Where are compact groups in the local Universe? [PDF]
, 2015 The purpose of this work is to perform a statistical analysis of the location of compact groups in the Universe from observational and semi-analytical points of view.

Hierarchical inference of the relationship between Concentration and Mass in Galaxy Groups and Clusters [PDF]
, 2017 Mass is a fundamental property of galaxy groups and clusters. In theory weak gravitational lensing will enable an approximately unbiased measurement of mass, but parametric methods for extracting cluster masses from data require the additional knowledge ...

The Origin of Intergalactic Light in Compact Groups of Galaxies
Universe, 2021 We investigate the origin of intergalactic light (IGL) in close groups of galaxies. IGL is hypothesized to be the byproduct of interaction and merger within compact groups.

Constraints on the Optical Depth of Galaxy Groups and Clusters [PDF]
, 2016 Future data from galaxy redshift surveys, combined with high-resolutions maps of the cosmic microwave background, will enable measurements of the pairwise kinematic Sunyaev–Zel’dovich (kSZ) signal with unprecedented statistical significance.

On the common nature of dark matter and dark energy: Galaxy groups [PDF]
The European Physical Journal Plus, 2017 .It is shown that the cosmological constant links the roots both of General Relativity and Newtonian gravity via the general function satisfying Newton’s theorem according to which the gravitating sphere acts as a point mass situated in its center.

Targeted decrease of portal hepatic pressure gradient improves ascites control after TIPS
Hepatology, EarlyView., 2022 The river diagram demonstrates that after transjugular intrahepatic portosystemic shunt insertion (TIPS) the majority of patients without ascites and 50% of the patients with ascites detectable at ultrasound, show the best response in the long term follow‐up.

Halo ellipticity of GAMA galaxy groups from KiDS weak lensing [PDF]
, 2016 We constrain the average halo ellipticity of ~2 600 galaxy groups from the Galaxy And Mass Assembly (GAMA) survey, using the weak gravitational lensing signal measured from the overlapping Kilo Degree Survey (KiDS).
