On the Size of HII Regions around High Redshift Quasars
A. Maselli, S. Gallerani, A. Ferrara +1
We investigate the possibility of constraining the ionization state of the intergalactic medium (IGM) close to the end of reionization (z ~ 6) by measuring the size of the HII regi…
Opening a New Window to Fundamental Physics and Astrophysics: X-ray Polarimetry
E. Costa, R. Bellazzini, P. Soffitta +25
An extensive theoretical literature predicts that X-ray Polarimetry can directly determine relevant physical and geometrical parameters of astrophysical sources, and discriminate b…
Optical properties of the NGC 5328 group of galaxies
R. Gruetzbauch, F. Annibali, A. Bressan +4
We present the results of a photometric and spectroscopic study of seven members of the NGC 5328 group of galaxies, a chain of galaxies spanning over 200 kpc (H_0 = 70 km/s/Mpc). W…
The peak luminosity - peak energy correlation in GRBs
G. Ghirlanda, G. Ghisellini, C. Firmani +2
We derive the peak luminosity - peak energy (L_iso - E_peak) correlation using 22 long Gamma-Ray Bursts (GRBs) with firm redshift measurements. We find that its slope is similar to…
Short-Bright GRBs: spectral properties
G. Ghirlanda, G. Ghisellini, A. Celotti
We study the spectra of short-bright GRBs detected by BATSE and compare them with the average and time resolved spectral properties of long-bright bursts. We confirm that short eve…
The spectra of short Gamma-Ray Bursts
G. Ghirlanda, G. Ghisellini, A. Celotti
We present the results of the spectral analysis of a sample of short bright --ray bursts (GRB) detected by BATSE and compare them with the average and time resolved spectral pro…
