Exploring PSR J0901-4046 as an ultra-slowly rotating neutron star versus a white dwarf
Banibrata Mukhopadhyay, Nirupam Roy, Zenia Zuraiq +2
The source PSR J0901-4046 shows a very long rotational period, of s. In fact, its long period suggests that it could be a white dwarf. We examine the properties of…
The Multi-phase HI of the Milky Way and Nearby Galaxies
Marc-Antoine Miville-Deschênes, J. R. Dawson, Narendra Nath Patra +30
Atomic hydrogen (HI) is the dominant baryonic component of the interstellar medium (ISM) in Milky Way-like galaxies and the reservoir from which molecular clouds and stars ultimate…
Particle Acceleration and Depolarization in the Protostellar jet knots HH 80 and HH 81
A. G. Cheriyan, S. Vig, Nirupam Roy +4
Linearly polarized emission is a powerful tracer of magnetic field geometry and particle acceleration in protostellar jets. We present a polarimetric study of the HH objects HH 80…
First detection of Circular Polarization in radio continuum towards a Massive Protostar
A. G. Cheriyan, S. Vig, Nirupam Roy +4
Polarization measurements provide strong constraints on magnetic fields in star-forming systems. While magnetic field estimates of a few kiloGauss (kG) have been obtained near the…
The temperature of the neutral Interstellar Medium in the Galaxy
Narendra Nath Patra, Nirupam Roy
Atomic Hydrogen-21 cm transition (HI) is an excellent tracer to study and understand the properties of the atomic gas in the Galaxy. Using the Westerbork Synthesis Radio Telescope…
Shock-driven synchrotron radio emission from the 2021 outburst of RS Ophiuchi
A. J. Nayana, G. C. Anupama, Nirupam Roy +4
We present low-frequency radio observations of the Galactic symbiotic recurrent nova RS Ophiuchi during its 2021 outburst. The observations were carried out with the upgraded Giant…
Multiphase Neutral Interstellar Medium: Analyzing Simulation with H I 21cm Observational Data Analysis Techniques
Soumyadeep Bhattacharjee, Nirupam Roy, Prateek Sharma +2
Several different methods are regularly used to infer the properties of the neutral interstellar medium (ISM) using atomic hydrogen (H I) 21cm absorption and emission spectra. In t…
