The Crab Nebula progenitor: recovering the 1054 AD supernova event as galactic Gamma-ray burst
Costantino Sigismondi, Remo Ruffini
In 1054 AD a daytime star appeared in the constellation of Taurus, for three weeks, and it was reported in various sources from Europe to China/Japan: it was one of the few documen…
GRB 220101A: a most energetic erg long GRB triggered by two supernovae 3.5 seconds apart
R. Ruffini, Y. Aimuratov, L. M. Becerra +10
GRB 220101A is a long GRB, with a total energy exceeding erg with a redshift and one of the largest ever high-quality multi-wavelength observational coverage,…
Selected topics on: 1) proposal of interpreting the Crab supernova with a GRB 2) progress in identifying the seven GRBs episodes 3) the role of Sagittarius A in identifying the dark matter component (the X fermion)
R. Ruffini, C. Sigismondi, Y. Wang +10
As the fiftieth anniversary of our common effort in the field of relativistic astrophysics is approaching, we offer a new look to some of our acquired knowledge in a more complete…
ASIACO: Asiago Spectroscopy and Imaging Atlas of COmets
P. Ochner, F. Manzini, V. Oldani +8
The ASIACO project is an atlas of cometary imaging and spectroscopy obtained from the Asiago Astrophysical Observatory between 2012 and 2024, still ongoing. Up to now, we monitored…
The Great Dimming of the hypergiant star RW Cephei: CHARA Array images and spectral analysis
N. Anugu, F. Baron, D. R. Gies +15
The cool hypergiant star RW Cephei is currently in a deep photometric minimum that began several years ago. This event bears a strong similarity to the Great Dimming of the red sup…
Solstices and Equinoxes in 1703 at the meridian line of St. Maria degli Angeli in Rome, and the stellar aberration of Sirius
Costantino Sigismondi, Silvia Pietroni
The 1703 was the first year of full operation of the meridian line in the Basilica of St. Maria degli Angeli in Rome. The instants of solstices and equinoxes, the \textit{Anni Card…
