The hydrodynamics of radio galaxy cocoons by Reynolds, C

“…A full hydrodynamic treatment of radio galaxy expansion is also necessary to interpret correctly the X-ray shells and cavities that, are seen in some sources by ROSAT and Chandra.…”

Jet propulsion of wind ejecta from a major flare in the black hole microquasar SS433 by Blundell, K, Hirst, P

Second-order Fermi acceleration as the origin of the Fermi bubbles by Mertsch, P, Sarkar, S

“…Gamma-ray data from Fermi-LAT show a bi-lobular structure extending up to 50°above and below the Galactic centre, coincident with a possibly related structure in the ROSAT X-ray map which presumably originated in some energy release close to the centre a few million years ago. …”

Models of decelerating relativistic jets in 3C 31 by Laing, R, Bridle, A

“…We use this velocity variation, together with the formulation of conservation of particle number, energy and momentum given by Bicknell (1994), to calculate the physical parameters of the flow. ROSAT observations constrain the external pressure distribution, allowing us to derive unique solutions for pressure, density, Mach number and mass flux as functions of distance from the nucleus. …”

Abell 2256 - Observing a Mpc(3) nonthermal laboratory by Clarke, T, Ensslin, T

“…Evidence of this merger is seen in the X-ray substructure of ROSAT images (Briel et al. 1991). Radio images reveal the complex nature of this cluster: a synchrotron halo, several head-tail radio galaxies, and two extended irregular and sharp-edged regions of diffuse radio emission - so called radio relics (Fig. 1). …”

Detection of a cosmic microwave background decrement toward the z=3.8 quasar pair PC 1643+4631A, B by Jones, M, Saunders, R, Baker, J, Cotter, G, Edge, A, Grainge, K, Haynes, T, Lasenby, A, Pooley, G, Rottgering, H

“…Assuming this to be a Sunyaev-Zeldovich effect due to an intervening cluster, the minimum magnitude of the central temperature decrement is 560 μK. A serendipitous ROSAT observation shows that there is no X-ray-luminous cluster in the direction of the decrement at z < 1. …”

Stellar-mass black hole binaries as ULXs by Rappaport, S, Podsiadlowski, P, Pfahl, E

“…Ultraluminous X-ray sources (ULXs) with L-x > 10(39) ergs s(-1) have been discovered in great numbers in external galaxies with ROSAT, Chandra, and XMM-Newton. The central question regarding this important class of sources is whether they represent an extension in the luminosity function of binary X-ray sources containing neutron stars and stellar-mass black holes (BHs), or a new class of objects, e.g., systems containing intermediate-mass black holes (100-1000 M-circle dot), We have carried out a theoretical study to test whether a large fraction of the ULXs, especially those in galaxies with recent star formation activity, can be explained with binary systems containing stellar-mass black holes. …”

Soft X-ray Excess in the Coma Cluster from a Cosmic Axion Background by Angus, S, Conlon, J, Marsh, M, Powell, A, Witkowski, LT

“…We study the morphology of the soft excess by numerically propagating axions through stochastic, multi-scale magnetic field models that are consistent with observations of Faraday rotation measures from Coma. By comparing to ROSAT observations of the 0.2-0.4 keV soft excess, we find that the overall excess luminosity is easily reproduced for $g_{a\gamma\gamma} \sim 2 \times 10^{-13}$ GeV$^{-1}$. …”
