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 […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Rachel Bowens-Rubin, James Mang, Mary Anne Limbach, Aarynn L. Carter, Kevin B. Stevenson | Summary: NIRCam and MIRI coronagraphy have successfully demonstrated the ability to directly image young sub-Jupiter mass and mature gas-giant exoplanets. However, these modes struggle to reach the sensitivities needed to find the population […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Eric J. Michaud, Asher Parker-Sartori, Max Tegmark, , | Summary: We study the problem of creating strong, yet narrow, AI systems. While recent AI progress has been driven by the training of large general-purpose foundation models, the creation of smaller models specialized for narrow domains could be […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Salvatore Vitale, Matthew Mould, , , | Summary: Measuring the distribution of spin tilts-the angles between the spin vectors and the binary orbital angular momentum-in stellar-mass binary black holes detected by LIGO-Virgo-KAGRA would provide valuable insight into their astrophysical origins. Analyses of the 69 binary black holes […]
Kavli Affiliate: Moritz Guenther | First 5 Authors: Nancy Remage Evans, Alexandre Gallenne, Pierre Kervella, H. Moritz Guenther, Joanna Kuraszkiewicz | Summary: The system V350 Sgr has a classical Cepheid for the primary. Interferometry is presented for the system and the full orbit is determined. The mass of the companion has been determined from an […]
