Feedback and metal enrichment in cosmological SPH simulations I. A model for chemical enrichment
C. Scannapieco, P. B. Tissera, S. D. M. White +1
We discuss a model for treating chemical enrichment by SNII and SNIa explosions in simulations of cosmological structure formation. Our model includes metal-dependent radiative coo…

Giant Meterwave Radio Telescope observations of an M2.8 flare: insights into the initiation of a flare-coronal mass ejection event
Prasad Subramanian, S. Ananthakrishnan, P. Janardhan +3
We present the first observations of a solar flare with the GMRT. An M2.8 flare observed at 1060 MHz with the GMRT on Nov 17 2001 was associated with a prominence eruption observed…
