A magnetar giant flare in the nearby starburst galaxy M82
Sandro Mereghetti, Michela Rigoselli, Ruben Salvaterra +32
Giant flares, short explosive events releasing up to 10 erg of energy in the gamma-ray band in less than one second, are the most spectacular manifestation of magnetars, you…
XMM-Newton and INTEGRAL observations of the bright GRB 230307A : vanishing of the local absorption and limits on the dust in the Magellanic Bridge
Sandro Mereghetti, Michela Rigoselli, Ruben Salvaterra +2
230307A is the second brightest gamma ray burst detected in more than 50 years of observations and is located in the direction of the Magellanic Bridge. Despite its long duration,…
Timing the X-ray pulsating companion of the hot-subdwarf HD 49798 with NICER
Michela Rigoselli, Davide De Grandis, Sandro Mereghetti +1
HD 49798 is a hot subdwarf of O spectral type in a 1.55 day orbit with the X-ray source RX J0648.0-4418, a compact object with spin period of 13.2 s. We use recent data from the NI…
The power of the rings: the GRB 221009A soft X-ray emission from its dust-scattering halo
Andrea Tiengo, Fabio Pintore, Beatrice Vaia +11
GRB 221009A is the brightest gamma-ray burst (GRB) ever detected and occurred at low Galactic latitude. Owing to this exceptional combination, its prompt X-ray emission could be de…
X-ray nondetection of PSR J0250+5854
C. M. Tan, M. Rigoselli, P. Esposito +1
We conducted a deep XMM$\unicode{x2013}$Newton observing campaign on the 23.5-s radio pulsar PSR J0250+5854 in order to better understand the connection between long-period, radio-…
