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…
MEGARA-GTC Stellar Spectral Library (I)
M. L. García-Vargas, E. Carrasco, M. Mollá +11
MEGARA (Multi Espectr{ó}grafo en GTC de Alta Resoluci{ó}n para Astronom{\'ı}a) is an optical (3650~--~9750Å), fibre-fed, medium-high spectral resolution (R = 6000, 12000, 20000) in…
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…
A new approach in data reduction: proper handling of random errors and image distortions
N. Cardiel, J. Gorgas, J. Gallego +5
Data reduction procedures are aimed to minimize the impact of data acquisition imperfections on the measurement of data properties with a scientific meaning for the astronomer. To…
