With data from Pantheon, we have at our disposal a sample of more than a 1000 supernovae Ia covering a wide range of redshifts with good precision. Here, we make fits to the corresponding Hubble-Lemaître diagram with various cosmological models, with intergalactic extinction, evolution of the luminosity of supernovae, and redshift components due to

Lessons from the ionised and molecular mass of post-CE PNe
Close binary evolution is widely invoked to explain the formation of axisymmetric planetary nebulae, after a brief common envelope phase. The evolution of the primary would be interrupted abruptly, its still quite massive envelope being fully ejected to form the PN, which should be more massive than a planetary nebula coming from the same starSantander-García, Miguel et al.
Goobley/Lightweaver: Performance Focused Improvements
The v0.8 release of Lightweaver focuses significantly on performance enhancements in the backend, with some improved frontend flexibility regarding the printing of results. If you've been using a v0.8.0rc* version then you will already have most/all of these features. Notable features: Manual SIMD (x86_64) vectorisation throughout the opacityCmo et al.

The ultraviolet researcher to investigate the emergence of life: a mission proposal to ESA's F-call
The mission Ultraviolet Researcher to Investigate the Emergence of Life (URIEL) is designed to carry out low dispersion (600-1,000) UV spectropolarimetry in the 140-400 nm spectral range to investigate the formation of planetary systems, its interaction with stellar winds and search for signatures of prebiotic molecules by remote sensing of smallGómez de Castro, Ana I. et al.
Density, not radius, separates rocky and water-rich small planets orbiting M dwarf stars
Exoplanets smaller than Neptune are common around red dwarf stars (M dwarfs), with those that transit their host star constituting the bulk of known temperate worlds amenable for atmospheric characterization. We analyze the masses and radii of all known small transiting planets around M dwarfs, identifying three populations: rocky, water-rich, andLuque, Rafael et al.
