    • 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 ...

    • The CO-to-H2 Conversion Factor and Dust-to-gas Ratio on Kiloparsec Scales in Nearby Galaxies 

      Sandstrom, K. M.; Leroy, A. K.; Walter, F.; Bolatto, A. D.; Croxall, K. V.; Draine, B. T.; Wilson, C. D.; Wolfire, M.; Calzetti, D.; Kennicutt, R. C.; Aniano, G.; Donovan Meyer, J.; Usero, A.; Bigiel, F.; Brinks, E.; de Blok, W.J.G.; Crocker, A.; Dale, D.; Engelbracht, C.W.; Galametz, M.; Groves, B.; Hunt, L. K.; Koda, J.; Kreckel, K.; Linz, H.; Meidt, S.; Pellegrini, E.; Rix, H-W.; Roussel, H.; Schinnerer, E.; Schruba, A.; Schuster, K-F.; Skibba, R.; van der Laan, T.; Appleton, P.; Armus, L.; Brandl, B.; Gordon, K.; Hinz, J.; Krause, O.; Montiel, E.; Sauvage, M.; Schmiedeke, A.; Smith, J.D.T.; Vigroux, L. (2013-10)

    • A constant molecular gas depletion time in nearby disk galaxies 

      Bigiel, F.; Leroy, A.; Walter, F.; Brinks, E.; de Blok, W.J.G.; Kramer, C.; Rix, H-W.; Schruba, A.; Schuster, K-F.; Usero, A.; Wiesemeyer, H.W. (2011)
      We combine new sensitive, wide-field CO data from the HERACLES survey with ultraviolet and infrared data from GALEX and Spitzer to compare the surface densities of H2, ΣH2, and the recent star formation rate, ΣSFR, over ...

    • Herschel Spectroscopic Observations of Little Things Dwarf Galaxies 

      Cigan, P.; Young, L.; Cormier, D.; Lebouteiller, V.; Madden, S.; Hunter, D.; Brinks, E.; Elmegreen, B.; Schruba, A.; Heesen, V. (2016-01-04)
      We present far-infrared (FIR) spectral line observations of five galaxies from the Little Things sample: DDO 69, DDO 70, DDO 75, DDO 155, and WLM. While most studies of dwarfs focus on bright systems or starbursts due to ...

    • 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 ...

    • Molecular Gas and Star Formation in nearby Disk Galaxies 

      Leroy, A. K.; Walter, F.; Sandstrom, K.; Schruba, A.; Munoz-Mateos, J-C.; Bigiel, F.; Bolatto, A.; Brinks, E.; de Blok, W.J.G.; Meidt, S.; Rix, H-W.; Rosolowsky, E.; Schinnerer, E.; Schuster, K-F.; Usero, A. (2013-08)

    • A molecular star formation law in the atomic-gas-dominated regime in nearby galaxies 

      Schruba, A.; Leroy, A.; Walter, F.; Bigiel, F.; Brinks, E.; de Blok, W.J.G.; Dumas, G.; Kramer, C.; Rosolowsky, E.; Sandstrom, K.; Schuster, K-F.; Usero, Antonio; Weiss, A.; Wiesemeyer, H.W. (2011)
      We use the IRAM HERACLES survey to study CO emission from 33 nearby spiral galaxies down to very low intensities. Using 21 cm line atomic hydrogen (H I) data, mostly from THINGS, we predict the local mean CO velocity based ...
