Nonlinear velocity power spectrum: modeling the cosmological dependence on the Hubble constant and cold dark matter density

Francesca Lepori, Ruth Durrer, Martin Kunz +3

In this paper we present a semi-analytical model for the velocity power spectrum in $\La$CDM cosmology for wave numbers Mpc. We mainly concentrate on the dominant divergence…

Systematic study of fully heavy-flavored tetraquarks : Mass spectra, threshold analysis, and confrontation with LHC data

André Aimé Atangana Likéné, Alexis Franck Rothen, Dieudonné Nga Ongodo +2

Experimental searches for fully heavy tetraquark states are actively pursued at the LHC. The LHCb, CMS, and ATLAS collaborations have investigated fully charmed ,…

Was Schrödinger ever a determinist?

Flavio Del Santo, Nicolas Gisin

Erwin Schrödinger is often portrayed as a reactionary who resisted the indeterminism introduced by quantum mechanics, but on closer inspection his views on determinism prove to be…

XRISM Resolves the Circum-nuclear Environment of NGC 4945

Peter G. Boorman, Poshak Gandhi, Yoshihiro Ueda +31

Compton-thick Active Galactic Nuclei (AGN) represent one of the most elusive phases of massive black hole growth, yet are expected to contribute substantially to the Cosmic X-ray B…

The Fe I 4377 Ã Line as a Solar Faculae Indicator: Insights from Spectral Ratio Analysis

Katlyn L. Hobbs, Christopher A. Watson, Jean C. Costes +21

Faculae are a dominant source of stellar activity noise in radial velocity measurements, yet their low contrast and broad surface distribution make them difficult to track in disc-…
