Scientific paper

We present the HERA CO-Line Extragalactic Survey (HERACLES) --- an IRAM Large Program that mapped CO 2-1 emission from 47 nearby star-forming galaxies. Building on the THINGS VLA HI survey, Spitzer's SINGS survey, the GALEX Nearby Galaxy Atlas, HERACLES offers the chance to study the star formating interstellar medium in a broad context. We will present the full HERACLES data set for the first time, highlighting a full quarter-square-degree map of the nearby large spiral galaxy M101. We will also describe recent results studying molecular gas in the outer parts of spiral galaxies; relating HI, H2, dust, and star formation on small scales; and measuring the arm-interarm contrast in CO, HI, and SFR tracers.
