The Remarkable Predictive Power of Infrared Data of Blazars
The Astrophysical JournalBlazars are the brightest and most abundant persistent sources in the extragalactic γ -ray sky. Due to their significance, they are often observed across various energy bands, where the data of which can be used to explore potential correlations between ...

Revealing the Variation Mechanism of ON 231 via the Two-component Shock-in-jet Model
The Astrophysical JournalThe variation mechanism of blazars is a long-standing unresolved problem. In this work, we present a scenario to explain diverse variation phenomena for ON 231, where the jet emissions are composed of the flaring and the less variable components (most ...

Properties and Possible Physical Origins of γ-Ray Emission in Extreme Synchrotron Blazars
The Astrophysical JournalExtreme synchrotron blazars, characterized by a first peak in their broadband spectral energy distributions (SEDs) at frequencies exceeding 10 ^17 Hz, often exhibit a second peak beyond 1 TeV.

Constraining the PG 1553+113 Binary Hypothesis: Interpreting Hints of a New, 22 yr Period
The Astrophysical JournalPG 1553+113 is a well-known blazar exhibiting evidence of a ∼2.2 yr quasiperiodic oscillation (QPO) in the radio, optical, X-ray, and γ -ray bands. Since QPO mechanisms often predict multiple QPOs, we search for a second QPO in its historical optical ...
