X-Ray Bright Active Galactic Nuclei in Local Dwarf Galaxies: Insights from eROSITA
Andrea Sacchi, Akos Bogdan, Urmila Chadayammuri +1
Although supermassive black holes (SMBHs) reside in the heart of virtually every massive galaxy, it remains debated whether dwarf galaxies commonly host SMBHs. Because low-mass gal…
Constraints on thermal conductivity in the merging cluster Abell 2146
A. Richard-Laferrière, H. R. Russell, A. C. Fabian +9
The cluster of galaxies Abell 2146 is undergoing a major merger and is an ideal cluster to study ICM physics, as it has a simple geometry with the merger axis in the plane of the s…
Tidal Disruption Event Demographics with the Zwicky Transient Facility: Volumetric Rates, Luminosity Function, and Implications for the Local Black Hole Mass Function
Yuhan Yao, Vikram Ravi, Suvi Gezari +26
We conduct a systematic tidal disruption event (TDE) demographics analysis using the largest sample of optically selected TDEs. A flux-limited, spectroscopically complete sample of…
The structure of cluster merger shocks: turbulent width and the electron heating timescale
H. R. Russell, P. E. J. Nulsen, D. Caprioli +10
We present a new 2 Ms Chandra observation of the cluster merger Abell 2146, which hosts two huge M~2 shock fronts each ~500 kpc across. For the first time, we resolve and measure t…
Turbulent magnetic fields in merging clusters: A case study of Abell 2146
Urmila Chadayammuri, John ZuHone, Paul Nulsen +2
Kelvin-Helmholtz Instabilities (KHI) along contact discontinuities in galaxy clusters have been used to constrain the strength of magnetic fields in galaxy clusters, following the…
Constraining Merging Galaxy Clusters with X-ray and Lensing Simulations and Observations: The case of Abell 2146
Urmila Chadayammuri, John ZuHone, Paul Nulsen +5
Galaxy cluster mergers are a powerful laboratory for testing cosmological and astrophysical models. However, interpreting individual merging clusters depends crucially on their mer…
