FULLY COMPRESSIVE TIDES IN GALAXY MERGERS [PDF]
The Astrophysical Journal, 2009 The disruptive effect of galactic tides is a textbook example of gravitational dynamics. However, depending on the shape of the potential, tides can also become fully compressive. When that is the case, they might trigger or strengthen the formation of galactic substructures (star clusters, tidal dwarf galaxies), instead of destroying them.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Massive Black Hole Binaries: Dynamical Evolution and Observational Signatures
Advances in Astronomy, 2012 The study of the dynamical evolution of massive black hole pairs in mergers is crucial in the context of a hierarchical galaxy formation scenario. The timescales for the formation and the coalescence of black hole binaries are still poorly constrained ...

Mergers and galaxy evolution [PDF]
, 2007 Galaxy merging is the late time manifestation of the galaxy formation process and likely significantly effects z < 1 galaxies. A "maximum reasonable rate" model for merging finds a ,~ 2 mag K band increase in the luminosities of dwarf galaxies so that they contribute significantly to the faint counts, with spirals and ellipticals being far less ...

Observing Galaxy Mergers at the Epoch of Reionization
The Astrophysical Journal, 2018 Abstract The galaxies with photometric redshifts observed in a close angular proximity might be either projection coincidences, strongly lensed images of the same galaxy, or separate galaxies that are in a stage of merging. We search for the groups of galaxies in the Hubble Ultra Deep Field (HUDF09) in z ∼ 7 and z ∼ 8 drop-out samples ...

On the Use of Galaxy Catalogs in Gravitational-wave Parameter Estimation
The Astrophysical JournalA major challenge in gravitational-wave (GW) multimessenger astrophysics is the imprecise localization of GW compact binary mergers. We investigate the use of a method to include galaxy catalog information in performing parameter estimation of these ...

The History of Galaxy Mergers in IllustrisTNG
UniverseThe process of galaxy evolution over cosmic time is not yet fully understood, since there is a debate on the impact of galaxy collisions on the star formation and metallicity.

PHOTOMETRIC DECOMPOSITION OF MERGERS IN DISK GALAXIES [PDF]
The Astrophysical Journal, 2014 Several observational studies and numerical simulations suggest that mergers must contribute to the evolution of galaxies; however, the role that they play is not yet fully understood. In this paper we study a sample of 52 double nucleus disk galaxies that are considered as candidates for a minor merger event.

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Increased awareness of sustainable food production and vegan, vegetarian and flexitarian diets are driving the growth in dairy substitutes, particularly plant‐based yoghurts. To understand consumer perception or mind‐set and facilitate adoption of plant‐based yoghurt products, a multi‐phase study using both qualitative and ...
