Massive galaxy mergers have distinctive global H I profiles

, 2022
The global 21 cm H i emission-line profile of a galaxy encodes valuable information on the spatial distribution and kinematics of the neutral atomic gas.

Formation of a Polar Ring Galaxy in a Galaxy Merger [PDF]

The Astrophysical Journal, 1998
We numerically investigate stellar and gas dynamics in star-forming and dissipative galaxy mergers between two disk galaxies with specific orbital configurations. We find that violent relaxation combined with gaseous dissipation in galaxy merging transforms two disk galaxies into one S0 galaxy with polar-rings: Both the central S0-like host and the ...

Origin and Evolution of Dust-obscured Galaxies in Galaxy Mergers

The Astrophysical Journal, 2022
Abstract Dust-obscured galaxies (DOGs), which are observationally characterized as faint in the optical and bright in the infrared, are the final stage of galaxy mergers and are essential objects in the evolution of galaxies and active galactic nuclei (AGNs).

Studying SMBH – Galaxy Coevolution in Mergers

, 2021
Galaxy mergers are key events in the process of galaxy evolution. It is thought that merger events drive gas and dust towards the centers of merging galaxies. This should lead to increased star formation and SMBH growth.

Do galaxy mergers prefer under-dense environments? [PDF]

Context. Galaxy mergers play a crucial role in galaxy evolution. However, the correlation between mergers and the local environment of galaxies is not fully understood.Aims.

Secondary evolution of galaxies investigated by N-body simulations [PDF]

, 2008
In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

Deep learning for galaxy mergers in the galaxy main sequence [PDF]

Proceedings of the International Astronomical Union, 2019
AbstractStarburst galaxies are often found to be the result of galaxy mergers. As a result, galaxy mergers are often believed to lie above the galaxy main sequence: the tight correlation between stellar mass and star formation rate. Here, we aim to test this claim.Deep learning techniques are applied to images from the Sloan Digital Sky Survey to ...

A semi-analytic model comparison - gas cooling and galaxy mergers [PDF]

, 2010
We use stripped-down versions of three semi-analytic galaxy formation models to study the influence of different assumptions about gas cooling and galaxy mergers.
