Computational access to lattice and long-wavelength physics in quantum mutual information
Quantum mutual information is an important tool for characterizing correlations in quantum many-body systems, but its numerical evaluation is often prohibitively expensive. While some variants of Rényi Mutual Information (RMI) are computationally more tractable, it is not clear whether they correctly capture the long-wavelength physics or are dominated by UV effects, which is of key importance in lattice simulations. We analyze the relevance of lattice effects on the family of $α$-$z$ Rényi …

ZTF SNe Ia DR2: Towards cosmology-grade ZTF supernova light curves using scene modeling photometry
The Zwicky Transient Facility (ZTF) is conducting a wide-field survey of the northern sky in three optical bands and the collaboration cosmology working group has released 3628 spectroscopically confirmed Type Ia supernovae (SNe Ia) discovered during its first 2.5 years of operation. This "ZTF SN Ia DR2" sample is the largest SN Ia dataset to date. Fully exploiting this dataset to improve understanding of the properties of dark energy requires a photometric accuracy of O(0.1%). This can be ac…

Electron impact ro-vibrational transitions and dissociative recombination of H2+ and HD+: Rate coefficients and astrophysical implications
Context. Molecular hydrogen and its cation H+2 are among the first species formed in the early Universe, and play a key role in the thermal and chemical evolution of the primordial gas. In molecular clouds, H+2 ions formed through ionization of H2 by particles react rapidly with H2 to form H+3 , triggering the formation of almost all detected interstellar molecules. Aims. We present a new set of cross sections and rate coefficients for state-to-state ro-vibrational transitions of the H+2 and HD…

Earth as a potential source of life For Europa's subsurface ocean
The paper discusses the possibility of dust particles containing living bacteria ejected from Earth, reaching Europa and landing on its surface. It is shown that, taking certain factors into account, over a period of (30-80) Myr (the estimated age of Europa's ocean), Jupiter's moon would have been impacted by approximately $3\times 10^{23}$ to $8\times 10^{23}$ particles in total, within which a bacterium could have survived. In this paper we discuss the possibility of dust grains entering liqu…
