Recent Publication(s)

  • "Ionized gas in the starburst core and halo of NGC 1140"

Westmoquette MS, Gallagher JS, de Poitiers L, Monthy Notices of the Royal Astronomical Society 403(4): 1719-1728 Apr 2010.  The data suggests a physical limit to the radius where the broad emission line component is significant, and the authors propose that this limit marks a significant transition point in the development of the galactic outflow, where turbulent motion becomes less dominant. 

  • "Pre-main-sequence turn-on as a chronometer for young clusters: NGC 346 as a benchmark"

Cignoni M, Tosi M, Sabbi E, et al., Astrophysical Journal Letters 712 (1): L63-L68 Mar 2010. We present a novel approach to deriving the age of very young star clusters, by using the Turn-On (TOn).

  • "VLT/FLAMES-ARGUS observations of stellar wind-ISM cloud interactions in NGC 6357 star"

Westmoquette MS, Slavin JD, Smith LJ, et al., Monthly Notices of the Royal Astronomical Society 402 (1): 152-160 Feb 2010. We present optical/near-IR integral field unit observations of a gas pillar in the Galactic H ii region NGC 6357 containing the young open star cluster Pismis 24. These observations have allowed us to examine in detail the gas conditions of the strong wind-clump interactions taking place on its surface

  • "Turbulence and the formation of filaments, loops, and shock fronts in NGC 1275"

Falceta-Goncalves D, Dal Pino EMD, Gallagher JS, et al., Astrophysical Journal Letters 708 (1): L57-L60 Jan 2010. We present 2.5 and three-dimensional magnetohydrodynamical (MHD) simulations of the central region of the cluster in which turbulent energy, possibly triggered by star formation and supernovae (SNe) explosions, is introduced.

  • "NGC 1275: Baryonic cycling in the Perseus cluster of galaxies"

Gallagher JS, Astronomische Nachrichten 330(9-10): 1040-1042 Dec 2009.  This contribution briefly discusses some of the issues raised by the existence of this remarkable ISM system, including its connections to galactic feedback process.
