Radio core dominance of Fermi/LAT-detected AGNs
We present a sample of 4388 AGNs with available radio core-dominance parameters-defined as the ratio of the core flux densities to the extended ones, R=S_core_/S_ext._ - which... -
Extragalactic linear polarization meas. agglomeration
In the framework of the Standard Model Extension (SME), we present improved constraints on anisotropic Lorentz invariance and Charge-Parity-Time (CPT) violation by searching for... -
Catalog of short gamma-ray transients
We analyzed the data obtained by the SPI telescope onboard the INTEGRAL observatory to search for short transient events with a duration from 1 ms to a few tens of seconds. An... -
gamma-ray properties of FR-Is and BL Lacs
Our knowledge of Giga-electron volt (GeV) radio galaxies has been revolutionized by the Fermi-LAT Telescope, which provides an excellent opportunity to study the physical... -
Sample of Fermi FSRQs
The location of {gamma}-ray-emitting region in blazars has been an open issue for several decades and is still being debated. We use the Paliya et al. sample of 619... -
Gamma-ray emitting jetted AGN
We considered the fourth catalog of gamma-ray point sources produced by the Fermi Large Area Telescope (LAT) and selected only jetted active galactic nuclei (AGN) or sources... -
Blazars properties
We analyzed the relationship between several basic parameters describing supermassive black holes such as jet power, black hole spin, accretion disk magnetic field, black hole... -
GRB isotropic energy function
Gamma-ray bursts (GRBs) are brief, intense, gamma-ray flashes in the universe, lasting from a few milliseconds to a few thousand seconds. For short gamma-ray bursts (sGRBs) with... -
gamma-ray spectrum for Fermi blazars
The curvature of the {gamma}-ray spectrum in blazars may reflect the intrinsic distribution of emitting electrons, which will further give some information on the possible... -
Sample of Fermi Blazars
We study the {gamma}-ray luminosity and beaming effect for Fermi blazars. Our results are as follows. (i) There are significant correlations between {gamma}-ray luminosity and... -
Doppler factor for a Fermi blazar sample
We selected 457 blazars (193 flat spectrum radio quasars, 61 low-synchrotron peaked blazars, 69 intermediate-synchrotron peaked blazars and 134 high-synchrotron peaked blazars)... -
{gamma}-ray Doppler factor for Fermi blazars
Observations suggest that gamma-ray loud blazars are strongly beamed. The Fermi mission has detected many of blazars, which provide us with a good opportunity to investigate the... -
Radio and {Gamma}-ray of MOJAVE-Fermi AGNs
Within the MOJAVE VLBA programme (Monitoring of Jets in AGN with VLBA Experiments), we have accumulated observational data at 15 GHz for hundreds of jets in gamma-ray bright... -
GRB 141220A light curves
We report the earliest ever detection of optical polarization from a GRB forward shock (GRB 141220A), measured 129.5-204.3s after the burst using the multicolour RINGO3 optical... -
ML approach for GRB detection in AstroSat CZTI
We present a machine learning (ML) based method for automated detection of Gamma-Ray Burst (GRB) candidate events in the range 60-250 keV from the AstroSat Cadmium Zinc... -
Core-collapses supernovae host galaxies
We present a comprehensive study of an unbiased sample of 150 nearby (median redshift, z = 0.014) core-collapse supernova (CCSN) host galaxies drawn from the All-Sky Automated... -
Jet efficiencies and black hole spins in quasars
The mechanisms responsible for the production of relativistic jets from supermassive black holes (SMBHs) accreting at near-Eddington rates are not well understood. Simple... -
GRB hydrogen column densities
It is known that the GRB equivalent hydrogen column density (N_HX_) changes with redshift and that, typically, N_HX_ is greater than the GRB host neutral hydrogen column... -
Comparison between GRB afterglows and AT2017gfo
Multimessenger astronomy received a great boost following the discovery of kilonova (KN) AT2017gfo, the optical counterpart of the gravitational wave source GW170817 associated... -
The 2BIGB gamma-ray blazars catalog
This paper presents the results of a {gamma}-ray likelihood analysis over all the extreme and high synchrotron peak blazars (EHSP and HSP) from the 3HSP catalogue. We...
