Unveiling the Bulge-Disc Structure, AGN Feedback, and Baryon Landscape in a Massive Spiral Galaxy with Mpc-Scale Radio Jets
Joydeep Bagchi, Shankar Ray, Suraj Dhiwar +9
This study delves into the bulge-disc components and stellar mass distribution in the fast-rotating, highly massive spiral galaxy 2MASX~J23453268-0449256, distinguished by extraord…
Exploring chemical enrichment of the intracluster medium with the Line Emission Mapper
François Mernier, Yuanyuan Su, Maxim Markevitch +27
Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxi…
A deep dive: Chandra observations of the NGC 4839 group falling into the Coma cluster
M. S. Mirakhor, S. A. Walker, J. Runge
Cosmological simulations of structure formation predict that galaxy clusters continue to grow and evolve through ongoing mergers with group-scale systems. During these merging even…
Hubble Space Telescope Captures UGC~12591: Bulge/Disc Properties, Star Formation and `Missing Baryons' Census in a Very Massive and Fast Spinning Hybrid Galaxy
Shankar Ray, Joydeep Bagchi, Suraj Dhiwar +4
We present Hubble Space Telescope (HST) observations of the nearby, massive, highly rotating hybrid galaxy UGC~12591, along with observations in UV to FIR bands. HST data in V, I,…
The unusually high dark matter concentration of the galaxy group NGC 1600
J. Runge, S. A. Walker, M. S. Mirakhor
We investigate the properties of the dark matter (DM) halo surrounding the nearby galaxy group NGC 1600. Through the use of deep (252 ks) Chandra observations and 64.3 ks of XMM-Ne…
Probing ultra-diffuse galaxies out to the virial radius of the Coma cluster with XMM-Newton
M. S. Mirakhor, S. A. Walker
We probe the formation scenarios and the active galactic nuclei (AGN) occupation fraction of ultra-diffuse galaxies (UDGs) in the nearby Coma cluster by utilizing XMM-Newton observ…
Exploring the hot gaseous halo around an extremely massive and relativistic jet launching spiral galaxy with XMM-Newton
M. S. Mirakhor, S. A. Walker, J. Bagchi +6
We present a deep XMM-Newton observation of the extremely massive, rapidly rotating, relativistic-jet-launching spiral galaxy 2MASX J23453268-0449256. Diffuse X-ray emission from t…
The gas distribution in the high-redshift cluster MS 1054-0321
M. S. Mirakhor, M. Birkinshaw
We investigate the gas mass distribution in the high redshift cluster MS 1054-0321 using Chandra X-ray and OCRA SZ effect data. We use a superposition of offset -type models to…
