    • Carbon monoxide in clouds at low metallicity in the dwarf irregular galaxy WLM 

      Elmegreen, B.G.; Rubio, M.; Hunter, D. A.; Verdugo, C.; Brinks, E.; Schruba, A. (2013-03-27)
      Carbon monoxide (CO) is the primary tracer for interstellar clouds where stars form, but it has never been detected in galaxies in which the oxygen abundance relative to hydrogen is less than 20 per cent of that of the ...

    • Deep radio continuum imaging of the dwarf irregular galaxy IC 10: tracing star formation and magnetic fields 

      Heesen, V.; Rau, U.; Rupen, M. P.; Brinks, E.; Hunter, D. A. (2011-09-20)
      We exploit the vastly increased sensitivity of the Expanded Very Large Array to study the radio continuum and polarization properties of the post-starburst, dwarf irregular galaxy IC 10 at 6 cm, at a linear resolution of ...

    • Little Things 

      Hunter, D. A.; Ficut-Vicas, D.; Ashley, T.; Brinks, E.; Cigan, P.; Elmegreen, B. G.; Heesen, V.; Herrmann, K. A.; Johnson, M.; Oh, S.H.; Rupen, M. P.; Schruba, A.; Simpson, C.E.; Walter, F.; Westpfahl, D. J.; Young, L. M.; Zhang, H.-X. (2012-11)
      We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The H I Nearby Galaxy Survey), which is aimed at determining what drives star formation in dwarf galaxies. This is a multi-wavelength survey of 37 ...

    • The non-thermal superbubble in IC 10 : the generation of cosmic ray electrons caught in the act 

      Heesen, V.; Brinks, E.; Krause, Martin; Harwood, J.J.; Rau, U.; Rupen, M. P.; Hunter, D. A.; Chyzy, K.T.; Kitchener, Ben (2015-02-01)
      Superbubbles are crucial for stellar feedback, with supposedly high (of the order of 10 per cent) thermalization rates. We combined multiband radio continuum observations from the Very Large Array (VLA) with Effelsberg ...

    • The Stellar and Gas Kinematics of the LITTLE THINGS Dwarf Irregular Galaxy NGC 1569 

      Johnson, M.; Hunter, D. A.; Oh, S.H.; Zhang, H.-X.; Elmegreen, B.; Brinks, E.; Tollerud, E.; Herrmann, K. (2012-11)
      In order to understand the formation and evolution of Magellanic-type dwarf irregular (dIm) galaxies, one needs to understand their three-dimensional structure. We present measurements of the stellar velocity dispersion ...
