Dark energy and negative compressibility of the Universe: A study based on cosmic equations of state
Felipe A. Asenjo, Ósmar Rodríguez, Ariel Órdenes Morales +1
All cosmological models are defined through energy and matter, which describe the evolution of the targeted Universe. Whether the content is simple or complex, it can be defined th…
Frozen-In Gravitational Fields
Felipe A. Asenjo, Maricarmen A. Winkler, Luca Comisso
Spacetime can undergo complex nonlinear evolution, as governed by the Einstein field equations, and a central challenge is to understand the geometric structures that arise, persis…
ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791
Georgina Dransfield, Antoine C. Petit, Amaury H. M. J. Triaud +45
Gas giant planets with periods orbiting Sun-like stars are a relatively uncommon outcome of planetary formation, and key questions about the nature and form…
The Dynamics of Human and AI-Generated Language: How Semantics Fluctuates across Different Timescales
Han-Jen Chang, Yasir Çatal, Angelika Wolman +5
Spoken language, whether produced by humans or large language models (LLM), unfolds over time with varying semantic content. However, we still lack simple, interpretable time-serie…
Detection of stratospheric HCN and tropospheric CO in Uranus and the implication for their sources
T. Cavalié, R. Moreno, C. Lefour +16
Uranus belongs to the category of ice giants that are common in our Galaxy. However, Uranus is one of the least explored and understood planets in our Solar System. This work aims…
POSEIDON II: The Anti-Aligned Orbit of the Warm Neptune TOI-1710 A b
Juan I. Espinoza-Retamal, Hareesh Bhaskar, Joshua N. Winn +7
We present an observation of the Rossiter-McLaughlin effect for the TOI-1710 system with the NEID spectrograph on the WIYN 3.5 m telescope. The system hosts a warm Neptune ($P\sim2…
