Discovery of a glitch in the accretion-powered pulsar SXP 1062 [PDF]

open access: yes, 2017
We present timing analysis of the accretion powered pulsar SXP 1062, based on the observations of \textit{Swift}, \textit{XMM-Newton} and \textit{Chandra} satellites covering a time span of about 2 years.

Improving transferability between different engineering stages in the development of automated material flow modules [PDF]

open access: yesIEEE Transactions on Automation Science and Engineering 13 (2016) 4, 2022
For improving flexibility and robustness of the engineering of automated production systems (aPS) in case of extending, reducing or modifying parts, several approaches propose an encapsulation and clustering of related functions, e.g. from the electrical, mechanical or software engineering, based on a modular architecture.

Power and linewidth of propagating and localized modes in nanocontact spin-torque oscillators [PDF]

open access: yes, 2012
The integrated power and linewidth of a propagating and a self-localized spin-wave mode excited by spin-polarized current in an obliquely magnetized magnetic nanocontact are studied experimentally ...

30 GHz flux density measurements of the Caltech-Jodrell flat-spectrum sources with OCRA-p [PDF]

open access: yes, 2007
To measure the 30-GHz flux densities of the 293 sources in the Caltech-Jodrell Bank flat-spectrum (CJF) sample. The measurements are part of an ongoing programme to measure the spectral energy distributions of flat spectrum radio sources and to correlate

Timing studies on RXTE observations of SAX J2103.5+4545 [PDF]

open access: yes, 2006
SAX J2103.5+4545 has been continuously monitored for ∼900 d by the Rossi X-ray Timing Explorer (RXTE) since its outburst in 2002 July. Using these observations and previous archival RXTE observations of SAX J2103.5+4545, we refined the binary orbital ...

Evidence of a change in the long-term spin-down rate of the X-ray pulsar 4U 1907+09 [PDF]

open access: yes, 2005
We analysed RXTE archival observations of 4U 1907 +09 between 1996 February 17 and 2002 March 6. The pulse timing analysis showed that the source stayed at almost constant period around 1998 August and then started to spin-down at a rate of (-1.887 ∓ 0 ...

X-ray spectral evolution of Her X-1 in a low state and the following short high state [PDF]

open access: yes, 2005
We analysed spectral variations of ∼8.5-d long Rossi X-ray Timing Explorer (RXTE) monitoring observations of Her X-1 in 2001 December. This set of observations enables, for the first time, frequent continuous monitoring (111 pointings in ∼8.5 d) of the ...
