XRISM Observations of A1795: Evidence for Low Turbulence and Resonant Scattering

open access: yesThe Astrophysical Journal Letters
We present high-resolution X-ray spectroscopic observations of the cool-core galaxy cluster A1795 obtained with XRISM/Resolve. The cluster was observed with two deep pointings: a 225 ks central exposure and a 113 ks northern exposure, extending to a ...

Scalable Computation of Topological Abstractions for Scalar Data

open access: yesComputer 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 ...

Survey on Visualization of Information Diffusion over Networks

open access: yesComputer 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 ...

Early Type Galaxies And Reliable Galaxy Cluster Selection [PDF]

open access: yes, 2010
In an era of precision cosmology, clusters of galaxies are the natural consequences under the hierarchical scenario, within which clusters directly encapsulate the history of structure formation.

On the Particle Acceleration Mechanisms in a Double Radio Relic Galaxy Cluster, Abell 1240

open access: yesThe Astrophysical Journal
We present a 368 ks deep Chandra observation of Abell 1240, a binary merging galaxy cluster at a redshift of 0.195 with two brightest cluster galaxies that may have passed each other 0.3 Gyr ago.

MORPHOLOGICAL TYPES OF 254 RICH PF GALAXY CLUSTERS

open access: yesOdessa Astronomical Publications, 2014
We determined the morphological types for 254 rich galaxy clusters from the PF Catalogue of Galaxy Clusters and Groups. The data set contains the PF galaxy clusters, which have no ACO coinciding ones.

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

open access: yesComputer 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 ...

Cluster Properties as a Function of Dynamical State in the DESI Legacy × UNIONS Surveys

open access: yesThe Astrophysical Journal
We investigate how the dynamical state of galaxy clusters influences their galaxy populations and mass distributions. Using photometrically selected clusters from the DESI Legacy Imaging Survey crossmatched with the UNIONS galaxy shear catalog, we ...

COMPARISON OF OPTICAL AND X-RAY MASS ESTIMATES OF THE CHANDRA GALAXY CLUSTERS AT Z < 0.1

open access: yesOdessa Astronomical Publications, 2013
We used the optical data taken from SDSS DR7 galaxy and group catalog to determine the optical mass of 37 nearer Chandra galaxy clusters for comparison with the X-ray mass estimates.
