A Study of Afterglow Signatures in NaI and CsI Scintillator Modules for the Background and Transient Observer Instrument on COSI

Posted by klaurent January 27, 2025Tokyo

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hannah Gulick, Hiroki Yoneda, Tadayuki Takahashi, Claire Chen, Kazuhiro Nakazawa | Summary: We present measurements of the afterglow signatures in NaI(Tl) and CsI(Tl) detector modules as part of the Background and Transient Observer (BTO) mission detector trade-study. BTO is a NASA Student Collaboration Project flying on the […]

Cosmological Consequences of Domain Walls Biased by Quantum Gravity

Posted by dbos January 27, 2025Tokyo

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 January 27, 2025Peking

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 January 25, 2025February 5, 2025Tokyo

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 January 25, 2025February 5, 2025Peking

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 […]

Future Cosmology: New Physics and Opportunity from the China Space Station Telescope (CSST)

Posted by dbos January 25, 2025February 5, 2025Peking

Kavli Affiliate: Hu Zhan | First 5 Authors: Yan Gong, Haitao Miao, Xingchen Zhou, Qi Xiong, Yingxiao Song | Summary: The China Space Station Telescope (CSST) is the next-generation Stage~IV survey telescope. It can simultaneously perform multi-band imaging and slitless spectroscopic wide- and deep-field surveys in ten years and an ultra-deep field (UDF) survey in […]

Theoretical Predictions for the Inner Dark Matter Distribution in the Milky Way Informed by Simulations

Posted by dbos January 24, 2025MIT

Kavli Affiliate: Lina Necib | First 5 Authors: Abdelaziz Hussein, Lina Necib, Manoj Kaplinghat, Stacy Y. Kim, Andrew Wetzel | Summary: We build a theoretical range for the Milky Way’s (MW) inner dark matter (DM) distribution informed by the FIRE-2, Auriga, VINTERGATAN-GM, and TNG50 simulation suites assuming the canonical cold dark matter (CDM) model. The […]
