Star formation in disk galaxies and its relation with spiral structure in numerical simulations

David Felipe Barros Ramirez, Juan Carlos Muñoz-Cuartas

The spiral structure of a spiral galaxy can be seen through different observational tracers such as the dust in the interstellar medium, the free electrons in ionized regions, the…

Simulating the galactic system in interaction AM 2229-735 and the formation of its polar structure

Luis F. Quiroga, Juan C. Muñoz-Cuartas, Irapuan Rodrigues +1

We study the formation of polar ring galaxies via minor mergers. We used N-body+hydrodynamics simulations to reproduce the dynamics of the observed system AM 2229-735 that is a min…

Substructures in Minor Mergers' Tidal Streams

D. A. Noreña, J. C. Muñoz-Cuartas, L. F. Quiroga +1

In this work, we explore the idea that substructures like stellar clusters could be formed from the tidal stream produced in galactic minor mergers. We use -body and SPH simulat…

Galaxy Cluster Mass Reconstruction Project - IV. Understanding the effects of imperfect membership on cluster mass estimation

R. Wojtak, L. Old, G. A. Mamon +17

The primary difficulty in measuring dynamical masses of galaxy clusters from galaxy data lies in the separation between true cluster members from interloping galaxies along the lin…

Quantifying and controlling biases in dark matter halo concentration estimates

C. N. Poveda-Ruiz, J. E. Forero-Romero, J. C. Muñoz-Cuartas

We use bootstrapping to estimate the bias of concentration estimates on N-body dark matter halos as a function of particle number. We find that algorithms based on the maximum radi…

Galaxy Cluster Mass Reconstruction Project: II. Quantifying scatter and bias using contrasting mock catalogues

L. Old, R. Wojtak, G. A. Mamon +21

This article is the second in a series in which we perform an extensive comparison of various galaxy-based cluster mass estimation techniques that utilise the positions, velocities…
