Rotation curve bifurcations as indicators of close recent galaxy encounters
(EDP SCIENCES S A, 2008)
Context. Rotation curves of interacting galaxies often show that velocities are either rising or falling in the direction of the companion galaxy. Aims. We seek to reproduce and analyse these features in the rotation curves ...
On the nature of small galaxy systems
(Wiley Blackwell Publishing, Inc, 2018-12)
We aim at defining homogeneous selection criteria of small galaxy systems in order to build catalogues suitable to compare main properties of pairs, triplets, and groups with four or more members. To this end we use ...
The Hα kinematics of interacting galaxies in 12 compact groups
(Oxford University PressOxford, 2014)
We present new Fabry-Perot observations for a sample of 42 galaxies located in 12 compact
groups of galaxies: HCG 1, HCG 14, HCG 25, HCG 44, HCG 53, HCG 57, HCG 61, HCG
69, HCG 93, VV 304, LGG 455 and Arp 314. From the ...
Galaxy triplets in Sloan Digital Sky Survey Data Release 7: II. A connection with compact groups?
(Oxford University PressOxford, 2013)
We analyse a sample of 71 triplets of luminous galaxies derived from the work of O’Mill et al. We compare the properties of triplets and their members with those of control samples of compact groups, the 10 brightest members ...
The evolution of galaxy metallicity scaling relations in cosmological hydrodynamical simulations
(Oxford University Press, 2015-07-03)
The evolution of the metal content of galaxies and its relations to other global properties [such as total stellar mass (M*), circular velocity, star formation rate (SFR), halo mass, etc.] provides important constraints ...
Optical spectroscopy of young tidal objects around two interacting galaxy pairs
(Wiley Blackwell Publishing, Inc, 2018-10)
We present Gemini Multi-Object Spectrograph spectra of HI-rich tidal features located around the outskirts of two interacting galaxy pairs, NGC 3166/9 and NGC 4725/47. These follow-up observations are part of a multiwavelength ...
