Intrinsic spectra and energetics of BeppoSAX Gamma-Ray Bursts with known redshifts

We present the main results of a study of spectral and energetics properties of twelve gamma-ray bursts (GRBs) with redshift estimates. All GRBs in our sample were detected by BeppoSAX in a broad…

Gaia Data Release 2

Context. The second data release of the Gaia mission (DR2) includes an advance catalogue of variable stars. The classifications of these stars are based on sparse photometry from the first 22 months…

Gaia Data Release 2

TLDR
The dramatic improvement brought by Gaia DR2 astrometry of SSOs is demonstrated by comparisons to the archive data and by preliminary tests on the detection of subtle non-gravitational effects.

The high energy instrument PDS on-board the BeppoSAX X{ray astronomy satellite

BeppoSAX/PDS experiment is one of four narrow eld instruments of the BeppoSAX payload, that also includes two wide eld cameras. The goal of PDS is to extend the energy range of BeppoSAX to hard…

Identification of a host galaxy at redshift z = 3.42 for the γ-ray burst of 14 December 1997

Knowledge of the properties of γ-ray bursts has increased substantially following recent detections of counterparts at X-ray, optical and radio wavelengths. But the nature of the underlying physical…

Gaia Data Release 2

Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and homogeneity of both astrometry…

An unusual supernova in the error box of the γ-ray burst of 25 April 1998

The discovery of afterglows associated with γ-ray bursts at X-ray, optical and radio wavelengths and the measurement of the redshifts of some of these events, has established that γ-ray bursts lie at…

Discovery of an X-ray afterglow associated with the γ-ray burst of 28 February 1997

Establishing the nature of γ-ray bursts is one of the greatest challenges in high-energy astrophysics. The distribution of these bursts is isotropic across the sky, but inhomogeneous in space, with a…

An optical supernova associated with the X-ray flash XRF 060218

TLDR
The data, combined with radio and X-ray observations, suggest that XRF 060218 is an intrinsically weak and soft event, rather than a classical GRB observed off-axis, which extends the GRB–supernova connection to X-rays flashes and fainter supernovae, implying a common origin.
