  • 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 ...
  • 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 (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 (IOP Science, 2015-01)
    We argue that the divergence in time for an 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 observer ...
  • Jana, Arghajit; Ricci, Claudio; Naik, Sachindra; Tanimoto, Atsushi; Kumari, Neeraj; Chang, Hsiang-Kuang; Nandi, Prantik; Chatterjee, Arka; Safi-Harb, Samar (Royal Astronomical Society, 2022-06)
    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). ...
  • Mondal, Shanwlee Sow; Sarkar, Aveek; Vaidya, Bhargav; Mignone, Andrea, (IOP Publishing, 2021-12)
    Interplanetary coronal mass ejection (ICME) shocks are known to accelerate particles and contribute significantly to solar energetic particle events. We have performed magnetohydrodynamic-particle in cell simulations of ...
  • Jana, Arghajit; Jaisawal, Gaurava K.; Naik, Sachindra; Kumari, Neeraj; Chatterjee, Debjit; Chatterjee, Kaushik; Bhowmick, Riya; Chakrabarti, Sandip K.; Chang, Hsiang-Kuang; Debnath, Dipak (IOP Publishing, 2021-06)
    We present the results obtained from detailed timing and spectral studies of a black hole candidate MAXI J1813-095 using Swift, NICER, and NuSTAR observations during its 2018 outburst. The timing behavior of the source is ...
  • Suthar, Kuldeep; Roy, Arko; Angom, D. (IOP Science, 2014-06)
    We examine the dynamics of a vortex dipole in the Bose–Einstein condensates of trapped dilute atomic gases at zero temperature in the presence of a Gaussian barrier potential. The density anisotropy induced by the barrier ...
  • 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 ...
  • Maksimova, Elizaveta A.; Barmin, Roman A.; Rudakovskaya, Polina G.; Sindeeva, Olga A.; Prikhozhdenko, Ekaterina S.; Yashchenok, Alexey M.; Khlebtsov, Boris N.; Solovev, Alexander A.; Huang, Gaoshan; Mei, Yongfeng; Dey, Krishna Kanti; Gorin, Dmitry A. (MDPI, 2021-09)
    Microbubbles are intravascular contrast agents clinically used in diagnostic sonography, echocardiography, and radiology imaging applications. However, up to date, the idea of creating microbubbles with multiple functionalities ...
  • Raj, Harsh; Bhushan, Ravi; Banerji, Upasana S.; Muruganantham, M.; Shah, Chinmay; Nambiar, Romi; Dabhi, Ankur J. (Elsevier, 2022-02)
    Corals growing in shallow oceanic regions record the radiocarbon variations in ocean surface waters. Tracing bomb radiocarbon in various carbon reservoirs, can help understand the pathways and rates of carbon exchange ...
  • Aadhi, A.; Apurv Chaitanya, N.; Jabir, M. V.; Vaity, Pravin; Singh, R. P.; Samanta, Goutam Kumar (Nature publishing group, 2016-05)
    Airy beam, a non-diffracting waveform, has peculiar properties of self-healing and self-acceleration. Due to such unique properties, the Airy beam finds many applications including curved plasma wave-guiding, micro-particle ...
  • Aadhi, A.; Apurv Chaitanya, N.; Jabir, M. V.; Singh, Ravindra P.; Samanta, Goutam Kumar (Optics InfoBase, 2015)
    We report on experimental demonstration of an all-periodically poled, continuous-wave (CW), high-power, single-frequency, ultra-violet (UV) source. Based on internal second-harmonic-generation (SHG) of a CW singly resonant ...
  • Roy, Soumen; Sengupta, Anand S.; et al. (American Physical Society, 2021-10)
    We report on an all-sky search for continuous gravitational waves in the frequency band 20–2000 Hz and with a frequency time derivative in the range of [−1.0,+0.1]×10−8  Hz/s. Such a signal could be produced by a nearby, ...
  • Sengupta, Anand (American Physical Society, 2019-07)
    We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast spinning neutron stars with an asymmetry around their rotation axis, using data from the second observing run ...
  • Sengupta, Anand (IOP Publishing, 2018-02)
    We present the results of a search for long-duration gravitational wave transients in the data of the LIGO Hanford and LIGO Livingston second generation detectors between $ \newcommand{\OOneStart}{{\rm 12 ~September ~2015}} ...
  • Roy, Soumen; Sengupta, Anand S. et al (American Physical Society, 2021-11)
    After the detection of gravitational waves from compact binary coalescences, the search for transient gravitational-wave signals with less well-defined waveforms for which matched filtering is not well suited is one of the ...
  • Sengupta, Anand (American Physical Society, 2019-05)
    We present the results of a search for long-duration gravitational-wave transients in the data from the Advanced LIGO second observation run; we search for gravitational-wave transients of 2�500 s duration in the 24�2048 ...
  • Sengupta, Anand (American Physical Society, 2017-09)
    We report on an all-sky search for periodic gravitational waves in the frequency band 20475 Hz and with a frequency time derivative in the range of [?1.0,+0.1]10?8??Hz/s. Such a signal could be produced by a nearby spinning ...
