Classification of blazars based on data-driven approaches
Simone Vaccaro, Maria Isabel Carnerero, Claudia M. Raiteri +5
Active galactic nuclei (AGNs), including blazars, exhibit distinctive variability in their optical light curves, making them ideal for classification studies. This work uses data f…
Observational Frontiers in the post-EoR 21-cm Intensity Mapping: Lessons from the SKA Pathfinders
Khandakar Md Asif Elahi, Somnath Bharadwaj, Philip Bull +21
The 21-cm line from neutral hydrogen has long been recognised as a promising tracer of the large-scale structure of the Universe. The line is weak however, making individual galaxy…
The quest for high-redshift radio galaxies. I. A pilot spectroscopic study
Alessandro Capetti, Barbara Balmaverde, Miguel Coloma Puga +4
The population of high-redshift radio galaxies (HzRGs) is still poorly studied because only a few of these objects are currently known. We here present the results of a pilot proje…
Euclid preparation. LIII. LensMC, weak lensing cosmic shear measurement with forward modelling and Markov Chain Monte Carlo sampling
Euclid Collaboration, G. Congedo, L. Miller +239
LensMC is a weak lensing shear measurement method developed for Euclid and Stage-IV surveys. It is based on forward modelling in order to deal with convolution by a point spread fu…
The radio properties of z>3.5 quasars: Are most high-redshift radio-loud active galactic nuclei obscured?
Alessandro Capetti, Barbara Balmaverde
We explore the radio properties of powerful (rest-frame luminosity W Hz at 500 MHz) high-redshift (z > 3.5) quasars. The aim of this study is to gain a bett…
Euclid preparation XLVI. The Near-IR Background Dipole Experiment with Euclid
Euclid Collaboration, A. Kashlinsky, R. G. Arendt +217
Verifying the fully kinematic nature of the cosmic microwave background (CMB) dipole is of fundamental importance in cosmology. In the standard cosmological model with the Friedman…
