Kavli Affiliate: Lina Necib | First 5 Authors: Tri Nguyen, Francisco Villaescusa-Navarro, Siddharth Mishra-Sharma, Carolina Cuesta-Lazaro, Paul Torrey | Summary: The connection between galaxies and their host dark matter (DM) halos is critical to our understanding of cosmology, galaxy formation, and DM physics. To maximize the return of upcoming cosmological surveys, we need an accurate […]

Kavli Affiliate: David P. Huenemoerder | 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: 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 […]
