>40MeV proton intensities from 43yr near Earth obs.
We analyze periods with elevated >40MeV proton intensities observed near Earth over a time span of 43yr (1973-2016) that coincide with the passage of interplanetary (IP)... -
Rest-frame parameters of short and long GRBs
The intrinsic statistical properties and correlations of short gamma-ray bursts (SGRBs) have not been fully determined, due to the limitations of observations. In this paper, we... -
Pulses from Fermi-GBM gamma-ray bursts
We perform a detailed analysis of broad pulses in bright gamma-ray bursts (GRBs) to understand the evolution of GRB broad pulses. Using the temporal and spectral properties, we... -
Multiwavelength follow-up obs. of GRB 221009A
GRB 221009A (z=0.151) is one of the closest known long {gamma}-ray bursts (GRBs). Its extreme brightness across all electromagnetic wavelengths provides an unprecedented... -
Fermi jetted AGN with reliable redshift
We collect a large sample with a reliable redshift detected by the Fermi satellite after 10yr of data (4FGL-DR2), including blazars, gamma-ray narrow-line Seyfert 1 galaxies... -
Combined radio Multi-Survey Cat. (MSC) of 4FGL
Approximately one-third of existing {gamma}-ray sources identified by the Fermi Gamma-Ray Space Telescope are considered to be unassociated, with no known counterpart at other... -
FSRQs & BL Lac objects from 4FGL blazar candidates
Among the ~2157 unassociated sources in the third data release (DR3) of the fourth Fermi catalog, ~1200 were observed with the Neil Gehrels Swift Observatory pointed... -
Short GRB host galaxies. I. opt-NIR imaging
We present a comprehensive optical and near-infrared census of the fields of 90 short gamma-ray bursts (GRBs) discovered in 2005-2021, constituting all short GRBs for which host... -
GRB 180618A light curves
The contemporaneous detection of gravitational waves and gamma rays from GW170817/GRB 170817A, followed by kilonova emission a day after, confirmed compact binary neutron star... -
SED, optical & gamma-ray parameters for 656 blazars
It is known that the blazar jet emissions are dominated by nonthermal radiation, while the accretion disk jets are normally dominated by thermal emission. In this work,... -
LAT Gamma-ray spectra of RS Oph 2021 nova
We report the Fermi LAT {gamma}-ray detection of the 2021 outburst of the symbiotic recurrent nova RS Ophiuchi. In this system, unlike classical novae from cataclysmic binaries,... -
IceCube's neutrinos with 4FGL, 2SXPS & CRATES data
The origin of astrophysical high-energy neutrinos detected by the IceCube Neutrino Observatory remains a mystery to be solved. In this paper we search for neutrino source... -
4FGL sources with sp. breaks between 50MeV-1GeV
Cosmic rays are mostly composed of protons accelerated to relativistic speeds. When those protons encounter interstellar material, they produce neutral pions, which in turn... -
LBT/MODS spectrum of the host galaxy of GRB 200826A
Gamma-ray bursts (GRBs) are classified into long and short events. Long GRBs (LGRBs) are associated with the end states of very massive stars, while short GRBs (SGRBs) are... -
Temporal analysis of GRB precursors in Swift-BAT cat.
We select 52 long gamma-ray bursts (GRBs) that have precursor activity in the third Swift-BAT catalog. Each episode shown in both the precursors and the main bursts is fitted by... -
r-band LC of the millisecond pulsar PSR J1555-2908
We report the discovery of PSR J1555-2908, a 1.79ms radio and gamma-ray pulsar in a 5.6hr binary system with a minimum companion mass of 0.052M_{sun}_. This fast and energetic... -
Fermi-LAT-detected blazars fundamental parameters
Aiming to delineate the physical framework of blazars, we present an effective method to estimate four important parameters based on the idea proposed by Becker & Kafatos... -
Fermi blazar jet properties
The origin of jets is one of the most important issues concerning active galactic nuclei, yet it has remained obscure. In this work, we made use of information from emission... -
The 2nd AGILE MCAL GRB cat.: 13yr of observations
We present the results of a systematic search and analysis of GRBs detected by the Astrorivelatore Gamma ad Immagini LEggero (AGILE) MiniCALorimeter (MCAL; 0.4-100MeV) over a... -
Radio afterglow emission of GRBs
Gamma-ray burst (GRB) afterglow emission can be observed from sub-TeV to radio wavelengths, though only 6.6% of observed GRBs present radio afterglows. We examine GRB radio...
