Kavli Affiliate: Herman L. Marshall | First 5 Authors: Herman L. Marshall, Yang Chen, Jeremy J. Drake, Matteo Guainazzi, Vinay L. Kashyap | Summary: We describe a process for cross-calibrating the effective areas of X-ray telescopes that observe common targets. The targets are not assumed to be "standard candles" in the classic sense, in that […]
Kavli Affiliate: Edward H. Morgan | First 5 Authors: Samuel H. C. Cabot, Aaron Bello-Arufe, João M. Mendonça, René Tronsgaard, Ian Wong | Summary: We present the discovery of TOI-1518b — an ultra-hot Jupiter orbiting a bright star $V = 8.95$. The transiting planet is confirmed using high-resolution optical transmission spectra from EXPRES. It is […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Michael R. R. Good, Eric V Linder, Frank Wilczek, , | Summary: A new solution for an analytic spectrum of particle creation by an accelerating mirror (dynamical Casimir effect) is given. It is the first model to simultaneously radiate thermally and emit a finite number of particles. […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Karna A. Morey, Anna-Christina Eilers, Frederick B. Davies, Joseph F. Hennawi, Robert A. Simcoe | Summary: The lifetime of quasars can be estimated by means of their proximity zone sizes, which are regions of enhanced flux bluewards of the Lyman-$alpha$ emission line observed in the rest-frame […]
Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Daniel Huber, Timothy R. White, Travis S. Metcalfe, Ashley Chontos, Michael M. Fausnaugh | Summary: We present an analysis of the first 20-second cadence light curves obtained by the TESS space telescope during its extended mission. We find a precision improvement of 20-second data compared to […]
Kavli Affiliate: Sara Seager | First 5 Authors: Jane S. Greaves, Paul B. Rimmer, Anita M. S. Richards, Janusz J. Petkowski, William Bains | Summary: New analysis is presented of the 1.1 mm wavelength absorption lines in Venus’ atmosphere that suggested the presence of phosphine. We retrieve a sulphur dioxide observation from the JCMT archive […]
Kavli Affiliate: Jacqueline Hewitt | First 5 Authors: The HERA Collaboration, Zara Abdurashidova, James E. Aguirre, Paul Alexander, Zaki Ali | Summary: Recently, the Hydrogen Epoch of Reionization Array (HERA) collaboration has produced the experiment’s first upper limits on the power spectrum of 21-cm fluctuations at z~8 and 10. Here, we use several independent theoretical […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Trifon Trifonov, Rafael Brahm, Nestor Espinoza, Thomas Henning, Andrés Jordán | Summary: TOI-2202 b is a transiting warm Jovian-mass planet with an orbital period of P=11.91 days identified from the Full Frame Images data of five different sectors of the TESS mission. Ten TESS transits of […]
Kavli Affiliate: Erin A. Kara | First 5 Authors: Christopher S. Reynolds, Robyn N. Smith, Andrew C. Fabian, Yasushi Fukazawa, Erin A. Kara | Summary: NGC1275 is the Brightest Cluster Galaxy (BCG) in the Perseus cluster and hosts the active galactic nucleus (AGN) that is heating the central 100,kpc of the intracluster medium (ICM) atmosphere […]
