Disk-to-Corona State Transition and Extreme X-ray Variability in the Tidal Disruption Event AT2019teq

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | Summary:We present a five-year X-ray spectral and timing analysis of the optically selected Tidal Disruption Event (TDE) AT2019teq, which displays extreme variability, including order-of-magnitude changes in flux on minute-to-day timescales, and a rare late-time emergence of hard X-ray emission leading to the longest-lived corona in a known TDE. In one […]

The early Universe with JWST and ALMA

Posted by klaurent Tokyo

Kavli Affiliate: John Silverman | Summary:The Atacama Large Millimeter/submillimeter Array and the James Webb Space Telescope are transforming our understanding of galaxy formation and evolution in the early Universe. By combining their capabilities, these observatories provide unprecedented insights into the gas, dust, and stars of high-redshift galaxies at spatially resolved scales, unveiling the complexities of […]

Dopaminergic Modulation of Mushroom Body Output Neurons Mediates Nociception-Induced Escape in Drosophila

Posted by dbos UCSD / Salk

Kavli Affiliate: Ann-Shyn Chiang | Authors: Chi-Lien Yang, Chia-Wen Chen, Kuan-Lin Feng, Hsiao-Chien Peng, Ming-Chin Wu, Ching-Che Charng, Li-An Chu, Yeong-Ray Wen and Ann-Shyn Chiang | Summary: In Drosophila, noxious heat is detected by peripheral nociceptors expressing transient receptor potential (TRP) channels, including Painless and TrpA1, and rapidly triggers escape behavior. Although peripheral transduction has […]

A spectroscopically confirmed, strongly lensed, metal-poor Type II supernova at z = 5.13

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | Summary:Observing supernovae (SNe) in the early Universe (z > 3) provides a window into how both galaxies and individual stars have evolved over cosmic time, yet a detailed study of high-redshift stars and SNe has remained difficult due to their extreme distances and cosmological redshifting. To overcome the former, searches […]

Solvent Effects on Triplet Yields in BODIPY-Based Photosensitizers

Posted by klaurent Berkeley

Kavli Affiliate: David T. Limmer | Summary:We employ molecular dynamics simulations and quantum rate theories to elucidate the complex condensed-phase dynamics underpinning triplet-state formation in organic photosensitizers. Using models informed by first-principles calculations complete with a molecular representation of solvents of different polarities, we elucidate the interplay of the internal and environmental interactions underlying triplet […]

Roadmap for Condensates in Cell Biology

Posted by klaurent Delft

Kavli Affiliate: Liedewij Laan | Summary:Biomolecular condensates govern essential cellular processes yet elude description by traditional equilibrium models. This roadmap, distilled from structured discussions at a workshop and reflecting the consensus of its participants, clarifies key concepts for researchers, funding bodies, and journals. After unifying terminology that often separates disciplines, we outline the core physics […]
