  • Natwariya, Pravin Kumar; Bhatt, Jitesh R.; Pandey, Arun Kumar (Springer, 2020-08)
    The effective theory of large-scale structure formation based on CDM paradigm predicts finite dissipative effects in the resulting fluid equations. In this work, we study how viscous effect that could arise if one includes ...
  • Bhadari, Naval Kishor; Dewangan, L. K.; Pirogov, L. E.; Ojha, D. K. (American Astronomical Society, 2020-08)
    We present an analysis of multiwavelength observations of Monoceros R1 (Mon R1) complex (at d ~760 pc). An elongated filament is investigated in the complex, which is the most prominent structure in the Herschel column ...
  • Bhattacharya, Arpan; Das, Saurya; Haque, S. Shajidul; Underwood, Bret (American Physical Society, 2020-08)
    We compute the circuit complexity of scalar curvature perturbations on Friedmann-Lemaitre-Robertson-Walker cosmological backgrounds with a fixed equation of state w using the language of squeezed vacuum states. Backgrounds ...
  • Jana, Arghajit; Chatterjee, Arka; Kumari, Neeraj; Nandi, Prantik; Naik, Sachindra; Patra, Dusmanta (Cornell University Library, 2020-08)
    We present the results obtained from a detailed X-ray timing and spectral analysis of the Seyfert 2 galaxy NGC 6300 by using observations from the Suzaku observatory, theChandra X-ray Observatory and the Nuclear Spectroscopic ...
  • Bhattacharya, Sukannya; Mohanty, Subhendra; Parashari, Priyank (American Physical Society, 2020-08)
    For primordial black holes (PBHs) to form a considerable fraction of cold dark matter, the required amplitude of primordial scalar perturbations is quite large (P?(k)?10?2) if PBH is formed in radiation epoch. In alternate ...
  • Swain, Abinash (Springer, 2020-08)
    In this work, our prime objective is to study non-locality and long range effect of two body correlation using quantum entanglement from various information theoretic measure in the static patch of de Sitter space using a ...
  • Biswas, Ayan; Mclver, J.; Mahabal, A. (IOP Publishing, 2020-08)
    A network of three or more gravitational wave detectors simultaneously taking data is required to generate a well-localized sky map for gravitational wave sources, such as GW170817. Local seismic disturbances often cause ...
  • Sengupta, Anand S. et al. (American Physical Society, 2020-08)
    We report the observation of gravitational waves from a binary-black-hole coalescence during the first two weeks of LIGO's and Virgo's third observing run. The signal was recorded on April 12, 2019 at 05?30?44 UTC with a ...
