A new Chandra look at the globular cluster NGC 6540 and its peculiar X-ray flaring source
A. Sacchi, S. Mereghetti, R. Di Stefano +4
We report the results of a deep ( ks) Chandra exposure of the globular cluster NGC 6540, obtained by combining three observations carried out in 2023-2024 to investigate…
The intracluster light analysis of the most evolved systems of galaxies: fossil groups
Nícolas O. L. de Oliveira, Yolanda Jiménez-Teja, Renato A. Dupke +7
We present the analysis of the intracluster light (ICL) in three fossil groups (FG), RXJ085640.72+055347.36, RX J1136+0713, and RX J1410+4145, at z ~ 0.1. We used two optical broad…
SDSS-C4 3028: The Nearest Blue Galaxy Cluster Devoid of an Intracluster Medium
Shweta Jain, Yuanyuan Su, Andra Stroe +9
SDSS-C4 3028 is a galaxy cluster at , notable for its unusually high fraction of star-forming galaxies with 19 star-forming and 11 quiescent spectroscopically-confirmed me…
Fifteen Years of M31* X-ray Variability and Flares
Stephen DiKerby, Shuo Zhang, Jimmy Irwin
We append an additional fifteen years (2009-2024) to the Chandra X-ray light curve of M31*, the supermassive black hole at the center of M31, the Andromeda galaxy. Extending and ex…
Low-Mass Galaxy Interactions Trigger Black Hole Activity
Marko Mićić, Jimmy A. Irwin, Preethi Nair +3
The existence of high- over-massive supermassive black holes represents a major conundrum in our understanding of black hole evolution. In this paper, we probe from the observat…
SDSS J125417.98+274004.6: An X-ray Detected Minor Merger Dual AGN
Marko Mićić, Brenna N. Wells, Olivia J. Holmes +1
In this paper, we present the discovery of a dual AGN in a 11:1 minor merger between the galaxy SDSS J125417.98+274004.6 and its unnamed dwarf satellite. We calculated stella…
Astro2020 Science White Paper: A Unification of the Micro and Macro Physics in the Intracluster Medium of Nearby Clusters
Y. Su, R. Kraft, E. Roediger +9
Clusters of galaxies are the most massive virialized structures in the Universe. The microphysical properties of the intracluster plasma can affect dynamical processes over an enor…
Assessing the reliability of Friends-of-Friends groups on the future Javalambre Physics of the Accelerating Universe Astrophysical Survey
A. Zandivarez, E. Díaz-Giménez, C. Mendes de Oliveira +6
We have performed a detailed analysis of the ability of the friends-of-friends algorithm in identifying real galaxy systems in deep surveys such as the future Javalambre Physics of…
