Metrewave Galactic Plane with the uGMRT (MeGaPluG) Survey: Lessons from the Pilot Study
Rohit Dokara, Nirupam Roy, Karl Menten +7
Context. The advent of wide-band receiver systems on interferometer arrays enables one to undertake high-sensitivity and high-resolution radio continuum surveys of the Galactic pla…
Towards -cm intensity mapping at with uGMRT using the tapered gridded estimator III: Foreground removal
Khandakar Md Asif Elahi, Somnath Bharadwaj, Srijita Pal +8
Neutral hydrogen (HI) -cm intensity mapping (IM) is a promising probe of the large-scale structures in the Universe. However, a few orders of magnitude brighter foregrounds obs…
The GMRT archive atomic gas survey -- II. Mass modelling and dark matter halo properties across late-type spirals
Prerana Biswas, Veselina Kalinova, Nirupam Roy +2
Studying the kinematics and mass modelling of galaxies from HI 21 cm data provides valuable insights into the properties of both the baryonic components and the dark matter halo in…
The magnetic fields around the cometary globules, L328, L323 and L331
Siddharth Kumar, Archana Soam, Nirupam Roy
This work presents the magnetic field geometry in a complex of three cometary (with head-tail morphology) globules, namely LDN 323, LDN 328, and LDN 331, using R-band polarization…
Lepto-hadronic interpretation of 2021 RS Ophiuchi nova outburst
Agnibha De Sarkar, Nayana A. J., Nirupam Roy +2
Very high energy (VHE; 100 GeV E 100 TeV) and high energy (HE; 100 MeV E 100 GeV) gamma-rays were observed from the symbiotic recurrent nova RS Ophiuchi (RS O…
Towards -cm intensity mapping at with uGMRT using the tapered gridded estimator II: Cross-polarization power spectrum
Kh. Md. Asif Elahi, Somnath Bharadwaj, Abhik Ghosh +8
Neutral hydrogen () -cm intensity mapping (IM) offers an efficient technique for mapping the large-scale structures in the universe. We introduce the 'Cross' Tapered G…
