Kavli Affiliate: Sara Seager | First 5 Authors: Kielan K. W. Hoch, Christopher A. Theissen, Travis S. Barman, Marshall D. Perrin, Jean-Baptiste Ruffio | Summary: We present the atmospheric characterization of the substellar companion HD 19467 B as part of the pioneering JWST GTO program to obtain moderate resolution spectra (R$sim$2,700, 3-5$mu$m) of a high-contrast […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Avrajit Bandyopadhyay, Rana Ezzeddine, Carlos Allende Prieto, Nima Aria, Shivani P. Shah | Summary: Understanding the abundance pattern of metal-poor stars and the production of heavy elements through various nucleosynthesis processes offers crucial insights into the chemical evolution of the Milky Way, revealing primary sites and major […]

Kavli Affiliate: Lina Necib | First 5 Authors: Dylan Folsom, Mariangela Lisanti, Lina Necib, Danny Horta, Mark Vogelsberger | Summary: Observations of the Milky Way’s stellar halo find that it is predominantly comprised of a radially-biased population of stars, dubbed the Gaia Sausage–Enceladus, or GSE. These stars are thought to be debris from dwarf galaxy […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hoang Nhan Luu, Philip Mocz, Mark Vogelsberger, Alvaro Pozo, Tom Broadhurst | Summary: Fuzzy dark matter (FDM) is a compelling candidate for dark matter, offering a natural explanation for the structure of diffuse low-mass haloes. However, the canonical FDM model with a mass of $10^{-22}~{rm eV}$ encounters […]

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Mandana Amiri, Arnab Chakraborty, Simon Foreman, Mark Halpern, Alex S Hill | Summary: We present the first results of the holographic beam mapping program for the Canadian Hydrogen Intensity Mapping Experiment (CHIME). We describe the implementation of the holographic technique as adapted for CHIME, and introduce […]

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Fei Dai, Andrew W. Howard, Samuel Halverson, Jaume Orell-Miquel, Enric Palle | Summary: TOI-6255~b (GJ 4256) is an Earth-sized planet (1.079$pm0.065$ $R_oplus$) with an orbital period of only 5.7 hours. With the newly commissioned Keck Planet Finder (KPF) and CARMENES spectrographs, we determined the planet’s mass to […]
