  • Roy, Soumen; Sengupta, Anand S. et al.; Arun, K. G. (American Physical Society, 2021-03)
    The higher multipoles of gravitational wave signals from coalescing compact binaries play a vital role in the accurate reconstruction of source properties, bringing about a deeper and nuanced understanding of fundamental ...
  • Basak, Tanushree; Coleppa, Baradhwaj; Loho, Kousik (Springer Nature, 2021-06)
    We revisit the two real singlet extension of the Standard Model with a Z2�Z'2 symmetry. One of the singlet scalars S2, by virtue of an unbroken Z'2 symmetry, plays the role of a stable dark matter candidate. The other ...
  • Sengupta, Anand (IOP Publishing, 2017-09)
    We present the results of a semicoherent search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1, using data from the first Advanced LIGO observing run. The search method uses details of the ...
  • Roy, Soumen; Sengupta, Anand S. et al. (American Physical Society, 2021-07)
    We report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with upper limits from the earlier O1 and O2 runs. ...
  • Sengupta, Anand (American Physical Society, 2016-11)
    We report here the non-detection of gravitational waves from the merger of binary–neutron star systems and neutron star–black hole systems during the first observing run of the Advanced Laser Interferometer Gravitational-wave ...
  • Sengupta, Anand (American Physical Society, 2017-03)
    A wide variety of astrophysical and cosmological sources are expected to contribute to a stochastic gravitational-wave background. Following the observations of GW150914 and GW151226, the rate and mass of coalescing binary ...
  • Jauhari, Smita; Parekh, Kinnari; Pai, K.B.; Upadhyay, Ramesh V. (National Association of Corrosion Engineers, 2010-08)
    Nanomagnetic fluid (ferromagnetic nanoparticles) which has been evaluated as a corrosion inhibitor and the corrosion behavior of carbon steel in 1 M sulfuric acid (H2S04) is discussed. The nanomagnetic fluid was synthesized ...
  • Kumar, Vipin; Srivastava, Mudit K; Banerjee, Dipankar P. K.; Joshi, Vishal (Oxford University Press, 2021-01)
    SU Lyn, a star that ostensibly appears to be an unremarkable late M type giant, has recently been proposed to be a symbiotic star largely based on its hard X-ray properties. The star does not display, in low-resolution ...
  • Midhun, M.; Ramesh, R. (Springer, 2016-03)
    Stable oxygen isotope ratios (δ18O) of tree cellulose and speleothem carbonate are useful proxies for past monsoon rain in many tropical regions, as a decrease in rain δ18O is observed with increase in rainfall on a monthly ...
  • Mallika, Chinmay; Chandra, Naveen; Venkataramani, S.; Lal, Shyam (Elsevier, 2016-05)
    Atmospheric carbonyl sulfide (COS) is a major precursor for sulfate aerosols that play a critical role in climate regulation. Recent studies have highlighted the importance of COS measurements as a reliable means to constrain ...
  • Laskar, Fazlul I.; Pallamraju, Duggirala; Veenadhari, Bhaskara (Terra Scientific Publishing Company, 2014-08)
    Comprehensive behavior of the low-latitude upper atmosphere during sudden stratospheric warming (SSW) events at varying levels of solar activity has been investigated. The equatorial electrojet (EEJ) strength and the total ...
  • Prabhakar, Shashi; Salla, Gangi Reddy; Aadhi, A.; Perumangatt, Chithrabhanu; Samanta, Goutam Kumar; Singh, Ravindra P. (American Physical Society, 2015-08)
    We have considered optical beams with phase singularity and experimentally verified that these beams, although classical, have properties of two-mode entanglement in quantum states. We have observed the violation of Bell's ...
  • Ghosh, Snigdha; Samanta, Subhasis; Ghosh, Sabyasachi; Mishra, Hiranmaya (World Scientific Publishing, 2019-06)
    We have attempted to review on microscopic calculation of transport coefficients like shear and bulk viscosities in the framework of hadron resonance gas (HRG) model, where a special attention is explored on the effect of ...
  • 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 ...
  • Bhatt, Jitesh R.; Mishra, Arvind Kumar; Nayak, Alekha C. (American Physical Society, 2019-09)
    The EDGES experiment has detected the global absorption signal of the 21 cm line at z ∼ 17 in cosmic dawn era and reported its amplitude larger than the standard cosmological prediction. One possible explanation requires ...
  • Atreya, Abhishek; Bhatt, Jitesh R.; Mishra, Arvind (IOP Publishing, 2018-02)
    Self interacting dark matter (SIDM) provides us with a consistent solution to certain astrophysical observations in conflict with collision-less cold DM paradigm. In this work we estimate the shear viscosity (η) and bulk ...
  • Atreya, Abhishek; Bhatt, Jitesh R.; Mishra, Arvind (IOP Publishing, 2019-02)
    The viscosity of dark matter in cosmological models may cause an accelerated expansion and when this effect is sufficiently large, it can explain the dark energy. In this work, attributing the origin of viscosity to ...
  • Bansal, Anshika; Mahajan, Namit; Mishra, Dayanand (Springer, 2022-02)
    Charged current semi-leptonic decays of B-meson are important for a precise determination of the CKM elements. The CKM elements |Vub| and |Vcb| show a discrepancy between the exclusive and inclusive determinations. These ...
  • Harish; Vijayan, S.; Mangold, N.; Bhardwaj, Anil (American Geophysical Union, 2020-07)
    We report new exposures of water?ice along the scarps wall located within craters in the northern mid?latitude region of Mars using high?resolution imagery and spectral data of Mars Reconnaissance Orbiter. The exposed ...
  • Bhagwat, Ameeya A.; Vinas, X.; Wyss, R.; Schuck, P. (World Scientific Publishing, 2010-04)
    We propose to use the semi-classical Wigner-Kirkwood ħ expansion to calculate shell corrections for spherical and deformed nuclei. The expansion is carried out up to fourth order in ħ. A systematic study of Wigner-Kirkwood ...
