Black holes undergoing accretion are thought to emit the bulk of their power in the X-ray band by releasing the gravitational potential energy of the infalling matter. At the same time, they are capable of producing highly collimated jets of energy and particles flowing out of the system with relativistic velocities. Here we show that the 10-solar-mass(More)
This paper proposes a design concept for a tangible interface for collaborative performances that incorporates two social factors present during performance, the individual creation and adaptation of technology and the sharing of it within a community. These factors are identified using the example of a laptop ensemble and then applied to three existing(More)
today Abstract We propose that relativistic Galactic jets like those observed in GRS 1915+105 and GRO J1655-40 may produce a small but measurable contribution to the cosmic ray (CR) spectrum. If these jets contain cold protons and heavy ions (as in the case of SS433), it is plausible that this component will consist of a narrow spectral feature, with a mean(More)
We present a comprehensive synthesis model for the AGN evolution and the growth of super-massive black hole in the Universe. We assume that black holes accrete in just three distinct physical states, or " modes " : at low Eddington ratio, only a radiatively inefficient, kinetically dominated mode is allowed (LK); at high Eddington ratio, instead, AGN may(More)
Table of content: We report on a hybrid sheet-based manufacturing approach for organic electrochemical transistors comprising printing and a self-aligning laser ablation step. Abstract We report on a hybrid manufacturing approach for organic electrochemical transistors (OECTs) on flexible substrates. The technology is based on conventional and digital(More)
We present Chandra observations of the galaxy cluster A4059. We find strong evidence that the FR-I radio galaxy PKS 2354–35 at the center of A4059 is inflating cavities with radii ∼ 20 kpc in the intracluster medium (ICM), similar to the situation seen in Perseus A and Hydra A. We also find evidence for interaction between the ICM and PKS 2354–35 on small(More)
NASA's Chandra X-ray Observatory continues to provide an unparalleled means for exploring the high-energy universe. With its half-arcsecond angular resolution, Chandra studies have deepened our understanding of galaxy clusters, active galactic nuclei, galaxies, supernova remnants, neutron stars, black holes, and solar system objects. As we look beyond(More)
