Planetary nebulae, the descendants of low- and intermediate-mass stars, have characteristic onion-like ionization structure, with the highest ionization species closer to the central star. This is true for all planetary nebulae, but HuBi 1, which shows an inverted ionization inner shell.

The Balmer emission originated in the broad line region (BLR) of active galactic nuclei (AGNs) could be either weak and difficult to detect, or even absent, for low luminosity AGNs,  as low ionization nuclear emission-line regions (LINERs).

Tidal disruption events (TDEs) are transient flares produced when a star is ripped apart by the gravitational field of a supermassive black hole (SMBH).

The study of the AGN accreting close to the Eddington limit (L/LEdd~1) has taken an important role, due to their potential use as standard candles for cosmological applications.  With the purpose to understand the physics of extreme quasar, we perform a spectroscopic analysis of a sample of highl

Under unification schemes, active galactic nuclei (AGN) can be explained by orientation effects. However, some sources show properties at different frequencies that led to incongruent classifications and cannot be explained by such unification scheme.

I will review the status of the SN-GRB connection. Present data suggest that SNe associated with GRBs form a heterogeneous class of objects including both bright and faint Hypernovae. Some of the special conditions requested by a massive star to become a GRB are discussed.

Today, stellar and planetary physics enjoy an unprecedented boost thanks to space technology.

In the class of active galactic nuclei (AGNs), blazars are the most extreme objects, with their relativistic jets closely aligned to our line-of-sight.

Stellar activity can provide important information regarding the structure, evolution, and the atmosphere of the stars, as well as their magnetic filed and mechanisms that generate them.

Lightning has been studied for centuries with surprisingly meager progress since the early breakthroughs of Franklin.

Hubble images of the amazing symmetries of young planetary nebulae have captured the imagination of the public. Scientifically, unravelling the physics of their ejection histories is the ultimate goal.

The Observatorio Astrofísico de Javalambre (OAJ) is an astronomical infrastructure conceived to carry out large sky, multi-filter astronomical surveys from the Northern hemisphere.

MEGARA, the optical multi-object spectrograph (MOS) for the GTC 10m telescope, has been developed by a Consortium whose partners are UCM, INAOE, IAA-CSIC and UPM.

A pioneering long term program at the IRAM 30m Telescope dubbed POLAMI (Polarimetric Monitoring of AGN with Millimetre Wavelengths) observes the 4 Stokes parameters of the continuum emission at 3.5 and 1.3 mm, with a time sampling of ~2 weeks for the ~40 brighter sources in the northern sky.

The Observatorio Astrofísico de Javalambre (OAJ), managed and operated by the Centro de Estudios de Física del Cosmos de Aragón (CEFCA), is mostly devoted to conduct large sky multi-filter surveys with two large field of view telescopes of 2.5m and 80cm and their respective panoramic instrumentat

Un proyecto de la ESA acogido en el Parque de las Ciencias para fomentar las vocaciones científico-tecnológicas en las primeras etapas educativas, haciendo uso del contexto del espacio.

The advent of Integral Field Spectroscopy (IFS) applied to supernova (SN) environmental studies have shown the potential of this technique to directly characterize the galactic environmental parameters at SN locations, compare them to those at different locations of the galaxy, and put constraint

The chemistry of carbon in evolved stars will be discussed from the observational and chemical modelling point of view.

Ultra-compact dwarf galaxies (UCDs) are predominatly found in the cores of nearby galaxy clusters, regions that are dominated by early-type galaxies, among them nucleated dwarf ellipticals.

We investigate the cosmic evolution of the absolute and specific star formation rate (SFR, sSFR) of galaxies as derived from a spatially-resolved study of the stellar populations in a set of nearby galaxies from the CALIFA survey.

I will present the evolution of the “Cosmic Flows” program spanning ten years of research since its inception in 2006. From CF1 to the latest CF3 data-set, an order of magnitude in the number of observational galaxy distances is gained, meanwhile the cosmographied volume is multiplied by 150.

The luminous S-star cluster in the Galactic center allows us to study the physics close to a super-massive black hole including distinctive dynamical tests of general relativity.

We use spatially resolved spectroscopy from the CALIFA survey to study the nature of the line emitting gas in galaxies of different Hubble types, focusing on the separation of star-forming (SF) regions from those better characterized as diffuse ionized gas (DIG).
