Discovery of Helical Magnetic Fields in AGN, and CME and Ejection of Large-Scale Magnetic Fields from AGN
Autor: L. B. Baath, R. E. Spencer, Han-Shu Chu, Fu-jun Zhang
Publikováno v: Symposium - International Astronomical Union. 214:303-308
Magnetic Fields are the crucial and most important ingredient involved in the processes of various violent activities in Active Galactic Nuclei and other celestial bodies. The generally accepted 2-sided symmetric-jets model of active galactic nuclei

Publikováno v: Astronomy and Astrophysics Supplement Series. 127:505-519
We describe multi-wavelength, simultaneous observations of the RS CVn star, II Pegasi, most of which were obtained during the first three weeks of September 1992. These observations were made using optical and infra-red broad-band photometry, ultravi

Radio Emitting X-Ray Binary Stars
Autor: R. E. Spencer
Publikováno v: International Astronomical Union Colloquium. 158:371-374
Some of the most astrophysically interesting objects are found among the radio-emitting X-ray binary stars (REXRB). The class includes the well-studied objects such as SS 433, Cyg X-3 and Sco X-1. The recent discoveries of relativistic ejection of ra

CSS versus Large Size Sources
Autor: R. Fanti, R. E. Spencer
Publikováno v: Symposium - International Astronomical Union. 175:63-66
A large fraction of the sources in flux density limited radio samples have angular sizes < 2 arcsec (and hence projected linear sizes ≤ 10–15 kpc for H0 = 100 Km/(sec Mpc), and steep (α > 0.5, S∝ v–α) high frequency spectra (Kapahi, 1981; P

Structure in the radio counterpart to the 2004 December 27 giant flare from SGR 1806-20
Autor: R. P. Fender, T. W. B. Muxlow, M. A. Garrett, C. Kouveliotou, B. M. Gaensler, S. T. Garrington, Z. Paragi, V. Tudose, J. C. A. Miller-Jones, R. E. Spencer, R. A. M. Wijers, G. B. Taylor
Publikováno v: Monthly Notices of the Royal Astronomical Society, 367(1), L6-L10
On Dec 27, 2004, the magnetar SGR 1806-20 underwent an enormous outburst resulting in the formation of an expanding, moving, and fading radio source. We report observations of this radio source with the Multi-Element Radio-Linked Interferometer Netwo

Polarimetry of GPS and CSS Sources
Autor: C. Fanti, Richard Schilizzi, R. Fanti, R. E. Spencer, D. J. Saikia, S. T. Garrington, Daniele Dallacasa, A. R. Foley, W. D. Cotton
Publikováno v: Publications Astronomical Society of Australia 20 (2003): 12.

J.; Garrington, S./titolo:Polarimetry of GPS and CSS Sources/doi:/rivista:Publications Astronomical Society of Australia/anno:2003/pagina_da:12/pagina_a:/intervallo_pagine:12/volume:20
The role of radio polarimetry in the understanding of GPS and CSS sources is explored. After an initial discussion of what can be learned from polarimetry, the expectations of a simple evolutionary sequence of GPS/CSO to CSS to FR I/FR II sources are

Modern Cosmological Observations and Problems
Autor: R E Spencer
Publikováno v: European Journal of Physics. 19
This book describes modern cosmology in a novel way compared with most other textbooks. It is framed around observational results rather than the more common approach of being based on theory with occasional support from observations. This makes the
