Galaxy distribution and evolution around a sample of 2dF groups
(EDP SCIENCES S A, 2009)
Context. We study galaxy evolution and spatial patterns in the surroundings of a sample of 2dF groups. Aims. Our aim is to find evidence of galaxy evolution and clustering out to 10 times the virial radius of the groups ...
A Widespread, Clumpy Starburst in the Isolated Ongoing Dwarf Galaxy Merger dm1647+21
(IOP PUBLISHING LTD, 2017)
Interactions between pairs of isolated dwarf galaxies provide a critical window into low-mass hierarchical, gas-dominated galaxy assembly and the build-up of stellar mass in low-metallicity systems. We present the first ...
Galaxias satélites de baja luminosidad /
(2009-03)
Se lleva a cabo una caracterización estadística de las poblaciones de galaxias de baja luminosidad asociadas a sistemas de galaxias brillantes y aisladas, pares de galaxias interactuantes, grupos y cúmulos con emisión en ...
Shapley Supercluster Survey: ram-pressure stripping versus tidal interactions in the Shapley supercluster
(2016)
We present two new examples of galaxies undergoing transformation in the Shapley supercluster core. These low-mass galaxies are members of the two clusters SC 1329-313 and SC 1327-312 z similar to 0.049). Integral-field ...
Star formation in the intragroup medium and other diagnostics of the evolutionary stages of compact groups of galaxies
(EDP SCIENCES S A, 2009)
Context. Compact groups of galaxies are entities that have high densities of galaxies and serve as laboratories to study galaxy interactions, intergalactic star formation and galaxy evolution. Aims. The main goal of this ...
Satellites and central galaxies in SDSS: The influence of interactions on their properties
(Wiley Blackwell Publishing, Inc, 2021-02)
We use SDSS-DR14 to construct a sample of galaxy systems consisting of a central object and two satellites. We adopt projected distance and radial velocity difference criteria and impose an isolation criterion to avoid ...
Rotation curve bifurcations as indicators of close recent galaxy encounters
(EDP Sciences, 2008-12)
Rotation curves of interacting galaxies often show that velocities are either rising or falling in the direction of the companion galaxy. We seek to reproduce and analyse these features in the rotation curves of simulated ...
