Intra-cluster patches of baryons in the core of the Fornax cluster
E. Iodice, M. Spavone, M. Cantiello +12
In the core of the Fornax cluster, on the West side of NGC1399, we have detected a previously unknown region of intra-cluster light (ICL). It is made up by several faint ($μ_r \sim…
VEGAS-SSS II: Comparing the globular cluster systems in NGC3115 and NGC1399 using VEGAS and FDS survey data
Michele Cantiello, Raffaele D'Abrusco, Marilena Spavone +15
We analyze the globular cluster (GC) systems in two very different galaxies, N3115 and N1399. With the papers of this series, we aim at highlighting common and different properties…
The Fornax Deep Survey (FDS) with the VST: III. Low Surface Brightness (LSB) dwarfs and Ultra Diffuse Galaxies (UDGs) in the center of the Fornax cluster
A. Venhola, R. Peletier, E. Laurikainen +16
Studies of low surface brightness (LSB) galaxies in nearby clusters have revealed a sub-population of extremely diffuse galaxies with central surface brightness > 24 mag…
Deepest view of AGN X-ray variability with the 7 Ms Chandra Deep Field-South survey
X. C. Zheng, Y. Q. Xue, W. N. Brandt +13
We systematically analyze X-ray variability of active galactic nuclei (AGNs) in the 7~Ms \textit{Chandra} Deep Field-South survey. On the longest timescale ( years), we…
Astrophysical Data Analytics based on Neural Gas Models, using the Classification of Globular Clusters as Playground
Giuseppe Angora, Massimo Brescia, Giuseppe Riccio +3
In Astrophysics, the identification of candidate Globular Clusters through deep, wide-field, single band HST images, is a typical data analytics problem, where methods based on Mac…
The XMM deep survey in the CDF-S. X. X-ray variability of bright sources
S. Falocco, M. Paolillo, A. Comastri +6
We aim to study the variability properties of bright hard X-ray selected Active Galactic Nuclei (AGN) with redshift between 0.3 and 1.6 detected in the Chandra Deep Field South (XM…
