  • Jena, Partha Sarathi; Bhushan, Ravi; Shivam, Ajay; Bharti, Nisha; Sudheer, A. K. (Elsevier, 2022-01)
    The advent of Accelerator Mass Spectrometer (AMS) enhanced the application of meteoric 10Be (half-life of 1.39 Ma) as a tracer for understanding earth surface processes on thousand to million-year time scales. However, for ...
  • Coleppa, Baradhwaj; Sarkar, Agnivo (Cornell University Library, 2020-11)
    We discuss the structure of a model with an extended gauge symmetry group SU(2)�SU(2)�U(1) with a correspondingly rich Electroweak Symmetry Breaking structure. In spite of the additional scalar degrees of freedom in the ...
  • Hati, Chandan; Deppisch, Frank F.; Patra, Sudhanwa; Sarkar, Utpal; Valle, Jose W. F. (Elsevier, 2016-11)
    We consider the possibility of grand unification of the SU(3)c⊗SU(3)L⊗U(1)X model in an SU(6) gauge unification group. Two possibilities arise. Unlike other conventional grand unified theories, in SU(6) one can embed the ...

  • Dey, Ujjal Kumar; Mohanty, Subhendra; Tomar, Gaurav (Cornell University Library, 2015-12)
    We explain the 750 GeV diphoton resonance in the context of the dark left-right symmetric model. A global symmetry in this model, stabilizes the dark matter and ensures that the scalar couples only to gluons and photons. ...
  • Dey, Ujjal Kumar; Mohanty, Subhendra; Tomar, Gaurav (Elsevier, 2016-05)
    We explain the 750 GeV750 GeV diphoton resonance in the context of the dark left-right symmetric model. A global symmetry in this model, stabilizes the dark matter and ensures that the scalar couples dominantly to gluons ...
  • Ali, Ahmed Farag; Faizal, Mir; Majumder, Barun (arXiv, Cornell University Library, 2014-06)
    We will argue that the divergence in time for the asymptotic observer occurs because of specifying the position of the Horizon beyond the Planck scale. In fact, a similar divergence in time will also occur for an in-going ...

  • Jana, Arghajit; Ricci, Claudio; Naik, Sachindra; Tanimoto, Atsushi; Kumari, Neeraj; Chang, Hsiang-Kuang; Nandi, Prantik; Chatterjee, Arka; Safi-Harb, Samar (Cornell University Library, 2022-03)
    We present a detailed study of the highly obscured active galaxy NGC 4507, performed using four Nuclear Spectroscopic Telescope Array (NuSTAR) observations carried out between May and August in 2015 (~ 130 ks in total). ...

  • Upadhyay, Ramesh V.; Parekh, Kinnari; Banerjee, A.; Kumar, Kranti (2010-08-20)
    It is shown that variation of the third order ac-susceptibility as a function of measuring field and frequency lead to distinguish between superparamagnetic and spin glass like ordering in the rare earth substituted magnetic ...
  • Mondal, Shanwlee Sow; Sarkar, Aveek; Vaidya, Bhargav; Mignone, Andrea (Cornell University Library, 2021-10)
    Interplanetary Coronal Mass Ejection (ICME) shocks are known to accelerate particles and contribute significantly to Solar Energetic Particle (SEP) events. We have performed Magnetohydrodynamic-Particle in Cell (MHD-PIC) ...

    We present the results obtained from detailed timing and spectral studies of a black hole candidate MAXI~J1813-095 using (it Swift}, (it NICER), and (it NuSTAR) observations during its 2018 outburst. The timing behaviour ...

  • Suthar, Kuldeep; Roy, Arko; Angom, D. (Cornell University Library, 2014-05)
    We examine the dynamics of a vortex dipole in the Bose-Einstein condensates (BECs) of trapped dilute atomic gases at zero temperature in the presence of a Gaussian barrier potential. The density-anisotropy induced by the ...

  • Chakraborty, Rik; Maiti, Arnab; Sharma, Nikita; Dey, Krishna Kanti (Academic Press, 2021-09)
    The field of active matter is a nascent area of research in soft condensed matter physics, which is drawing on the expertise of researchers from diverse disciplines. Small scale active particles-both inorganic and ...
  • Aravind, K. et al. (Oxford University Press, 2021-02)
    Comet 2I/Borisov is the first true interstellar comet discovered. Here, we present results from observational programs at two Indian observatories, 2 m Himalayan Chandra Telescope at the Indian Astronomical Observatory, ...
  • Sengupta, Anand (IOP Science, 2015-03)
    The Advanced LIGO gravitational wave detectors are second-generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA, USA. The two instruments are identical in design, and ...
