1) In this brief seminar (<~25 minutes+questions) I will present recent results on the study of "deep", high resolution, surface brightness profiles of a sample...
Charla(1) Stellar disks in the intermediate redshift range: listening to the galaxy evolution "Symphony". (2) Unveiling the narrow-line Seyfert 1 nature of Mrk 573 using near-infrared spectroscopy
Publicación3D Spectroscopy with GTC-MEGARA of the Triple AGN Candidate in SDSS J102700.40+174900.8
Triple-active galactic nucleus (AGN) systems are expected to be the result of the hierarchical model of galaxy formation. Since there are very few of them...
PublicaciónA Reemerging Bright Soft X-Ray State of the Changing-look Active Galactic Nucleus 1ES 1927+654: A Multiwavelength View
1ES1927+654 is a nearby active galactic nucleus (AGN) that has shown an enigmatic outburst in optical/UV followed by X-rays, exhibiting strange variability...
PublicaciónA search for new objects in the transition phase between AGB-stars and planetary nebulae
Preliminary results are presented from a spectroscopy survey of IRAS sources with colors similar to those of planetary nebulae. Two new planetary nebulae, some...
PublicaciónAccretion tori and cones of ionizing radiation in Seyfert galaxies
The photoionization of extended narrow-line regions in Seyfert galaxies by the radiation produced in a thick accretion disk is studied. The emission-line...
CharlaActive galactic nuclei synapses: X-ray versus optical classifications using artificial neural networks
The active galactic nuclei is conformed by a number of classes. Optically they are defined using diagnostics based on optical emission lines. At X-rays they are...
PublicaciónBASS. XXV. DR2 Broad-line-based Black Hole Mass Estimates and Biases from Obscuration
We present measurements of broad emission lines and virial estimates of supermassive black hole masses (M BH) for a large sample of ultrahard X-ray-selected...
PublicaciónBidimensional spectroscopy of Seyfert galaxies: offset BLR in NGC 3227.
PublicaciónBidimensional spectroscopy of the central kiloparsec of NGC 4151
Sixty-one bidimensionally distributed spectra covering the circumnuclear region of NGC 4161 within a radius of about 6.5 arcsec are presented. The local...
