Project Details

When massive stars ( >10 x M⨀) form from dense clouds of interstellar gas, their strong radiation field and stellar winds blow bubbles in their ‘birth’ clouds, and the high energy, ionising, radiation they emit heats the surrounding gas creating ‘HII regions’. These HII regions are the bright nebulae that we see in images like below. What we don’t know is the connection be-tween the number of these massive stars and the structure, size and brightness of these interstellar bubbles. Using data from the PHANGS survey you will match catalogues of stellar clusters from the Hubble space telescope with catalogues of HII regions from the European Southern Observatory’s massive MUSE instrument to understand this connection.
