MEGARA Stellar Spectral Library. Second Release
E. Carrasco, M. Lira-Franco, M. L. García-Vargas +6
We present the second release of the MEGARA spectral library, MEGASTAR, which now includes all spectra collected during ten observing semesters at the Gran Telescopio CANARIAS. Thi…
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…
MEGARA-GTC Stellar Spectral Library (II). MEGASTAR First Release
E. Carrasco, M. Mollá, M. L. García-Vargas +4
MEGARA is an optical integral field and multiobject fibre based spectrograph for the 10.4m Gran Telescopio CANARIAS that offers medium to high spectral resolutions (FWHM) of R $\si…
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 (…
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…
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…
