A 1D fluid model of the Centaurus A jet
Wykes, Sarka; Snios, Bradford T.; Nulsen, Paul E. J.; Kraft, Ralph P.; Birkinshaw, Mark; Hardcastle, Martin J.; Worrall, Diana M.; McDonald, Iain; Rejkuba, Marina; Jones, Thomas W.; Stark, David J.; Forman, William R.; Meyer, Eileen T.; Jones, Christine (2019-05-01)We implement a steady, one-dimensional flow model for the X-ray jet of Centaurus A in which entrainment of stellar mass loss is the primary cause of dissipation. Using over 260 ks of new and archival Chandra/ACIS data, we ... -
Variability and Proper Motion of X-ray Knots in the Jet of Centaurus A
Snios, Bradford; Wykes, Sarka; Nulsen, Paul E. J.; Kraft, Ralph P.; Meyer, Eileen T.; Birkinshaw, Mark; Worrall, Diana M.; Hardcastle, Martin J.; Roediger, Elke; Forman, William R.; Jones, Christine (2019-02-05)We report results from Chandra observations analyzed for evidence of variability and proper motion in the X-ray jet of Centaurus A. Using data spanning 15 yr, collective proper motion of 11.3 ± 3.3 mas yr -1 , or 0.68 ± ...
