Direct imaging of sub-parsec binary SMBHs in the central galaxy of the NGC 5044 group
Francesco Ubertosi, Gerrit Schellenberger, Ewan O'Sullivan +7
Binary active galactic nuclei (AGN) consist of two supermassive black holes (SMBHs) hosted in a single galaxy that are simultaneously accreting gas. These systems are key to unders…
The Treble Clef radio phoenix and its old nonthermal filaments
A. Botteon, M. Brienza, K. Rajpurohit +15
By inspecting data from the LOFAR Two-meter Sky Survey (LoTSS), we noticed a peculiar bright and filamentary radio source at low-galactic latitude (). This source,…
AGN Fueling and Radio Jet Evolution in the Galaxy Group NGC 5044 revealed by VLBA HI Absorption and Proper-Motion Radio Observations
Francesco Ubertosi, Ewan O'Sullivan, Gerrit Schellenberger +8
The role of cooling gas in triggering active galactic nucleus (AGN) feedback in the centers of galaxy groups and clusters remains a key open question. NGC 5044, the X-ray brightest…
HST view of NGC 5044: Constraints on Filament Widths, Magnetic Support, Multiphase Structure, and Comparison with Cluster Environments
Prathamesh Tamhane, Ming Sun, William Waldron +12
We present new Hubble Space Telescope (HST) imaging of ionised filaments in the brightest group galaxy NGC 5044. These filaments extend several kiloparsecs and have widths of $\sim…
An X-ray-Emitting Proto-Cluster at Reveals Rapid Structure Growth
Akos Bogdan, Gerrit Schellenberger, Qiong Li +1
Galaxy clusters are the most massive gravitationally bound structures in the universe and serve as tracers of the assembly of large-scale structure. Studying their progenitors, pro…
