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 (12.5 arcsec × 11.3 arcsec) of the active galaxy NGC 7469, at spatial scales of 0.62 arcsec. We explore the kinematics, dynamics, ionization mechanisms, and oxygen abundances of the ionized gas, by modelling the H α-[N ii] emission lines at high signal-to-noise (> 15) with multiple Gaussian components. MEGARA observations… 
MUSE Reveals Extended Circumnuclear Outflows in the Seyfert 1 NGC 7469
NGC 7469 is a well-known luminous infrared galaxy, with a circumnuclear star formation ring (∼830 pc radius) surrounding a Seyfert 1 active galactic nucleus (AGN). Nuclear unresolved winds were
A proto-pseudobulge in ESO 320-G030 fed by a massive molecular inflow driven by a nuclear bar
Galaxies with nuclear bars are believed to efficiently drive gas inward, generating a nuclear starburst and possibly an active galactic nucleus. We confirm this scenario for the isolated,
Planetary nebulae with Wolf–Rayet-type central stars – II. Dissecting the compact planetary nebula M 2-31 with GTC MEGARA
We present a comprehensive analysis of the compact planetary nebula M 2-31 investigating its spectral properties, spatio-kinematical structure, and chemical composition using Gran Telescopio
Tomography of the Unique Ongoing Jet in the Planetary Nebula NGC 2392
Jets (fast collimated outflows) are claimed to be the main shaping agent of the most asymmetric planetary nebulae (PNs), as they impinge on the circumstellar material at late stages of the asymptotic
Chemical abundances in the nuclear region of nearby galaxies from the Palomar Survey
We estimate chemical abundances and ionization parameters in the nuclear region of a sample of 143 galaxies from the Palomar Spectroscopic Survey, composed by Star-Forming Galaxies (87), Seyferts 2
ALMA Observations of Multiple CO and C Lines toward the Active Galactic Nucleus of NGC 7469: An X-Ray-dominated Region Caught in the Act
We used the Atacama Large Millimeter/submillimeter Array (ALMA) to map $^{12}$CO($J$ = 1-0), $^{12}$CO($J$ = 2-1), $^{12}$CO($J$ = 3-2), $^{13}$CO($J$ = 2-1), and [CI]($^3P_1$-$^3P_0$) emission lines


Molecular line emission in NGC 1068 imaged with ALMA: I. An AGN-driven outflow in the dense molecular gas
Aims. We investigate the fueling and the feedback of star formation and nuclear activity in NGC 1068, a nearby (D = 14 Mpc) Seyfert 2 barred galaxy, by analyzing the distribution and kinematics of
Spatially resolved optical integral field unit spectroscopy of the inner superwind of NGC 253
We present optical integral field unit (IFU) observations (VLT/VIMOS-IFU and WIYN/SparsePak), and associated archival deep Hα imaging (MPG/ESO 2.2 m WFI), of the nearby starburst galaxy NGC 253. With
High Spatial Resolution Mid-Infrared Observations of Three Seyfert Galaxies
Images at 12.5 μm of nuclei of three nearby Seyfert galaxies—NGC 1275, NGC 4151, and NGC 7469—have been obtained with the 10 m Keck Telescope. NGC 7469 is resolved and deconvolution delineates a
Giant H ii regions in NGC 7479 and NGC 6070: GH iiRs in NGC 7479 and NGC 6070
We present new results from our search for giant H II legions in galaxies visible from the Southern hemisphere. In this work we study two galaxies: NGC 7479 and NGC 6070. Using high-resolution
Resolving the Stellar Populations in the Circumnuclear Ring of NGC 7469
We investigate the stellar populations in the star-forming ring of the luminous infrared galaxy NGC 7469. We use HST multiwavelength (UV through NIR) imaging complemented with new K-band ground-based
The Nuclear Gasdynamics and Star Formation of NGC 7469
