Early auditory and adult mating experiences interact with singer identity to shape neural responses to song in female zebra finches

Posted by dbos Columbia, This Week: Neuroscience

Kavli Affiliate: Sarah Woolley | Authors: Isabella Catalano and Sarah C Woolley | Summary: Social and sensory experiences across the lifespan can shape social interactions, however, experience-dependent plasticity is widely studied within discrete life stages. In the socially monogamous zebra finch, in which females use learned vocal signals to identify individuals and form long-lasting pair […]

A long spin period for a sub-Neptune-mass exoplanet

Posted by dbos MIT, This Week: Astrophysics

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Ellen M. Price, Juliette Becker, Zoë L. de Beurs, Leslie A. Rogers, Andrew Vanderburg | Summary: HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital period and deep transit make it an ideal candidate for detecting oblateness photometrically. We present a […]

Age-dating early quiescent galaxies: high star-formation efficiency, but consistent with direct, higher-redshift observations

Posted by dbos Cambridge, This Week: Astrophysics

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Crispin Turner, Sandro Tacchella, Francesco D’Eugenio, Stefano Carniani, Mirko Curti | Summary: We present a detailed analysis of JWST/NIRSpec and NIRCam observations of ZF-UDS-7329, a massive, quiescent galaxy at redshift $z=3.2$, which has been put forward to challenge cosmology and galaxy formation physics. Our study extends previous […]

Tomographic constraint on anisotropic cosmic birefringence

Posted by dbos This Week: Astrophysics, Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, , , , | Summary: We for the first time constrain anisotropic cosmic birefringence generated at reionization using Planck PR4 polarization data. Several recent analyses of WMAP and Planck polarization data have found a tantalizing hint of isotropic cosmic birefringence. Ongoing and future CMB experiments […]

Classification of radio backgrounds at cosmic dawn and 21-cm signal confirmation using neural networks

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Anastasia Fialkov, Rennan Barkana, , | Summary: Several ongoing and upcoming radio telescopes aim to detect either the global 21-cm signal or the 21-cm power spectrum. The extragalactic radio background, as detected by ARCADE-2 and LWA-1, suggests a strong radio background from cosmic dawn, which […]

LHAASO detection of very-high-energy gamma-ray emission surrounding PSR J0248+6021

Posted by dbos Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: We report the detection of an extended very-high-energy (VHE) gamma-ray source coincident with the locations of middle-aged (62.4~rm kyr) pulsar PSR J0248+6021, by using the LHAASO-WCDA data of live 796 days and LHAASO-KM2A data […]

Discovering Cognitive Strategies with Tiny Recurrent Neural Networks

Posted by dbos UCSD / Salk

Kavli Affiliate: Marcelo Mattar | Authors: Li Ji-An, Marcus K Benna and Marcelo G Mattar | Summary: Normative modeling frameworks such as Bayesian inference and reinforcement learning provide valuable insights into the fundamental principles governing adaptive behavior. While these frameworks are valued for their simplicity and interpretability, their reliance on few parameters often limits their […]
