Kavli Affiliate: Luis C. Ho | First 5 Authors: Bingcheng Jin, Bingcheng Jin, , , | Summary: We study the rest-frame ultraviolet-optical color gradients of 441 galaxies at $4<z<8$ by characterizing the wavelength dependence of their structural parameters derived from simultaneously fitting the seven-band NIRCam images acquired with the James Webb Space Telescope. Distinct from […]
Kavli Affiliate: Jing Wang | First 5 Authors: Da Song, Hong-bo Cai, Shen Wang, Jing Wang, | Summary: Impact flashes on the moon are caused by high-speed collisions of celestial bodies with the lunar surface. The study of the impacts is critical for exploring the evolutionary history and formation of the Moon, and for quantifying […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Alexander Saffer, Emmanuel Fonseca, Scott Ransom, Ingrid Stairs, Ryan Lynch | Summary: The binary pulsar J0348+0432 was previously shown to have a mass of approximately 2,${rm M_odot}$, based on the combination of radial-velocity and model-dependent mass parameters derived from high-resolution optical spectroscopy of its white-dwarf companion. […]
Kavli Affiliate: Sara Seager | First 5 Authors: Romy Rodriguez Martinez, Jason D. Eastman, Karen Collins, Joseph Rodriguez, David Charbonneau | Summary: We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite (TESS). TOI-4994b transits a G-type star (V = 12.6 mag) with […]

Kavli Affiliate: George Efstathiou | First 5 Authors: Emma Shen, Dominic Anstey, Marta Spinelli, Eloy de Lera Acedo, Anastasia Fialkov | Summary: The precise measurement of the sky-averaged HI absorption signal between 50 and 200 MHz is the primary goal of global 21-cm cosmology. This measurement has the potential to unravel the underlying physics of […]
Kavli Affiliate: Kaisey Mandel | First 5 Authors: The Multimodal Universe Collaboration, Jeroen Audenaert, Micah Bowles, Benjamin M. Boyd, David Chemaly | Summary: We present the MULTIMODAL UNIVERSE, a large-scale multimodal dataset of scientific astronomical data, compiled specifically to facilitate machine learning research. Overall, the MULTIMODAL UNIVERSE contains hundreds of millions of astronomical observations, constituting […]
Kavli Affiliate: George Ricker | First 5 Authors: Marcelo Tala Pinto, Andrés Jordán, Lorena Acuña, Matías Jones, Rafael Brahm | Summary: We report the discovery and characterization of three new transiting giant planets orbiting TOI-6628, TOI-3837 and TOI-5027, and one new warm sub-Saturn orbiting TOI-2328, whose transits events were detected in the lightcurves of the […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Ian Holst, Gordan Krnjaic, Huangyu Xiao, , | Summary: If primordial black holes (PBH) are present in the early universe, their contribution to the energy budget grows relative to that of radiation and generically becomes dominant unless the initial abundance is exponentially small. This black hole domination […]
