The tadpole galaxy Kiso 5639: a laboratory for high-energy astrophysics of metal-poor starburst
Abstract
The nearby tadpole galaxy Kiso 5639 contains a starburst head of a 0.1 solar metallicity -- a manifestation of metal-poor gas accretion. We propose a joint Chandra/VLA observing program to study high-energy activity in and around this remarkable dwarf galaxy. We will 1) examine the nature of an ultra-luminous X-ray source; 2) determine the hidden X-ray source population; and 3) quantify the mechanical and chemical feedback of the starburst and its impact on the surrounding medium, as evidenced by an extended X-ray/radio-emitting feature, which most likely represents an energetic blowout from the starburst into the galactic halo. This program will thus provide insights into the end-products of massive stars in low metallicity galaxies, which are common in early universe.
