Big Bang nucleosynthesis and the baryonic content of the universe
T. X. Thuan, Y. I. Izotov
A review of the latest measurements of the primordial abundances of the light nuclei D, 3He, 4He and 7Li is given. We discuss in particular the primordial abundance Yp of 4He as me…
Nonthermal Emission in Radio Galaxies from Simulated Relativistic Electron Transport in 3D MHD Flows
I. L. Tregillis, T. W. Jones, Dongsu Ryu
We perform a series of so-called ``synthetic observations'' on a set of 3D MHD jet simulations which explicitly include energy-dependent transport of relativistic electrons, as des…
3D MHD Simulations of Radio Galaxies Including Nonthermal Electron Transport
T. W. Jones, I. L. Tregillis, Dongsu Ryu
We report on an effort to study the connections between dynamics in simulated radio galaxy plasma flows and the properties of nonthermal electron populations carried in those flows…
HST/STIS observations of the HeII Gunn-Peterson effect towards HE 2347-4342
Alain Smette, Sara R. Heap, Gerard M. Williger +3
We present an HST STIS spectrum of the HeII Gunn-Peterson effect towards HE2347-4342. Compared to the previous HST GHRS data obtained by Reimers et al. (1997), the STIS spectrum ha…
LOWL p-mode frequencies and their variation with solar activity
Sebastián J. Jiménez-Reyes, Thierry Corbard, Pere L. Pallé +1
We present an analysis of the frequency shift and the even terms of the frequency splitting coefficients carried out using six years of LOWL data, starting in 1994. The temporal va…
Evidence for Galaxy Formation at High Redshift
T. Shanks, N. Metcalfe, R. Fong +3
We have shown previously that galaxy counts from the UV to the near-IR are well-fitted by simple evolutionary models where the space density of galaxies remains constant with look-…
