Observations of Abell 4059 with Chandra, HST and VLA: unraveling a complex cluster/radio-galaxy interaction
Yun Young Choi, Christopher S. Reynolds, Sebastian Heinz +3
(abridged) We present a detailed reanalysis of the Chandra data for the galaxy cluster Abell 4059 and its central radio galaxy, PKS2354-35. We also present new 1.4GHz and 4.7GHz Cn…
Cosmological Evolution Models for QSO/AGN Luminosity Functions: Effects of Spectrum-Luminosity Correlation and Massive Black Hole Remnants
Yun-Young Choi, Jongmann Yang, Insu Yi
We investigate a large number of cosmological evolution models for QSOs and Active Galactic Nuclei (AGN). We introduce a spectrum-luminosity correlation as a new input parameter an…
Cosmological Luminosity Evolution of QSO/AGN Population
Yunyoung Choi, Jongmann Yang, Insu Yi
We apply the observed optical/X-ray spectral states of the Galactic black hole candidates (GBHCs) to the cosmological QSO luminosity evolution under the assumptions that QSOs and G…
Signatures of Energetic Protons in Hot Accretion Flows: Synchrotron Cooling of Protons in Strongly Magnetized Pulsars
Jongmann Yang, Insu Yi
The existence of hot, two-temperature accretion flows is essential to the recent discussions of the low luminosity, hard X-ray emission from accreting neutron stars and black holes…
