Unveiling the internal structure of Hercules supercluster
R. Monteiro-Oliveira, D. F. Morell, V. M. Sampaio +2
We have investigated the structure of the Hercules supercluster (SCL160) based on data originally extracted from the Sloan Digital Sky Survey SDSS-DR7. We have traced the mass dist…
Probing Saraswati's heart: evaluating the dynamical state of the massive galaxy cluster A2631 through a comprehensive weak-lensing and dynamical analysis
R. Monteiro-Oliveira, A. C. Soja, A. L. B. Ribeiro +4
In this work, we investigate the dynamical state of the galaxy cluster Abell 2631, a massive structure located at the core of the Saraswati supercluster. To do this, we first solve…
Simulations of the merging galaxy cluster Abell 2034: what determines the level of separation between gas and dark matter
Micheli T. Moura, Rubens E. G. Machado, Rogério Monteiro-Oliveira
Cluster mergers are an important laboratory for studying the behaviour of dark matter (DM) and intracluster gas. There are dissociative collisions that can separate the intracluste…
Simulations of gas sloshing induced by a newly discovered gas poor substructure in galaxy cluster Abell 1644
L. Doubrawa, R. E. G. Machado, T. F. Laganá +3
Collision events lead to peculiar morphologies in the intracluster gas of galaxies clusters. That seems to be the case of Abell 1644, a nearby galaxy cluster, composed of three mai…
Revising the merger scenario of the galaxy cluster Abell 1644: a new gas poor structure discovered by weak gravitational lensing
R. Monteiro-Oliveira, L. Doubrawa, R. E. G. Machado +3
The galaxy cluster Abell 1644 () is known for its remarkable spiral-like X-ray emission. It was previously identified as a bimodal system, comprising the subclusters…
Passive spirals and shock influenced star formation in the merging cluster A3376
Kshitija Kelkar, K. S. Dwarakanath, Bianca M. Poggianti +8
We present a detailed analysis of star formation properties of galaxies in a nearby () young (0.6 Gyr) post-merger cluster system A3376, with a moderate shock fro…
