Galaxy Merger Candidates in High-redshift Cluster Environments [PDF]
Astrophysical Journal, 2017 We compile a sample of spectroscopically and photometrically selected cluster galaxies from four high-redshift galaxy clusters ( ) from the Spitzer Adaptation of the Red-Sequence Cluster Survey (SpARCS), and a comparison field sample selected from the ...

Вісник Астрономічної школи, 2004 In this work we have simulated the evolution of disk and dwarf galaxies gravitating system, using our viscosity algorithm. We investigated changes in disk galaxy chemical abundance due to minor merger of dwarf galaxy with lower abundance of heavy ...

Isolated Galaxies versus Interacting Pairs with MaNGA
Galaxies, 2015 We present preliminary results of the spectral analysis on the radial distributions of the star formation history in both a galaxy merger and a spiral isolated galaxy observed with MaNGA.

Decoding Galactic Merger Histories
Galaxies, 2017 Galaxy mergers are expected to influence galaxy properties, yet measurements of individual merger histories are lacking. Models predict that merger histories can be measured using stellar halos and that these halos can be quantified using observations of

Observational Constraints on the Merger History of Galaxies since z ≈ 6: Probabilistic Galaxy Pair Counts in the CANDELS Fields [PDF]
Astrophysical Journal, 2019 Galaxy mergers are expected to have a significant role in the mass assembly of galaxies in the early universe, but there are very few observational constraints on the merger history of galaxies at z > 2. We present the first study of galaxy major mergers

Chemie Ingenieur Technik, EarlyView., 2023 Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

The Astrophysical Journal, 2023 The Dragonfly galaxy (MRC 0152-209), the most infrared-luminous radio galaxy at redshift z ∼ 2, is a merger system containing a powerful radio source and large displacements of gas.

CALIFA reveals prolate rotation in massive early-type galaxies: A polar galaxy merger origin? [PDF]
, 2017 We present new evidence for eight early-type galaxies (ETGs) from the CALIFA Survey that show clear rotation around their major photometric axis (“prolate rotation”).

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.

Modelling galaxy merger time-scales and tidal destruction [PDF]
, 2016 We present a model for the dynamical evolution of subhaloes based on an approach combining numerical and analytical methods. Our method is based on tracking subhaloes in an N-body simulation up to the latest epoch that it can be resolved, and applying an
