Molecular gas in a system of two interacting galaxies overlapping on the line-of-sight
Anaëlle Halle, Barbara Mazzilli Ciraulo, Daniel Maschmann +2
Galaxy interactions can disturb gas in galactic discs, compress it, excite it, and enhance star formation. An intriguing system likely consisting of two interacting galaxies overla…
A group of merging galaxies falling onto Abell 2142
Aashiya Anitha Shaji, Anaëlle Hallé, Damir Gasymov +3
Galaxy clusters produce a very hostile environment to galaxies, whose gas gets stripped by ram-pressure, suffer galaxy interactions and witness quenching of their star formation. C…
Central star formation in double-peak gas rich radio galaxies
Daniel Maschmann, Anne-Laure Melchior, Francoise Combes +4
In a recent work, a large sample of double-peak (DP) emission line galaxies have been identified from the SDSS. While the two peaks could represent two kinematic components, they m…
Two interacting galaxies hiding as one, revealed by MaNGA
Barbara Mazzilli Ciraulo, Anne-Laure Melchior, Daniel Maschmann +5
Given their prominent role in galaxy evolution, it is of paramount importance to unveil galaxy interactions and merger events and to investigate the underlying mechanisms. The use…
The effect of fluctuating fuzzy axion haloes on stellar dynamics: a stochastic model
Amr El-Zant, Jonathan Freundlich, Francoise Combes +1
Fuzzy dark matter of ultra-light axions has gained attention, largely in light of the galactic scale problems associated with cold dark matter. But the large de Broglie wavelength,…
On the ridges, undulations & streams in Gaia DR2: Linking the topography of phase-space to the orbital structure of an N-body bar
F. Fragkoudi, D. Katz, W. Trick +7
We explore the origin of phase-space substructures revealed by the second Gaia data release in the disc of the Milky Way, such as the ridges in the - plane, the undulations…
