Kavli Affiliate: Scott A. Hughes | First 5 Authors: Lisa V. Drummond, Scott A. Hughes, , , | Summary: Very large mass ratio binary black hole systems are of interest both as a clean limit of the two-body problem in general relativity, as well as for their importance as sources of low-frequency gravitational waves. At […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Jiayin Dong, Chelsea X. Huang, George Zhou, Rebekah I. Dawson, Gudmundur K. Stefánsson | Summary: Close-in gas giants present a surprising range of stellar obliquity, the angle between a planet’s orbital axis and its host star’s spin axis. It is unclear whether the obliquities reflect the planets’ […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Steven Giacalone, Courtney D. Dressing, Christina Hedges, Veselin B. Kostov, Karen A. Collins | Summary: The James Webb Space Telescope (JWST) will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. We identify 18 potentially terrestrial planet candidates detected […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo, Eduardo J. S. Villaseñor, | Summary: We study a generalization of the Holst action where we admit nonmetricity and torsion in manifolds with timelike boundaries (both in the metric and tetrad formalism). We prove that its space of […]
Kavli Affiliate: Moritz Guenther | First 5 Authors: Taichi Uyama, Michihiro Takami, Gabriele Cugno, Vincent Deo, Olivier Guyon | Summary: We present multi-epoch observations of the RY~Tau jet for H$alpha$ and [ion{Fe}{2}] 1.644 micron~emission lines obtained with Subaru/SCExAO+VAMPIRES, Gemini/NIFS, and Keck/OSIRIS in 2019–2021. These data show a series of four knots within 1$arcsec$ consistent with […]

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: CHIME Collaboration, Mandana Amiri, Kevin Bandura, Anja Boskovic, Jean-François Cliche | Summary: We present a beam pattern measurement of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) made using the Sun as a calibration source. As CHIME is a pure drift scan instrument, we rely on the seasonal […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Mitali Damle, Martin Sparre, Philipp Richter, Maan H. Hani, Sebastián E. Nuza | Summary: Recent observations have revealed remarkable insights into the gas reservoir in the circumgalactic medium (CGM) of galaxy haloes. In this paper, we characterise the gas in the vicinity of Milky Way and Andromeda […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Lily L. Zhao, Debra A. Fischer, Eric B. Ford, Alex Wise, Michaël Cretignier | Summary: Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precision radial velocity (EPRV) exoplanet detection. Several methods […]
