We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their...

In this article, dedicated to the memory of Lesser Blum, we develop a theory for the physical clusters which were introduced some time ago in our group (J. Chem Phys. 116, 1097–1108, 2002). The physical cluster definit...

The giant elliptical galaxy NGC1316 is the brightest galaxy in the Fornax cluster, and displays a number of morphological features that might be interpreted as an intermediate age merger remanent (~3 Gyr). Based on the i...

This article aims to contribute to the evaluation of development policies for female farmers based on their beneficiaries' attitudes. For this, it was conducted a survey in the Metropolitan Region of Santiago, Chile, to ...

Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way. In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important probes of an on-going merger. Aims. Our main goal...

Purpose – This paper aims to analyse the impact of clusters on development and growth at the firm and regional level in Latin America (LA). The past 20 years have witnessed an acceleration of cluster initiatives, assum...

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters represent the most massive star-forming environment that is dominated by the feedback fro...

ABSTRACT Consonant clusters occur both in Portuguese and English. However, clusters are more productive in English than in Portuguese and there are sequences which are only found in English.This study focuses on the cont...

Properties of massive galaxy clusters, such as mass abundance and concentration, are sensitive to cosmology, making cluster statistics a powerful tool for cosmological studies. However, favoring a more simplified, spheri...

Abstract Background Leptospirosis is a zoonotic disease of concern and an investigation of recent spatio‐temporal trends of leptospirosis in dogs in the United States is needed. Leptospira PCR testing has become increa...

By means of zoom-in hydrodynamic simulations, we quantify the amount of neutral hydrogen (H i) hosted by groups and clusters of galaxies. Our simulations, which are based on an improved formulation of smoothed particle h...

Only four globular cluster planetary nebulae (GCPN) are known so far in the Milky Way. About 50 new globular clusters have been recently discovered toward the Galactic bulge. We present a search for planetary nebulae wit...

The earliest stages of star formation occur enshrouded in dust and are not observable in the optical. Here we leverage the extraordinary new high-resolution infrared imaging from JWST to begin the study of dust-embedded ...

The article demonstrates that since the early 2000s, the EU’s cluster policy has transformed into one of the key instruments for achieving the strategic goals of the European Union. It has been established that the cre...

We analyse the radial pressure profiles, the intracluster medium (ICM) clumping factor and the Sunyaev-Zel'dovich (SZ) scaling relations of a sample of simulated galaxy clusters and groups identified in a set of hydrodyn...

Segundo as descrições fonológicas e as normas ortográficas do português, todas as sequências Obstruinte+Líquida constituiriam, nesta língua, sequências tautossilábicas (Ataques ramificados), sendo heterossiláb...

Abstract Background Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating multisystem disease characterized by heterogeneous symptom patterns. Previous work suggested that specific symptoms tend t...

During the last decades, much effort has been devoted to explain the discrepancy between the amount of intracluster medium (ICM) estimated from stellar evolution theories and that emerging from observations in globular c...

Road traffic crashes are among the leading causes of death and injury worldwide. While urban planning and design are known to influence road safety, it is not clear how features of the built environment contribute to tra...

The characteristics of the young stellar population in the nearby irregular galaxy NGC 2366 were investigated. In particular, we focused our attention on its hierarchical clustering distributions and the properties of th...

Aims. We aim to investigate the feasibility of accurately determining the helium-to-metal enrichment ratio ΔY/ΔZ for open clusters using Gaia DR3 photometry. Methods. To test the reliability of this calibration, we per...

Abstract There is a growing body of research on disease clusters in multimorbidity. Here we systematically review clustering methodologies and perform a meta-analysis of disease cluster stability across the literature, s...

This article contains an analysis of the relationships between companies belonging to clusters in the Świętokrzyskie scientific community. These relationships are the subject of research, both in terms of geographic re...

Understanding the nature of the interaction between the lead(II) ion, Pb2+, and water molecules is crucial to describe the stability and chemical behaviour of structures formed during solvation, as well as theconditions ...
