Posted by dbos Chicago

Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Michael S. Calzadilla, Michael McDonald, Bradford A. Benson, Lindsey E. Bleem, Judith H. Croston | Summary: We present a multi-wavelength study of the brightest cluster galaxies (BCGs) in a sample of the 95 most massive galaxy clusters selected from South Pole Telescope (SPT) Sunyaev-Zeldovich (SZ) survey. […]

Yang-Mills instantons as the end point of black hole evaporation

Posted by dbos Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Pisin Chen, Xiao Yan Chew, Misao Sasaki, Dong-han Yeom, | Summary: Non-perturbative contributions of the Euclidean path integral are important to understand the information loss paradox. In this paper, we revisit the Yang-Mills instantons in the Einstein-Yang-Mills theory. There exists a globally regular solution that is known […]

Planets Across Space and Time (PAST). V. The evolution of hot Jupiters revealed by the age distribution of their host stars

Posted by dbos Peking

Kavli Affiliate: Subo Dong | First 5 Authors: Di-Chang Chen, Ji-Wei Xie, Ji-Lin Zhou, Subo Dong, Jia-Yi Yang | Summary: The unexpected discovery of hot Jupiters challenged the classical theory of planet formation inspired by our solar system. Until now, the origin and evolution of hot Jupiters are still uncertain. Determining their age distribution and […]

Updating the first CHIME/FRB catalog of fast radio bursts with baseband data

Posted by dbos MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, :, Mandana Amiri, Bridget C. Andersen, Shion Andrew | Summary: In 2021, a catalog of 536 fast radio bursts (FRBs) detected with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope was released by the CHIME/FRB Collaboration. This large collection of bursts, observed […]

Reviving MeV-GeV Indirect Detection with Inelastic Dark Matter

Posted by dbos Chicago

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Asher Berlin, Gordan Krnjaic, Elena Pinetti, , | Summary: Thermal relic dark matter below $sim 10 text{GeV}$ is excluded by cosmic microwave background data if its annihilation to visible particles is unsuppressed near the epoch of recombination. Usual model-building measures to avoid this bound involve kinematically suppressing […]

Weak Limit of $W^{1,2}$ Homeomorphisms in $mathbb{R}^3$ Can Have Any Degree

Posted by dbos UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Ondřej Bouchala, Stanislav Hencl, Zheng Zhu, , | Summary: In this paper for every $kinmathbb{Z}$ we construct a sequence of weakly converging homeomorphisms $h_mcolon B(0,10)tomathbb{R}^3$, $h_mrightharpoonup h$ in $W^{1,2}(B(0,10))$, such that $h_m(x)=x$ on $partial B(0,10)$ and for every $rin left(tfrac5{16},tfrac{7}{16}right)$ the degree of $h$ with respect to […]

Flow Morphology of a Supersonic Gravitating Sphere

Posted by dbos UCSB

Kavli Affiliate: Lars Bildsten | First 5 Authors: Logan J. Prust, Lars Bildsten, , , | Summary: Stars and planets move supersonically in a gaseous medium during planetary engulfment, stellar interactions and within protoplanetary disks. For a nearly uniform medium, the relevant parameters are the Mach number and the size of the body, $R$, relative […]

C-Silicon-based metasurfaces for aperture-robust spectrometer/imaging with angle integration

Posted by dbos Berkeley

Kavli Affiliate: Ting Xu | First 5 Authors: Weizhu Xu, Qingbin Fan, Peicheng Lin, Jiarong Wang, Hao Hu | Summary: Compared with conventional grating-based spectrometers, reconstructive spectrometers based on spectrally engineered filtering have the advantage of miniaturization because of the less demand for dispersive optics and free propagation space. However, available reconstructive spectrometers fail to […]

Further Development of Event-Based Analysis of X-ray Polarization Data

Posted by dbos MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Herman L. Marshall, , , , | Summary: An event-based maximum likelihood method for handling X-ray polarimetry data is extended to include the effects of background and nonuniform sampling of the possible position angle space. While nonuniform sampling in position angle space generally introduces cross terms […]
