The Environment of ``E+A'' Galaxies [PDF]

, 1995
The violent star formation history of ``E+A'' galaxies and their detection almost exclusively in distant clusters is frequently used to link them to the ``Butcher-Oemler effect'' and to argue that cluster environment influences galaxy evolution.

Star formation in galaxy interactions and mergers [PDF]

, 2011
This lecture reviews the fundamental physical processes involved in star formation in galaxy interactions and mergers. Interactions and mergers often drive intense starbursts, but the link between interstellar gas physics, large scale interactions, and ...

A Bayesian approach to the semi-analytic model of galaxy formation: methodology [PDF]

, 2010
We believe that a wide range of physical processes conspire to shape the observed galaxy population but we remain unsure of their detailed interactions.

In the wake of dark giants: new signatures of dark matter self-interactions in equal-mass mergers of galaxy clusters [PDF]

, 2016
Author(s): Kim, SY; Peter, AHG; Wittman, D | Abstract: © 2017 The Authors. Merging galaxy clusters have been touted as one of the best probes for constraining selfinteracting darkmatter, but fewsimulations exist to back up this claim.

Galactic PeV Neutrinos

, 2013
IceCube experiment has detected two neutrinos with energies beween 1-10 PeV. They might have originated from Galactic or extragalactic sources of cosmic rays.

Simulations of ram-pressure stripping in galaxy-cluster interactions [PDF]

, 2016
Observationally, the quenching of star-forming galaxies appears to depend both on their mass and environment. The exact cause of the environmental dependence is still poorly understood, yet semi-analytic models (SAMs) of galaxy formation need to ...

The Progenitor of the Peculiar Galaxy NGC 3077

The Astrophysical Journal, 2023
We present a study of the structural properties and metallicity distribution of the nearby peculiar galaxy NGC 3077. Using data from our survey of the M81 Group with the Hyper Suprime-Cam on board the Subaru Telescope, we construct deep color–magnitude ...

SCG0018-4854: a young and dynamic compact group I. Kinematical analysis

, 2009
Compact groups of galaxies are in particular good laboratories for studying galaxy interactions and their effects on the evolution of galaxies due to their high density and low velocity dispersion. SCG0018-4854 is a remarkably high galaxy density and low
