The Splash without a merger
João A. S. Amarante, Leandro Beraldo e Silva, Victor P. Debattista +1
The Milky Way's progenitor experienced several merger events which left their imprints on the stellar halo, including the Gaia-Sausage/Enceladus. Recently, it has been proposed tha…
Revealing the cosmic evolution of boxy/peanut-shaped bulges from HST COSMOS and SDSS
Sandor J. Kruk, Peter Erwin, Victor P. Debattista +1
Vertically thickened bars, observed in the form of boxy/peanut (B/P) bulges, are found in the majority of massive barred disc galaxies in the local Universe, including our own. B/P…
A New Channel of Bulge Formation via The Destruction of Short Bars
Minghao Guo, Min Du, Luis C. Ho +2
Short (inner) bars of sub-kiloparsec radius have been hypothesized to be an important mechanism for driving gas inflows to small scales, thus feeding central black holes. Recent nu…
Box/peanut-shaped bulges in action space
Victor P. Debattista, David J. Liddicott, Tigran Khachaturyants +1
We introduce the study of box/peanut (B/P) bulges in the action space of the initial axisymmetric system. We explore where populations with different actions end up once a bar form…
Geometric properties of galactic discs with clumpy episodes
Leandro Beraldo e Silva, Victor P. Debattista, Tigran Khachaturyants +1
A scenario for the formation of the bi-modality in the chemical space [/Fe] vs [Fe/H] of the Milky Way was recently proposed in which -enhanced stars are produced early and q…
A MUSE study of the fast bar in the weakly-interacting galaxy NGC 4264
V. Cuomo, E. M. Corsini, J. A. L. Aguerri +1
We present surface photometry and stellar kinematics of NGC 4264, a lenticular galaxy in the region of the Virgo Cluster undergoing a tidal interaction with its neighbour, NGC 4261…
