The isolated elliptical galaxy NGC 5812 -- MOND or Dark Matter?
Tom Richtler, Ricardo Salinas, Richard Lane +1
There exist isolated elliptical galaxies, whose dynamics can be modelled without resorting to dark matter or MOND, e.g. NGC 7507. The isolated elliptical NGC 5812 is another object…
SDSS IV MaNGA: Bar pattern speed in Milky Way Analogue galaxies
Luis Garma-Oehmichen, Héctor Hernández-Toledo, Erik Aquino-Ortíz +8
Most secular effects produced by stellar bars strongly depend on the pattern speed. Unfortunately, it is also the most difficult observational parameter to estimate. In this work,…
The curious case of the companion: evidence for cold accretion onto a dwarf satellite near the isolated elliptical NGC 7796
T. Richtler, M. Hilker, K. Voggel +4
The isolated elliptical (IE) NGC 7796 is accompanied by an interesting early-type dwarf galaxy, named NGC7796-DW1. It exhibits a tidal tail, very boxy isophotes, and multiple nucle…
Isolated elliptical galaxies and their globular cluster systems. II. NGC 7796 - globular clusters, dynamics, companion
T. Richtler, R. Salinas, R. R. Lane +2
We investigate the globular cluster system of the isolated elliptical NGC 7796, present new photometry of the galaxy, and use published kinematical data to constrain the dark matte…
