  Dutta, Manoranjan; Narendra, Nimmala; Sahu, Narendra; Shil, Sujay (Cornell University Library, 2022-02)

  The nature of neutrinos, whether Dirac or Majorana, is hitherto not known. Assuming that the neutrinos are Dirac, which needs B?L to be an exact symmetry, we make an attempt to explain the observed proportionality between ...
• Bounding the boundless: constraining topological Gauss-Bonnet coupling from GW150914 

  Chakravarti, Kabir; Ghosh, Rajes; Sarkar, Sudipta (Cornell University Library, 2022-01)

  Recent gravitational wave observation based on the data from GW150914 has firmly confirmed Hawking's area theorem and estimated the increase in total horizon area during a merger process of two Kerr black holes. We use ...
• The prospect of distinguishing astrophysical objects with LISA 

  Rahman, Mostafizur; Bhattacharyya, Arpan (Cornell University Library, 2021-12)

  The famous no-hair theorem dictates that the multipole moments of Kerr black holes depend only on their mass and angular momentum. Thus, the measurement of multipole moments of astrophysical objects through gravitational-wave ...
• Signature of non-uniform area quantization on black hole echoes 

  Chakravarti, Kabir; Ghosh, Rajes; Sarkar, Sudipta (Cornell University, 2021-12)

  A classical black hole is characterized by a horizon that absorbs radiation of all frequencies incident on it. Perturbation of these black holes is well-understood via exponentially damped sinusoids known as quasi-normal ...
