Central densities of dark matter halos in FIRE-2 simulations of low-mass galaxies with cold dark matter and self-interacting dark matter

Posted by dbos MIT

Kavli Affiliate: Lina Necib | First 5 Authors: Maria C. Straight, Michael Boylan-Kolchin, James S. Bullock, Philip F. Hopkins, Xuejian Shen | Summary: We investigate the central density structure of dark matter halos in cold dark matter (CDM) and self-interacting dark matter (SIDM) models using simulations that are part of the Feedback In Realistic Environments […]

Open Problems in Mechanistic Interpretability

Posted by dbos MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Lee Sharkey, Bilal Chughtai, Joshua Batson, Jack Lindsey, Jeff Wu | Summary: Mechanistic interpretability aims to understand the computational mechanisms underlying neural networks’ capabilities in order to accomplish concrete scientific and engineering goals. Progress in this field thus promises to provide greater assurance over AI system behavior […]

Cosmological Consequences of Domain Walls Biased by Quantum Gravity

Posted by dbos Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Yann Gouttenoire, Stephen F. King, Rishav Roshan, Xin Wang, Graham White | Summary: One of the simplest standard model extensions leading to a domain wall network is a real scalar $S$ with a $mathcal{Z}_2$ symmetry spontaneously broken during universe evolution. Motivated by the swampland program, we explore […]

The Ophiuchus DIsk Survey Employing ALMA (ODISEA): Complete Size Distributions for the 100 Brightest Disks Across Multiplicity and SED Classes

Posted by dbos Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anuroop Dasgupta, Lucas A. Cieza, Camilo I. Gonzalez Ruilova, Trisha Bhowmik, Ms. Prachi Chavan | Summary: The size of a protoplanetary disk is a fundamental property, yet most remain unresolved, even in nearby star-forming regions (d $sim$ 140-200 pc). We present the complete continuum size distribution […]

Three-dimensional core-collapse supernova models with phenomenological treatment of neutrino flavor conversions

Posted by dbos Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi, | Summary: We perform three-dimensional supernova simulations with a phenomenological treatment of neutrino flavor conversions. We show that the explosion energy can increase to as high as ~10^51 erg depending on the critical density for the onset of flavor […]

Atomic collapse in gapped graphene: lattice and valley effects

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Xiaotai Wu, Wen-Sheng Zhao, Yuhua Cheng, Yue Hu | Summary: We study the atomic collapse phenomenon in $K$ and $K’$ valley of gapped graphene. Bound states induced by Coulomb impurity in the gap turn into atomic collapse resonances as the charge increases beyond the supercritical […]
