  • Sengupta, Anand (American Physical Society, 2017-02)
    We present the results from an all-sky search for short-duration gravitational waves in the data of the first run of the Advanced LIGO detectors between September 2015 and January 2016. The search algorithms use minimal ...
  • Sengupta, Anand (American Physical Society, 2019-07)
    We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gravitational-wave transients with a duration ...
  • Sengupta, Anand (IOP Publishing, 2013-11)
    We report on an all-sky search for periodic gravitational waves in the frequency range 50−1000Hz with the first derivative of frequency in the range −8.9×10−10 Hz/s to zero in two years of data collected during LIGO's fifth ...
  • Sengupta, Anand (IOP Science, 2014-04)
    We report on an all-sky search for periodic gravitational waves in the frequency range 50–1000 Hz with the first derivative of frequency in the range −8.9 × 10−10 Hz s−1 to zero in two years of data collected during LIGO's ...
  • Sarkar, Sudipta (Springer International Publishing, 2017-02)
    Gravity being the manifestation of the curvature of spacetime can create regions which are inaccessible to a class of observers. An example of such a region is the event horizon of black objects which acts as a one way ...
  • Sahu, L. K.; Yadav, Ravi; Tripathi, Nidhi (Elsevier, 2020-12)
    Ambient concentrations of benzene, toluene, and carbon-monoxide (CO) were measured at a semi-urban site in western India during the year 2015. Monthly mixing ratios of benzene, toluene, and CO were in the ranges of 0.58�1.18, ...
  • Sengupta, Anand (IOP Science, 2016-02)
    The discovery of the gravitational-wave (GW) source GW150914 with the Advanced LIGO detectors provides the first observational evidence for the existence of binary black hole (BH) systems that inspiral and merge within the ...
  • Kumar, Girish; Mahajan, Namit (Cornell University Library, 2015-11)
    The semi-leptonic baryonic b→s decay, Λb→Λℓ+ℓ−, has been studied and new angular observables and asymmetries have been proposed which can test the presence of new physics beyond the standard model.
  • Kumar, Akash; Sengupta, Anand; Ganesh, Shashikiran (2015-02)
  • Kumar, Akash; Sengupta, Anand; Ganesh, Shashikiran (Cornell University Library, 2016-04)
    Physical Research Laboratory operates a 50cm robotic observatory at Mount Abu. This Automated Telescope for Variability Studies (ATVS) makes use of Remote Telescope System 2 (RTS2) for autonomous operations. The observatory ...
  • Kumar, Girish; Mahajan, Namit (American Physical Society, 2016-03)
    We calculate the zeros of angular observables P?4 and P?5 of the angular distribution of 4-body decay B?K?(?K?)l+l? where LHCb, in its analysis of form-factor independent angular observables, has found deviations from the ...
  • Hati, Chandan; Kumar, Girish; Mahajan, Namit (Springer Berlin Heidelberg, 2016-01)
    Recent experimental results from the LHCb, BaBar and Belle collaborations on the semitauonic decays of B meson, B¯¯¯¯→D(∗)τν¯¯¯, showing a significant deviation from the Standard Model (SM), hint towards a new physics ...
  • Hati, Chandan; Kumar, Girish; Mahajan, Namit (Cornell University Library, 2015-11)
    Recent experimental results from the LHCb, BaBar and Belle collaborations on the semitauonic decays of B meson, \bar{B}\rightarrow D^{(\ast)}\tau \bar{\nu}, showing a significant deviation from the Standard Model (SM), ...
  • Das, Diganta; Kindra, Bharti; Kumar, Girish; Mahajan, Namit (American Physical Society, 2019-05)
    We study the rare decay B?K?2(1430)(?K?)?+?? in the Standard Model and beyond. Working in the transversity basis, we exploit the relations between the heavy-to-light form factors in the limit of heavy quark (mb??) and large ...
  • Bhatt, Jitesh R.; Natwariya, Pravin Kumar; Nayak, Alekha C.; Pandey, Arun Kumar (Cornell University Library, 2019-05)
    The Experiment to Detect the Global Epoch of reionization Signature (EDGES) collaboration has reported an excess absorption dip in the 21 cm signal during cosmic dawn era. The stronger than expected 21 absorption signal ...
  • Bhatt, Jitesh R.; Natwariya, Pravin Kumar; Nayak, Alekha C.; Pandey, Arun Kumar (Springer, 2020-04)
    We have shown that in presence of a cosmic magnetic field the bounds on baryon dark matter cross-section (?^), dark-matter mass (md) and values of the magnetic field (B0) can strongly influence each other. This requires ...
  • Sengupta, Anand; Gaur, G. (Cornell University Library, 2016-08)
    The first direct gravitational-wave detection was made by the Advanced Laser Interferometer Gravitational Wave Observatory on September 14, 2015. The GW150914 signal was strong enough to be apparent, without using any ...

  • Poswal, H. K.; Tripathi, Ravi; Garg, Nandini; Deo, M. N.; Sharma, Surinder M.; Ghalsasi, Pallavi (IOP Publishing, 2012)
    Recent discovery of colossal negative thermal expansion (NTE) behaviour in Silver Hexacyanocobaltate Ag3[Co(CN)6] has triggered interest among researchers to understand the basic mechanism causing such an unusual behaviour. ...
