Kavli Affiliate: Moritz Guenther | First 5 Authors: Attila Varga, Joel H. Kastner, Alexander S. Binks, Hans Moritz Guenther, Simon J. Murphy | Summary: The mid-M star TOI~1227 hosts among the youngest known transiting exoplanets. We have conducted new X-ray imaging and optical spectroscopic observations of TOI 1227 aimed at ascertaining its age and the […]
Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Joseph D. Twicken, Jon M. Jenkins, Douglas A. Caldwell, Benjamin M. Tofflemire, Marziye Jafariyazani | Summary: We report the delivery to the Mikulski Archive for Space Telescopes (MAST) of tables containing Root Mean Square (RMS) Combined Differential Photometric Precision (CDPP) values for all TESS 2-min cadence […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Laurel White, Michael McDonald, Francesco Ubertosi, Massimo Gaspari, Julie Hlavacek-Larrondo | Summary: We present a new 8.5 ks Chandra observation of Abell 1885, obtained as part of the Cluster Evolution Reference Ensemble At Low-z (CEREAL) survey of ~200 low-z galaxy groups and clusters. These data reveal that […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Daichi Kashino, Simon J. Lilly, Jorryt Matthee, Ruari Mackenzie, Anna-Christina Eilers | Summary: We present a comprehensive analysis of the relationship between galaxies and the intergalactic medium (IGM) during the late stages of cosmic reionization, based on the complete JWST EIGER dataset. Using deep NIRCam $3.5,mathrm{mu […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: Megumi Shidatsu, Yukikatsu Terada, Takashi Kominato, So Kato, Ryohei Sato | Summary: We report the results from the ground and on-orbit verifications of the XRISM timing system when the satellite clock is not synchronized to the GPS time. In this case, the time is determined by […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Emanuele Berti, Vitor Cardoso, Gregorio Carullo, Jahed Abedi, Niayesh Afshordi | Summary: The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes and comparing them with gravitational-wave data from compact binary mergers […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Jeremy D. Schnittman, , , | Summary: Even when used to describe the same phenomenon, equations, graphics and words each give different perspectives and lead to complementary insights. The basic elements of strong gravitational lensing are introduced here favoring words and graphics over […]

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Lydia Makrygianni, Iair Arcavi, Megan Newsome, Ananya Bandopadhyay, Eric R. Coughlin | Summary: Flares produced following the tidal disruption of stars by supermassive black holes can reveal the properties of the otherwise dormant majority of black holes and the physics of accretion. In the past decade, a […]
