The X-ray Luminosity - Velocity Dispersion relation in the REFLEX Cluster Survey [PDF]

, 2003
We present an estimate of the bolometric X-ray luminosity - velocity dispersion L_x - sigma_v relation measured from a new, large and homogeneous sample of 171 low redshift, X-ray selected galaxy clusters.

XMM Observations of Abundances in the Intracluster Medium [PDF]

Symposium - International Astronomical Union, 2004
Based on XMM-Newton observations of M 87 and the Centaurus cluster, abundance profiles of various elements of the intracluster medium (ICM) are derived. The abundances of Si and Fe show strong decreasing gradients. In contrast, the O and Mg abundances are about half of the Si abundance at the center.From the gas mass to stellar mass ratio and the ...

Fuzzy‐Based Optimized Cluster Head Selection With Energy Prediction for Unequal Clustering in Wireless Sensor Networks

International Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.
The sensor network consists of several low‐powered electronic sensing devices that are strategically deployed in a predefined area to gather important information. The sensors have low computing capacity, constrained battery energy, and limited storage. Therefore, the sensed data should be communicated to the sink efficiently for further processing. In

Quantifying the Unwinding Due to Ram Pressure Stripping in Simulated Galaxies

Galaxies
Galaxies moving through the gas of the intracluster medium (ICM) experience ram pressure stripping, which can leave behind a gas tail. When a disk galaxy receives the wind edge-on, however, the characteristic signature is not a typical jellyfish tail ...

The Survival of Planetary Nebulae in the Intracluster Medium

, 2005
The stellar population stripped from galaxies in clusters evolve under the extreme conditions imposed by the intracluster (IC) medium. Intracluster stars generally suffer very high systemic velocities, and evolve within a rarefied and extremely hot IC ...

Simulating the interaction of jets with the intracluster medium [PDF]

, 2017
Jets from supermassive black holes in the centres of galaxy clusters are a potential candidate for moderating gas cooling and subsequent star formation through depositing energy in the intra-cluster gas.

Iterative Optimization of the Maximum Directional Distance Function Model for Chinese Airline Transportation Efficiency Evaluations

Journal of Engineering, Volume 2026, Issue 1, 2026.
The maximum directional distance function (MDDF) model has been utilized extensively in diverse fields. However, due to practical constraints such as geographical factors, infrastructure limitations, and network scale, the theoretically improved projection paths derived from this model are often infeasible in real‐world applications.

Are the HI deficient galaxies on the outskirts of Virgo recent arrivals? [PDF]

, 2002
The presence on the Virgo cluster outskirts of spiral galaxies with gas deficiencies as strong as those of the inner galaxies stripped by the intracluster medium has led us to explore the possibility that some of these peripheral objects are not ...

Gas Sloshing in Abell 2204: Constraining the Properties of the Magnetized Intracluster Medium [PDF]

, 2017
The rich galaxy cluster Abell 2204 exhibits edges in its X-ray surface brightness at ∼65 and west and east of its center, respectively. The presence of these edges, which were interpreted as sloshing cold fronts, implies that the intracluster medium (ICM)

EE‐FGO: Energy‐Efficient Fuzzy Grey Wolf Optimization for Cluster Head Selection in WSN

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
A crucial component of the Internet of Things (IoT) is the wireless sensor network (WSN), which comprises numerous sensor nodes detecting various atmospheric variations such as temperature, pressure and humidity. These sensor nodes rely on internal batteries to power their sensors and communicate data with other nodes within the network.
