Kavli Affiliate: George Ricker | First 5 Authors: Rahul Jayaraman, Donald W. Kurtz, Gerald Handler, Saul Rappaport, George Ricker | Summary: We present two new rapidly oscillating Ap (roAp) stars, TIC 198781841 and TIC 229960986, discovered in TESS photometric data. The periodogram of TIC 198781841 has a large peak at 166.506 d$^{-1}$ (1.93 mHz), with […]
Kavli Affiliate: Steven Allen, Lindsey E. Bleem, Bradford Benson, Adam B. Mantz | First 5 Authors: Adam B. Mantz, Steven W. Allen, Rebecca E. A. Canning, Lucie Baumont, Bradford Benson | Summary: We present updated cosmological constraints from measurements of the gas mass fractions ($f_{gas}$) of massive, dynamically relaxed galaxy clusters. Our new data set […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Gourav Khullar, Matthew B. Bayliss, Michael D. Gladders, Keunho J. Kim, Michael S Calzadilla | Summary: Using stellar population synthesis models to infer star formation histories (SFHs), we analyse photometry and spectroscopy of a large sample of quiescent galaxies which are members of Sunyaev-Zel’dovich (SZ)-selected galaxy […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Mykola Telychko, Keian Noori, Hillol Biswas, Dikshant Dulal, Pin Lyu | Summary: We report an atomically-precise integration of individual nitrogen (N) dopant as an in-plane artificial nucleus in a graphene device by atomic implantation to probe its gate-tunable quantum states and correlation effects. The N dopant […]
Kavli Affiliate: Jing Wang | First 5 Authors: Yang Li, Jing Wang, Hai-Qing Lin, Lei Shao, | Summary: Bio-compatible Au nanoparticles exhibit great advantages in the application of biomedical researches, such as bio-sensing, medical diagnosis, and cancer therapy. Bio-molecules can even be manipulated by laser tweezers with the optically trapped Au nanoparticles as handles. In […]
Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Eve Schoen, Calvin Leung, Kiyoshi Masui, Daniele Michilli, Pragya Chawla | Summary: We describe a pipeline to measure scintillation in fast radio bursts (FRBs) detected by CHIME/FRB in the 400-800 MHz band by analyzing the frequency structure of the FRB’s spectrum. We use the pipeline to measure […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: David I. Dunsky, Anish Ghoshal, Hitoshi Murayama, Yuki Sakakihara, Graham White | Summary: The symmetry breaking of grand unified gauge groups in the early Universe often leaves behind relic topological defects such as cosmic strings, domain walls, or monopoles. For some symmetry breaking chains, hybrid defects can […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Xuheng Ding, Simon Birrer, Tommaso Treu, John D. Silverman, | Summary: Galight is a Python-based open-source package that can be used to perform two-dimensional model fitting of optical and near-infrared images to characterize the light distribution of galaxies with components including a disk, bulge, bar, and […]
Kavli Affiliate: Risa Wechsler | First 5 Authors: Yunchong Wang, Shude Mao, Mark Vogelsberger, Volker Springel, Lars Hernquist | Summary: Early-type galaxies (ETGs) possess total radial density profiles that are largely described by singular isothermal spheres, which can lead to non-Gaussian line-of-sight velocity dispersion (LOSVD) under anisotropic stellar orbits. However, recent observations of local ETGs […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Pablo Villanueva-Domingo, Francisco Villaescusa-Navarro, Daniel Anglés-Alcázar, Shy Genel, Federico Marinacci | Summary: Understanding the halo-galaxy connection is fundamental in order to improve our knowledge on the nature and properties of dark matter. In this work we build a model that infers the mass of a halo […]
