Kavli Affiliate: John Reynolds | Authors: Kandarp Dave, Donna B Stolz, Michael John Reynolds, Riyan Babidhan, Duncan X Dobbins, Tarun N. Bhatia, Hannah Yankello, Rohan Reddy, Younsoo Bae, Rehana K Leak, Sruti Shiva and Devika Soundara Manickam | Summary: Ischemic stroke causes brain endothelial cell (BEC) death and damages tight junction integrity of the blood-brain […]
Kavli Affiliate: Clarence L. Chang | First 5 Authors: Riccardo Gualtieri, Peter S. Barry, Thomas Cecil, Amy N. Bender, Clarence . L. Chang | Summary: Planar ortho-mode transducers (OMTs) are a commonly used method of coupling optical signals between waveguides and on-chip circuitry and detectors. While the ideal OMT-waveguide coupling requires minimal disturbance to the […]
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: David Gross | First 5 Authors: Laurens T. Ligthart, Mariami Gachechiladze, David Gross, , | Summary: A causal structure is a description of the functional dependencies between random variables. A distribution is compatible with a given causal structure if it can be realized by a process respecting these dependencies. Deciding whether a distribution […]
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: Alexander P. Ji | First 5 Authors: Rohan P. Naidu, Alexander P. Ji, Charlie Conroy, Ana Bonaca, Yuan-Sen Ting | Summary: The astrophysical origins of $r$-process elements remain elusive. Neutron star mergers (NSMs) and special classes of core-collapse supernovae (rCCSNe) are leading candidates. Due to these channels’ distinct characteristic timescales (rCCSNe: prompt, NSMs: […]
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: Lars Bildsten | First 5 Authors: William C. Schultz, Lars Bildsten, Yan-Fei Jiang, , | Summary: Increasing main sequence stellar luminosity with stellar mass leads to the eventual dominance of radiation pressure in stellar envelope hydrostatic balance. As the luminosity approaches the Eddington limit, additional instabilities (beyond conventional convection) can occur. These instabilities […]
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: Adam B. Mantz | First 5 Authors: Victoria Butler, Richard M. Feder, Tansu Daylan, Adam B. Mantz, Dale Mercado | Summary: We present a measurement of the relativistic corrections to the thermal Sunyaev-Zel’dovich (SZ) effect spectrum, the rSZ effect, toward the massive galaxy cluster RX J1347.5-1145 by combining sub-mm images from Herschel-SPIRE with […]
