Bayesian constraints on quark stars from multi-messenger observations

Posted by klaurent Peking

Kavli Affiliate: Renxin Xu | Summary:We perform a systematic Bayesian analysis of quark star equations of state under current multimessenger constraints, investigating the impact of prior assumptions and extreme-mass observations. Quark matter is modeled within an interacting MIT bag framework that consistently accommodates color-superconducting phases (2SC, 2SC+s, and CFL) and perturbative QCD corrections. We find […]

The diffuse supernova neutrino background: an update with modern population synthesis and core-collapse simulations

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | Summary:We present a new, state-of-the-art computation of the Diffuse Supernova Neutrino Background (DSNB), where we use neutrino spectra from multi-dimensional, multi-second core collapse supernova simulations – including both neutron-star and black-hole forming collapses – and binary evolution effects from modern population synthesis codes. Large sets of numerical results are processed […]

Residual Matrix Transformers: Scaling the Size of the Residual Stream

Posted by klaurent Cornell

Kavli Affiliate: Kinfai Mak | First 5 Authors: Brian Mak, Brian Mak, , , | Summary: The residual stream acts as a memory bus where transformer layers both store and access features (Elhage et al., 2021). We consider changing the mechanism for retrieving and storing information in the residual stream, and replace the residual stream […]

Unconventional superlattice ordering in intercalated transition metal dichalcogenide V$_1/3$NbS$_2$

Posted by klaurent Berkeley

Kavli Affiliate: Kwabena Bediako| Summary:The interplay between symmetry and topology in magnetic materials makes it possible to engineer exotic phases and technologically useful properties. A key requirement for these pursuits is achieving control over local crystallographic and magnetic structure, usually through sample morphology (such as synthesis of bulk crystals versus thin-films) and application of magnetic […]

Fundamental Nuclear and Particle Physics At Neutron Sources

Posted by klaurent Tokyo

Kavli Affiliate: Yevgeny Stadnik | Summary:Fundamental neutron and neutrino physics at neutron sources, combining precision measurements and theory, can probe new physics at energy scales well beyond the highest energies probed by the LHC and possible future high energy collider facilities. The European Spallation Source (ESS) will in the not too far future be a […]

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 klaurent Chicago

Kavli Affiliate: Emil 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 coset $mathcalG/mathcalH$, where $mathcalG = PSU(1,1 times mathbb R^5,1$ and $mathcalH=U(1) times U(1)$. […]
