Exploring the evolution of a dwarf spheroidal galaxy with SPH simulations: II. AGN feedback

R. Hazenfratz, P. Barai, G. A. Lanfranchi +1

We investigate AGN feedback from an intermediate-mass black hole at the center of a dwarf spheroidal galaxy, by performing isolated galaxy simulations using a modified version of t…

Exploring the evolution of a dwarf spheroidal galaxy with SPH simulations: I. Stellar feedback

Roberto Hazenfratz, Paramita Barai, Gustavo A. Lanfranchi +1

A fundamental question regarding the evolution of dwarf spheroidal galaxies is the identification of the key physical mechanisms responsible for gas depletion. Here, we focus on th…

Boundary conditions in hydrodynamic simulations of isolated galaxies and their impact on the gas-loss processes

Anderson Caproni, Gustavo A. Lanfranchi, Amâncio C. S. Friaça +1

Three-dimensional hydrodynamic simulations are commonly used to study the evolution of the gaseous content in isolated galaxies, besides its connection with galactic star formation…

Parameterizing the Outflow from a Central Black Hole in Dwarf Spheroidal Galaxies: A 3D Hydrodynamic Simulation

Gustavo A. Lanfranchi, Roberto Hazenfratz, Anderson Caproni +1

Large galaxies harbor massive central black holes and their feedback causes a substantial impact in their evolution. Recently, observations suggested that dwarf galaxies might host…

Evolution of neutron capture elements in dwarf galaxies

Marta Molero, Donatella Romano, Moritz Reichert +6

We study the evolution of Eu and Ba abundances in local group dwarf spheroidal and ultra faint dwarf galaxies by means of detailed chemical evolution models and compare our results…

The S2 Stream: the shreds of a primitive dwarf galaxy

David S. Aguado, G. C. Myeong, Vasily Belokurov +12

The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream. We…
