The jet/counter-jet symmetry of the HH 212 outflow

A. Noriega-Crespo, A. C. Raga, V. Lora +7

We present Spitzer (IRAC) images observations and a VLT 2.1micron image of the HH 212 outflow. We find that this outflow has a strong symmetry, with jet/counterjet knot pairs with…

Flipping-up the field: gravitational feedback as a mechanism for young clusters dispersal

Manuel Zamora-Avilés, Javier Ballesteros-Paredes, Jesús Hernández +3

Recent analyses of Gaia data have provided direct evidence that most young stellar clusters are in a state of expansion, with velocities of the order of ~0.5 km/s. Traditionally, e…

Cold, old and metal-poor: New stellar substructures in the Milky Way's dwarf spheroidals

V. Lora, E. K. Grebel, S. Schmeja +1

Dwarf spheroidal galaxies (dSph) orbiting the Milky Way are complex objects often with complicated star formation histories and internal dynamics. In this work, we search for stell…

An upper limit on the mass of the black hole in Ursa Minor dwarf galaxy

V. Lora, F. J. Sanchez-Salcedo, A. Raga +1

The well-established correlations between the mass of massive black holes (BHs) in the nuclei of most studied galaxies and various global properties of their hosting galaxy lend su…

Bounds on the mass and abundance of dark compact objects and black holes in dwarf spheroidal galaxy halos

F. J. Sanchez-Salcedo, V. Lora

We establish new dynamical constraints on the mass and abundance of compact objects in the halo of dwarf spheroidal galaxies. In order to preserve kinematically cold the second pea…
