Internal Structure, Not Environment, Shapes Metallicity Gradients in Low-Mass Galaxies from MaNGA
Anuroop Dasgupta, Namrata Roy, Saumyadip Samui +2
Dwarf and low-mass galaxies are highly sensitive to stellar feedback and gas flows, yet their spatially resolved gas-phase metallicity remains poorly characterised. We measure radi…
Dynamic Accretion Disk-Corona Connection and Broad Fe K Variability in Mrk 766 Revealed by Time-Resolved High Resolution X-Ray Spectroscopic Analysis
Ayon Mondal, Tathagata Saha, Arijit Sar +1
We present a multi-epoch, primarily X-ray study of the narrow-line Seyfert 1 (NLSy1) galaxy Mrk~766 by combining archival \textit{XMM-Newton} observations spanning nearly two decad…
Multi-zone Modeling of Blazar Jets: Constraints from GeV-Optical Correlation and Short-Timescale Variability
Arit Bala, Kaustav Mitra, Ritaban Chatterjee
We have developed a multi-zone model of blazar jet emission, in which the emission region contains many cells with individual magnetic fields and electron energy distributions. Non…
Location of a Sample of GeV and Optical Outbursts in the Jets of Blazars
Maitreya Kundu, Arit Bala, Saugata Barat +1
The exact location of the -ray emitting region in blazar jets has long been a matter of debate. However, the location has important implications about the emission processes, ge…
Sub-Day Timescale X-ray Spectral Variability of the TeV Blazars Mrk 421 and 1ES 1959+650
Susmita Das, Ritaban Chatterjee
We present X-ray spectra ( keV) of two high synchrotron-peaked blazars Mrk 421 and 1ES 1959+650 from simultaneous observations by the SXT and LAXPC instruments onboard \tex…
Accretion Disc-Jet Decomposition from the Optical-Near Infrared Monitoring of Fermi Blazars
Garima Rajguru, Ritaban Chatterjee
We study the variability of the thermal (accretion disc) and non-thermal (jet) emission of thirteen flat spectrum radio quasars in the optical and near infrared (OIR) regime using…
