  • Sahu, Suraj; Joshi, Bhuwan; Mitra, Prabir K.; Veronig, Astrid M.; Yurchyshyn, V. (American Astronomical Society, 2020-07)
    In this paper, we present a comprehensive study of the evolutionary phases of a major M6.6 long duration event with special emphasize on its pre-flare phase. The event occurred in NOAA 12371 on 2015 June 22. A remarkable ...
  • Vadawale, S. V.; Chattopadhyay, Tanmoy; Rao, A. R.; Bhattacharya, Debayan; Bhalerao, V. B.; Vagshette, N.; Pawar, P.; Sreekumar, S. (European Southern Observatory, 2015-06)
    X-ray polarimetry is largely an unexplored area of an otherwise mature field of X-ray astronomy. Except for a few early attempts during the 1970s, no dedicated X-ray polarimeter has been flown during the past four decades. ...
  • Singh, Balbeer; Thakur, Lata; Mishra, Hiranmaya (American Physical Society, 2018-05)
    We study the effect of a strong constant magnetic field, generated in relativistic heavy ion collisions, on the heavy quark complex potential. We work in the strong magnetic field limit with the lowest Landau level ...
  • Singh, Balbeer; Abhishek, Aman; Das, Santosh K.; Mishra, Hiranmaya (American Physical Society, 2019-12)
    We calculate the transport coefficients, drag, and momentum diffusion of a heavy quark in a thermalized plasma of light quarks in the background of a Polyakov loop. The quark thermal mass and the gluon Debye mass are ...
  • Kurian, Manu; Das, Santosh K.; Chandra, Vinod (American Physical Society, 2019-10)
    The heavy quark drag and momentum diffusion have been investigated in a hot magnetized quark-gluon plasma, along the directions parallel and perpendicular to the magnetic field. The analysis is done within the framework ...

  • Shaikh, Adiba; Kurian, Manu; Das, Santosh K.; Chandra, Vinod; Dash, Sadhana; Nandi, Basanta K. (American Physical Society, 2021-08)
    The heavy quark drag and momentum diffusion coefficients in the presence of both the collisional and radiative processes have been studied in a hot viscous QCD medium. The thermal medium effects are incorporated by employing ...
  • Singh, Balbeer; Mishra, Hiranmaya (American Physical Society, 2020-03)
    We study the effect of shear and bulk viscosities on the heavy quark transport coefficient within the matrix model of semi-QGP. Dissipative effects are incorporated through the first-order viscous correction in the ...
  • Prakash, Jai; Kurian, Manu; Das, Santosh K.; Chandra, Vinod (American Physical Society, 2021-05)
    The impact of momentum anisotropy on the heavy quark transport coefficients due to collisional and radiative processes in the QCD medium has been studied within the ambit of kinetic theory. Anisotropic aspects (momentum) ...
  • Bhattacharya, Kaushik; Chakrabortty, Joydeep; Das, Suratna; Mondal, Tanmoy (IOP Science, 2014-12)
    If the recent detection of B-mode polarization of the Cosmic Microwave Background by BICEP2 observations, withstand the test of time after the release of recent PLANCK dust polarisation data, then it would surprisingly put ...
  • Tripathi, Nidhi; Sahu, L. K.; Singh, Arvind; Yadav, Ravi; Karati, Kusum Komal (American Chemical Society, 2020-03)
    The Arabian Sea possesses an intense oxygen minimum zone because of high primary productivity. These important biogeochemical aspects of the Arabian Sea have led us to investigate air–sea exchanges over the region. The ...
  • Sengupta, Anand; Gaur, G. (American Physical Society, 2016-06)
    We present the high-energy-neutrino follow-up observations of the first gravitational wave transient GW150914 observed by the Advanced LIGO detectors on September 14, 2015. We search for coincident neutrino candidates ...
  • Aadhi, A.; Apurv Chaitanya, N.; Singh, Ravindra P.; Samanta, Goutam Kumar (Optical Society of America, 2014-06)
    We report the development of a compact, high-power, continuous-wave, single-frequency, ultraviolet (UV) source with extended wavelength tunability. The device is based on single-pass, intracavity, second-harmonic-generation ...
  • Apurv Chaitanya, N.; Aadhi, A.; Jabir, M. V.; Samanta, Goutam Kumar (OSA Publishing, 2015-09)
    We report on the development of a high-power, high-repetition-rate, fiber laser based source of ultrafast ultraviolet (UV) radiation. Using single-pass second-harmonic generation and subsequent sum-frequency generation ...
  • Paneliya, Sagar; Khanna, Sakshum; Utsav; Makani, Nisha Hiralal; Banerjee, Rupak; Mukhopadhyay, Indrajit (Elsevier, 2022-04)
    In the present work, we demonstrate an in-situ synthesis of phase-change material (n-hexacosane) loaded exfoliated-graphite nanosheets (EGPCM) by modified hydrothermal method, exhibiting high thermal stability over extended ...
  • Apurv Chaitanya, N.; Jabir, M. V.; Banerji, Jagannath; Samanta, Goutam Kumar (Nature Publishing Group, 2016-09)
    Hollow Gaussian beams (HGB) are a special class of doughnut shaped beams that do not carry orbital angular momentum (OAM). Such beams have a wide range of applications in many fields including atomic optics, bio-photonics, ...
  • Bhattacharjee, Srijit; Sarkar, Sudipta; Wall, Aron C. (American Physical Society, 2015-09)
    Standard methods for calculating the black hole entropy beyond general relativity are ambiguous when the horizon is nonstationary. We fix these ambiguities in all quadratic curvature gravity theories, by demanding that the ...
  • Sahu, Suraj; Joshi, Bhuwan; Sterling, Alphonse C.; Mitra, Prabir K.; Moore, Ronald L. (American Astronomical Society, 2022-05)
    We analyze the formation mechanism of three homologous broad coronal mass ejections (CMEs) resulting from a series of solar blowout-eruption flares with successively increasing intensities (M2.0, M2.6, and X1.0). The flares ...
  • Singh, Balbeer; Mazumder, Surasree; Mishra, Hiranmaya (Springer Verlag, 2020-05)
    We study the effect of the magnetic field on the collisional energy loss of heavy quark (HQ) moving in a magnetized thermal partonic medium. This is investigated in the strong field approximation where the lowest Landau ...
