Frame Dependence of the Pair Contribution to the Pion Electromagnetic Form Factor in a Light-Front Approach
J. P. B. C. de Melo, T. Frederico, E. Pace +1
The frame dependence of the pair-term contribution to the electromagnetic form factor of the pion is studied within the Light Front approach. A symmetric ansatz for the pion Bethe-…
NGC1866: New analysis from HST-WFPC2 observations of the inner regions
E. Di Carlo, G. Raimondo, E. Brocato +2
We report new results on the LMC globular cluster NGC 1866 obtained by analyzing F555W and F814W images from WFPC2@HST. On the basis of the CMD we derive information on the cluster…
Some clues on the tilt of the Horizontal Branches in metal-rich clusters
G. Raimondo, V. Castellani, S. Cassisi +2
We discuss some clues on the large tilt observed in the Horizontal Branch of the metal-rich galactic globular clusters NGC 6388 and NGC 6441. This not yet understood feature is inv…
Surface Brightness Fluctuations: a theoretical point of view
M. Cantiello, G. Raimondo, E. Brocato +1
We present new theoretical evaluations of optical and near-IR Surface Brightness Fluctuations (SBF) magnitudes for single-burst stellar populations in the age range t=5-15 Gyr and…
The Far Ultraviolet Spectroscopic picture of the Missing Baryons in the Local Group
F. Nicastro, A. Zezas, M. Elvis +6
The number of detected baryons in the low-redshift Universe (z < 1) is far small er than the corresponding number of baryons observed at higher redshift. According to hydrodynamica…
XMM-Newton and Wide Field Optical Imaging to crack the mystery of unidentified gamma-ray sources
P. A. Caraveo, A. De Luca, N. La Palombara +5
The limited angular resolution of gamma-ray telescopes prevents the straight identification of the majority of the sources detected so far. While the only certified galactic gamma-…
