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.

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Galaxy Mergers Moulding The Cgm

, 2017
Galaxies are surrounded by sizeable gas reservoirs which host a significant amount of metals: the circum-galactic medium (CGM). The CGM acts as a mediator between the galaxy and the extra-galactic medium. However, our understanding of how galaxy mergers, a major evolutionary transformation, impact the CGM remains deficient.

Galaxy evolution in the post-merger regime. II -- Post-merger quenching peaks within 500 Myr of coalescence

The Open Journal of Astrophysics
Mechanisms for quenching star formation in galaxies remain hotly debated, with galaxy mergers an oft-proposed pathway. In Ellison et al. (2022) we tested this scenario by quantifying the fraction of recently and rapidly quenched post-starbursts (PSBs) in

Evolution in the black hole mass-bulge mass relation: a theoretical perspective

, 2005
We explore the growth of super-massive black holes and host galaxy bulges in the galaxy population using the Millennium Run LCDM simulation coupled with a model of galaxy formation.

Cluster Core Heating from Merging Subclusters

, 2009
Though feedback from central active galactic nuclei provides an attractive solution to the problem of overcooling in galaxy cluster cores, another possible source of heating may come from ``sloshing'' of the cluster core gas initiated by mergers.

The Origins of Gas Accreted by Supermassive Black Holes: The Importance of Recycled Gas

The Astrophysical Journal
We investigate the fueling mechanisms of supermassive black holes (SMBHs) by analyzing 10 zoom-in cosmological simulations of massive galaxies, with stellar masses 10 ^11–12 M _⊙ and SMBH masses 10 ^8.9–9.7 M _⊙ at z = 0, featuring various major and ...

Tumor desialylation surpasses anti‐PD‐L1 checkpoint therapy in restoring anti‐tumor immunity in a murine model for colorectal cancer

International Journal of Cancer, EarlyView.
What's New? Our research highlights how tumor sialylation affects tumor growth and reshapes the immune tumor microenvironment in colorectal cancer. We demonstrate for the first time that complete removal of sialic acids from colorectal tumor cells elicits a robust anti‐tumor immune response, but does not enhance anti‐PD‐L1 blockade efficacy.

McFACTS III: Compact Binary Mergers from Active Galactic Nucleus Disks over an Entire Synthetic Universe

The Astrophysical Journal
The active galactic nucleus (AGN) channel for the formation of binary black hole (BBH) mergers has been previously studied as a potential formation channel for the merging compact binaries observed by the LIGO–Virgo–KAGRA (LVK) scientific collaboration ...
