Source region of the 2003 November 18 CME that led to the strongest magnetic storm of cycle 23
N. Srivastava, S. Mathew, R. Louis +1
The super-storm of November 20, 2003 was associated with a high speed coronal mass ejection which originated in the NOAA AR 10501 on November 18. This coronal mass ejection had sev…
Orbital Phase Spectroscopy of four High Mass X-ray Binary Pulsars to Study the Stellar Wind of the Companion
Sachindra Naik, Uddipan Mukherjee, Biswajit Paul +1
Our work focuses on a comprehensive orbital phase dependent spectroscopy of the four High Mass X-ray Binary Pulsars (HMXBPs) 4U 1538-52, GX 301-2, OAO 1657-415 & Vela X-1. We hereb…
An explicit realization of fractional statistics in one dimension
S. Sree Ranjani, P. K. Panigrahi, A. K. Kapoor +1
An explicit realization of anyons is provided, using the three-body Calogero model. The fact that in the coupling domain, , the angular spectrum can have a band structure…
Near Infrared Observations of the novae V2491 Cygni and V597 Puppis
Sachindra Naik, D. P. K. Banerjee, N. M. Ashok
We present results obtained from near-infrared JHK spectroscopic observations of novae V2491 Cyg and V597 Pup in the early declining phases of their 2007 and 2008 outbursts respect…
Renormalization group evolution of neutrino masses and mixing in the Type-III seesaw mechanism
Joydeep Chakrabortty, Amol Dighe, Srubabati Goswami +1
We consider the standard model extended by heavy right handed fermions transforming as triplets under SU(2), which generate neutrino masses through the Type-III seesaw mechanis…
Neutrino Dark Energy in Grand Unified Theories
Jitesh R. Bhatt, Pei-Hong Gu, Utpal Sarkar +1
We studied a left-right symmetric model that can accommodate the neutrino dark energy (\nd) proposal. Type III seesaw mechanism is implemented to give masses to the neutrinos. Afte…
