Testing MOND gravity in the shell galaxy NGC 3923
Michal Bilek, Bruno Jungwiert, Lucie Jilkova +3
Context. The elliptical galaxy NGC 3923 is surrounded by numerous stellar shells that are concentric arcs centered on the galactic core. They are very likely a result of a minor me…
Quadruple-peaked spectral line profiles as a tool to constrain gravitational potential of shell galaxies
Ivana Ebrova, Lucie Jilkova, Bruno Jungwiert +5
Stellar shells observed in many giant elliptical and lenticular as well as a few spiral and dwarf galaxies, presumably result from galaxy mergers. Line-of-sight velocity distributi…
Comparing Various Approaches to Simulating the Formation of Shell Galaxies
Ivana Ebrova, Katerina Bartoskova, Bruno Jungwiert +2
The model of a radial minor merger proposed by Quinn (1984), which successfully reproduces the observed regular shell systems in shell galaxies, is ideal for a test-particle simula…
Quadruple-peaked Line-of-sight Velocity Distributions in Shell Galaxies
Ivana Ebrova, Lucie Jilkova, Bruno Jungwiert +4
We present an improved study of the expected shape of the line-of-sight velocity distribution in shell galaxies. We found a simple analytical expression connecting prominent and in…
Simulations of shell galaxies with GADGET-2: Multi-generation shell systems
Kateřina Bartošková, Bruno Jungwiert, Ivana Ebrová +2
As the missing complement to existing studies of shell galaxies, we carried out a set of self-consistent N-body simulations of a minor merger forming a stellar shell system within…
Simulations of Line Profile Structure in Shell Galaxies
L. Jilkova, B. Jungwiert, M. Krizek +4
In the context of exploring mass distributions of dark matter haloes in giant ellipticals, we extend the analysis carried out Merrifield and Kuijken (1998) for stellar line profile…
