The carbon isotope ratio of β Pic b with high-resolution spectroscopy
D. González Picos, I. A. G. Snellen, R. Landman +6
Isotopic ratios trace the formation and evolution of planets and link their atmospheres to the chemistry of their natal protoplanetary discs. We measure $^{12}\mathrm{C}/^{13}\math…

The resummation model in FLAMINGO: precisely predicting matter power suppression from observed halo baryon fractions
Marcel P. van Daalen, Ioannis Koutalios, Jeger C. Broxterman +4
In order to derive unbiased cosmological parameters from Stage-IV surveys, we need models that can predict the matter power spectrum for at least $k\,\lesssim\,10\,h\mathrm{\,Mpc^{…

Predicting Binary Neutron Star Postmerger Spectra Using Artificial Neural Networks
Dimitrios Pesios, Ioannis Koutalios, Dimitris Kugiumtzis +1
Gravitational waves in the postmerger phase of binary neutron star mergers may become detectable with planned upgrades of existing gravitational-wave detectors or with more sensiti…
