Young and very young stars in NGC 3372, the Carina Nebula
Results are presented of a large-scale imaging photometric study of the stellar population in the northern part of NGC 3372 with a wavelength coverage from 0.33...
Young Kinematically Decoupled Components in Early-Type Galaxies
We present results from a series of follow-up observations of a subsample of the representative SAURON survey elliptical (E) and lenticular (S0) galaxies using...
Young Stellar Objects in Gy 2-18 (IRAS 05439+3035)
We present the results of optical and near-IR spectra and mid-infrared images of the star-forming region Gy 2-18, which is associated with IRAS 05439+3035.
Young stellar populations from NUV spectroscopy in massive early-type galaxies
Massive early-type galaxies (ETGs) are mainly populated by old stars that dominate the optical spectral range. We analyse optical and near-ultraviolet (NUV)...
The atlas presents medium-resolution mid-infrared spectra of low- and intermediate mass pre-main sequence objects obtained by the ISOPHOT-S spectrophotometer of...
Z physics effects of an additional non-sequential bottom quark
We analyze the Zff vertex in the framework of models that add a new bottom quark in a non-sequential way and we evaluate the tree level contribution to the LEP...
