EEG responses to rapidly unfolding stochastic sounds reflect precision tracking

Posted by dbos January 9, 2024January 22, 2024Hopkins

Kavli Affiliate: Mounya Elhilali | Authors: Sijia Zhao, Benjamin Skerritt-Davis, Mounya Elhilali, Frederic Dick and Maria Chait | Summary: The brain is increasingly viewed as a statistical learning machine, where our sensations and decisions arise from the intricate interplay between bottom-up sensory signals and constantly changing expectations regarding the surrounding world. Which statistics does the […]

On the Physical Nature of Ly$α$ Transmission Spikes in High Redshift Quasar Spectra

Posted by klaurent January 9, 2024Chicago

Kavli Affiliate: Nickolay Gnedin | Summary:We investigate Lyman-alpha (Ly$α$) transmission spikes at $5.2 < z < 6.8$ using synthetic quasar spectra from the “Cosmic Reionization On Computers" simulations. We focus on understanding the relationship between these spikes and the properties of the intergalactic medium (IGM). Disentangling the complex interplay between IGM physics and the influence […]

Detection of X-ray Polarization from the Blazar 1ES 1959+650 with the Imaging X-ray Polarimetry Explorer

Posted by klaurent January 9, 2024Stanford

Kavli Affiliate: Grzegorz Madejski | Summary:Observations of linear polarization in the 2-8 keV energy range with the Imaging X-ray Polarimetry Explorer (IXPE) explore the magnetic field geometry and dynamics of the regions generating non-thermal radiation in relativistic jets of blazars. These jets, particularly in blazars whose spectral energy distribution peaks at X-ray energies, emit X-rays […]
