A survey of massive stars in the Small Magellanic Cloud, one of the Milky Way’s satellite galaxies, suggests that the small galaxy is being tidally stretched by another satellite, the Large Magellanic Cloud.
Researchers confirm that gadolinium contributes to a feature seen in the spectrum of AT2017gfo, helping to advance our understanding of nucleosynthesis in the aftermath of neutron star mergers.
Introducing nonzero initial orbital eccentricities into simulations brings the predictions of the eccentric Kozai–Lidov mechanism into alignment with observations.
The Antarctic Plateau is a great place for observing — even during the day; preliminary observations suggest that bright transients like nearby supernovae can be spotted from the site during the daytime.
Laboratory experiments show that the amino acid glycine preferentially associates with salt phases rather than water ice, suggesting that salt-rich ices could be targeted in a search for organic molecules.
The masses of 1,120 galaxy candidates at redshifts of 6.5 < z < 13.5 are consistent with existing cosmological models, though some of the most massive galaxies may require a high star-formation efficiency.
