AGILE detection of transient γ-ray emission from the region of the supergiant fast X-ray transient source IGR J17354-3255

Andrea Bulgarelli, Gabriele Panebianco, Vito Sguera +16

Context. On April 14, 2009, the AGILE satellite detected a γ-ray flare from an unknown transient source. Subsequent X-ray follow-up observations with Swift and INTEGRAL identified…

Insights from the first flaring activity of a high-synchrotron-peaked blazar with X-ray polarization and VHE gamma rays

MAGIC Collaboration, K. Abe, S. Abe +250

We study a flaring activity of the HSP Mrk421 that was characterized from radio to very-high-energy (VHE; E TeV) gamma rays with MAGIC, Fermi-LAT, Swift, XMM-Newton and sever…

Insights into the broad-band emission of the TeV blazar Mrk 501 during the first X-ray polarization measurements

S. Abe, J. Abhir, V. A. Acciari +260

We present the first multi-wavelength study of Mrk 501 including very-high-energy (VHE) gamma-ray observations simultaneous to X-ray polarization measurements from the Imaging X-ra…

AGILE observations of a sample of repeating Fast Radio Burst sources

Claudio Casentini, Francesco Verrecchia, Marco Tavani +2

Fast Radio Bursts are millisecond-duration bursts originating from distant sources. They are classified into two categories: non-repeating FRBs, which manifest as singular events,…

Multi-wavelength study of OT 081: broadband modelling of a transitional blazar

MAGIC Collaboration, H. Abe, S. Abe +270

OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…

AGILE gamma-ray detection of the exceptional GRB 221009A

M. Tavani, G. Piano, A. Bulgarelli +47

Gamma-ray emission in the MeV-GeV range from explosive cosmic events is of invaluable relevance to understanding physical processes related to the formation of neutron stars and bl…
