Testing particle acceleration in blazar jets with continuous high-cadence optical polarization observations
Ioannis Liodakis, Sebastian Kiehlmann, Alan P. Marscher +44
Variability can be the pathway to understanding the physical processes in astrophysical jets, however, the high-cadence observations required to test particle acceleration models a…
Optical polarimetry study of Lambda-Orionis star-forming region
Sharma Neha, Archana Soam, G. Maheswar
We present an optical polarimetric study of a nearby star-forming region, Lambda-Orionis, to map plane-of-the-sky magnetic field geometry to understand the magnetized evolution of…
Investigation of Rocket Effect in Bright-Rimmed Clouds using Gaia EDR3
Piyali Saha, Maheswar G., D. K. Ojha +2
Bright-rimmed clouds (BRCs) are excellent laboratories to explore the radiation-driven implosion mode of star formation because they show evidence of triggered star formation. In o…
Dust emission, extinction, and scattering in LDN 1642
Mika Juvela, Sharma Neha, Emma Mannfors +3
We study the near-infrared (NIR) scattering in LDN 1642, its correlation with the cloud structure, and the ability of dust models to simultaneously explain sub-millimetre emission,…
Magnetic fields in multiple bright-rimmed clouds in different directions of HII region IC1396 - II
Archana Soam, G. Maheswar, Chang Won Lee +2
Bright-rimmed clouds form on the edges of H II regions affected by the high energy radiation from a central ionizing source. The UV radiation from the ionizing source results in co…
Polarization of seven MBM clouds at high galactic latitude
S. Neha, G. Maheswar, A. Soam +1
We made R-band polarization measurements of 234 stars towards the direction of MBM 33-39 cloud complex. The distance of MBM 33-39 complex was determined as pc using pola…
Flux and polarization variability of OJ 287 during early 2016 outburst
Suvendu Rakshit, C. S. Stalin, S. Muneer +2
The gamma-ray blazar OJ 287 was in a high activity state during December 2015 - February 2016. Coinciding with this high brightness state, we observed this source for photometry on…
Magnetic field structure of IC 63 and IC 59 associated to H II region - Sh 185
A. Soam, G. Maheswar, Chang Won Lee +2
Bright-rimmed clouds (BRCs) are formed at the periphery of HII regions as the radiation from the central star interacts with dense gas. The ionization and resulting compression…
Probing the magnetic fields in L1415 and L1389
A. Soam, Chang Won Lee, Maheswar G. +3
We present the R-band polarimetric results towards two nebulae L1415 and L1389 containing low luminosity stars. Aim of this study is to understand the role played by magnetic field…
Magnetic field geometry of an unusual cometary cloud Gal 110-13
S. Neha, G. Maheswar, A. Soam +2
We carried out optical polarimetry of an isolated cloud, Gal 110-13, to map the plane-of-the-sky magnetic field geometry. The main aim of the study is to understand the most plausi…
