General
Nuestro proyecto puede dividirse en dos líneas principales de investigación. En primer lugar, el estudio de los vientos producidos por cuásares luminosos oscurecidos y del impacto que estos tienen en sus galaxias anfitrionas (retroalimentación del AGN). Para ello hemos obtenido observaciones infrarrojas y ópticas con los instrumentos del Gran Telescopio CANARIAS (GTC) CanariCam, EMIR y MEGARA, así como datos de ALMA en el rango milimétrico. Parte de esta investigación la realizamos en el marco de la Innovative Training Network BID4BEST, del programa H2020. Nuestro grupo está también fuertemente involucrado en el consorcio internacional GATOS (Galactic Activity, Torus and Outflow Survey), creado con el objetivo de conseguir tiempo en el JWST y ALMA para caracterizar el ciclo del gas y el material que oscurece el núcleo de galaxias activas cercanas. En segundo lugar, nuestra actividad se centra en la aplicación de la espectroscopia de campo integral al estudio de objetos extensos tales como galaxias con formación estelar o galaxias activas para investigar el encendido de ambos fenómenos. Asimismo, contribuimos al desarrollo de nuevos instrumentos y técnicas de análisis de datos relacionadas con la espectroscopia 3D. En particular, participamos en el desarrollo del espectrógrafo de campo integral de alta resolución HARMONI, uno de los instrumentos de primera luz del Extremely Large Telescope de la ESO.

Publicación de una letter en MNRAS donde estudiamos la conexión entre los vientos de gas ionizado y las poblaciones estelares jóvenes en el cuásar de tipo 2 Mrk 34 (Bessiere & Ramos Almeida 2022). Encontramos evidencias de retroalimentación positiva y negativa en distintas partes de la misma galaxia, inducidas por el viento. Este trabajo, parte del proyecto QSOFEED, abre una nueva ventana a la investigación del impacto directo de la actividad nuclear en la formación estelar en galaxias.

Publicación de un estudio detallado sobre la cinemática del gas ionizado y molecular templado en el cuásar de tipo 2 J0945+1737, parte de la muestra QSOFEED (Speranza et al. 2022). Encontramos evidencias de un viento de gas ionizado con un outflow mass rate máximo de 51 Msun/yr, y ausencia de su contrapartida de gas molecular templado.

The largely unconstrained multiphase nature of outflows in AGN host galaxiesObservations and simulations show that outflows in active galactic nuclei contain gas in different phases. To understand their true impact on galaxy evolution, we advocate consistent and unbiased investigation of these multiphase winds in large active galactic nuclei samples.Cicone, C. et al.

An UXor among FUors: Extinction-related Brightness Variations of the Young Eruptive Star V582 AurV582 Aur is an FU Ori-type young eruptive star in outburst since ∼1985. The eruption is currently in a relatively constant plateau phase, with photometric and spectroscopic variability superimposed. Here we will characterize the progenitor of the outbursting object, explore its environment, and analyze the temporal evolution of the eruption. We areÁbrahám, P. et al.

Quantifying the AGN-driven outflows in ULIRGs (QUADROS) - I: VLT/Xshooter observations of nine nearby objectsAlthough now routinely incorporated into hydrodynamic simulations of galaxy evolution, the true importance of the feedback effect of the outflows driven by active galactic nuclei (AGN) remains uncertain from an observational perspective. This is due to a lack of accurate information on the densities, radial scales and level of dust extinction ofRose, M. et al.

A 100 kpc nebula associated with the `Teacup' fading quasarWe report the discovery of an ˜100 kpc ionized nebula associated with the radio-quiet type 2 quasar (QSO2) nicknamed the `Teacup' (z = 0.085). The giant nebula is among the largest known around active galaxies at any z. We propose that it is part of the circumgalactic medium (CGM) of the QSO2 host, which has been populated with tidal debris byVillar-Martín, M. et al.

We map the interstellar medium (ISM) including the diffuse interstellar bands (DIBs) in absorption toward the globular cluster NGC 6397 using VLT/MUSE. Assuming the absorbers are located at the rim of the Local Bubble we trace structures on the order of mpc (milliparsec, a few thousand AU).

Nuclear obscuration in active galactic nucleiThe material surrounding accreting supermassive black holes connects the active galactic nucleus with its host galaxy and, besides being responsible for feeding the black hole, provides important information on the feedback that nuclear activity produces on the galaxy.

The Wolf-Rayet star population in the dwarf galaxy NGC 625Context. Quantifying the number, type, and distribution of Wolf-Rayet (W-R) stars is a key component in the context of galaxy evolution, since they put constraints on the age of the star formation bursts. Nearby galaxies (distances ≲5 Mpc) are particularly relevant in this context since they fill the gap between studies in the Local Group, whereMonreal-Ibero, A. et al.

Polarization of the changing-look quasar J1011+5442If the disappearance of the broad emission lines observed in changing-look quasars were caused by the obscuration of the quasar core through moving dust clouds in the torus, high linear polarization typical of type 2 quasars would be expected. We measured the polarization of the changing-look quasar J1011+5442 in which the broad emission lines haveHutsemékers, D. et al.

A comparison between the soft X-ray and [O III] morphologies of active galactic nucleiSeveral studies of nearby active galactic nuclei (AGNs) have shown that the soft X-ray emission presents a size and morphology resembling that of the narrow-line region (NLR) traced by [O III]. Since the NLR is mainly constituted by gas photoionized by the AGN, it seems logical to assume that this is also the primary source of the soft X-rayGómez-Guijarro, Carlos et al.

Hints on the Gradual Resizing of the Torus in AGNs through Decomposition of Spitzer/IRS SpectraSeveral authors have claimed that less luminous active galactic nuclei (AGNs) are not capable of sustaining a dusty torus structure. Thus, a gradual resizing of the torus is expected when the AGN luminosity decreases. Our aim is to examine mid-infrared observations of local AGNs of different luminosities for the gradual resizing and disappearanceGonzález-Martín, Omaira et al.

Survival of the Obscuring Torus in the Most Powerful Active Galactic NucleiDedicated searches generally find a decreasing fraction of obscured active galactic nuclei (AGN) with increasing AGN luminosity.
