Bipolar H{\sc ii} regions produced by cloud/cloud collisions

Anthony Whitworth, Oliver Lomax, Scott Balfour +3

We suggest that Bipolar H{\sc ii} Regions may be the aftermath of collisions between clouds. Such a collision will produce a shock-compressed layer, and a star cluster can then con…

Kinematics and dynamics of the luminous infrared galaxy pair NGC 5257/58 (Arp 240)

I. Fuentes-Carrera, M. Rosado, P. Amram +6

Encounters between galaxies modify their morphology, kinematics, and star formation (SF) history. The relation between these changes and external perturbations is not straightforwa…

CIGALE: a python Code Investigating GALaxy Emission

M. Boquien, D. Burgarella, Y. Roehlly +5

Context. Measuring how the physical properties of galaxies change across cosmic times is essential to understand galaxy formation and evolution. With the advent of numerous ground-…

Dense-gas tracers and carbon isotopes in five 2.5<z<4 lensed dusty star forming galaxies from the SPT SMG sample

M. Bethermin, T. R. Greve, C. De Breuck +15

The origin of the high SFR observed in high-z dusty star-forming galaxies is still unknown. Large fractions of dense molecular gas might provide part of the explanation, but there…

Dark matter stripping in galaxy clusters: a look at the Stellar to Halo Mass relation in the Illustris simulation

Anna Niemiec, Eric Jullo, Carlo Giocoli +2

Satellite galaxies in galaxy clusters represent a significant fraction of the global galaxy population. Because of the unusual dense environment of clusters, their evolution is dri…

Lack of high-mass prestellar cores in the starless MDCs of NGC6334

F. Louvet, S. Neupane, G. Garay +6

Two families of models compete to explain the formation of high-mass stars. The quasi-static models predict the existence of high-mass pre-stellar cores sustained by a high degree…

On the structure and energetics of quasar broad absorption-line outflows

Fred Hamann, Hanna Herbst, Isabelle Paris +1

Quasar accretion-disk outflows might play an important role in galaxy evolution, but they are notoriously difficult to study due to line saturation and blending problems in the Ly-…
