Cosmological viability of a double field unified model from warm inflation
Rocco D'Agostino, Orlando Luongo
In this paper, we investigate the cosmological viability of a double scalar field model motivated by warm inflation. To this end, we first set up the theoretical framework in which…
Euclid: Covariance of weak lensing pseudo- estimates. Calculation, comparison to simulations, and dependence on survey geometry

Primordial Big Bang Nucleosynthesis and Generalized Uncertainty Principle
Giuseppe Gaetano Luciano
The Generalized Uncertainty Principle (GUP) naturally emerges in several quantum gravity models, predicting the existence of a minimal length at Planck scale. Here, we consider the…
Primordial gravitational waves from NANOGrav: a broken power-law approach
Micol Benetti, Leila Lobato Graef, Sunny Vagnozzi
We revisit the possibility that the stochastic common-spectrum process recently detected by the NANOGrav pulsar timing array experiment could be due to primordial gravitational wav…
Constraining non-minimally coupled -exponential inflation with CMB data
Felipe Bruno Medeiros dos Santos, Simony Santos da Costa, Raimundo Silva +2
The -exponential inflation is driven by a class of primordial potentials, derived in the framework of braneworld scenarios, that generalizes the well-known power law inflation.…

We present a tomographic weak lensing analysis of the Kilo Degree Survey Data Release 4 (KiDS-1000), using a new pseudo angular power spectrum estimator (pseudo-) under d…
Euclid preparation: XIX. Impact of magnification on photometric galaxy clustering
F. Lepori, I. Tutusaus, C. Viglione +183
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 s…
Search for subsolar-mass binaries in the first half of Advanced LIGO and Virgo's third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1634
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 and 1.0 in Advanced LIGO and Advanced Virgo dat…
Euclid: Constraining ensemble photometric redshift distributions with stacked spectroscopy
