The kinetic power and luminosity of parsec-scale radio jets – an argument for heavy jets
, 1993 We present arguments indicating that radio jets are heavy (i.e. mainly composed of an electron-proton plasma), and that the non-thermal emitting particle distribution has a low-energy cut-off at about 50 MeV.

Monitoring of multi-frequency polarization of gamma-ray bright AGNs
EPJ Web of Conferences, 2013 We started two observing programs with the Korean VLBI Network (KVN) monitoring changes in the flux density and polarization of relativistic jets in gamma-ray bright AGNs simultaneously at 22, 43, 86, 129 GHz.

The jet-disk symbiosis. II. Interpreting the Radio/UV correlations in quasars [PDF]
Astron.Astrophys.298:375,1995, 1994 We investigate the correlation between the accretion disk (UV) luminosity and the radio core emission of a quasar sample. In a radio/$L_{\rm disk}$ plot we find the quasars to be separated into four classes: core dominated quasars (CDQ), lobe dominated quasars (LDQ), radio-intermediate quasars (RIQ) and radio weak quasars.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Advanced Materials, EarlyView.Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Steady jets and transient jets: observational characteristics and models [PDF]
arXiv, 2010 Two types of radio emission are observed from X-ray binaries with jets. They have completely different characteristics and are associated with different kinds of ejections. One kind of emission has a flat or inverted spectrum indicating optically thick self-absorbed synchrotron emission; the second kind of emission corresponds to an optically thin ...
