Molecular gas and star formation in the Tidal Dwarf Galaxy VCC 2062

Lisenfeld, U.; Braine, J.; Duc, P. A.; Boquien, M.; Brinks, E.; Bournaud, F.; Lelli, F.; Charmandaris, V. (2016-06-01)

The physical mechanisms driving star formation (SF) in galaxies are still not fully understood. Tidal dwarf galaxies (TDGs), made of gas ejected during galaxy interactions, seem to be devoid of dark matter and have a ...

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 ...

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 ...

Gas dynamics in tidal dwarf galaxies : disc formation at z=0

Lelli, F.; Duc, P. -A.; Brinks, E.; Bournaud, F.; McGaugh, S. S.; Lisenfeld, U.; Weilbacher, P. M.; Boquien, M.; Revaz, Y.; Braine, J.; Koribalski, B. S.; Belles, P.E. (2015-12)

Tidal dwarf galaxies (TDGs) are recycled objects that form within the collisional debris of interacting/merging galaxies. They are expected to be devoid of non-baryonic dark matter, since they can form only from dissipative ...

Highly perturbed molecular gas in infalling cluster galaxies : the case of CGCG97-079

Scott, T.C.; Usero, A.; Brinks, E.; Bravo-Alfaro, H.; Cortese, L.; Boselli, A.; Argudo-Fernandez, M. (2015-10-11)

We report on CO (J = 2 → 1) mapping with the IRAM 30-m HEtrodyne Receiver Array (HERA) of CGCG 97-079, an irregular galaxy in the merging galaxy cluster Abell 1367 (z = 0.022). We find that ˜80 per cent of the detected CO ...

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 ...

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 ...

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 ...

26Al kinematics: superbubbles following the spiral arms? : Constraints from the statistics of star clusters and HI supershells

Krause, Martin; Diehl, R.; Bagetakos, Y.; Brinks, E.; Burkert, A.; Gerhard, O.; Greiner, J.; Kretschmer, K.; Siegert, T. (2015-06-12)

High energy resolution spectroscopy of the 1.8 MeV radioactive decay line of 26Al with the SPI instrument on board the INTEGRAL satellite has recently revealed that diffuse 26Al has large velocities in comparison to other ...

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. ...
