Title: Magellanic Cloud Emission Line Survey 2

Abstract: The Magellanic Clouds provide an excellent site to study the interplay between massive star formation and stellar energy feedback. Star formation activity can be gauged by H(alpha) fluxes, while modes of stellar energy feedback can be diagnosed by H(alpha) images in conjunction with X-ray and radio images. The H(alpha) images from the Magellanic Cloud Emission Line Survey (MCELS), with a 3'' resolution, have been very useful in studies of the interstellar medium. Recent \it Spitzer observations allowed us to identify candidates of young stellar objects (YSO) with masses \ge4 M_\odot. To confirm their nature and to examine conditions in their immediate environment, higher- resolution H(alpha) images were necessary. Therefore, we have undertaken an H(alpha) survey of the LMC using the MOSAIC\sc ii imager on the Blanco 4m telescope. We propose to complete this H(alpha) survey of the LMC and extend it to the SMC, and add [S II] and [O III] observations of regions with strong shocks and active star formation. The total observing time requested is 8 nights. We waive the proprietary period so that this useful survey is immediately available to the public for studies of emission-line objects that can benefit from a resolution better than 1'' (=0.25 pc).
