    • 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 ...

    • Multi-scale clean : a comparison of its performance against classical clean on galaxies using THINGS 

      Rich, J.W.; de Blok, W.J.G.; Cornwell, T.J.; Brinks, E.; Walter, F.; Bagetakos, I.; Kennicutt, R.C. (2008)

    • The nuclear ring in the unbarred galaxy NGC 278: Result of a minor merger 

      Knapen, J.; Whyte, L.F.; de Blok, W.J.G.; van der Hulst, J.M. (2004-08)

    • The star formation efficiency in nearby galaxies : measuring where gas forms stars effectively 

      Leroy, A.; Walter, F.; Brinks, E.; Bigiel, F.; de Blok, W.J.G.; Madore, B.; Thornley, M.D. (2008)
      We measure the star formation efficiency (SFE), the star formation rate (SFR) per unit of gas, in 23 nearby galaxies and compare it with expectations from proposed star formation laws and thresholds.We use Hi maps from The ...

    • Star formation in NGC 5194 (M51a) II: the spatially-resolved star formation law 

      Kennicutt, R.C.; Calzetti, D.; Walter, F.; Helou, G.; Hollenbach, D.; Armus, L.; Bendo, G.; Dale, D.; Draine, B.; Engelbracht, C.; Gordon, K.; Prescott, M.; Regan, M.; Thornley, M.D.; Bot, C.; Brinks, E.; de Blok, W.J.G.; de Mello, D.; Meyer, M.; Moustakas, J.; Murphy, E.; Sheth, K.; Smith, J.D. (2007)

    • The star formation law in nearby galaxies on sub-kpc scales 

      Bigiel, F.; Leroy, A.; Walter, F.; Brinks, E.; de Blok, W.J.G.; Madore, B.; Thornley, M.D. (2008)

    • THINGS: The HI Nearby Galaxy Survey 

      Walter, F.; Brinks, E.; de Blok, W.J.G.; Bigiel, F.; Kennicutt, R.C.; Thornley, M.D.; Leroy, A. (2008)
      We present “The HI Nearby Galaxy Survey (THINGS)”, a high spectral (≤5.2 kms−1) and spatial (~ 6′′) resolution survey of HI emission in 34 nearby galaxies obtained using the NRAO Very Large Array (VLA). The overarching ...

    • 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 ...

    • The VMC survey I. Strategy and first data 

      Cioni, M-R.L.; Clementini, G.; Girardi, L.; Guandalini, R.; Gullieuszik, M.; Miszalski, B.; Moretti, M.I.; Ripepi, V.; Rubele, S.; Bagheri, G.; Bekki, K.; Cross, N.J.G.; de Blok, W.J.G.; de Grijs, R.; Emerson, J.P.; Evans, C.J.; Gibson, B.; Gonzales-Solares, E.; Groenewegen, M.A.T.; Irwin, M.J.; Ivanov, V.D.; Lewis, J.; Marconi, M.; Marquette, J-B.; Mastropietro, C.; Moore, B.; Napiwotzki, R.; Naylor, T.; Oliveira, J.M.; Read, M.; Sutorius, E.; van Loon, J.T.; Wilkinson, M.I.; Wood, P.R.
