MORPHOLOGY AND MOLECULAR GAS FRACTIONS OF LOCAL LUMINOUS INFRARED GALAXIES AS A FUNCTION OF INFRARED LUMINOSITY AND MERGER STAGE
(IOP PUBLISHING LTD, 2016)
We present a new, detailed analysis of the morphologies and molecular gas fractions (MGFs) for a complete sample of 65 local luminous infrared galaxies from Great Observatories All-Sky Luminous Infrared Galaxies (LIRG) ...
HI aperture synthesis and optical observations of the pair of galaxies NGC 6907 and 6908
(BLACKWELL PUBLISHING, 2008)
NGC 6908, an S0 galaxy situated in the direction of NGC 6907, was only recently recognized as a distinct galaxy, instead of only a part of NGC 6907. We present 21-cm radio synthesis observations obtained with the Giant ...
The global environment of small galaxy systems
(Oxford University Press, 2020-02)
The main goal of this work is to investigate the influence of environment at different scales on the properties of galaxies in systems with a low number of members. To this end we used a catalogue of small galaxy systems ...
The impact of bars and interactions on optically selected AGNs in spiral galaxies
(EDP Sciences, 2018-10)
Aims. With the aim of performing a suitable comparison of the internal process of galactic bars with respect to the external effect of interactions on driving gas toward the inner most region of the galaxies, we explored ...
ALMA Observations Show Major Mergers among the Host Galaxies of Fast-growing, High-redshift, Supermassive Black Holes
(IOP Publishing, 2017)
We present new ALMA band-7 data for a sample of six luminous quasars at z similar or equal to 4.8, powered by fast-growing supermassive black holes (SMBHs) with rather uniform properties: the typical accretion rates and ...
Two formation channels of ultra-compact dwarf galaxies in Hickson compact groups
(EDP SCIENCES S A, 2011)
Context. The formation of ultra-compact dwarf galaxies (UCDs) is believed to be driven by interaction, and UCDs are abundant in the cores of galaxy clusters, environments that mark the end-point of galaxy evolution. Nothing ...
Kinematics of M51-type interacting galaxies
(IOP Publishing, 2016-11)
We present a kinematic catalog for 21 M51-type galaxies. It consists of radial velocity distributions observed with long-slit spectroscopy along different position angles, for both the main and satellite components. We ...
Properties of galaxies with ring structures
(EDP Sciences, 2021-09)
Aims: We present a statistical analysis of different characteristics of ringed spiral galaxies with the aim of assessing the effects of rings on disk galaxy properties. Methods: We built a catalog of ringed galaxies from ...
