Optical variability of jetted AGN
The variability characteristics of jetted active galactic nuclei (AGNs) serve as a powerful diagnostic tool for probing the physical mechanisms underlying accretion processes... -
4FGL very high-energy gamma-ray emitting blazars
Very high-energy (VHE; >100GeV) {gamma}-ray emission originates via some of the most extreme particle acceleration processes in the Universe. Considering beamed active... -
Gamma-ray burst polarization measurements
Despite decades of polarization observations and high significance of polarized {gamma}-ray, X-ray, optical, and radio emissions in gamma-ray bursts (GRBs) accumulating in... -

X-ray catalog and classification of 4FGL-DR4 UGSs
Our survey of the fourth Fermi Large Area Telescope catalog (4FGL) unassociated gamma-ray source regions using the X-Ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT)... -
Multiplets of IceCube alert events
The IceCube Neutrino Observatory publishes "alert events", which are detections of high-energy neutrinos with a moderate-to-high probability of being of astrophysical origin.... -
Fermi LAT Fourth Source Cat. DR4 (4FGL-DR4)
We present an incremental version (4FGL-DR4, for Data Release 4) of the fourth Fermi-LAT catalog containing 7194 gamma-ray sources. Based on the first 14 years of science data... -
VLBI and bright Fermi/LAT sources
A list of 205 {gamma}-ray strong objects was reported recently as a result of a three-month integration with the Large Area Telescope on board the Fermi Gamma-Ray Space... -
The Fermi LAT sky as seen by INTEGRAL/IBIS
In this Letter we present the result of the cross correlation between the fourth INTEGRAL/IBIS soft gamma-ray catalog, in the range 20-100keV, and the Fermi LAT bright source... -
Associations between short GRBs & FRBs
The physical origin of fast radio bursts (FRBs) is still unclear. However, young magnetars associated with short-duration gamma-ray bursts (SGRBs) have been thought to be... -
ZTF LC analysis of Fermi LAT (4LAC-DR3) AGNs
The variability mechanisms from jetted active galactic nuclei (AGNs) are still under debate. Here, the damped random walk (DRW) model, implemented through Gaussian processes... -
X-ray burst pulse obs. from GBM, GECAM & HXMT
SGR J1935+2154 is an extremely active magnetar and the source of the first fast radio burst in the Milky Way, characterized as a magnetar X-ray burst, but whether the temporal... -
Radio-bright/dark GRBs X/radio properties
We analyse two distinct samples of gamma-ray bursts (GRBs), with and without radio afterglow emission. We use an updated sample of 211 GRBs and find, in agreement with previous... -
The gamma/optical flares of 4FGL-DR3 blazars
Using blazar light curves from the optical All-Sky Automated Survey for Supernovae (ASAS-SN) and the {gamma}-ray Fermi-LAT telescope, we performed the most extensive statistical... -
Estimating the peak energy of Swift GRBs
Gamma-ray bursts (GRBs) are among the most energetic explosive phenomena in the universe, and their peak energy (Ep) is a key physical quantity for understanding the prompt... -
Second H.E.S.S. GRB catalogue
Recent observational efforts using imaging atmospheric Cherenkov telescopes (IACTs) have led to firm detections of very-high-energy (VHE) signals from bright gamma-ray bursts... -
GCN VOEvent Streams From Swift-BAT (Burst Alert Telescope)
VOEvent alerts produced from transient detections resulting from observations with the NASA Neil Gehrels Swift Observatory and the Burst Alert Telescope. Events should be... -
GCN VOEvent Streams From Fermi-GBM
VOEvent alerts produced from transient detections resulting from observations with the NASA Fermi Gamma-ray Burst Monitor. Events should be reported within tens to hundreds of...
