NIRCam yells at cloud: JWST MIRI imaging can directly detect exoplanets of the same temperature, mass, age, and orbital separation as Saturn and Jupiter

Posted by dbos MIT

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 […]

On the creation of narrow AI: hierarchy and nonlocality of neural network skills

Posted by dbos MIT

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 […]

Sequential Interval Passing for Compressed Sensing

Posted by dbos Chicago

Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, Remi Chou, Taejoon Kim, , | Summary: The reconstruction of sparse signals from a limited set of measurements poses a significant challenge as it necessitates a solution to an underdetermined system of linear equations. Compressed sensing (CS) deals with sparse signal reconstruction using techniques such […]

The Long Road to Alignment: Measuring Black Hole Spin Orientation with Expanding Gravitational-Wave Datasets

Posted by dbos MIT

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 […]

First Identification and Precise Spectral Measurement of the Proton Component in the Cosmic-Ray `Knee’

Posted by dbos Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: The LHAASO Collaboration, Zhen Cao, , , | Summary: We report the first high-purity identification of cosmic-ray (CR) protons and a precise measurement of their energy spectrum from 0.15 to 12 PeV using the Large High Altitude Air Shower Observatory (LHAASO). Abundant event statistics, combined with the […]

Origin of the X-ray emission in blazars through multiwavelength polarization

Posted by dbos Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Ioannis Liodakis, Haocheng Zhang, Stella Boula, Riccardo Middei, Jorge Otero-Santos | Summary: The origin of the high-energy emission in astrophysical jets from black holes is a highly debated issue. This is particularly true for jets from supermassive black holes that are among the most powerful particle […]

ALMA observation of evolving magnetized corona in the radio-quiet changing-state AGN NGC 1566

Posted by dbos Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Arghajit Jana, Claudio Ricci, Sophie M. Venselaar, Chin-Shin Chang, Mai Liao | Summary: The origin of compact millimeter (mm) continuum emission from radio-quiet AGNs (RQAGNs) is still not fully understood. Changing-state AGNs (CSAGNs) display rapid and strong variability, which can allow us to investigate the origin of […]
