Detection of a relic X-ray jet in Cygnus A

K. C. Steenbrugge, K. M. Blundell, P. Duffy

We present a 200 ks Chandra ACIS-I image of Cygnus A, and discuss a long linear feature seen in its counterlobe. This feature has a non-thermal spectrum and lies on the line connec…

Interacting Jets from Binary Protostars

G. C. Murphy, T. Lery, S. O'Sullivan +3

We investigate potential models that could explain why multiple proto-stellar systems predominantly show single jets. During their formation, stars most frequently produce energeti…

A possible disk mechanism for the 23d QPO in Mkn~501

J. H. Fan, F. M. Rieger, T. X. Hua +7

Optically thin two-temperature accretion flows may be thermally and viscously stable, but acoustically unstable. Here we propose that the O-mode instability of a cooling-dominated…

Multiwavelength Observations of Markarian 421 in March 2001: an Unprecedented View on the X-ray/TeV Correlated Variability

G. Fossati, J. H. Buckley, I. H. Bond +26

(Abridged) We present a detailed analysis of week-long simultaneous observations of the blazar Mrk421 at 2-60 keV X-rays (RXTE) and TeV gamma-rays (Whipple and HEGRA) in 2001. The…

Synchrotron flaring behaviour of CygnusX-3 during the February-March 1994 and September 2001 outbursts

E. J. Lindfors, M. Türler, D. C. Hannikainen +4

Aims: In this paper we study whether the shock-in-jet model, widely used to explain the outbursting behaviour of quasars, can be used to explain the radio flaring behaviour of the…

A Combined Spitzer and Chandra Survey of Young Stellar Objects in the Serpens Cloud Core

E. Winston, S. T. Megeath, S. J. Wolk +7

We present Spitzer and Chandra observations of the nearby (~260 pc) embedded stellar cluster in the Serpens Cloud Core. We observed, using Spitzer's IRAC and MIPS instruments, in s…

Radiative losses and cut-offs of energetic particles at relativistic shocks

Paul Dempsey, Peter Duffy

We investigate the acceleration and simultaneous radiative losses of electrons in the vicinity of relativistic shocks. Particles undergo pitch angle diffusion, gaining energy as th…

Very different X-ray to optical column density ratios in gamma-ray burst afterglows: ionisation in GRB environments

D. Watson, J. Hjorth, J. P. U. Fynbo +4

We compare the HI column densities from Ly-alpha absorption to the metal column densities from X-ray absorption in gamma-ray burst (GRB) afterglows. Eight bursts of seventeen enter…

Gravitational instability of discs with dissipative corona around supermassive black holes

Fazeleh Khajenabi, Mohsen Shadmehri

We study the dynamical structure of a self-gravitating disc with corona around a super-massive black hole. Assuming that the magneto-rotational-instability (MRI) responsible for ge…

Polarisation studies of the prompt gamma-ray emission from GRB 041219a using the Spectrometer aboard INTEGRAL

S. McGlynn, D. J. Clark, A. J. Dean +6

The spectrometer aboard INTEGRAL, SPI, has the capability to detect the signature of polarised emission from a bright gamma-ray source. GRB 041219a is the most intense burst locali…

Very High Energy Observations of Gamma-Ray Burst Locations with the Whipple Telescope

D. Horan, R. W. Atkins, H. M. Badran +56

Gamma-ray burst (GRB) observations at very high energies (VHE, E > 100 GeV) can impose tight constraints on some GRB emission models. Many GRB afterglow models predict a VHE compon…
