Blazing trails: Microquasars as head-tail sources and the seeding of magnetized plasma into the ISM

S. Heinz, H. J. Grimm, R. A. Sunyaev +1

We discuss the dynamics of microquasar jets in the interstellar medium, with specific focus on the effects of the X-ray binaries' space velocity with respect to the local Galactic…

The X-ray binary population in M33: II. X-ray spectra and variability

H. -J. Grimm, J. McDowell, A. Zezas +2

In this paper we investigate the X-ray spectra and X-ray spectral variability of compact X-ray sources for 3 Chandra observations of the Local Group galaxy M33. The observations ar…

The X-ray binary population in M33: I. Source list and luminosity function

H. -J. Grimm, J. McDowell, A. Zezas +2

In this paper we present the source list for 3 Chandra observations of the Local Group galaxy M33. The observations are centered on the nucleus and on the star forming region NGC 6…

Statistical properties of the combined emission of a population of discrete sources: astrophysical implications

M. Gilfanov, H-J. Grimm, R. Sunyaev

We study the statistical properties of the combined emission of a population of discrete sources (e.g. X-ray emission of a galaxy due to its X-ray binaries population). Namely, we…

Multiplicity Fluctuations in One- and Two-Dimensional Angular Intervals Compared with Analytic QCD Calculations

B. Buschbeck, F. Mandl

Multiplicity fluctuations in rings around the jet axis and in off-axis cones have been measured by the DELPHI collaboration in annihilations into hadrons at LEP energies.…

The Scale Dependence of the Hadron Multiplicity in Quark and Gluon Jets and a Precise Determination of

DELPHI Collaboration, P. Abreu et al

Data collected at the Z resonance using the DELPHI detector at LEP are used to determine the charged hadron multiplicity in gluon and quark jets as a function of a transverse momen…
