Illuminating Dark Matter Halo Density Profiles Without Subhaloes

Kavli Affiliate: Risa Wechsler | First 5 Authors: Catherine E. Fielder, Yao-Yuan Mao, Andrew R. Zentner, Jeffrey A. Newman, Hao-Yi Wu | Summary: Cold dark matter haloes consist of a relatively smooth dark matter component as well as a system of bound subhaloes. It is the prevailing practice to include all halo mass, including mass […]

On the Chemical Abundance of HR 8799 and the Planet c

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Ji Wang, Jason Wang, Bo Ma, Jeffrey Chilcote, Steve Ertel | Summary: Comparing chemical abundances of a planet and the host star reveals the origin and formation path. Stellar abundance is measured with high-resolution spectroscopy. Planet abundance, on the other hand, is usually inferred from low-resolution data. […]

Dust Reverberation Mapping in Distant Quasars from Optical and Mid-Infrared Imaging Surveys

Kavli Affiliate: Joshua Frieman | First 5 Authors: Qian Yang, Yue Shen, Xin Liu, Michel Aguena, James Annis | Summary: The size of the dust torus in Active Galactic Nuclei (AGN) and their high-luminosity counterparts, quasars, can be inferred from the time delay between UV/optical accretion disk continuum variability and the response in the mid-infrared […]

Impact of internal-delensing biases on searches for primordial B-modes of CMB polarisation

Kavli Affiliate: Anthony Challinor | First 5 Authors: Antón Baleato Lizancos, Anthony Challinor, Julien Carron, , | Summary: Searches for the imprint of primordial gravitational waves in degree-scale CMB $B$-mode polarisation data must account for significant contamination from gravitational lensing. Fortunately, the lensing effects can be partially removed by combining high-resolution $E$-mode measurements with an […]

Robust and Accurate Authorship Attribution via Program Normalization

Kavli Affiliate: Ke Wang | First 5 Authors: Yizhen Wang, Mohannad Alhanahnah, Ke Wang, Mihai Christodorescu, Somesh Jha | Summary: Source code attribution approaches have achieved remarkable accuracy thanks to the rapid advances in deep learning. However, recent studies shed light on their vulnerability to adversarial attacks. In particular, they can be easily deceived by […]

Correlating surface energy with adsorption energy by means of intrinsic characteristics of substrates

Kavli Affiliate: Li Xin Li | First 5 Authors: Bo Li, Xin Li, Wang Gao, Qing Jiang, | Summary: Surface energy is fundamental in controlling surface properties and surface-driven processes like heterogeneous catalysis, as adsorption energy is. It is thus crucial to establish an effective scheme to determine surface energy and its relation with adsorption […]

Topics on global analysis of manifolds and representation theory of reductive groups

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: Geometric symmetry induces symmetries of function spaces, and the latter yields a clue to global analysis via representation theory. In this note we summarize recent developments on the general theory about how geometric conditions affect representation theoretic properties on function […]

A hidden symmetry of a branching law

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, Birgit Speh, , , | Summary: We consider branching laws for the restriction of some irreducible unitary representations $Pi$ of $G=O(p,q)$ to its subgroup $H=O(p-1,q)$. In Kobayashi (arXiv:1907.07994), the irreducible subrepresentations of $O(p-1,q)$ in the restriction of the unitary $Pi|_{O(p-1,q) }$ are determined. By considering […]

Survey of Gravitationally lensed Objects in HSC Imaging (SuGOHI) — VII. Discovery and Confirmation of Three Strongly Lensed Quasars

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Anton T. Jaelani, Cristian E. Rusu, Issha Kayo, Anupreeta More, Alessandro Sonnenfeld | Summary: We present spectroscopic confirmation of three new two-image gravitationally lensed quasars, compiled from existing strong lens and X-ray catalogs. Images of HSC J091843.27$-$022007.5 show a red galaxy with two blue point sources […]

On window theorem for categorical Donaldson-Thomas theories on local surfaces and its applications

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: In this paper, we prove a window theorem for categorical Donaldson-Thomas theories on local surfaces as an analogue of window theorem for GIT quotient stacks. We give two applications of our main result. The first one is a proof of […]
