    On August 17, 2017, the Advanced LIGO and Advanced Virgo gravitational-wave detectors observed a low-mass compact binary inspiral. The initial sky localization of the source of the gravitational-wave signal, GW170817, ...

    On August 17, 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system. The detection of this gravitational wave signal, GW170817, ...

    The transport coefficients such as shear viscosity, bulk viscosity, and thermal conductivity of a magnetized hot QCD matter have been estimated in the strong field limit. To model the hot QCD matter in the presence of ...
  • Rindani, Saurabh D.; Singh, Balbeer (Cornell University Library, 2018-05)
    We examine the possibility of using single-Higgs production at an e+e− collider with polarized beams to measure, or constrain, indirectly a possible anomalous triple-Higgs coupling, which can contribute to the process via ...

    Blazars outburst provide an opportunity to study their spectral behaviour, correlated variations, and structure of the jet. Such an unprecedented flaring activity in FSRQ CTA102, during 2016 - 2017, is used for a detailed ...

    The evolution of the black hole horizon can be effectively captured by a fictitious membrane fluid living on the stretched horizon. We show that the dynamics of this boundary matter arises from the invariance of the bulk ...

    It has been pointed out that there exists a tension in σ8−Ωm measurement between CMB and LSS observation. In this paper we show that σ8−Ωm observations can be used to test the dark energy theories. We study two models, (1) ...

    We study origin, consequences and testability of a hypothesis of `partial μ-τ' reflection symmetry. This symmetry predicts |Uμi|=|Uτi| (i=1,2,3) for a single column of the leptonic mixing matrix U. Depending on whether ...

    Exclusive semileptonic decays based on b→s transitions have been attracting a lot of attention as some angular observables deviate significantly from the Standard Model (SM) predictions in specific q2 bins. B meson decays ...

    Quantum Hall (QH) states of 2D single layer optical lattices are examined using Bose-Hubbard model (BHM) in presence of artificial gauge field. We study the QH states of both the homogeneous and inhomogeneous systems. For ...
  • Sengupta, Anand (Cornell University Library, 2018-02)
    The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitational waves. While general relativity allows ...
  • Sengupta, Anand et al., (Cornell University Library, 2018-02)
    We report on a new all-sky search for periodic gravitational waves in the frequency band 475-2000 Hz and with a frequency time derivative in the range of [-1.0e-8, +1e-9] Hz/s. Potential signals could be produced by a ...
  • Fairoos, C.; Ghosh, Avirup; Sarkar, Sudipta (Cornell University Library, 2018-02)
    We study the entropy evolution of black holes in Lovelock gravity by formulating a thermodynamic generalization of null Raychaudhuri equation. We show that the similarity between the expressions of entropy change of the ...
  • Parikh, Maulik; Sarkar, Sudipta; Svesko, Andrew (Cornell University Library, 2018-01)
    We find a local first law of thermodynamics, ΔE=TΔS−W, connecting gravitational entropy, S, with matter energy and work. For Einstein gravity S is the Bekenstein-Hawking entropy, while for more general theories of gravity ...
  • Kurian, Manu; Chandra, Vinod (Cornell University Library, 2017-09)
    Hot QCD medium effects have been studied in the effective quasi-particle description of quark-gluon plasma. This model encodes the collective excitation of gluons and quarks/anti-quarks in the thermal medium in terms of ...
  • Chakraborty, Sumanta; Ghosh, Avirup; Sarkar, Sudipta (Cornell University Library, 2017-09)
    Physical process version of the first law of black hole mechanics relates the change in entropy of a perturbed Killing horizon, between two asymptotic cross sections, to the matter flow into the horizon. In dynamical ...
