Near-infrared spectroscopy of extreme BAL QSOs from the QUBRICS bright quasar survey
Guido Cupani, Giorgio Calderone, Pierluigi Selvelli +8
We report on the spectral confirmation of 18 QSO candidates from the "QUasars as BRIght beacons for Cosmology in the Southern hemisphere'' survey (QUBRICS), previously observed in…
Comparing the spectral lag of short and long gamma-ray bursts and its relation with the luminosity
M. G. Bernardini, G. Ghirlanda, S. Campana +14
We investigated the rest frame spectral lags of two complete samples of bright long (50) and short (6) gamma-ray bursts (GRB) detected by Swift. We analysed the Swift/BAT data thro…
There is a short gamma-ray burst prompt phase at the beginning of each long one
G. Calderone, G. Ghirlanda, G. Ghisellini +9
We compare the prompt intrinsic spectral properties of a sample of short Gamma--ray Burst (GRB) with the first 0.3 seconds (rest frame) of long GRBs observed by Fermi/GBM. We find…
The WISE view of the disc-torus connection in z~0.6 Active Galactic Nuclei
Giorgio Calderone, Tullia Sbarrato, Gabriele Ghisellini
We selected all radio-quiet AGN in the latest release of Sloan digital sky survey quasar catalog, with redshift in the range 0.56-0.73. About 4000 (~80%) of these have been detecte…
