Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers
The Astrophysical Journal, 2023 Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.

The Role of AGN in Luminous Infrared Galaxies from the Multiwavelength Perspective
Universe, 2022 Galaxy mergers provide a mechanism for galaxies to effectively funnel gas and materials toward their nuclei and fuel the central starbursts and accretion of supermassive black holes.

SDSS-IV MaNGA: How Galaxy Interactions Influence Active Galactic Nuclei
The Astrophysical Journal, 2023 We present a comparative study of active galactic nuclei (AGN) between galaxy pairs and isolated galaxies with the final data release of the MaNGA integral field spectroscopic survey.

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.

Molecular Gas and Star Formation in Nearby Starburst Galaxy Mergers
The Astrophysical Journal, 2023 We employ the Feedback In Realistic Environments (FIRE-2) physics model to study how the properties of giant molecular clouds (GMCs) evolve during galaxy mergers.

Back to the Green Valley: How to Rejuvenate an S0 Galaxy through Minor Mergers
Galaxies, 2015 About half of the S0 galaxies in the nearby Universe show signatures of recent or ongoing star formation. Whether these S0 galaxies were rejuvenated by the accretion of fresh gas is still controversial.

Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Optical, and X-ray (ICM-SHOX) [PDF]
EPJ Web of ConferencesGalaxy cluster mergers are representative of a wide range of physics, making them an excellent probe of the properties of dark matter and the ionized plasma of the intracluster medium.

Remnants of recent mergers in nearby early-type galaxies and their classification [PDF]
, 2023 We search for signatures of recent galaxy close interactions and mergers in a sample of 202 early-type galaxies in the local universe from the public SDSS Stripe82 deep images ($\mu_r \sim 28.5$ mag arcsec$^{-2}$). Using two different methods to remove galaxies' smooth and symmetric light distribution, we identify and characterize eleven distinct types
