Utilizing Shell Galaxies
Ivana Ebrová, Michal Bílek, Bruno Jungwiert
Stellar shells are low surface brightness features in the form of open, concentric arcs, formed in close-to-radial collisions of galaxies. They occur in at least 10% of early-type…
Deep imaging of the shell elliptical galaxy NGC3923 with MegaCam
Michal Bílek, Jean-Charles Cuillandre, Stephen Gwyn +4
Context. The elliptical galaxy NGC 3923 is known to be surrounded by a number of stellar shells, probable remnants of an accreted galaxy. Despite its uniqueness, the deepest images…
MOND implications for spectral line profiles of shell galaxies: shell formation history and mass-velocity scaling relations
Michal Bílek, Bruno Jungwiert, Ivana Ebrová +1
Context. Many ellipticals are surrounded by round stellar shells probably stemming from minor mergers. A new method for constraining gravitational potential in elliptical galaxies…
CALIFA, the Calar Alto Legacy Integral Field Area survey. III. Second public data release
R. García-Benito, S. Zibetti, S. F. Sánchez +68
This paper describes the Second Public Data Release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. The data for 200 objects are made public, including the 100…
Shell galaxies as laboratories for testing MOND
Michal Bílek, Ivana Ebrová, Bruno Jungwiert +2
Tests of MOND in ellipticals are relatively rare because these galaxies often lack kinematic tracers in the regions where the MOND effects are significant. Stellar shells observed…
Stellar Population gradients in galaxy discs from the CALIFA survey
P. Sanchez-Blazquez, F. Rosales-Ortega, J. Mendez-Abreu +27
While studies of gas-phase metallicity gradients in disc galaxies are common, very little has been done in the acquisition of stellar abundance gradients in the same regions. We pr…
