Scalable Computation of Topological Abstractions for Scalar Data

Computer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Molecular hydrogen in galaxies [PDF]

, 1987
This study aims to understand the key role played by molecular hydrogen in the evolution of galaxies, with a view to constraining its radial distribution in the Galaxy and the CO→H(_2) conversion factor α(_20).The star formation rate is shown to be ...

The Galaxy–Halo Connection in Low-mass Halos [PDF]

, 2019
Properties of galaxies vary systematically with the mass of their parent dark matter halos. This basic galaxy–halo connection shows a fair amount of scatter whose origin is not fully understood. Here, we study how differences in the halo assembly history

Survey on Visualization of Information Diffusion over Networks

Computer Graphics Forum, EarlyView.
Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...

The ASTRID Simulation at z = 0: From Massive Black Holes to Large-scale Structure

The Astrophysical Journal
We present the z = 0 results for the cosmological simulation ASTRID . Hosting 2 × 5500 ^3 ≈ 0.33 trillion particles in a box of 370 Mpc per side, ASTRID is one of the largest cosmological hydrodynamic simulations evolved to z = 0. ASTRID features a large

FaceIt: Real‐Time On‐Device Identity‐Preserving Portrait Animation

Computer Graphics Forum, EarlyView.
A real‐time, on‐device algorithm for animating a single portrait image using detailed facial expressions and motions from a driving video achieving visual quality that can outperform even techniques with significantly higher computational overhead. Abstract Recently, significant progress has been made in generating expressive and temporally coherent ...

The clustering of galaxies in hierarchical galaxy formation models [PDF]

, 2010
Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

Strength‐Based Parenting and Relationship Quality in Latine Families Facing Justice System Risk

Family Relations, EarlyView.
ABSTRACT Objective To examine whether parenting practices that are shaped by culturally embedded value systems (responsiveness, autonomy granting, and affective warmth) and familism are associated with parent–adolescent relationship quality among Latine youth, and whether these associations differ by youth justice involvement and gender.

Creating Stellar Populations in Computational Models of Stellar Halos

, 2023
Electronic Thesis or DissertationStellar halos are key to understanding galaxy formation. They extend far away from the disk of the galaxy and preserve its formation history.

The stellar and dark halo mass assembly of galaxies

, 2011
The emerging empirical picture of galaxy stellar mass (Ms) assembly shows that galaxy population buildup proceeds from top to down in Ms. By connecting galaxies to LCDM halos and their histories, individual (average) Ms growth tracks can be inferred. These tracks show that massive galaxies assembled their Ms the earlier the more massive the halo, and ...
