The R-Process Alliance: Hunting for gold in the near-UV spectrum of 2MASS J05383296-5904280
Kavli Affiliate: Anna Frebel | First 5 Authors: Terese T. Hansen, Ian U. Roederer, Shivani P. Shah, Rana Ezzeddine, Timothy C. Beers | Summary: Context. Over the past few years, the $R$-Process Alliance (RPA) has successfully carried out a search for stars that are highly enhanced in elements produced via the rapid neutron-capture ($r$-) process. […]

The Power of the Cosmic Web
Kavli Affiliate: Jia Liu | First 5 Authors: James Sunseri, Adrian E. Bayer, Jia Liu, , | Summary: We study the cosmological information contained in the cosmic web, categorized as four structure types: nodes, filaments, walls, and voids, using the Quijote simulations and a modified nexus+ algorithm. We show that splitting the density field by […]

BlackTHUNDER strikes twice: rest-frame Balmer-line absorption and high Eddington accretion rate in a Little Red Dot at $z=7.04$
Kavli Affiliate: Debora Sijacki | First 5 Authors: Francesco D’Eugenio, Roberto Maiolino, Michele Perna, Hannah Uebler, Xihan Ji | Summary: JWST spectroscopy has revealed a population of compact objects at redshifts $z=2$-9 with `v’-shaped spectral energy distributions, broad permitted lines, and, often, hydrogen Balmer absorption. Among these `Little Red Dots’ (LRDs), Abell2744-QSO1 at $z=7.04$ has […]
