  • Tripathi, Nidhi; Sahu, L. K; Patel, Kashyap; Kumar, Ashwini; Yadav, Ravi (Springer, 2021-01)
    Non-methane volatile organic compounds (NMVOCs) play key roles in local and regional atmospheric chemistry as precursors for the production of ozone and secondary organic aerosols. Ambient air C2-C5 NMVOCs were measured ...
  • Atkinson, Oliver; Bhardwaj, Akanksha; Englert, Christoph; Ngairangbam Vishal S.; Spannowsky, Michael (Scuola Internazionale Superiore di Studi Avanzati (SISSA), 2021-08)
    We devise an autoencoder based strategy to facilitate anomaly detection for boosted jets, employing Graph Neural Networks (GNNs) to do so. To overcome known lim itations of GNN autoencoders, we design a symmetric decoder ...
  • 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 ...
  • 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 ...
  • Jaisawal, Gaurava K.; Naik, Sachindra; Epili, Prahlad R.; Chhotaray, Birendra; Jana, Arghajit; Agrawal, P. C (Scientific Research Publishing, 02-10-21)
    We present the results obtained from analysis of two AstroSat observations of the high mass X-ray binary pulsar OAO 1657-415. The observations covered 0.681–0.818 and 0.808–0.968 phases of the ∼10.4 day orbital period of ...
  • 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 ...
  • 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 (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 (Wiley-VCH Verlag, 2017-01)
    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. ...
  • Ghalsasi, Pallavi; Poswal, H. K.; Tripathi, Ravi; Garg, Nandini; Deo, M. N.; Sharma, Surinder M. (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. ...
  • Khanna, Sakshum; Marathey, Priyanka; Utsav; Chaliyawala, Harsh; Mukhopadhyay, Indrajit (AIP Publishing, 2018-05)
    We present the studies on the structural properties of monolayer Bidisperse silica (SiO2) nanoparticles (BDS) on Silicon (Si-100) substrate using spin coating technique. The Bidisperse silica nanoparticle was synthesised ...
  • Sengupta, Anand (American Physical Society, 2016-10)
    The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers. In this paper, we present full results ...
  • Sengupta, Anand (American Astronomical Society, 2019-09)
    We present results on the mass, spin, and redshift distributions with phenomenological population models using the 10 binary black hole (BBH) mergers detected in the first and second observing runs completed by Advanced ...
  • Sarkar, Sudipta (2020-12)
    Prof. Roger Penrose was awarded one-half of the Nobel prize in physics 2020 "for the discovery that black hole formation is a robust prediction of the general theory of relativity." Penrose�s landmark work on singularity ...
  • Fairoos, C.; Ghosh, Avirup; Sarkar, Sudipta (American Physical Society, 2018-07)
    We study the entropy evolution of black holes in Lovelock gravity by formulating a thermodynamic generalization of the null Raychaudhuri equation. We show that the similarity between the expressions of entropy change of ...
  • Majumder, Barun (Springer Link, 2013-11)
    Here we study the effects of the Generalized Uncertainty Principle in the tunneling formalism for Hawking radiation to evaluate the quantum-corrected Hawking temperature and entropy for a Schwarzschild black hole. We compare ...
  • Sarkar, Sudipta (Springer, 2019-05)
    Black holes have often provided profound insights into the nature of gravity and the structure of space�time. The study of the mathematical properties of black objects is a major research theme of contemporary theoretical ...
