Chemical evolution during gas-rich galaxy interactions [PDF]

, 2011
We perform and analyse a set of galaxy interactions performed by using a self-consistent chemo-hydrodynamical model which includes star formation, supernova (SN) feedback and chemical evolution.

The nongravitational interactions of dark matter in colliding galaxy clusters [PDF]

Science, 2015
Uncloaking the influence of the invisible actor The idea of dark matter enjoys popular support, but two major concerns persist: the so-called Standard Model excludes it, and it cannot be directly detected by any telescope.

Galaxy pairs in the Sloan Digital Sky Survey - XII: The fuelling mechanism of low excitation radio-loud AGN [PDF]

, 2015
We investigate whether the fuelling of low excitation radio galaxies (LERGs) is linked to major galaxy interactions. Our study utilizes a sample of 10,800 spectroscopic galaxy pairs and 97 post-mergers selected from the Sloan Digital Sky Survey with ...

Are luminous radio-loud active galactic nuclei triggered by galaxy interactions? [PDF]

, 2011
We present the results of a comparison between the optical morphologies of a complete sample of 46 southern 2 Jy radio galaxies at intermediate redshifts (0.05

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 ...

Scale Interactions and Galaxy Evolution [PDF]

Astrophysics and Space Science, 2003
To understand galaxies and their evolution, it is necessary to describe how the different scales interact: how the microscopic physics, such as star formation, or the large scale physics, such as galaxy interactions may modify the galaxy global shapes.

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 ...

Galaxy And Mass Assembly (GAMA): growing up in a bad neighbourhood - how do low-mass galaxies become passive? [PDF]

, 2015
Both theoretical predictions and observations of the very nearby Universe suggest that low-mass galaxies (log$_{10}$[M$_{*}$/M$_{\odot}$]

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.

Probing the Physics of Interacting Galaxies

Astrophysics and Space Science, 2003
Both Arp 140 and Arp 104 reveal extended tidal tails in the HI. The Halpha and FIR fluxes of Arp 140 yield similar SFR of ~0.8 solar masses per year. In contrast the Halpha flux of Arp 104 yields a SFR of ~0.05 solar masses per year, ~ 20 times smaller than that obtained from the FIR flux.
