Kilonova constraints for the LIGO/Virgo/KAGRA neutron star merger candidate S250206dm: GW-MMADS observations

Posted by dbos Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Lei Hu, Tomás Cabrera, Antonella Palmese, James Freeburn, Mattia Bulla | Summary: Gravitational wave (GW) neutron star mergers with an associated electromagnetic counterpart constitute powerful probes of binary evolution, the production sites of heavy elements, general relativity, and the expansion of the universe. Only a handful […]

Ecological Factors Affecting Prosociality in Marmoset Monkeys

Posted by dbos UCSD / Salk

Kavli Affiliate: Cory Miller | Authors: Anand R Mysorekar, Anushka Vispute and Cory Miller | Summary: Prosocial behaviors, such as cooperation and food sharing, are critical for maintaining group cohesion in social species, yet the influence of transient physiological states on these behaviors remains poorly understood. This study investigates how short-term ecological factors impact social […]

On the string theory of a single NS5-brane

Posted by dbos Chicago

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Andrea Dei, Emil J. Martinec, , , | Summary: We formulate a worldsheet description of string theory in the background of a single decoupled NS5-brane, which is a particularly simple example of “little string” holography. The worldsheet theory involves a gauged Wess-Zumino-Witten model for the group […]

Apache Point Observatory follow-up of ACcelerating Candidate ExopLanet host Stars (APO ACCELS): Ages for 166 Accelerating Stars in the Northern Hemisphere

Posted by klaurent Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Anne E. Peck, Anne E. Peck, , , | Summary: Directly imaged substellar companions with well-constrained ages and masses serve as vital empirical benchmarks for planet formation and evolution models. Potential benchmark companions can be identified from astrometric accelerations of their host stars. We use Gaia DR3 […]

Increasing single-photon production with cavity-QED

Posted by UCSB

Kavli Affiliate: John E. Bowers | First 5 Authors: Chen Shang, Weng W. Chow, Galan Moody, John E. Bowers, | Summary: A study was performed to determine the extent cavity enhancement may increase single-photon production while maintaining single-photon purity. It was found that certain combinations of cavity lifetime and light-matter coupling strength can lead to […]

Humans share acoustic preferences with other animals

Posted by dbos Columbia

Kavli Affiliate: Sarah Woolley | Authors: Logan S James, Sarah C Woolley, Jon T Sakata, Courtney B Hilton, Michael J Ryan and Samuel A Mehr | Summary: Many animals produce sounds during courtship, and receivers prefer some sounds over others. Shared ancestry and convergent evolution may generate similarities in preference across species and could underlie […]

TDCOSMO XXIII. First spatially resolved kinematics of the lens galaxy obtained using JWST-NIRSpec to improve time-delay cosmography

Posted by dbos Chicago

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Tommaso Treu, Sherry H. Suyu, David Law, Akın Yıldırım | Summary: Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and, in turn, provide a precise constraint on the Hubble constant […]

Mapping the projectional architecture of the mouse midbrain dopaminergic system using cell type-specific barcoding

Posted by dbos Hopkins

Kavli Affiliate: Justus M Kebschull | Authors: Hyopil Kim, Cheng Xu, Craig Washington, Maggie Lowmann and Justus M Kebschull | Summary: Brain-wide neural circuits are formed by the diverse axonal branching patterns of many individual neurons. Here we introduce POINTseq (projections of interest by sequencing), a high-throughput and user-friendly barcoded connectomics method that uses cell […]

Sifting for a Stream: The Morphology of the $300S$ Stellar Stream

Posted by dbos Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Benjamin Cohen, Alexander P. Ji, Peter S. Ferguson, Sergey E. Koposov, Alex Drlica-Wagner | Summary: Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy’s gravitational field. Here, we analyze the morphology of the $300S$ stellar stream, which has an eccentric, retrograde orbit […]
