Complex Symmetry and Normality of Toeplitz Composition Operators on the Hardy space
Anuradha Gupta, Aastha Malhotra
In this paper, we investigate the conditions under which the Toeplitz Composition operator on the Hardy space becomes complex symmetric with respect to a certain co…
Black holes in the low mass gap: Implications for gravitational wave observations
Anuradha Gupta, Davide Gerosa, K. G. Arun +3
Binary neutron-star mergers will predominantly produce black-hole remnants of mass , thus populating the putative \emph{low mass gap} between neutron stars and…
On coupled best proximity points and Ulam-Hyers stability
Anuradha Gupta, Manu Rohilla
For two nonempty, closed, bounded and convex subsets and of a uniformly convex Banach space consider a mapping s…
Quasi-Fredholm spectrum and compact perturbations
Anuradha Gupta, Ankit Kumar
In this paper we explore some characteristics of the quasi-Fredholm resolvent set of an operator defined on an infinite dimensional Banach space . Moreover, in t…
Calibrating the cosmic distance ladder using gravitational-wave observations
Anuradha Gupta, Derek Fox, B. S. Sathyaprakash +1
Type Ia supernovae (SNe Ia) are among preeminent distance ladders for precision cosmology due to their intrinsic brightness, which allows them to be observable at high redshifts. T…
A new approach to coincidence and common fixed points under a homotopy of families of mappings in -metric spaces
Anuradha Gupta, Manu Rohilla
In this paper we derive coincidence and common fixed point results under order homotopies of families of mappings in preordered -metric spaces.
Testing the multipole structure and conservative dynamics of compact binaries using gravitational wave observations: The spinning case
Shilpa Kastha, Anuradha Gupta, K. G. Arun +2
In an earlier work [S. Kastha et al., PRD {\bf 98}, 124033 (2018)], we developed the {\it parametrized multipolar gravitational wave phasing formula} to test general relativity, fo…
Common Fixed Point results in Complex valued metric spaces via simulation functions
Anuradha Gupta, Manu Rohilla
In this paper, the notion of -simulation function is introduced and the existence and uniqueness of common fixed points of two self-mappings satisfying contractive cond…
A new characterization of generalized Browder's theorem and a Cline's formula for generalized Drazin-meromorphic inverses
Anuradha Gupta, Ankit Kumar
In this paper, we give a new characterization of generalized Browder's theorem by considering equality between the generalized Drazin-meromorphic Weyl spectrum and the generalized…
Effect of orbital eccentricity on the dynamics of precessing compact binaries
Khun Sang Phukon, Anuradha Gupta, Sukanta Bose +1
We study precession dynamics of generic binary black holes in eccentric orbits using an effective potential based formalism derived in [M. Kesden et al., PRL {\bf 114}, 081103 (201…
The GstLAL Search Analysis Methods for Compact Binary Mergers in Advanced LIGO's Second and Advanced Virgo's First Observing Runs
Surabhi Sachdev, Sarah Caudill, Heather Fong +26
After their successful first observing run (September 12, 2015 - January 12, 2016), the Advanced LIGO detectors were upgraded to increase their sensitivity for the second observing…
