Mapping the ionized gas of the metal-poor HII galaxy PHL 293B with MEGARA

C. Kehrig, J. Iglesias-Paramo, J. M. Vilchez +14

Here we report the first spatially resolved spectroscopic study for the galaxy PHL293B using the high-resolution GTC/MEGARA IFU. PHL293B is a local, extremely metal-poor, high ioni…

Spatially-resolved analysis of neutral winds, stars and ionized gas kinematics with MEGARA/GTC: new insights on the nearby galaxy UGC 10205

C. Catalán-Torrecilla, Á. Castillo-Morales, A. Gil de Paz +15

We present a comprehensive analysis of the multi-phase structure of the interstellar medium (ISM) and the stellar kinematics in the edge-on nearby galaxy UGC 10205 using integral f…

The extended HeII4686-emitting region in IZw18 unveiled: clues for peculiar ionizing sources

C. Kehrig, J. M. Vilchez, E. Perez-Montero +5

New integral field spectroscopy has been obtained for IZw18, the nearby lowest-metallicity galaxy considered our best local analog of systems forming at high-z. Here we report the…
