Self-Similarity of $k$-Nearest Neighbor Distributions in Scale-Free Simulations

Kavli Affiliate: Tom Abel | First 5 Authors: Lehman H. Garrison, Tom Abel, Daniel J. Eisenstein, , | Summary: We use the $k$-nearest neighbor probability distribution function ($k$NN-PDF, Banerjee & Abel 2021) to assess convergence in a scale-free $N$-body simulation. Compared to our previous two-point analysis, the $k$NN-PDF allows us to quantify our results in […]

Subsurface Carbon-Induced Local Charge of Copper for On-Surface Displacement Reaction

Kavli Affiliate: Zhuo Li | First 5 Authors: Shaoshan Wang, Pengcheng Ding, Zhuo Li, Cristina Mattioli, Wenlong E | Summary: Transition metal carbides have sparked unprecedented enthusiasm as high-performance catalysts in recent years. Still, the catalytic properties of copper (Cu) carbide remain unexplored. By introducing subsurface carbon (C) to Cu(111), displacement reaction of proton in […]

On-Surface Decarboxylation Coupling Facilitated by Lock-to-Unlock Variation of Molecules upon the Reaction

Kavli Affiliate: Zhuo Li | First 5 Authors: Shaoshan Wang, Zhuo Li, Pengcheng Ding, Cristina Mattioli, Wujun Huang | Summary: On-surface synthesis (OSS) involving relatively high energy barriers remains challenging due to a typical dilemma: firm molecular anchor is required to prevent molecular desorption upon the reaction, whereas sufficient lateral mobility is crucial for subsequent […]

Approximating Density Probability Distribution Functions Across Cosmologies

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Huanqing Chen, Nickolay Y. Gnedin, Philip Mansfield, , | Summary: Using a suite of self-similar cosmological simulations, we measure the probability distribution functions (PDFs) of real-space density, redshift-space density, and their geometric mean. We find that the real-space density PDF is well-described by a function of […]

The stellar mass versus stellar metallicity relation of star-forming galaxies at $1.6le zle3.0$ and implications for the evolution of the $α$-enhancement

Kavli Affiliate: John D. Silverman | First 5 Authors: Daichi Kashino, Simon J. Lilly, Alvio Renzini, Emanuele Daddi, Giovanni Zamorani | Summary: We measure the relationship between stellar mass and stellar metallicity, the stellar mass–metallicity relation (MZR), for 1336 star-forming galaxies at $1.6le zle3.0$ (<z>=2.2) using rest-frame far-ultraviolet spectra from the zCOSMOS-deep survey. High signal-to-noise […]

Searching for Axion-Like Particles from Core-Collapse Supernovae with Fermi LAT’s Low Energy Technique

Kavli Affiliate: Nicola Omodei | First 5 Authors: Milena Crnogorčević, Regina Caputo, Manuel Meyer, Nicola Omodei, Michael Gustafsson | Summary: Light axion-like particles (ALPs) are expected to be abundantly produced in core-collapse supernovae (CCSNe), resulting in a $sim$10-second long burst of ALPs. These particles subsequently undergo conversion into gamma-rays in external magnetic fields to produce […]

Evaluating and Enhancing Candidate Clocking Systems for CHIME/FRB VLBI Outriggers

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Savannah Cary, Juan Mena-Parra, Calvin Leung, Kiyoshi Masui, J. F. Kaczmarek | Summary: As the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has become the leading instrument for detecting Fast Radio Bursts (FRBs), CHIME/FRB Outriggers will use very-long-baseline interferometry (VLBI) to localize FRBs with milliarcsecond precision. The CHIME […]

Directional Detection of Light Dark Matter in Superconductors

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Yonit Hochberg, Eric David Kramer, Noah Kurinsky, Benjamin V. Lehmann, | Summary: Superconducting detectors have been proposed as outstanding targets for the direct detection of light dark matter scattering at masses as low as a keV. We study the prospects for directional detection of dark matter in […]

The Atacama Cosmology Telescope: Constraints on Pre-Recombination Early Dark Energy

Kavli Affiliate: David N. Spergel | First 5 Authors: J. Colin Hill, Erminia Calabrese, Simone Aiola, Nicholas Battaglia, Boris Bolliet | Summary: The early dark energy (EDE) scenario aims to increase the value of the Hubble constant ($H_0$) inferred from cosmic microwave background (CMB) data over that found in $Lambda$CDM, via the introduction of a […]
