Quasars as Standard Candles V. Evaluation of a 0.06 dex intrinsic dispersion in the LX-LUV relation
Matilde Signorini, Guido Risaliti, Elisabeta Lusso +4
A characteristic feature of quasars is the observed non-linear relationship between their monochromatic luminosities at rest-frame 2500 Å and 2 keV. This relationship is evident ac…
A visual tool for assessing tension-resolving models in the - plane
Igor de O. C. Pedreira, Micol Benetti, Elisa G. M. Ferreira +2

Euclid preparation. LII. Forecast impact of super-sample covariance on 3x2pt analysis with Euclid
Euclid Collaboration, D. Sciotti, S. Gouyou Beauchamps +221
Deviations from Gaussianity in the distribution of the fields probed by large-scale structure surveys generate additional terms in the data covariance matrix, increasing the uncert…
Euclid: The search for primordial features
M. Ballardini, Y. Akrami, F. Finelli +126
Primordial features, in particular oscillatory signals, imprinted in the primordial power spectrum of density perturbations represent a clear window of opportunity for detecting ne…
AMICO galaxy clusters in KiDS-DR3: constraints on CDM from extreme value statistics
Valerio Busillo, Giovanni Covone, Mauro Sereno +11
We constrain the CDM cosmological parameter by applying the extreme value statistics for galaxy cluster mass on the AMICO KiDS-DR3 catalog. We sample the posterior distr…
Tensions with the flat CDM model from high-redshift cosmography
G. Bargiacchi, M. G. Dainotti, S. Capozziello
The longstanding search for the cosmological model that best describes the Universe has been made more intriguing since the recent discovery of the Hubble constant, , tensio…
Cosmographic view on the and tensions
Rocco D'Agostino, Rafael C. Nunes
Measurements of the and parameters within the standard cosmological model recently highlighted significant statistical tensions between the cosmic microwave background…
Quasars as Standard Candles IV. Analysis of the X-ray and UV indicators of the disc-corona relation
Matilde Signorini, Guido Risaliti, Elisabeta Lusso +4
Context: A non-linear relation between quasar monochromatic luminosities at 2500A and 2 keV holds at all observed redshifts and luminosities, and it has been used to derive quasar…
Euclid: Constraints on f(R) cosmologies from the spectroscopic and photometric primary probes
S. Casas, V. F. Cardone, D. Sapone +126

Euclid: Constraining linearly scale-independent modifications of gravity with the spectroscopic and photometric primary probes
N. Frusciante, F. Pace, V. F. Cardone +127
The future Euclid space satellite mission will offer an invaluable opportunity to constrain modifications to Einstein's general relativity at cosmic scales. We focus on modified gr…
Quasars: standard candles up to z=7.5 with the precision of Supernovae Ia
Maria Giovanna Dainotti, Giada Bargiacchi, Aleksander Łukasz Lenart +2
Currently, the Cold Dark Matter model, which relies on the existence of cold dark matter and a cosmological constant , best describes the Universe. However, we lack informat…
Reducing the uncertainty on the Hubble constant up to 35\% with an improved statistical analysis: different best-fit likelihoods for Supernovae Ia, Baryon Acoustic Oscillations, Quasars, and Gamma-Ray Bursts
Maria Giovanna Dainotti, Giada Bargiacchi, Małgorzata Bogdan +5
Cosmological models and their parameters are widely debated, especially about whether the current discrepancy between the values of the Hubble constant, , obtained by type I…
