Massive black hole formation in dense stellar environments: Enhanced X-ray detection rates in high velocity dispersion nuclear star clusters

Vivienne F. Baldassare, Nicholas C. Stone, Adi Foord +2

We analyze Chandra X-ray Observatory imaging of 108 galaxies hosting nuclear star clusters (NSCs) to search for signatures of massive black holes (BHs). NSCs are extremely dense st…

A new radio census of neutron star X-ray binaries

J. van den Eijnden, N. Degenaar, T. D. Russell +16

We report new radio observations of a sample of thirty-six neutron star (NS) X-ray binaries, more than doubling the sample in the literature observed at current-day sensitivities.…

Proof of CMB-driven X-ray brightening of high-z radio galaxies

Edmund Hodges-Kluck, Elena Gallo, Gabriele Ghisellini +3

We present a definitive assessment of the role of Inverse Compton scattering of Cosmic Microwave Background photons (IC/CMB) in the context of radio galaxies. Owing to the steep in…

Calibrating X-ray binary luminosity functions via optical reconnaissance I. The case of M83

Qiana Hunt, Elena Gallo, Rupali Chandar +4

Building on recent work by Chandar et al. (2020), we construct X-ray luminosity functions (XLFs) for different classes of X-ray binary (XRB) donors in the nearby star-forming galax…

Observations of the Disk/Jet Coupling of MAXI J1820+070 During its Descent to Quiescence

A. W. Shaw, R. M. Plotkin, J. C. A. Miller-Jones +8

Black hole X-ray binaries in the quiescent state (Eddington ratios typically 10) display softer X-ray spectra (photon indices ) compared to higher-luminosi…

Extended X-ray emission from the z=4.26 radio galaxy 4C 63.20

Kate Napier, Adi Foord, Elena Gallo +5

We report on deep Chandra X-ray Telescope imaging observations of 4C 63.20, one of the few known radio galaxies at z>3.5. The X-ray counterpart is resolved into a core plus two off…
