SZ–X-Ray Surface Brightness Fluctuations in the SPT-XMM Clusters

The Astrophysical Journal
The hot plasma in galaxy clusters, the intracluster medium, is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanisms.

Newcomers Meet the Intracluster Medium in the Coma Cluster [PDF]

, 2004
A main topic at this meeting is how galaxies are affected when they enter for the first time the cluster environment from the outskirts. Most of the times we are forced to infer the environmental effects indirectly, relying on systematic variations of ...

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

Energy Science &Engineering, EarlyView.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Sound waves in the intracluster medium [PDF]

Monthly Notices of the Royal Astronomical Society, 2009
We present an analysis of the behaviour of a perturbed radio cocoon. Comparisons with observations of sound waves detected in the Perseus and Virgo clusters suggest the separations of observed ripples correspond to the natural oscillation frequency of the cocoon.

Quasar Feedback on the Intracluster Medium

The Astrophysical Journal, 2002
Galaxy groups are quite underluminous in X-rays compared to clusters, so the intracluster medium (ICM) has to be considerably underdense in the former. We consider this to be due to substantial energy fed back into the ICM when the baryons in the member galaxies condense into stars ending up in supernovae (SNe) or accrete onto central supermassive ...

Unveiling the Sources of X-Ray Luminosity in DESI Galaxy Groups: Insights from the SRG/eROSITA All-sky Survey

The Astrophysical Journal
We use the first eROSITA all-sky survey to investigate the contributions of active galactic nuclei (AGN) and extended gas to the total X-ray luminosity ( L _X ) of galaxy groups with different halo masses ( M _h ) at different redshifts.

Sustainable Livestock Decisions in a Post‐Conflict Frontier: Evidence From Colombia's Orinoquía

Journal of Agricultural Economics, EarlyView.
ABSTRACT The Orinoquía region is one of Colombia's principal agricultural frontiers and has been shaped by long‐standing armed‐conflict dynamics that continue to influence land governance, producer incentives, and investment decisions. Efforts to promote sustainable cattle production emphasize two key practices: sustainable pasture management ...

oMEGACat. VII. Tracing Interstellar and Intracluster Medium of ω Centauri Using Sodium Absorptions

The Astrophysical Journal
We investigate the foreground interstellar medium along the line of sight and intracluster medium of ω Centauri ( ω Cen) by measuring the equivalent width of Na I D absorptions from MUSE observations. The large line-of-sight velocity difference between ω

Detrending Changes the Temporal Dynamics of a Semantic Fluency Task

Frontiers in Aging Neuroscience, 2016
Objective: To study the dynamics of clustering semantic fluency responses and switching between clusters. Methods: We conducted a cross-sectional study of participants (N=60) in a study of patient reported outcomes who were given the Saint Louis ...
