Can photoevaporation open gaps in protoplanetary discs?

Michael L. Weber, Barbara Ercolano, Giovanni Picogna

We investigate whether photoevaporation alone can open and sustain gaps in protoplanetary discs by coupling the evolving disc structure with the photoevaporative flow in two dimens…

The Local Distance Network: a community consensus report on the measurement of the Hubble constant at 1% precision

H0DN Collaboration, Stefano Casertano, Gagandeep Anand +35

The direct, empirical determination of the local value of the Hubble constant (H0) has markedly advanced thanks to improved instrumentation, measurement techniques, and distance es…

Euclid Collaboration, A. Pezzotta, C. Moretti +246

We investigate the accuracy of the perturbative galaxy bias expansion in view of the forthcoming analysis of the Euclid spectroscopic galaxy samples. We compare the performance of…

Euclid preparation LXIII. Simulations and nonlinearities beyond CDM. 2. Results from non-standard simulations

Euclid Collaboration, G. Rácz, M. -A. Breton +275

The Euclid mission will measure cosmological parameters with unprecedented precision. To distinguish between cosmological models, it is essential to generate realistic mock observa…

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…
