The Fornax Deep Survey (FDS) with the VST XI. The search for signs of preprocessing between the Fornax main cluster and Fornax A group

no code implementations14 Jan 2021 Alan H. Su, Heikki Salo, Joachim Janz, Eija Laurikainen, Aku Venhola, Reynier F. Peletier, Enrica Iodice, Michael Hilker, Michele Cantiello, Nicola Napolitano, Marilena Spavone, Maria A. Raj, Glenn van de Ven, Steffen. Mieske, Maurizio Paolillo, Massimo Capaccioli, Edwin A. Valentijn, Aaron E. Watkins

Overall, we find significant differences in the distributions of quantities derived from S\'ersic profiles ($g'-r'$, $r'-i'$, $R_e$, and $\bar{\mu}_{e, r'}$), and non-parametric indices ($A$ and $S$) between the Fornax main cluster and Fornax A group.

LAAT: Locally Aligned Ant Technique for discovering multiple faint low dimensional structures of varying density

1 code implementation17 Sep 2020 Abolfazl Taghribi, Kerstin Bunte, Rory Smith, Jihye Shin, Michele Mastropietro, Reynier F. Peletier, Peter Tino

The algorithm performance in comparison to state-of-the-art approaches for noise reduction in manifold detection and clustering is demonstrated, on several synthetic and real datasets, including an N-body simulation of a cosmological volume.

The number of globular clusters around the iconic UDG DF44 is as expected for dwarf galaxies

no code implementations25 Jun 2020 Teymoor Saifollahi, Ignacio Trujillo, Michael A. Beasley, Reynier F. Peletier, Johan H. Knapen

We conclude that the number of GCs around DF44 is as expected for regular dwarf galaxies of similar stellar mass and DF44 is not extraordinary in this respect.

The kinematics of local thick discs do not support an accretion origin

no code implementations29 Jan 2019 Sébastien Comerón, Heikki Salo, Johan H. Knapen, Reynier F. Peletier

Literature numerical studies of dynamical friction allow us to estimate that at the current cosmic time about one in six mergers for which the stars of the accreted galaxy ended in a thick disc were retrograde.
