Kavli Affiliate: Avi Shporer | First 5 Authors: Patrick Tamburo, Patrick Tamburo, , , | Summary: TOI-3884~b is an unusual 6.4~R$_oplus$ planet orbiting an M4 host, whose transits display large and persistent spot-crossing events. We used the textitTierras Observatory to monitor both the long-term photometric variability of TOI-3884 and changes in the spot-crossing events across […]
Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, William Bains, , | Summary: Thousands of exoplanets orbit nearby stars, showcasing a remarkable diversity in mass, size, and orbits. With the James Webb Space Telescope now operational, we are observing exoplanet atmospheres and aiming to reach down to small, habitable-zone exoplanets […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: CHIME Collaboration, Mandana Amiri, Arnab Chakraborty, Simon Foreman, Mark Halpern | Summary: We report the detection of a new HI absorption system associated with the radio source NVSS J164725+375218 at a redshift of z=2.327, identified through a blind survey conducted by the Canadian Hydrogen Intensity Mapping […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Alice P. Curtin, Shion Andrew, Sunil Simha, Alice Cai, Kenzie Nimmo | Summary: On 2024 December 28, CHIME/FRB detected the thus-far non-repeating FRB 20241228A with a real-time signal-to-noise ratio of $>50$. Approximately 112~s later, the X-ray Telescope onboard the Neil Gehrels Swift Observatory was on source, […]
Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Eleonora Polini, Piotr Chruściel, Georgi Dvali, Christopher Hilweg, Begüm Kabagöz | Summary: In this contribution, we describe the status of our experiment aimed at measuring the gravitationally induced phase shift on path-entangled photons. We use a kilometer-scale fiber interferometer whose arms are vertically displaced in the Earth […]

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Christian E. A. Chapman-Bird, Lorenzo Speri, Zachary Nasipak, Ollie Burke, Michael L. Katz | Summary: Observations of gravitational-wave signals emitted by compact binary inspirals provide unique insights into their properties, but their analysis requires accurate and efficient waveform models. Intermediate- and extreme-mass-ratio inspirals (I/EMRIs), with mass […]

Kavli Affiliate: Erin Kara | First 5 Authors: Missagh Mehdipour, Jelle S. Kaastra, Megan E. Eckart, Liyi Gu, Ralf Ballhausen | Summary: We present our study of the XRISM observation of the Seyfert-1 galaxy NGC 3783. For the first time, XRISM’s Resolve microcalorimeter enables a detailed characterization of the highly ionized outflows in this active […]
