Kavli Affiliate: Salvatore Vitale | First 5 Authors: Jack Heinzel, Matthew Mould, Sofía Álvarez-López, Salvatore Vitale, | Summary: The origins of merging compact binaries observed by gravitational-wave detectors remains highly uncertain. Several astrophysical channels may contribute to the overall merger rate, with distinct formation processes imprinted on the structure and correlations in the underlying distributions […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Michael Boylan-Kolchin, Sandro Tacchella, Rohan P. Naidu | Summary: JWST has revealed a large population of ultra-violet (UV)-bright galaxies at $zgtrsim 10$ and possibly overly massive galaxies at $zgtrsim 7$, challenging standard galaxy formation models in the $Lambda$CDM cosmology. We use an empirical […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K Bhowmick, Laura Blecha, Paul Torrey, Rachel S Somerville, Luke Zoltan Kelley | Summary: JWST has recently revealed a large population of accreting black holes (BHs) in the early Universe. Even after accounting for possible systematic biases, the high-z $M_*-M_{rm rm bh}$ relation derived from these […]

Armstrong, Jorge Fernández Fernández, Simon Müller | Summary: We report the discovery of two transiting planets detected by the Transiting Exoplanet Survey Satellite (TESS), TOI-2374 b and TOI-3071 b, orbiting a K5V and an F8V star, respectively, with periods of […]

Kavli Affiliate: Lina Necib | First 5 Authors: Arpit Arora, Robyn E. Sanderson, Sukanya Chakrabarti, Andrew Wetzel, Thomas Donlon II | Summary: Measurements of the accelerations of stars enabled by time-series extreme-precision spectroscopic observations, from pulsar timing, and from eclipsing binary stars in the Solar Neighborhood offer insights into the mass distribution of the Milky […]
