    • Estimating the star formation rate at 1 kpc scales in nearby galaxies. 

      Leroy, Adam K.; Bigiel, Frank; de Blok, W.J.G.; Boissier, Samuel; Bolatto, Alberto; Brinks, E.; Madore, Barry; Munoz-Mateos, Juan-Carlos; Murphy, Eric; Sandstrom, Karin; Schruba, Andreas; Walter, Fabian (2012-07)
      Using combinations of H alpha, ultraviolet (UV), and infrared (IR) emission, we estimate the star formation rate (SFR) surface density, Sigma(SFR), at 1 kpc resolution for 30 disk galaxies that are targets of the IRAM ...

    • High-resolution mass models of dwarf galaxies from LITTLE THINGS 

      Oh, Se-Heon; Hunter, Deidre A.; Brinks, E.; Elmegreen, Bruce G.; Schruba, Andreas; Walter, Fabian; Rupen, Michael P.; Young, Lisa M.; Simpson, Caroline E.; Johnson, Megan; Herrmann, Kimberly A.; Ficut-Vicas, Dana; Cigan, Phil; Heesen, V.; Ashley, Trisha; Zhang, Hong-Xin (2015-06)
      We present high-resolution rotation curves and mass models of 26 dwarf galaxies from LITTLE THINGS. LITTLE THINGS is a high-resolution Very Large Array HI survey for nearby dwarf galaxies in the local volume within 11 Mpc. ...

    • Low CO luminosities in dwarf galaxies 

      Schruba, Andreas; Leroy, Adam K.; Walter, Fabian; Bigiel, Frank; Brinks, E.; de Blok, W.J.G.; Kramer, Carsten; Rosolowsky, Erik; Sandstrom, Karin; Schuster, Karl; Usero, Antonio; Weiss, Axel; Wiesemeyer, Helmut (2012-05-07)
      We present maps of (12)COJ = 2-1 emission covering the entire star-forming disks of 16 nearby dwarf galaxies observed by the IRAM HERACLES survey. The data have 13 '' angular resolution, similar to 250 pc at our average ...

    • Variations in the Star Formation Efficiency of the Dense Molecular Gas across the Disks of Star-Forming Galaxies 

      Usero, Antonio; Leroy, Adam K.; Walter, Fabian; Schruba, Andreas; García-Burillo, Santiago; Sandstrom, Karin; Bigiel, Frank; Brinks, E.; Kramer, Carsten; Rosolowsky, Erik; Schuster, Karl-Friedrich; de Blok, W.J.G. (2015-10)
      We present a new survey of HCN(1-0) emission, a tracer of dense molecular gas, focused on the little-explored regime of normal star-forming galaxy disks. Combining HCN, CO, and infrared (IR) emission, we investigate the ...
