The 3HSP catalogue of Extreme & High Synchrotron Peaked Blazars

All new {\gamma}-ray detections are described in the First and Second Brazil ICRANet gamma-ray blazar catalogues (1BIGB & 2BIGB) also taking into account the 4FGL list of {\gamma}-ray sources published by the Fermi large area telescope (Fermi-LAT) team. Expand abstract.

High-energy emission from GRBs: 10 years with Fermi-LAT

Here we present the results of a new systematic search for high-energy emission from the full sample of GRBs detected in 10 years by the Fermi Gamma-Ray Burst Monitor, as well as Swift, AGILE, Integral and IPN bursts, featuring a detection efficiency more than 50\%\ better than previous works, and returning 186 detections...

Physical Inference from the gamma-ray, X-Ray and Optical Time Variability of a Large Sample of Fermi Blazars

We present cross-correlation studies of gamma-ray (0.1-300 GeV), X-ray (0.2-10 keV) and optical (R-band) variability of a sample of 26 blazars during 2008-2016. Expand abstract.

Recent results from the VERITAS multimessenger program

The detection of VHE gamma rays from these sources would not only help in pinpointing an electromagnetic counterpart to the gravitational-wave event, but also enable the study of the relativistic shocks responsible for the high-energy emission. Expand abstract.

Long term multi-wavelength view of the blazar 1ES 1218+304

In this work, we present a multi-wavelength study of the blazar 1ES 1218+304 using near simultaneous observations over 10 years during the period September 1, 2008 to August 31, 2018 (MJD 54710-58361). Expand abstract.
