    • ALMA CO Clouds and Young Star Complexes in the Interacting Galaxies IC 2163 and NGC 2207 

      Elmegreen, Debra Meloy; Elmegreen, Bruce G.; Kaufman, Michele; Brinks, Elias; Struck, Curtis; Bournaud, Frederic; Sheth, Kartik; Juneau, Stephanie (2017-05-22)
      ALMA observations of CO(1-0) emission in the interacting galaxies IC 2163 and NGC 2207 are used to determine the properties of molecular clouds and their association with star-forming regions observed with the Hubble Space ...

    • Dense cloud cores revealed by CO in the low metallicity dwarf galaxy WLM 

      Rubio, Monica; Elmegreen, Bruce G.; Hunter, Deidre A.; Brinks, E.; Cortés, Juan R.; Cigan, Phil (2015-09-10)
      Understanding stellar birth requires observations of the clouds in which they form. These clouds are dense and self-gravitating, and in all existing observations they are molecular, with H2 the dominant species and carbon ...

    • Herschel Photometric Observations of LITTLE THINGS Dwarf Galaxies 

      Cigan, Phil; Young, Lisa M.; Gomez, Haley L.; Madden, Suzanne C.; Vis, Pieter De; Hunter, Deidre A.; Elmegreen, Bruce G.; Brinks, Elias (2021-08-02)
      We present here far-infrared photometry of galaxies in a sample that is relatively unexplored at these wavelengths: low-metallicity dwarf galaxies with moderate star formation rates. Four dwarf irregular galaxies from the ...

    • High star formation rates in turbulent atomic-dominated gas in the interacting galaxies IC 2163 and NGC 2207 

      Elmegreen, Bruce G.; Kaufman, Michele; Bournaud, Frederic; Elmegreen, Debra Meloy; Struck, Curtis; Brinks, E.; Juneau, Stephanie (2016-05-20)
      CO observations of the interacting galaxies IC 2163 and NGC 2207 are combined with HI, Halpha and 24 microns to study the star formation rate (SFR) surface density as a function of the gas surface density. More than half ...

    • 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. ...

    • Massive star cluster formation and evolution in tidal dwarf galaxies 

      Fensch, Jeremy; Duc, Pierre-Alain; Boquien, Mederic; Elmegreen, Debra M.; Elmegreen, Bruce G.; Bournaud, Frederic; Brinks, Elias; Grijs, Richard de; Lelli, Federico; Renaud, Florent; Weilbacher, Peter M. (2019-07-12)
      The formation of globular clusters remains an open debate. Dwarf starburst galaxies are efficient at forming young massive clusters with similar masses as globular clusters and may hold the key to understanding their ...

    • Ocular Shock Front in the Colliding Galaxy IC 2163 

      Kaufman, Michele; Elmegreen, Bruce G.; Struck, Curtis; Elmegreen, Debra Meloy; Bournaud, Frederic; Brinks, Elias; Juneau, Stephanie; Sheth, Kartik (2016-11-04)
      ALMA observations in the CO 1 - 0 line of the interacting galaxies IC 2163 and NGC 2207 at 2" x 1.5" resolution reveal how the encounter drives gas to pile up in narrow, ~ 1 kpc wide, "eyelids" in IC 2163. IC 2163 and NGC ...

    • Outflow from Outer-arm Starburst in a Grazing Collision between Galaxies 

      Kaufman, Michele; Elmegreen, Bruce G.; Andersen, Morten; Elmegreen, Debra Meloy; Struck, Curtis; Bournaud, Frederic; Brinks, Elias; McGarry, James C. (2020-04)
      New ALMA CO, HCO+, and 100 GHz continuum observations and Gemini NIFS K-band spectra are combined with previous radio to X-ray data to study Feature i, a highly luminous starburst clump on an outer arm of the interacting ...

    • VII Zw 403: H I structure in a blue compact dwarf galaxy 

      Simpson, Caroline E.; Hunter, Deidre A.; Nordgren, Tyler E.; Brinks, E.; Elmegreen, Bruce G.; Ashley, Trisha; Lynds, Roger; McIntyre, Vince J.; O'Neil, Earl J.; Ostlin, Goran; Westpfahl, David J.; Wilcots, Eric M. (2011-09)
      We present optical (UBVJ), ultraviolet (FUV, NUV), and high-resolution atomic hydrogen (H I) observations of the nearby blue compact dwarf (BCD), VII Zw 403. We find that VII Zw 403 has a relatively high H I mass-to-light ...

    • A Warp in Progress : H I and Radio Continuum Observations of the Spiral NGC 3145 

      Kaufman, Michele; Brinks, E.; Struck, Curtis; Elmegreen, Bruce G.; Elmegreen, Debra M. (2015-09)
      We present VLA H I and 6 cm radio continuum observations of the spiral NGC 3145 and H I observations of its two companions, NGC 3143 and PGC 029578. In optical images NGC 3145 has stellar arms that appear to cross, forming ...
