Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Christina Hedges, Alex Hughes, Steven Giacalone, George Zhou, Trevor J. David | Summary: We report the discovery of two planetary systems around comoving stars; TOI-2076 (TIC 27491137) and TOI-1807 (TIC 180695581). TOI-2076 is a nearby (41.9 pc) multi-planetary system orbiting a young (204$pm$50 Myr), bright (K […]

Kavli Affiliate: Eric Miller | First 5 Authors: Ruijie Jiang, Julia Gouvea, Eric Miller, David Hammer, Shuchin Aeron | Summary: This paper shows that a popular approach to the supervised embedding of documents for classification, namely, contrastive Word Mover’s Embedding, can be significantly enhanced by adding interpretability. This interpretability is achieved by incorporating a clustering […]

Kavli Affiliate: Erin Kara | First 5 Authors: Adam Ingram, Guglielmo Mastroserio, Michiel van der Klis, Edward Nathan, Riley Connors | Summary: We show that X-ray reverberation mapping can be used to measure the distance to type 1 active galactic nuclei (AGNs). This is because X-ray photons originally emitted from the `corona’ close to the […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Andrew Vanderburg, Joseph E. Rodriguez, , , | Summary: We place the first constraints on binary planets and exomoons from Doppler monitoring of directly imaged exoplanets. We model radial velocity observations of HR 8799 b, c, and d from Ruffio et al. (2021) and determine upper limits […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Siyi Xu, Hannah Diamond-Lowe, Ryan J. MacDonald, Andrew Vanderburg, Simon Blouin | Summary: WD 1856+534 b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD 1856+534. Here, we report an optical transmission spectrum of WD 1856+534 b obtained from ten transits using the Gemini […]

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Thomas J. Cooper, Gwen C. Rudie, Hsiao-Wen Chen, Sean D. Johnson, Fakhri S. Zahedy | Summary: We present a detailed study of two partial Lyman limit systems (pLLSs) of neutral hydrogen column density $N_mathrm{H,I}approx(1-3)times10^{16},mathrm{cm}^{-2}$ discovered at $z=0.5$ in the Cosmic Ultraviolet Baryon Survey (CUBS). Available far-ultraviolet […]

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Yitian Sun, Katelin Schutz, Anjali Nambrath, Calvin Leung, Kiyoshi Masui | Summary: Axions are a theoretically promising dark matter (DM) candidate. In the presence of radiation from bright astrophysical sources at radio frequencies, nonrelativistic DM axions can undergo stimulated decay to two nearly back-to-back photons, meaning that […]

Kavli Affiliate: Avi Shporer | First 5 Authors: Andrej Prsa, Angela Kochoska, Kyle E. Conroy, Nora Eisner, Daniel R. Hey | Summary: In this paper we present a catalog of 4584 eclipsing binaries observed during the first two years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binary candidates, detection of […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ling Zhu, Annalisa Pillepich, Glenn van de Ven, Ryan Leaman, Lars Hernquist | Summary: Galactic dynamical structures are fossil records of the assembly histories of galaxies. By analyzing the cosmological hydrodynamical simulation TNG50, we find that a dynamical structure that we call the "hot inner stellar halo," […]
