Spatially-resolved properties of the ionized gas in the HII galaxy J084220+115000
D. Fernández-Arenas, E. Carrasco, R. Terlevich +20
We present a spatially resolved spectroscopic study for the metal poor HII galaxy J084220+115000 using MEGARA Integral Field Unit observations at the Gran Telescopio Canarias. We e…
Once in a blue stream: Detection of recent star formation in the NGC 7241 stellar stream with MEGARA
David Martinez-Delgado, Santi Roca-Fabrega, Armando Gil de Paz +23
In this work we study the striking case of a narrow blue stream around the NGC 7241 galaxy and its foreground dwarf companion. We want to figure out if the stream was generated by…
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…
MEGARA-IFU detection of extended HeII4686 nebular emission in the central region of NGC1569 and its ionization budget
Y. D. Mayya, E. Carrasco, V. M. A. Gomez-Gonzalez +21
We here report the detection of extended HeII4686 nebular emission in the central region of NGC1569 using the integral field spectrograph MEGARA at the 10.4-m Gran Telescopio Canar…
NGC 7469 as seen by MEGARA: new results from high-resolution IFU spectroscopy
S. Cazzoli, A. Gil de Paz, I. Márquez +13
We present our analysis of high-resolution (R 20 000) GTC/MEGARA integral-field unit spectroscopic observations, obtained during the commissioning run, in the inner region (…
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…
High-resolution MEGARA IFU spectroscopy and structural analysis of a fast-rotating, disky bulge in NGC 7025
Bililign T. Dullo, Mario Chamorro-Cazorla, Armando Gil de Paz +12
Disky bulges in spiral galaxies are commonly thought to form out of disk materials (mainly) via bar driven secular processes, they are structurally and dynamically distinct from `c…
