Spitzer 24 micron imaging of Faint Radio Sources in the FLSv: a new radio-loud, Mid-IR/optically obscured population?
M. Orienti, M. A. Garrett, C. Reynolds +1
Data from the Spitzer Space Telescope (the First Look Survey - FLS) have recently been made public. We have compared the 24 micron images with very deep WSRT 1.4 GHz observations (…
A detailed study of the nuclear region of Mrk 273
M. Bondi, D. Dallacasa, M. A. Peerez Torres +1
We present 5 GHz EVN+MERLIN observations of the nuclear region of the ultra luminous infrared galaxy Mrk 273. These observations confirms the detection, on the mas scale, of two re…
VLBI polarimetric observations of 3C147
A. Rossetti, F. Mantovani, D. Dallacasa
We present multi-frequency VLBI observations of the Compact Steep-spectrum Quasar 3C147 (0538+498) made with the VLBA at the four frequencies in the available 5 GHz band and at 8.4…
Measurement of the J/Psi Meson and b-Hadron Production Cross Sections in ppbar Collisions at sqrt s = 1960 GeV
D. Acosta, CDF Collaboration
We present a new measurement of the inclusive and differential production cross sections of mesons and -hadrons in proton-antiproton collisions at GeV. The…
Small x evolution: BFKL vs Dipole Picture
G. P. Vacca
The relation between the two approaches is discussed both in the linear and nonlinear regimes. It is connected to the gauge invariance and Moebius symmetry in LL perturbative QCD.…
An optimal filter for the detection of galaxy clusters through weak lensing
M. Maturi, M. Meneghetti, M. Bartelmann +2
We construct a linear filter optimised for detecting dark-matter halos in weak-lensing data. The filter assumes a mean radial profile of the halo shear pattern and modifies that sh…
Small-scale systems of galaxies. II. Properties of the NGC 4756 group of galaxies
R. Gruetzbauch, B. Kelm, P. Focardi +3
We present results from a study of the NGC 4756 group which is dominated by the elliptical galaxy NGC 5746. The characteristics of the group are investigated through (a) the detail…
The two sided parsec scale structure of the Low Luminosity Active Galactic Nucleus in NGC 4278
G. Giovannini, M. Giroletti, G. B. Taylor
We present new Very Long Baseline Interferometry observations of the LINER galaxy NGC 4278 with a linear resolution of < 0.1 pc. Our radio data reveal a two sided structure, with s…
CPT-conserving Hamiltonians and their nonlinear supersymmetrization using differential charge-operators C
B. Bagchi, A. Banerjee, E. Caliceti +4
A brief overview is given of recent developments and fresh ideas at the intersection of PT and/or CPT-symmetric quantum mechanics with supersymmetric quantum mechanics (SUSY QM). W…
Two-Loop QCD Corrections to the Heavy Quark Form Factors: Axial Vector Contributions
W. Bernreuther, R. Bonciani, T. Gehrmann +4
We consider the Z Q Qbar vertex to second order in the QCD coupling for an on-shell massive quark-antiquark pair and for arbitrary momentum transfer of the Z boson. We present clos…
Cluster mergers and non-thermal phenomena: expectations from a statistical magneto-turbulent model
R. Cassano, G. Brunetti
The most important evidences for non-thermal phenomena in galaxy clusters comes from the spectacular synchrotron radio emission diffused over Mpc scale observed in a growing number…
Laboratory and space spectroscopy of DCO+
Paola Caselli, Luca Dore
The rotational spectra of DCO+ and its two isotopomers D{13}^CO+ and DC{18}^O+, produced in a negative glow discharge cell, have been recorded in the 137-792 GHz region, which incl…
Pomeron Vertices in Perturbative QCD in Diffractive Scattering
J. Bartels, M. Braun, G. P. Vacca
We analyse the momentum space triple Pomeron vertex in perturbative QCD. In addition to the standard form of this vertex which is used in the context of total cross-sections at hig…
Closed geodesics and billiards on quadrics related to elliptic KdV solutions
Simonetta Abenda, Yuri N. Fedorov
We consider algebraic geometrical properties of the integrable billiard on a quadric Q with elastic impacts along another quadric confocal to Q. These properties are in sharp contr…
Occurence and Luminosity Functions of Giant Radio Halos from Magneto-Turbulent Model
Rossella Cassano, Gianfranco Brunetti, Giancarlo Setti
We calculate the probability to form giant radio halos (~ 1 Mpc size) as a function of the mass of the host clusters by using a Statistical Magneto-Turbulent Model (Cassano & Brune…
Polarization in CSS/GPS radio sources
D. Dallacasa
The polarisation properties of the intrinsically small (< 20 kpc) radio sources are briefly discussed. At centimetric and decimetric wavelengths, substantial polarised emission is…

L. Foschini, M. Chiaberge, P. Grandi +10
The analysis of an INTEGRAL AO2 observation of the error contours of the EGRET source 3EG J1621+8203 is presented. The only source found inside the error contours for energies betw…
The two sided parsec scale structure of the Low Luminosity Active Galactic Nucleus in NGC 4278

The Ages of Elliptical Galaxies from Mid-Infrared Emission
Pasquale Temi, William G. Mathews, Fabrizio Brighenti
The mid-infrared (10-20 um) luminosity of elliptical galaxies is dominated by the integrated emission from circumstellar dust in red giant stars. As a single stellar population evo…
Quantum Variance and Ergodicity for the baker's map
