Magnetic Field Evolution in Isolated and Interacting Spiral Galaxies [PDF]
, 2011 This doctoral thesis covers the question about the existence and evolution of magnetic fields in galaxies. The kinematic evolution of magnetic fields in isolated spiral galaxies as well as their self- consistent evolution in interacting spirals is studied ...

Dust Deficiency in the Interacting Galaxy NGC 3077
Galaxies, 2017 Using 70 μ m observations taken with the PACS instrument of the Herschel space telescope, the dust content of the nearby and interacting spiral galaxy NGC 3077 has been compared with the dust content of the isolated galaxies such as NGC 2841, NGC ...

Identification and Investigation of Interacting Galaxies Using Spatially Resolved Data
, 2019 Galaxy interactions are known to trigger episodes of star formation, and are an important process in galaxy evolution. Despite its importance, however, there are still many unknowns.

Quantifying the FIR interaction enhancement in paired galaxies [PDF]
, 1990 The Catalog of Isolated Pairs of Galaxies in the Northern Hemisphere, by Karachentsev (1972), was studied and a well-matched comparison sample taken from the Catalog of Isolated Galaxies, by Karachentseva (1973), in order to quantify the enhanced FIR ...

Secondary evolution of galaxies investigated by N-body simulations [PDF]
, 2008 In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

The nature and origin of disky elliptical galaxies [PDF]
, 2002 The observational trend that disky elliptical galaxies exhibit younger luminosity- weighted ages than boxy ellipticals is investigated. The presence of a possible young stellar disk embedded in these galaxies is explored by comparing kinematics derived ...

A Fast Radio Burst in a Compact Galaxy Group at z ∼ 1
The Astrophysical Journal LettersFRB 20220610A is a high-redshift fast radio burst (FRB) that has not been observed to repeat. Here, we present rest-frame UV and optical Hubble Space Telescope observations of the field of FRB 20220610A. The imaging reveals seven extended sources, one of

Paired and interacting galaxies: Conference summary [PDF]
, 1990 The author gives a summary of the conference proceedings. The conference began with the presentation of the basic data sets on pairs, groups, and interacting galaxies with the latter being further discussed with respect to both global properties and ...
