From Morphology to Computation: How Synaptic Organization Shapes Place Fields in CA1 Pyramidal Neurons

Posted by dbos June 3, 2025June 9, 2025Columbia, This Week: Neuroscience

Kavli Affiliate: Attila Losonczy | Authors: Simone Tasciotti, Daniel Maxim Iascone, Spyridon Chavlis, Luke Hammond, Yardena Katz, Attila Losonczy, Franck Polleaux and Panayiota Poirazi | Summary: The synaptic mechanisms driving feature selectivity in specific neuron types remains a fundamental and unresolved challenge in neuroscience. In hippocampal CA1 pyramidal neurons (PNs), the development of place selectivity, […]

ViT-Split: Unleashing the Power of Vision Foundation Models via Efficient Splitting Heads

Posted by dbos June 3, 2025June 9, 2025Peking, This Week: Astrophysics

Kavli Affiliate: Li Xin Li | First 5 Authors: Yifan Li, Xin Li, Tianqin Li, Wenbin He, Yu Kong | Summary: Vision foundation models (VFMs) have demonstrated remarkable performance across a wide range of downstream tasks. While several VFM adapters have shown promising results by leveraging the prior knowledge of VFMs, we identify two inefficiencies […]

Revisiting Isocurvature Bounds on the Minimal QCD Axion

Posted by dbos June 3, 2025June 9, 2025Stanford, This Week: Astrophysics

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Davide Racco, , , | Summary: The QCD axion has important connections to early universe cosmology. For example, it is often said that isocurvature limits rule out a combination of high axion decay constant, $f_a$, and high inflationary Hubble scale, $H_I$. High scales […]

The Onset of Feedback in Abell 1885: Evidence for Large-Scale Quenching Despite a Young Central AGN

Posted by dbos June 3, 2025June 9, 2025MIT, This Week: Astrophysics

Kavli Affiliate: Michael McDonald | First 5 Authors: Laurel White, Michael McDonald, Francesco Ubertosi, Massimo Gaspari, Julie Hlavacek-Larrondo | Summary: We present a new 8.5 ks Chandra observation of Abell 1885, obtained as part of the Cluster Evolution Reference Ensemble At Low-z (CEREAL) survey of ~200 low-z galaxy groups and clusters. These data reveal that […]

The Pandora project. II: how non-thermal physics drives bursty star formation and temperate mass-loaded outflows in dwarf galaxies

Posted by dbos June 3, 2025June 9, 2025Cambridge, This Week: Astrophysics

Kavli Affiliate: Debora Sijacki | First 5 Authors: Sergio Martin-Alvarez, Debora Sijacki, Martin G. Haehnelt, Alice Concas, Yuxuan Yuan | Summary: Dwarf galaxies provide powerful laboratories for studying galaxy formation physics. Their early assembly, shallow gravitational potentials, and bursty, clustered star formation histories make them especially sensitive to the processes that regulate baryons through multi-phase […]

Cavity-mediated cross-cross-resonance gate

Posted by dbos June 3, 2025June 9, 2025Caltech, This Week: Nanoscience

Kavli Affiliate: Oskar Painter | First 5 Authors: Alexey V. Gorshkov, Daniel Cohen, Arbel Haim, Amit Rotem, Or Golan | Summary: We propose a cavity-mediated gate between two transmon qubits or other nonlinear superconducting elements. The gate is realized by driving both qubits at a frequency that is near-resonant with the frequency of the cavity. […]

EIGER VII. The evolving relationship between galaxies and the intergalactic medium in the final stages of reionization

Posted by dbos June 3, 2025June 9, 2025MIT, This Week: Astrophysics

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Daichi Kashino, Simon J. Lilly, Jorryt Matthee, Ruari Mackenzie, Anna-Christina Eilers | Summary: We present a comprehensive analysis of the relationship between galaxies and the intergalactic medium (IGM) during the late stages of cosmic reionization, based on the complete JWST EIGER dataset. Using deep NIRCam $3.5,mathrm{mu […]

TDCOSMO 2025: Cosmological constraints from strong lensing time delays

Posted by dbos June 3, 2025June 9, 2025Chicago, This Week: Astrophysics

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer, Michele Cappellari, Frédéric Courbin | Summary: We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar velocity dispersions measured from spectra obtained with the James Webb […]

Verification of the Timing System for the X-ray Imaging and Spectroscopy Mission in the GPS Unsynchronized Mode

Posted by dbos June 3, 2025June 9, 2025MIT, This Week: Astrophysics

Kavli Affiliate: Eric D. Miller | First 5 Authors: Megumi Shidatsu, Yukikatsu Terada, Takashi Kominato, So Kato, Ryohei Sato | Summary: We report the results from the ground and on-orbit verifications of the XRISM timing system when the satellite clock is not synchronized to the GPS time. In this case, the time is determined by […]
