, 2022)
The combination and cross-correlation of the upcoming Euclid data with cosmic microwave background (CMB) measurements is a source of great expectation since it will provide the largest lever arm of epochs, ranging from ...
Euclid preparation : XVII. Cosmic Dawn Survey : Spitzer Space Telescope observations of the Euclid deep fields and calibration fields
(EDP Sciences, 2022)
We present a new infrared survey covering the three Euclid deep fields and four other Euclid calibration fields using Spitzer Space Telescope’s Infrared Array Camera (IRAC). We combined these new observations with all ...
Euclid preparation : XVIII. The NISP photometric system
(EDP Sciences, 2022)
Euclid will be the first space mission to survey most of the extragalactic sky in the 0.95–2.02 µm range, to a 5 σ point-source median depth of 24.4 AB mag. This unique photometric dataset will find wide use beyond Euclid’s ...
Euclid preparation : XX. The Complete Calibration of the Color–Redshift Relation survey : LBT observations and data release
(EDP Sciences, 2022)
The Complete Calibration of the Color–Redshift Relation survey (C3R2) is a spectroscopic program designed to empirically calibrate the galaxy color–redshift relation to the Euclid depth (IE = 24.5), a key ingredient for ...
Euclid preparation : XXII. Selection of quiescent galaxies from mock photometry using machine learning
(EDP Sciences, 2023)
The Euclid Space Telescope will provide deep imaging at optical and near-infrared wavelengths, along with slitless near-infrared spectroscopy, across ~15 000deg2 of the sky. Euclid is expected to detect ~12 billion ...
Euclidean spaces as weak tangents of infinitesimally Hilbertian metric measure spaces with Ricci curvature bounded below
(Walterde Gruyter GmbH & Co. KG, 2015)
We show that in any infinitesimally Hilbertian CD
.K; N /-space at almost
every point there exists a Euclidean weak tangent, i.e., there exists a sequence of dilations
of the space that converges to a Euclidean space ...
European catfish (Silurus glanis) as a freshwater apex predator drives ecosystem via its diet adaptability
(Nature Publishing Group, 2017)
Apex predators play a key role in ecosystem stability across environments but their numbers in general
are decreasing. By contrast, European catfsh (Silurus glanis), the European freshwater apex predator,
is on the ...
Eutrophication and browning influence Daphnia nutritional ecology
(Taylor & Francis, 2019)
Climate change and land-use practices can enhance lake eutrophication and browning, which influence phytoplankton composition by decreasing the availability of food high in nutritional quality (algae) and increasing the ...
