  • Are H 0 and σ 8 Tensions Generic to Present Cosmological Data? 
    Bhattacharyya, Archita; Alam, Ujjaini; Pandey, Kanhaiya L; Das, Subinoy; Pal, Supratik (IOP Publishing, 2019-05-10)
    Yes, for a wide range of cosmological models (ΛCDM, non-interacting wz CDM, wz WDM, or a class of interacting DMDE). Recently there have been attempts to solve the tension between direct measurements of H0 and s8 0m W from ...
  • The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: measurement of the BAO and growth rate of structure of the luminous red galaxy sample from the anisotropic power spectrum between redshifts 0.6 and 1.0

    We analyse the clustering of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spectroscopic Survey Data Release 16 luminous red galaxy sample (DR16 eBOSS LRG) in combination with the high redshift tail of the ...
  • COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses*,**, XII. Time delays of the doubly lensed quasars SDSS J1206+4332 and HS 2209+1914 
    Eulaers, E; Tewes, M; Magain, P; Courbin, F; Asfandiyarov, I; Ehgamberdiev, S; Rathna Kumar, S; Stalin, C. S; Prabhu, T. P; Meylan, G; Van Winckel, H (EDP Sciences, 2013-05)
    Aims. Within the framework of the COSMOGRAIL collaboration we present 7- and 8.5-year-long light curves and time-delay estimates for two gravitationally lensed quasars: SDSS J1206+4332 and HS 2209+1914. Methods. We ...
  • COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses. XIV. Time delay of the doubly lensed quasar SDSS J1001+5027 
    Rathna Kumar, S; Tewes, M; Stalin, C. S; Courbin, F; Asfandiyarov, I; Meylan, G; Eulaers, E; Prabhu, T. P; Magain, P; Van Winckel, H; Ehgamberdiev, Sh (EDP Sciences, 2013-09)
    This paper presents optical R-band light curves and the time delay of the doubly imaged gravitationally lensed quasar SDSS J1001+5027 at a redshift of 1.838. We have observed this target for more than six years, between ...
  • H0 from ten well-measured time delay lenses 
    Rathna Kumar, S; Stalin, C. S; Prabhu, T. P (EDP Sciences, 2015-08)
    In this work, we present a homogeneous curve-shifting analysis using the difference-smoothing technique of the publicly available light curves of 24 gravitationally lensed quasars, for which time delays have been reported ...
