High-resolution radio imaging of young supernovae
M. A. Perez-Torres, J. M. Marcaide, A. Alberdi +12
The high resolution obtained through the use of VLBI gives an unique opportunity to directly observe the interaction of an expanding radio supernova with its surrounding medium. We…
A Geometric Determination of the Distance to SN 1987A and the LMC
Nino Panagia
Using the definitive reductions of the IUE light curves by Sonneborn et al. (1997) and an extensive set of HST images of SN 1987A we have repeated and improved our original analysi…
The End of the Dark Ages: Probing the Reionization of the Universe with HST and JWST
N. Panagia, M. Stiavelli, S. M. Fall
Limiting the number of model-dependent assumptions to a minimum, we discuss the detectability of the sources responsible for reionization with existing and planned telescopes. We c…
Radio Monitoring of Supernova 2001ig: The First Year
S. D. Ryder, E. Sadler, R. Subrahmanyan +3
Supernova 2001ig in NGC 7424 has been observed with the Australia Telescope Compact Array at ~2 week intervals since its discovery, making this the best-studied Type IIb radio supe…
Primordial Stellar Populations
Nino Panagia
We review the expected properties of the first stellar generations in the Universe. In particular, we consider and discuss the diagnostics, based on the emission from associated HI…
Radio Supernovae and GRB 980425
Kurt W. Weiler, Nino Panagia, Richard A. Sramek +3
Study of radio supernovae (RSNe) over the past 20 years includes two dozen detected objects and more than 100 upper limits. From this work we are able to identify classes of radio…
