Exploring Ultralight Scalar Assistance in Sterile Neutrino Dark Matter: Cold Spectrum and Unusual X/Gamma-ray Signatures

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Yuxuan He, Jia Liu, Xiaolin Ma, Xiao-Ping Wang, | Summary: We present a scalar-driven sterile neutrino production model where the interaction with the ultralight scalar field modifies the oscillation production of sterile neutrinos in the early universe. The model effectively suppresses the production of sterile neutrinos at […]

Social experiences shape song preference learning independent of developmental exposure to song

Posted by klaurent Columbia

Kavli Affiliate: Sarah Woolley | Authors: Erin Mckenzie Wall and Sarah Cushing Woolley | Summary: Communication governs the formation and maintenance of social relationships. The interpretation of communication signals depends not only on the signal’s content, but also on a receiver’s individual experience. Experiences throughout life may interact to affect behavioral plasticity, such that a […]

Allosteric regulation of TRPV1 by the inflammatory lipid, LPA

Posted by klaurent UCSF

Kavli Affiliate: Yifan Cheng | Authors: William Randall Arnold, David Julius and Yifan Cheng | Summary: Transient Receptor Potential Vanilloid 1 (TRPV1) is a tetrameric cation channel expressed in primary afferent neurons, where it contributes to thermosensation and nociception. TRPV1 is a polymodal signal integrator that responds not only to heat, but also to inflammatory […]

Entangled Photon Correlations Allow a Continuous-Wave Laser Diode to Measure Single Photon, Time-Resolved Fluorescence

Posted by klaurent Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Nathan Harper, Bryce P. Hickam, Manni He, Scott K. Cushing, | Summary: Fluorescence lifetime experiments are a standard approach for measuring excited state dynamics and local environment effects. Here, we show that entangled photon pairs produced from a continuous-wave (CW) laser diode can replicate pulsed laser […]

Mini-Quenching of High-Redshift Galaxies by Bursty Star Formation

Posted by klaurent Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Sandro Tacchella, Anastasia Fialkov, Avishai Dekel, Omri Ginzburg | Summary: The recent observation of a low-mass $z=5.2$ and an intermediate-mass $z=7.3$ (JADES-GS-z7-01-QU) quenched galaxy with JWST / NIRSpec is the first evidence of halted star formation above $zsim 5$. Here we show how bursty star […]

Vibrations and tunneling of strained nanoribbons at finite temperature

Posted by klaurent UCSB

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Paul Z. Hanakata, Sourav S. Bhabesh, David Yllanes, David R. Nelson, Mark J. Bowick | Summary: Crystalline sheets (e.g., graphene and transition metal dichalcogenides) liberated from a substrate are a paradigm for materials at criticality because flexural phonons can fluctuate into the third dimension. Although studies […]
