Late-time evolution of charged massive Dirac fields in the Kerr-Newman background [PDF]

, 2006
We investigate both the intermediate late-time tail and the asymptotic tail behavior of the charged massive Dirac fields in the background of the Kerr-Newman black hole.

Search for radial velocity variations in eight M-dwarfs with NIRSPEC/Keck II [PDF]

, 2011
Context. Radial velocity (RV) measurements from near-infrared spectra have become a potentially powerful tool to search for planets around cool stars and sub-stellar objects. As part of a large survey to characterize M-dwarfs using NIRSPEC at Keck II, we

Cosmic Evolution with Early and Late Acceleration Inspired by Dual Nature of the Ricci Scalar Curvature [PDF]

, 2008
In the present paper, it is found that dark energy emerges spontaneously from the modified gravity. According to cosmological scenario, obtained here, the universe inflates for $\sim 10^{-37}$ sec.

Normal Globular Cluster Systems in Massive Low Surface Brightness Galaxies [PDF]

, 2007
We present the results of a study of the globular cluster systems of 6 massive spiral galaxies, originally cataloged as low surface brightness galaxies but here shown to span a wide range of central surface brightness values, including two intermediate ...

Discovery and quantitative spectral analysis of an Ofpe/WN9 (WN11) star in the Sculptor spiral galaxy NGC 300 [PDF]

, 2002
We have discovered an Ofpe/WN9 (WN11 following Smith et al.) star in the Sculptor spiral galaxy NGC 300, the first object of this class found outside the Local Group, during a recent spectroscopic survey of blue supergiant stars obtained at the ESO VLT ...

Outcome of Proximal Hypospadias Repair in Children using Standard Surgical Technique with Intermediate Vascularised Flap- A Retrospective Cohort Study [PDF]

Journal of Clinical and Diagnostic Research, 2021
Introduction: Hypospadias is a very common congenital anomaly noted in children with reported incidence of 0.4-8.2% in 1000 live birth. Treatment of hypospadias is urethroplasty, but is a difficult procedure due to complex anatomy, nonavailability of ...

Late-Time Tails in Gravitational Collapse of a Self-Interacting (Massive) Scalar-Field and Decay of a Self-Interacting Scalar Hair [PDF]

, 1998
We study analytically the initial value problem for a self-interacting (massive) scalar-field on a Reissner-Nordstr\"om spacetime. Following the no-hair theorem we examine the dynamical physical mechanism by which the self-interacting (SI) hair decays ...
