Fermi-Large Area Telescope Detection of Very High Energy (>100 GeV) Emission from Compton-Dominated Blazars
P N Naseef Mohammed, Vaidehi S. Paliya, C D Ravikumar
The observation of broad emission lines in the optical spectra of flat-spectrum radio quasars (FSRQs) suggests radiatively efficient accretion powering these objects. In such broad…
The long-term optical flux variations of Compact Symmetric Objects
Subhashree Swain, Vaidehi S. Paliya, D. J. Saikia +4
Compact Symmetric Objects (CSOs) are a distinct category of jetted active galactic nuclei (AGN) whose optical variability characteristics have not been well investigated. We presen…
Deciphering the Multi-Wavelength Flares of the Most Distant Very High-Energy (>100 GeV) Gamma-ray Emitting Blazar
P N Naseef Mohammed, T. Aminabi, C. Baheeja +3
This study analyzes the multi-wavelength flaring activity of the distant flat spectrum radio quasar (FSRQ) OP 313 (z=0.997) during November 2023 to March 2024, using data from Ferm…
Signature of Particle Diffusion on the X-ray Spectra of the blazar Mkn 421
C. Baheeja, S. Sahayanathan, F. M. Rieger +1
The curvature in blazar spectrum has the potential to understand the particle dynamics in jets. We performed a detailed analysis of simultaneous Swift-XRT (0.3-10 keV) and NuSTAR (…
Gamma-ray variability and multi-wavelength insights into the unprecedented outburst from 4C 31.03
Aminabi Thekkoth, Baheeja C, S Sahayanathan +1
The blazar 4C 31.03 recently underwent a major gamma-ray outburst at the beginning of 2023 after a prolonged quiescent phase. Fermi-LAT reported a daily average flux of 5x10^-6 phs…
Connections between Central Intensity Ratio and hot gas properties of early-type galaxies
K T Vinod, C Baheeja, C D Ravikumar
We report strong connections between central intensity ratio (CIR) and hot gas properties of Early-type galaxies (ETGs) in the nearby () Universe. We find new strong…
