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...
Z-Z' mixing in SU(3)_C X SU(3)_L X U(1)_X models with beta arbitrary
We perform a chi ^{2} fit at 95% CL to obtain model-dependent bounds to Z-Z' mixing angle theta and Z_2-mass in the framework of SU(3)_C X SU(3)_L X U(1)_X...
z=1-3 ULIRGs from the Spitzer SWIRE survey (Berta+, 2007)
We present Keck/LRIS optical spectroscopy of 35 z>=1.4 luminous IR galaxies in the Spitzer Wide-area Infra-Red Extragalactic survey (SWIRE) northern fields...
The next generation of space- and ground-based spectropolarimeters demands new diagnostic tools capable of fast (ideally real-time) and reliable interpretation...
Zeeman Effect in Sulfur Monoxide: a Probe to Observe Magnetic Fields in Star Forming Regions?
Magnetic fields play a fundamental role in star formation processes and the best method to evaluate their intensity is is to measure the Zeeman effect of atomic...
