Outliers from the mainstream: how a massive star can produce a gamma-ray burst
S. Campana, N. Panagia, D. Lazzati +12
It is now recognized that long-duration Gamma-Ray Bursts (GRBs) are linked to the collapse of massive stars, based on the association between (low-redshift) GRBs and (type Ic) core…
The oldest X-ray supernovae: X-ray emission from 1941C, 1959D, 1968D
Roberto Soria, Rosalba Perna
We have studied the X-ray emission from four historical Type-II supernovae (the newly-discovered 1941C in NGC 4631 and 1959D in NGC 7331; and 1968D, 1980K in NGC 6946), using Chand…
The prompt, high resolution spectroscopic view of the "naked-eye" GRB080319B
V. D'Elia, F. Fiore, R. Perna +21
GRB080319B reached 5th optical magnitude during the burst prompt emission. Thanks to the VLT/UVES rapid response mode, we observed its afterglow just 8m:30s after the GRB onset whe…
Optical and Infrared Observations of the X-ray source 1WGA J1713.43949 in the G347.3-0.5 SNR
R. P. Mignani, S. Zaggia, A. De Luca +3
X-ray observations unveiled the existence of enigmatic point-like sources at the centre of young supernova remnants (SNRs). These sources, dubbed Central Compact Objects (CCOs), ar…
X-Ray Eclipse Time Delays in 4U2129+47
E. Bozzo, M. Falanga, A. Papitto +8
4U 2129+47 was discovered in the early 80's and classified as an accretion disk corona source due to its broad and partial X-ray eclipses. The 5.24 hr binary orbital period was inf…
Deep VLT infrared observations of X-ray Dim Isolated Neutron Stars
G. Lo Curto, R. P. Mignani, R. Perna +1
X-ray observations have unveiled the existence of a family of radio-quiet Isolated Neutron Stars whose X-ray emission is purely thermal, hence dubbed X-ray Dim Isolated Neutron Sta…
