The effect of temperature fluctuations in the spectra of ionized nebulae was firstly explored by Peimbert (1967). Since then, the problem of their existence has...
Are the extended narrow line regions in AGN photoionized by the emission from thick accretion disks?
We study the photoionization of the Extended Narrow Line Region (ENLR) using three anisotropic radiation fields: (1) a geometrically thick accretion disk; (2) a...
We present the visible spectrum of asteroid-comet transition object 133P/Elst-Pizarro (7968), the first member of the new population of objects called Main Belt...
Are the stellar winds in IC 1613 stronger than expected?
In this poster we present the results of our analyses of three early massive stars in IC 1613, whose spectra have been observed with VIMOS and analyzed with...
We present the detection of a sample of galaxies which are extremely faint in the optical and near-infrared but bright at mid-infrared wavelengths. This...
Are We Missing Something Beyond the Mass from Post-Common-Envelopes PNe?
Planetary nebulAE(PNe) arising from common envelope (CE) interaction represent a kind of embarrassing binary. Asymptotic Giant Branch (AGB) stars in close...
Ariel - The ESA M4 Space Mission to Focus on the Nature Of Exoplanets
Ariel, the atmospheric remote-sensing infrared exoplanet large-survey, is the recently adopted M4 mission within the Cosmic Vision science programme of ESA. The...
