Gridlock Models with the IBM Mega Traffic Simulator: Dependency on Vehicle Acceleration and Road Structure
Bruce G. Elmegreen, Tayfun Gokmen, Biruk Habtemariam
Rush hour and sustained traffic flows in eight cities are studied using the IBM Mega Traffic Simulator to understand the importance of road structures and vehicle acceleration in t…
Challenges and Opportunities in Quantum Optimization
Amira Abbas, Andris Ambainis, Brandon Augustino +43
Recent advances in quantum computers are demonstrating the ability to solve problems at a scale beyond brute force classical simulation. As such, a widespread interest in quantum a…
Neutral atomic and molecular clouds and star formation in the outer Carina arm
Geumsook Park, Bon-Chul Koo, Kee-Tae Kim +1
We present a comprehensive investigation of HI (super)clouds, molecular clouds (MCs), and star formation in the Carina spiral arm of the outer Galaxy. Utilizing HI4PI and CfA CO su…
Universal Upper End of the Stellar Initial Mass Function in the Young and Compact LEGUS clusters
Dooseok Escher Jung, Daniela Calzetti, Matteo Messa +21
We investigate the variation in the upper end of stellar initial mass function (uIMF) in 375 young and compact star clusters in five nearby galaxies within Mpc. All the yo…
Exponential galaxy discs as the quasi-stationary distribution in a Markov chain model simulating stellar scattering
Jian Wu, Curtis Struck, Bruce G. Elmegreen +1
Previous models have shown that stochastic scattering of stars in a two-dimensional galaxy disc can generate a time-independent surface density distribution that is an exponential…
Diverse Molecular Structures Across The Whole Star-Forming Disk of M83: High fidelity Imaging at 40pc Resolution
Jin Koda, Akihiko Hirota, Fumi Egusa +23
We present high-fidelity CO(1-0) imaging of molecular gas across the full star-forming disk of M83, using ALMA's 12m, 7m, and TP arrays and the MIRIAD package. The data have a mass…
