Euclid Preparation. XXXVII. Galaxy colour selections with Euclid and ground photometry for cluster weak-lensing analyses
Euclid Collaboration, G. F. Lesci, M. Sereno +238
We derived galaxy colour selections from Euclid and ground-based photometry, aiming to accurately define background galaxy samples in cluster weak-lensing analyses. Given any set o…
Euclid preparation. Spectroscopy of active galactic nuclei with NISP
Euclid Collaboration, E. Lusso, S. Fotopoulou +246
The statistical distribution and evolution of key properties (e.g. accretion rate, mass, or spin) of active galactic nuclei (AGN), remain an open debate in astrophysics. The ESA Eu…
Euclid preparation. XXXI. The effect of the variations in photometric passbands on photometric-redshift accuracy
Euclid Collaboration, Stéphane Paltani, J. Coupon +214
The technique of photometric redshifts has become essential for the exploitation of multi-band extragalactic surveys. While the requirements on photo-zs for the study of galaxy evo…
Decoding the IRX-β dust attenuation relation in star-forming galaxies at intermediate redshift
M. Hamed, F. Pistis, M. Figueira +11
We aim to understand what drives the IRX-βdust attenuation relation at intermediate redshift (0.5 < z < 0.8) in star-forming galaxies. We investigate the role of various galaxy pro…
Stellar metallicity from optical and UV spectral indices: Test case for WEAVE-StePS
F. R. Ditrani, M. Longhetti, F. La Barbera +35
The upcoming generation of optical spectrographs on four meter-class telescopes, with their huge multiplexing capabilities, excellent spectral resolution, and unprecedented wavelen…
LBT-MODS spectroscopy of high-redshift candidates in the Chandra J1030 field. A newly discovered z2.8 large scale structure
Stefano Marchesi, Marco Mignoli, Roberto Gilli +13
We present the results of a spectroscopic campaign with the Multi-Object Double Spectrograph (MODS) instrument mounted on the Large Binocular Telescope (LBT), aimed at obtaining a…
WEAVE-StePS. A stellar population survey using WEAVE at WHT
A. Iovino, B. M. Poggianti, A. Mercurio +44
The upcoming new generation of optical spectrographs on four-meter-class telescopes will provide valuable opportunities for forthcoming galaxy surveys through their huge multiplexi…
Euclid preparation. XXX. Performance assessment of the NISP Red-Grism through spectroscopic simulations for the Wide and Deep surveys
Euclid Collaboration, L. Gabarra, C. Mancini +232
This work focuses on the pilot run of a simulation campaign aimed at investigating the spectroscopic capabilities of the Euclid Near-Infrared Spectrometer and Photometer (NISP), in…
