Kavli Affiliate: Sara Seager | First 5 Authors: Mariona Badenas-Agusti, Andrew Vanderburg, Simon Blouin, Patrick Dufour, Javier Viaña | Summary: We present a catalogue of 62 polluted white dwarfs observed by the 9th Low-Resolution Data Release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST LRS DR9v1; R$approx$1,800) and the Early Data Release 3 […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Raven Gassis, Matthew B. Bayliss, Keren Sharon, Guillaume Mahler, Michael D. Gladders | Summary: Through observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from $Lambda$ Cold Dark Matter ($Lambda$CDM) cosmology. The shape and centroid deviations between the total matter […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Utkarsh Giri, Bridget C. Andersen, Pragya Chawla, Alice P. Curtin, Emmanuel Fonseca | Summary: The bright millisecond-duration radio burst from the Galactic magnetar SGR 1935+2154 in 2020 April was a landmark event, demonstrating that at least some fast radio burst (FRB) sources could be magnetars. The […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ciro Pinto, James F. Steiner, Arash Bodaghee, Priyanka Chakraborty, Malgosia Sobolewska | Summary: We investigate outflows and the physics of super-Eddington versus sub-Eddington regimes in black hole systems. Our focus is on prospective science using next-generation high-resolution soft X-ray instruments. We highlight the properties of black hole […]

Kavli Affiliate: Sara Seager | First 5 Authors: TRAPPIST-1 JWST Community Initiative, :, Julien de Wit, René Doyon, Benjamin V. Rackham | Summary: Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominent is the M8.5V star TRAPPIST-1 and its […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Natalí S. M. de Santi, Francisco Villaescusa-Navarro, L. Raul Abramo, Helen Shao, Lucia A. Perez | Summary: It has been recently shown that a powerful way to constrain cosmological parameters from galaxy redshift surveys is to train graph neural networks to perform field-level likelihood-free inference without imposing […]

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Mallory Harris, Diana Dragomir, Ismael Mireles, Karen A. Collins, Solène Ulmer-Moll | Summary: We report the discovery of two TESS sub-Neptunes orbiting the early M dwarf TOI-904 (TIC 261257684). Both exoplanets, TOI-904 b and c, were initially observed in TESS sector 12 with twin sizes of 2.49R$_oplus$ […]
