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…
Investigating Galactic Fountains in M101: Insights from Ionized, UV emissions and Neutral Gas
Aashiya Anitha Shaji, Françoise Combes, Anne-Laure Melchior +1
Spiral galaxy disks are thought to exist in a quasi-stationary state, between fresh gas accretion from cosmic filaments and disk star formation, self-regulated through supernovae f…
Dynamical traction and black hole orbital migration
C. M. Boily, T. L. François, J. Freundlich +3
We investigate the circumstances which allow a black hole to remain put at the galactic centre when the stellar core is anisotropic. We use N-body calculations to study the respons…
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 kiloparsec region of Andromeda. I. Dynamical modelling
Lucie Cros, Françoise Combes, Anne-Laure Melchior +1
The Andromeda galaxy (M31) is the most nearby giant spiral galaxy, an opportunity to study with high resolution dynamical phenomena occurring in nuclear disks and bulges, able to e…
SN 1885A and supernova remnants in the centre of M31 with LOFAR
Deepika Venkattu, Peter Lundqvist, Miguel Pérez Torres +4
We present the first LOFAR image of the centre of M31 at a frequency of 150 MHz. We clearly detect three supernova remnants, which, along with archival VLA data at 3 GHz and other…
