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 ...
Early-type galaxies in the Antlia cluster: Catalogue and isophotal analysis
(Wiley Blackwell Publishing, Inc, 2018-06)
We present a statistical isophotal analysis of 138 early-type galaxies in the Antlia cluster, located at a distance of ~35 Mpc. The observational material consists of CCD images of four 36 ×36 arcmin2 fields obtained with ...
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 ...
Contribution of the first galaxies to the cosmic far-infrared/sub-millimeter background - I. Mean background level
(Oxford University Press, 2016-11)
We study the contribution of the first galaxies to the far-infrared/sub-millimeter (FIR/sub-mm) extragalactic background light (EBL) by implementing an analytical model for dust emission. We explore different dust models, ...
Ring galaxies in the EAGLE hydrodynamical simulations
(Wiley Blackwell Publishing, Inc, 2018-12)
We study the formation and evolution of ring galaxies in the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations. We use the largest reference model Ref-L100N1504, a cubic cosmological volume of ...
The galaxy size – halo mass scaling relations and clustering properties of central and satellite galaxies
(Oxford University Press, 2021-08)
In this work, we combine size and stellar mass measurements from the Sloan Digital Sky Server (SDSS) with the group finder algorithm of Rodriguez & Merchán in order to determine the stellar and halo mass-size relations of ...
Green valley galaxies as a transition population in different environments
(Wiley Blackwell Publishing, Inc, 2018-02)
We present a comparative analysis of the properties of passive, star-forming and transition (green valley) galaxies in four discrete environments: field, groups, the outskirts and the core of X-ray clusters. We construct ...
Effect of bars on the galaxy properties
(EDP Sciences, 2016-11)
Aims. With the aim of assessing the effects of bars on disk galaxy properties, we present an analysis of different characteristics of spiral galaxies with strong bars, weak bars and without bars. Methods. We identified ...
