Galaxy Zoo: quantifying morphological indicators of galaxy interaction★ [PDF]

Monthly Notices of the Royal Astronomical Society, 2012
We use Galaxy Zoo 2 visual classifications to study the morphological signatures of interaction between similar-mass galaxy pairs in the Sloan Digital Sky Survey. We find that many observable features correlate with projected pair separation; not only obvious indicators of merging, disturbance and tidal tails, but also more regular features, such as ...

A Multiwavelength Study of Active Galactic Nuclei in Post-merger Remnants

The Astrophysical Journal, 2023
We investigate the role of galaxy mergers in triggering active galactic nuclei (AGN) in the nearby universe. Our analysis is based on a sample of 79 post-merger remnant galaxies with deep X-ray observations from Chandra/XMM-Newton capable of detecting a ...

Catching Tidal Dwarf Galaxies at a Later Evolutionary Stage with ALFALFA

The Astronomical Journal, 2023
We present deep optical imaging and photometry of four objects classified as “Almost-Dark” galaxies in the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey because of their gas-rich nature and extremely faint or missing optical emission in ...

Bar-spheroid interaction in galaxies

The Astrophysical Journal, 1992
The secular evolution of barred galaxies is explored using N-body simulation and linear analysis. In particular, we examine the interaction between bars and spheroidal components of galaxies. According to our calculations, this interaction drives secular transfer of angular momentum from bars to spheroids, primarily through resonant coupling.

FAST Reveals New Evidence for M94 as a Merger

The Astrophysical Journal, 2023
We report the first high-sensitivity H i observation toward the spiral galaxy M94 with the Five-hundred-meter Aperture Spherical radio Telescope. From these observations, we discovered that M94 has a very extended H i disk, twice larger than that ...

Galaxy evolution as a function of mass and environment: giant and dwarf galaxies in superclusters and in the field [PDF]

, 2008
It has been known for decades that local galaxies can be broadly divided into two distinct populations (e.g. Hubble 1926, 1936; Morgan 1958; de Vaucouleurs 1961).

Prevalence of galaxy-galaxy interactions in AGN hosts

, 2011
[[abstract]]Studies in optical starlight have failed to reach a consensus on the importance of either galaxy interactions, bars, or nuclear spirals in triggering luminous active galactic nuclei (AGNs).
