This review provides an overview of recent advances in multi-wavelength and multi-
messenger observations of blazars, the current status of theoretical models for blazar …

Almost 10 yr of γ-ray observations with the Fermi Large Area Telescope have revealed
extreme γ-ray outbursts from flat spectrum radio quasars (FSRQs), temporarily making these …

Spinning black holes in the centres of galaxies can release powerful magnetised jets. When
the jets are observed at angles of less than a few degrees to the line-of-sight, they are called …

The recent hint of correlated γ-ray and neutrino emission from the blazar TXS 0506+ 056
has renewed interest in blazars as the source of high-energy neutrinos, in which the …

In this work, a time-dependent modelling is developed to study the emission properties of
blazars in the low state. Motivated by various observations, we speculate and assume that …

We present periodicity search analyses on the γ-ray light curve of the TeV blazar PKS 1510-
089 observed by the Fermi Large Area Telescope. We report the detection of two transient …

Various attempts have been made in the literature at describing the origin and the physical
mechanisms behind flaring events in blazars with radiative emission models, but detailed …

BL Lacertae, the prototype of the BL Lacertae (BL Lac) category of blazars, underwent a
giant γ-ray flare in April 2021. The Large Area Telescope (LAT) on board the Fermi Gamma …

We present long-term multiwavelength observations of blazar CTA 102 (= 1.037). Detailed
temporal and spectral analyses of γ-ray, X-ray, and UV/optical data observed by Fermi-LAT …

In this work, we report periodicity search analyses in the gamma-ray light curve of the blazar
S4 0954+ 658 in monitoring undertaken by the Fermi Large Area Telescope. Four analytical …
