Low-mass Active Galaxies in the SAMI Galaxy Survey with Spatially Resolved Spectroscopy

The Astrophysical Journal
The smallest supermassive black holes (BHs), which provide constraints on BH seeds, reside in low-mass galaxies. Here, we present a systematic analysis of 990 low-mass galaxies in the SAMI Galaxy Survey to identify emission from accreting BHs using ...

Integral field spectroscopy of late-type galaxies

, 2019
Diese Dissertation befasst sich mit der Analyse der Ionisationsstruktur und Kinematik lokaler Starburst-Zwerggalaxien mit niedriger Metallizität unter Verwendung von Integralfeldspektroskopie. Dieser Typ Galaxie dienet als Analogon zu weit entfernten Galaxien bei hoher Rotverschiebung. Als vergleich dienten zwei Datensätze von Starburst-Spiralgalaxien.
