Corona, Jet, and Relativistic Line Models for Suzaku/RXTE/Chandra-HETG Observations of the Cygnus X-1 Hard State
Michael A. Nowak, Manfred Hanke, Sarah N. Trowbridge +7
Using Suzaku and the Rossi X-ray Timing Explorer, we have conducted a series of four simultaneous observations of the galactic black hole candidate Cyg X-1 in what were historicall…
Dynamical Black Hole Masses of BL Lac Objects from the Sloan Digital Sky Survey
Richard M. Plotkin, Sera Markoff, Scott C. Trager +1
We measure black hole masses for 71 BL Lac objects from the Sloan Digital Sky Survey with redshifts out to z~0.4. We perform spectral decompositions of their nuclei from their host…
The Jet in the Galactic Center: An Ideal Laboratory for Magnetohydrodynamics and General Relativity
Heino Falcke, Sera Markoff, Geoffrey C. Bower +3
In this paper we review and discuss some of the intriguing properties of the Galactic Center supermassive black hole candidate Sgr A*. Of all possible black hole sources, the event…
Jets at lowest mass accretion rates
Dipankar Maitra, Andrew Cantrell, Sera Markoff +3
We present results of recent observations and theoretical modeling of data from black holes accreting at very low luminosities (L/L_Edd ~ 10^{-8}). We discuss our newly developed t…
Investigating accretion disk - radio jet coupling across the stellar mass scale
James C. A. Miller-Jones, Gregory R. Sivakoff, Diego Altamirano +13
Relationships between the X-ray and radio behavior of black hole X-ray binaries during outbursts have established a fundamental coupling between the accretion disks and radio jets…
Determining the optimal locations for shock acceleration in magnetohydrodynamical jets
Peter Polko, David L. Meier, Sera Markoff
Observations of relativistic jets from black holes systems suggest that particle acceleration often occurs at fixed locations within the flow. These sites could be associated with…
