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 ...

Galaxy mergers in a fractal cosmology
The European Physical Journal CAbstract This work discusses the influence of galaxy mergers in the evolution of a parabolic Lemaître–Tolman–Bondi (LTB) cosmology with simultaneous big bang endowed with two consecutive single fractal galaxy distributions systems possessing fractal dimension D.

JWST Reveals a Possible z ∼ 11 Galaxy Merger in Triply Lensed MACS0647–JD [PDF]
Astrophysical Journal Letters, 2022 MACS0647–JD is a triply lensed z ∼ 11 galaxy originally discovered with the Hubble Space Telescope. The three lensed images are magnified by factors of ∼8, 5, and 2 to AB mag 25.1, 25.6, and 26.6 at 3.5 μm. The brightest is over a magnitude brighter than

Clumpy Star Formation and AGN Activity in the Dwarf–Dwarf Galaxy Merger Mrk 709 [PDF]
Astrophysical Journal, 2021 Nearby, low-metallicity dwarf starburst galaxies hosting active galactic nuclei (AGNs) offer the best local analogs to study the early evolution of galaxies and their supermassive black holes (BHs).

The combined and respective roles of imaging and stellar kinematics in identifying galaxy merger remnants [PDF]
, 2022 One of the central challenges to establishing the role of mergers in galaxy evolution is the selection of pure and complete merger samples in observations.

Galaxy Merger Rates up to z ∼ 3 Using a Bayesian Deep Learning Model: A Major-merger Classifier Using IllustrisTNG Simulation Data [PDF]
Astrophysical Journal, 2020 Merging is potentially the dominant process in galaxy formation, yet there is still debate about its history over cosmic time. To address this, we classify major mergers and measure galaxy merger rates up to z ∼ 3 in all five CANDELS fields (UDS, EGS ...

Emerge: Empirical predictions of galaxy merger rates since z ∼ 6 [PDF]
, 2020 We explore the galaxy-galaxy merger rate with the empirical model for galaxy formation, \textsc{emerge}. On average, we find that between $2$ per cent and $20$ per cent of massive galaxies ($\log_{10}(m_{*}/M_{\odot}) \geq 10.3$) will experience a major ...

The Astrophysical Journal, 2023 Pairs of galaxies hosting active galactic nuclei (AGNs) are powerful probes of merger-driven supermassive black hole (SMBH) growth as they can resolve individual AGNs and trace mergers over a large range of physical separations.
