The supermassive black hole in the Seyfert 2 galaxy NGC 5252
Alessandro Capetti, Alessandro Marconi, Duccio Macchetto +1
We present results from HST/STIS long-slit spectroscopy of the gas motions in the nuclear region of the Seyfert 2 galaxy NGC 5252. The observed velocity field is consistent with ga…
ESO-VLT optical spectroscopy of BL Lac objects: I. new redshifts
B. Sbarufatti, A. Treves, R. Falomo +3
We report redshift measurements for 12 BL Lacertae objects from a program aimed at obtaining high signal to noise (up to ~ 500) optical spectroscopy of a mixed sample of objects. T…
High energy beta beams without massive detectors
F. Terranova, A. Marotta, P. Migliozzi +1
In this paper, the possibility to exploit a high energy beta beam without massive detectors is discussed. The radioactive ions are boosted up to very high with the neutrino bea…
Super massive black holes in spiral galaxies: HST/STIS observations for 3 new objects
L. Coccato, E. Dalla Bonta', M. Sarzi +3
We present long-slit HST/STIS measurements of the ionized-gas kinematics in the nucleus of three disk galaxies, namely NGC 2179, NGC 4343, NGC 4435. The sample galaxies have been s…
Small x behavior of parton distributions. A study of higher twist effects
Alexei Yu. Illarionov, Anatoly V. Kotikov, Gonzalo Parente
Higher twist corrections to the structure function F_2 at small x are studied for the case of a flat initial condition for the twist-two QCD evolution in the next-to-leading order…
