A central question regarding ultra-diffuse galaxies (UDGs) is whether they are in a separate category from low-surface-brightness (LSB) galaxies, or just their natural continuation toward low stellar masses. In this Letter, we show that the rotation curve of the gas rich UDG AGC 242019 is well fit by a dark matter halo with an inner slope that asymptotes to ~-0.54, and that such a fit provides a concentration parameter that matches theoretical expectations. This finding, together with previous works in which shallow inner profiles are derived for UDGs, shows that the structural properties of

The eruption on La Palma has provided a unique scenario for testing the DRAGO instrument, the infrared camera of the Instituto de Astrofísica de Canarias (IAC) which has been observing the Canary Islands from space since January. One of the objectives for which DRAGO was designed is monitoring natural disasters, especially those which could occur in the Canaries, such as forest fires, petroleum spills, or volcanic eruptions. The role of DRAGO is to provide infrared images from space to help the management and control of these disasters. In the case of the eruption which began on September

The Instituto de Astrofísica de Canarias wants to extend its solidarity and support to the island of La Palma, to all who are suffering the consequences of the volcanic eruption, and especially to those who had to abandon their homes or have suffered damages to their properties. We share the pain that this has caused them and the wish for the circumstances to change for the better as soon as possible. The authorities and all the institutions involved in the emergency plan have the material and staff resources of the IAC at their disposal for whatever they consider necessary.
