Gamma-Ray Burst Jets and their Radio Observations
Publications Astronomical Society of Australia, 2014 Radio observations play a key role in studying the jets that power GRBs, the most luminous cosmic explosions. They are crucial for determining the GRB jet energy, the external density, and the microphysical parameters of relativistic collisionless shocks,

Discovery of Radio Jets in z ~ 2 Ultraluminous Infrared Galaxies with Deep 9.7 μm Silicate Absorption [PDF]
, 2007 Recent Spitzer observations have revealed a substantial population of z ~ 2 ultraluminous infrared galaxies (ULIRGs) with deep silicate absorption (τ9.7 > 1). This paper reports a 20 cm radio study of such a sample to elucidate their physical nature.

Direct Ink Writing of Conductive Hydrogels
Advanced Functional Materials, EarlyView.This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

New Chandra observations of the jet in 3C273. I. Softer X-ray than radio spectra and the X-ray emission mechanism [PDF]
Astrophys.J.648:900-909,2006, 2006 The jet in 3C273 is a high-power quasar jet with radio, optical and X-ray emission whose size and brightness allow a detailed study of the emission processes acting in it. We present deep Chandra observations of this jet and analyse the spectral properties of the jet emission from radio through X-rays.

The X-ray and radio structure of extragalactic jets
Вісник Астрономічної школи, 2011 The internal structure of jets from active galaxies is explored using the X-ray and radio data. The transverse intensity distributions of X-ray knots in jet are calculated and compared with corresponding intensity distributions for radio knots.

A relativistic model of the radio jets in 3C296 [PDF]
, 2006 We present new, deep 8.5-GHz VLA observations of the nearby, low-luminosity radio galaxy 3C 296 at resolutions from 0.25 to 5.5 arcsec. These show the intensity and polarization structures of the twin radio jets in detail.

Advanced Functional Materials, EarlyView.In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

The compact radio structure of radio-loud narrow line Seyfert 1 galaxies [PDF]
, 2010 We present the compact radio structure of three radio-loud narrow line Seyfert 1 galaxies from VLBA archive data at 2.3, 5 and 8.4 GHz. In RXS J16290+4007, the radio structure is mostly unresolved. The combination of compact radio structure, high brightness temperature and inverted spectrum between simultaneous 2.3 and 8.4 GHz, strongly favors jet ...

HST observations of jets and radio lobes [PDF]
Symposium - International Astronomical Union, 1996 The Hubble Space Telescope has proved to be remarkably useful for discovering and for studying the optical counterparts of radio lobes and radio jets. Since much of the structure seen in the radio is found on subarcsecond scales, it is not surprising that HST, with it's improved resolution relative to ground based observations, would be a major ...
