Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Ralf K. Heilmann, David P. Huenemoerder, Jake A. McCoy, Randall L. McEntaffer, | Summary: X-ray diffraction gratings play an essential role in high-resolution spectroscopy of astrophysical phenomena. We present some scientific highlights from the X-ray grating spectrometers (XGS) on board of the Chandra and XMM/Newton missions, […]
Kavli Affiliate: Erin Kara | First 5 Authors: Margherita Giustini, Giovanni Miniutti, Riccardo Arcodia, Adelle Goodwin, Kate D. Alexander | Summary: Quasi-periodic eruptions (QPEs) are an extreme X-ray variability phenomenon associated with low-mass supermassive black holes. First discovered in the nucleus of the galaxy GSN 069, they have been so far securely detected in five […]
Kavli Affiliate: Sara Seager | First 5 Authors: Daniel Duzdevich, Collin Nisler, Janusz J. Petkowski, William Bains, Caroline K. Kaminsky | Summary: Venus has become a target of astrobiological interest because it is physically accessible to direct exploration, unlike exoplanets. So far this interest has been motivated not by the explicit expectation of finding life […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mary Anne Limbach, Andrew Vanderburg, Alexander Venner, Simon Blouin, Kevin B. Stevenson | Summary: The MIRI Exoplanets Orbiting White dwarfs (MEOW) Survey is a cycle 2 JWST program to search for exoplanets around dozens of nearby white dwarfs via infrared excess and direct imaging. In this paper, […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Shubham Kanodia, Arvind F. Gupta, Caleb I. Canas, Lia Marta Bernabo, Varghese Reji | Summary: Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasingly large number of them […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Desika Narayanan, Daniel P. Stark, Steven L. Finkelstein, Paul Torrey, Qi Li | Summary: JWST has enabled the detection of the UV continuum of galaxies at z>10, evidencing a population of extremely blue, potentially dust-free galaxies. Interpreting the UV spectra of galaxies as they redden is complicated […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ketan R. Sand, Alice P. Curtin, Daniele Michilli, Victoria M. Kaspi, Emmanuel Fonseca | Summary: We present a spectro-temporal analysis of 137 fast radio bursts (FRBs) from the first CHIME/FRB baseband catalog, including 125 one-off bursts and 12 repeat bursts, down to microsecond resolution using the […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Amanda M. Cook, Paul Scholz, Aaron B. Pearlman, Thomas C. Abbott, Marilyn Cruces | Summary: We present an extensive contemporaneous X-ray and radio campaign performed on the repeating fast radio burst (FRB) source FRB 20220912A for eight weeks immediately following the source’s detection by CHIME/FRB. This […]
