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…
Multiwavelength observations of PSR J2021+4026 across a mode change reveal a phase shift in its X-ray emission
M. Razzano, A. Fiori, P. M. Saz Parkinson +6
Context. We have investigated the multiwavelength emission of PSR J2021+4026, the only isolated gamma-ray pulsar known to be variable, which in October 2011 underwent a simultaneou…
The Third Fermi Large Area Telescope Catalog of Gamma-ray Pulsars
David A. Smith, Philippe Bruel, Colin J. Clark +156
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio…
Radio WISSH: tuning on the most luminous quasars in the Universe
Gabriele Bruni, Javier Moldón, Enrico Piconcelli +8
In the past years, the results obtained by the WISSH quasar project provided a novel general picture on the distinctive multi-band properties of hyper-luminous ( e…
Sensitivity of the Cherenkov Telescope Array to TeV photon emission from the Large Magellanic Cloud
The Cherenkov Telescope Array Consortium
A deep survey of the Large Magellanic Cloud at ~0.1-100TeV photon energies with the Cherenkov Telescope Array is planned. We assess the detection prospects based on a model for the…
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 LHAASO PeVatron bright sky: what we learned
Martina Cardillo, Andrea Giuliani
The recent detection of 12 gamma-ray Galactic sources well above E > 100 TeV by the LHAASO observatory has been a breakthrough in the context of Cosmic Ray (CR) origin search. Alth…
XTE J1906+090: a persistent low luminosity Be X-ray Binary
V. Sguera, L. Sidoli, A. J. Bird +1
We present new results from INTEGRAL and Swift observations of the hitherto poorly studied and unidentified X-ray source XTE J1906+090. A bright hard X-ray outburst (luminosity of…
Measuring the Cosmic X-ray Background in 3-20keV with Straylight from NuSTAR
Steven Rossland, Daniel Wik, Brian Grefenstette +13
By characterizing the contribution of stray light to large datasets from the NuSTAR X-ray observatory collected over 2012--2017, we report a measurement of the cosmic X-ray backgro…
The largest bright ULX population in a galaxy: X-ray variability and Luminosity Function in the Cartwheel ring Galaxy
Chiara Salvaggio, Anna Wolter, Andrea Belfiore +1
We analyse all the available Chandra observations of the Cartwheel Galaxy and its compact group, taken between 2001 and 2008, with the main aim of addressing the variability in the…
The first JWST spectrum of a GRB afterglow: No bright supernova in observations of the brightest GRB of all time, GRB 221009A
A. J. Levan, G. P. Lamb, B. Schneider +57
We present JWST and Hubble Space Telescope (HST) observations of the afterglow of GRB 221009A, the brightest gamma-ray burst (GRB) ever observed. This includes the first mid-IR spe…
The peak-flux of GRB 221009A measured with GRBAlpha
Jakub Ripa, Hiromitsu Takahashi, Yasushi Fukazawa +42
The brightest gamma-ray burst ever observed, long-duration GRB 221009A, was detected by GRBAlpha nano-satellite without saturation. We present light curves of the prompt emission i…
Fermi-GBM Discovery of GRB 221009A: An Extraordinarily Bright GRB from Onset to Afterglow
S. Lesage, P. Veres, M. S. Briggs +136
We report the discovery of GRB 221009A, the highest flux gamma-ray burst ever observed by the Fermi Gamma-ray Burst Monitor (GBM). This GRB has continuous prompt emission lasting m…
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-…
