We present spatially resolved Spitzer Space Telescope imaging of the supergiant shell region of the M81 group dwarf galaxy IC 2574 obtained as part of the Spitzer Infrared Nearby Galaxies Survey. This region harbors one of the best nearby examples of a kinematically distinct H I shell, with an associated remnant stellar cluster; the shell is initiating sequential star formation as it interacts with the surrounding interstellar medium. ...

... We present the results of an interferometric and single-dish study of G24.78+0.08, a region associated with high-mass star formation. ... We suggest that the embedded stars might be too young to have affected the surrounding molecular cloud significantly on a large scale. ... We assess that the (proto)stellar cluster lies at the center of a molecular clump with diameter of ~2 pc: to a good approximation this may be described as a spherically symmetric clump with density profile of the type n~R^(-1.8...

Recent molecular observations indicate supersonic cloud-cloud collision is one of the important modes of O star formation. The O star formation regions studied so far include super star clusters (Westerlund2, NGC3603, RCW38 etc.), mini-starbursts (NGC6334, NGC6357 etc.) HII regions (M42/43, M20 etc.), and Spitzer bubbles (RCW120 etc.) ... Since the collision time scale is short ~10^5 yrs, O star formation is a rapid process with a mass accretion rate higher than 10^-4Mo/yr. ...
