Disclosing Submillimeter Galaxy Formation: Mergers or Secular Evolution?

The Astrophysical Journal
We analyze the morphology of 125 submillimeter galaxies (SMGs) in the PRIMER-COSMOS field using double Sérsic modeling on JWST NIRCam images across six bands (F150W, F200W, F277W, F356W, F410M, and F444W), with SMGs being classified by the bulge Sérsic ...

Interacting Galaxies with MOND

, 2007
We compare N-body simulations performed in MOND with analogs in Newtonian gravity with dark matter (DM). We have developed a code which solves the Poisson equation in both gravity models. It is a grid solver using adaptive mesh refinement techniques, allowing us to study isolated galaxies as well as interacting galaxies.

Modular training resources for bioimage analysis

Journal of Microscopy, EarlyView.
Abstract Modern microscopy enables us to measure structural and dynamical properties of many biological processes and is therefore an indispensable research tool. However, the amount and complexity of the produced imaging data is steadily increasing.

A Deep Dive into the NGC 741 Galaxy Group: Insights into a Spectacular Head-tail Radio Galaxy from VLA, MeerKAT, uGMRT, and LOFAR

The Astrophysical Journal
We present deep, wideband multifrequency radio observations (144 MHz−8 GHz) of the remarkable galaxy group NGC 741, which yield crucial insights into the interaction between the infalling head-tail radio galaxy (NGC 742) and the main group.

The Role of Flyby Interactions in Shaping Galaxy Evolution

, 2015
Galaxy interactions play a critical role in the growth and evolution of galaxies. While galaxy mergers are known to transform galaxies morphologically and kinematically in a myriad of ways, not all interactions lead to a merger.

Tidal Formation of Dark Matter Deficit Diffuse Galaxy NGC 1052-DF2 by SIDM

The Astrophysical Journal
Observations have revealed a significant dark matter deficit in the ultradiffuse galaxy NGC 1052-DF2 (DF2). It is widely accepted that the formation of this unique galaxy can be attributed to the tidal stripping of its host galaxy, NGC 1052.

The origin of gas stripping of galaxies in group environments

Astronomy & Astrophysics
We investigate how low-mass group environments (Mvir ∼ 1012 − 13 M⊙) influence the gas content of their satellite galaxies with M* > 107 M⊙ using the NEWHORIZON2 simulation.

Mutual Outsourcing in a Vertically Related Market With Strategic Environmental Corporate Social Responsibility

The Manchester School, EarlyView.
ABSTRACT This study considers mutual outsourcing firms in a vertically related market and examines their strategic adoption of environmental corporate social responsibility (ECSR) activities. We demonstrate that ECSR adoption reduces mutual outsourcing firms' profits, resulting in a prisoner's dilemma situation, but enhances welfare regardless of ...
